MAJOR POST REVISION/REDO

Ok, so here is what is going on with the panel nowadays.

My exact setup is as follows:

i7 2600k
asrock extreme4 z77
r9 290
Catalyst 14.2 beta
16gb of ram
seiki se39uy04

Once I downloaded and installed drivers I used amd pixel patcher to patch the HDMI spec.

I then downloaded Toastyx's custom resolution utility.

BEFORE Adding anything with toasty's CRU I suggest adding the resolution. I don't know the steps on how to do it on NVIDIA. In order to add any resolution into CCC that you want follow these steps:

1. Run regedit with administrative privileges.
2. Navigate to your 2d Driver file path. The path can be found in CCC under information: software. It should be under hkeylocalmachine/system/controlset001/control/class/ (the last part of the path is specific to each driver version).
3. Click on it and double click the reg file titled "DALNonStandardModesBCD2"
4. Edit this file.

The syntax in the file may seem a little confusing. The first four numbers are for the horizontal resolution, the next four numbers are the vertical resolution. The next eight numbers are for color settings that I am not going to get into. The final two numbers are for refresh rate. Leave the refresh rate 00, as this will make windows search for all driver level added refresh rates.

For example, if I wanted to add 3200x1800 I would type:

32 00 18 00 00 00 00 00 00

Regedit will add another line automatically once all fields are populated.

5. NOW YOU CAN ADD THAT RESOLUTION TO CRU. Your TV should accept any signal that is added via the registry at any refresh rate as long as the pixel clock is under 295mhz. I believe this is a firmware limit, but I am not sure. The hardware limit should be 315mhz.

YOU MUST HAVE GPU SCALING OFF FOR THESE CUSTOM RESOLUTIONS. Scaling by the TV varies greatly. For example, 3200x1800 looks better than 1440p for me and waaaayyy better than 1080p. If I change the resolution to 3216x1809 it scales horribly and looks worse than 1080p.

WHY IS THIS IMPORTANT?

You can change existing resolutions to higher refresh rates as long as the pixel clock is under 295mhz.

Resolutions that are tested and passing a UFO blur test and scale well for me:

3840x2160 @ 33hz
3200x1800 @ 47hz
2560x1440 @ 72hz
1920x1080 @ 125hz

If something doesn't scale well for you:

I'm not lying to you, as ae-?a has pointed out, some seiki 39 inch panels seem to work differently than others. Also make sure you flash your firmware to the 50 inch version. This did improve scaling for me.

My advice: see what looks good on your panel. At the very least, you should be able to get a few more hz out of the panel using this trick. I'm sure other resolutions work fine, I just haven't tested them. If you have something that works well and you think looks good let me know and I'll test them and add it to this OP.

If the 50 inch firmware doesn't work for you, try this custom one made by ae-?a

Since it is a TV, it will not be real 120hz, but rather adding frames to imitate 120hz. I have never in my life heard of a true 120hz TV sadly. So you will probably only get 60hz.

The seike 4K TV does [email protected] or [email protected] Also there is the skyworth TV that was able to pass a frameskip test at [email protected] There is also some TVs that overclock to true 120hz when the motion interpolation is turned off.

Several models manage to support true 120Hz from a computer, but this is usually undocumented.

I have thus been unsuccessful in getting 120hz on my tv. I think it is a firmware issue that seiki plans on updating on an indefinate "soon". The 50 inch model does get true 120hz though.

I am just glad to get 1440p at 60hz out of the thing. The TV properly recognizes it once the EDID is forced to it via Toasty's CRU. There just seems to not be any way to get the TV to cooperate in any kind of 120hz at over 720p.

I am going to shoot for other things as well. Anyone know a good test for 120hz?


The Scaler does not handle resolution above 1920x1080 correctly unless you got some newer panel or something.

I have gone into this in detail on hardforum which nobody seemed to believe initially that things are just getting interpolated down to 1080p then upscaled to 4k:

50 inch:
http://hardforum.com/showpost.php?p=1040268394&postcount=590

39 inch:

http://hardforum.com/showpost.php?p=1040274952&postcount=603

Honestly I am surprised that nobody found this horrible scaling so obviously horrible of the several people who said they ran at 1440p and it was 'working' as I do not consider that to be 'working.'

My last email from Seiki on the 13th of November was:

I have some movement on our end. Our engineering team says they can address the issue easily, but they would like to get their hands on the test signal that you used to generate the artifact issue. Is this something you can send to us?

(The refresh rate multi-tool which I gave them a link to). Not totally sure why they called it an 'artifact' issue as its a frame drop issue, LOL.

salamachaa 11-17-2013 03:40 PM

I don't know honestly. The panel itself put itself in a 2560x1440p mode that was programmed into it but unreachable by other means. The picture is noticeably sharper than running in 1080p mode. Have you tried flashing your firmware lately? I just flashed it Friday. There are two different firmwares on their site for the same model. The only difference seems to be options it enables in the menu.

Can you take a picture with a camera or something very close to text or something? that should make it pretty obvious...

I am using the one from 08/28 which is the newest one they published. I actually got that one in my correspondents with seiki before they had it on their site. Since the 39 and 50 inch both have this issue I would be amazed if you did not unless its doing video card scaling but then it would only be 30 Hz (not 60).

salamachaa 11-17-2013 04:27 PM

This is a shot from the only camera I have (an htc one). I took the picture directly next to the tv as close as I could get. One is at 1080p and one is 1440p.

IMAG0113.jpg 847k .jpg file

IMAG0112.jpg 821k .jpg file

A little side note:

I tried GPU scaling on and off and it did NOT change the refresh rate. My panel identified it as 2560x1440 60hz both times and blur busters ufo test came up as valid 60hz both times.

Sorry it took me a while to response by the way. I wanted to test 720p 1080p and 1440p to make sure it was not artifacting in any of them. I also wanted to make sure I was getting the correct refresh rate.

No problem but they are quite blurry unfortunately so its a bit hard to tell although it seems quite a bit better than what I had.

Can you go in the service menu and tell me what the panel info is? Mine says:

Also can you paste me the exact timings you used for 2560x1440 in the custom resolution program? Even though its blurry yours didn't seem as bad as mine so curious whats going on. Just let me know if any of the values for the above are differen't (you don't need to type any of yours out).

The blurry was from the camera. I apologize. I assure you there is no hocus pocus going on. It looks like we have a different board revision perhaps.

So I the seiki 39 inch my dad just got from amazon (he got a second one from home). The scaling is still CRAP on it. It looked somewhat better than it did for me on linux simply because windows is using bigger font sizes (96 DPI default) than my linux machine which is set to 75 DPI. So a little less noticable but definitely crap compared to video card scaling, definitely still scaling it down to 1080p then upscaling it...

I don't know what to tell you.. There is a marked improvement for me between 1440p and 1080p. It really doesn't seem scaled on mine. Does your television recognize that you are sending it a 1440p signal?

ae-?a 11-21-2013 06:47 PM

I don't mean to be refuting you say. I really would like to verify what you say is true and the scaling is good maybe with newer revisions. Its definitely 1440p as the display even says 2560x1440p. Ive seen this on three different 39 inch seiki's and one 50 inch (a fourth coming as my dad got a second one for home). So far its been pretty bad on everyone I tested. It was very obvious to my dad too as the blacks aren't any where near black. Here is a lossless 75-dpi terminal text which does not have anti-aliasing (when they are aliased it seems to come out better):

http://box.houkouonchi.jp/seiki_terminal_test.png

Can you tell me if all that text looks fine/is easily readable? Especially the bolded part like being able to see the circle in the center of the b and the a in 'dekabutsu' ? If you could take another close-up picture (it really doesn't need to be as close as you got it but like 1.5 inches away or something of a big grouping of text at smaller size (instead of a single letter) would be helpful. Even if you have to get even farther away whatever it takes to be in focus. I understand if you dont want to go through the trouble of this. I took the pictures of mine via an iphone 5 (so not a great camera) but they came out pretty decent.

Also if you look at this image:

http://box.houkouonchi.jp/seiki_39/checkered_640x480_2.png

And compare it with another computer or at 3840x2160 does it still look similar or does it look like the the last one I posted in this picture:

http://hardforum.com/showpost.php?p=1040274952&postcount=603

I would really like to find out if the scaling is actually ok on some models of the 39 inch (as I am sure others will as well). I would love to verify your results and I hope yours really does have much better scaling than the ones I have tested so far.

Also I take it if you enable GPU scaling and thus the dipslay says 3840x2160 but the OS is outputing 2560x1440 (so video card scaling) that it looks pretty similar if its enabled/disabled? I know on mine the video card scaling looks *WAY* better.

Giving you strait PNG's i think is more of an apples to apples comparosin (so your looking at the same things I am) rather than comparing other stuff.

Even better yet look at this screenshot:

http://box.houkouonchi.jp/seiki_39_scale_test.png

These are anti-aliased fonts but compare to what the picture looked like for me (especially the text on the vew bar:

Koogiking 11-21-2013 08:20 PM

Do you have to use the Custom Resolution utility to achieve 2560 x 1440? Can you not just set it through Catalyst Control Center or windows without any extra edid overriding.

Here is the part that is confusing to me. When I have GPU scaling on I stay in 2560x1440 mode. The resfresh rate stays 60hz. I am going to add some pictures I took of mine in 1440p mode. They really look nothing like yours. Also the terminal is perfectly readable both close up and standing a good 10 feet away.

I have three random trouble shooting things that you could try.

1. I actually removed the 4k default entry from CRU. I only have the 1440p and now I added the 2160p one as a secondary entry.
2. What firmware have you been using? There are two entries for the 39 inch one. I know they are supposed to be for two different revisions of the same TV, but they really just enable certain settings in the setup. If you are having trouble with one, consider flashing the other.
3. Are you on the same video driver as me? I am on catalyst 13.9 ( a couple versions old).




Again, sorry for the ****ty pics. My phone gives some odd halo and grainy effects on high light sources. The grid is actually a little less pronounced of black lines IRL. However, as you can see, no plaid type effect.

I had to use EDID overriding. CCC did not recognize 1440p before this, even though the panel has a 1440p mode. You also have to unlock the pixel clock.

Thanks for taking those. Those images are much better to see whats going on. I really don't see how drivers could effect this at all to be honest. Your panel seems to be handling the scaling a lot better than mine

Ok looking at your pics it still seems like the scaling is pretty poor to me (extremely washed out) but for whatever reason it is quite a bit better on yours than it is on mine. Notice how all your texts are basically turning completely grey and stuff? definitely messed up scaling IMHO. I took a picture of the same area of that image file.

Here is the native scaler (as you can see quite a bit worse than yours):


IMG_0134-small.JPG

But here is just using the zoom (beryl/opengl scale filter) which is pretty comparable to videocard scaling. IMHO that scaling looks *way* b
etter than the seiki's. I will totally admit your seiki for whatever reason is doing quite a bit better job than mine but is still not very good. I

IMG_0132-small.JPG

I am using the firmware with the backlight-fix stuff which I though tyou were as well? I guess I could try the other one when I get a chance.. Honestly I didn't take pictures when I tested the new one my dad got but I updated to the same firmware I have now and I want to say the scaling did seem a bit better than mine (I chocked it up to larged font sizes of windows); however I am now thinking his was possibly scaling like yours does which still looks much crappier than it should IMHO. Atleast it looks like yours is not losing like half of its resolution like mine seems to in the process its just somewhat poor scaling. Way more livable of an option than what mine was doing though.

salamachaa 11-21-2013 11:09 PM

IMHO the scaling is fine on my panel. It looks the same as other panels I have with similar dpi. Also there is no grey issue. I think it is just you looking at a picture of a screen that is a cell phone picture of a screen and trying to get too much info from it. Anyway good luck figuring out your panel.

Can you post a step by step instruction on how to do this? I'm probably going to buy this today or tomorrow and it would be great to use 1440p on Windows 8

Also does this monitor still have overscan issues at 60hz non native resolutions?

I am assuming you mean overscanning too much when at other 16:9 aspect ratio resolutions. In that case, no. As far as a guide:

Go to: http://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU?page=1
Download the AMD pixel patcher
run it
restart
download toasty's custom resolution utility.
run toasty's custom resolution utility.
Edit the top profile to be 2560x1440 60hz.
Restart
Change the resolution in CCC

Thanks man. I just order the monitor too. Should be coming on Wednesday

I just went to Nvidia control panel and hit custom resolution and typed in 2560x1440 and 60hz... The same thing no?
Or is this just what u had to do to get it working at the res with AMD...Thanks

Not the same thing. You have to unlock the pixel shader clock using the nvidia one on the site. Then you should be able to override it via nvidia control panel.

Go to: http://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU?page=1
Download the AMD pixel patcher
run it
restart
download toasty's custom resolution utility.
run toasty's custom resolution utility.
Edit the top profile to be 2560x1440 60hz.
Restart
Change the resolution in CCC

Just got the TV and followed these instructions. I have 1920 x 1080 @ 120Hz working on the 39 inch. I tested it and with the Hz tester and I don't get any dropped frames either. True 1920 x 1080 @ 120hz. I guess they fixed the issue with a firemware update and my new TV has it applied out the box

I was also able to get 2560 x 1440 @ 60z, BUT it is really really blurry. At 30Hz it isn't blurry. Does this happen on your end or no?

salamachaa 11-27-2013 05:06 PM

I have not. There was another user reporting the issue though. Not sure what causes it.

Hey guys I have been following this thread and was thinking about getting this monitor(tv). I am coming from a 6 year old 28" Hanns-G monitor so I would think that any of the new technology would look better to me than that did. I had 2 questions really. 1. Will I be able to do the 2560x1440 60hz with and AMD 6970 card? 2. Most of what I use the computer for is web browsing/online shopping/forum reading and a few games mostly of the MMO variety. Which resolutions would best serve those purposes? Is gaming on this set at either 1080p or 1440p fluid and visually appealing?

Thanks!

I do not have this issue. Another user in the thread reported it but blamed the TV and didn't want to try different things. Let me know if you figure it out.

What resolution is the Hanns-G monitor? I am using 2560x1440 on my 7950s. I don't see why it wouldn't work on a 6970. You should be able to do those games at 3820x2160. If you have input lag issues let me know. I have been able to play 3rd person games no problems with some tweaks in radeon pro. The desktop looks amazing at 4k and reading is definitely best at that resolution.

This is the TestUFO frame skipping test that you did?

Can you post a photograph (not screenshot) of an unbroken sequence of squares of www.testufo.com/frameskipping in either Chrome or Opera? The green colored "VALID" is only for the web browser, not for the monitor.

All known 39" SEIKI's do frameskipping for 1080p @ 120Hz.
Only the 50" SEIKI does 1080p @ 120Hz flawlessly.

cnvrtble98 11-29-2013 10:18 AM

thanks for the reply. My hanns g is 1920x1200. It was anyways...its dead! I have read so many different things about this monitor so I wanted to ask here. I read that it can do 2560x1440 at 60hz which I would think would be good for gaming unless input lag or some other issues arise. I'm thinking about upgrading my video card but figured I'd wait to see how I do first. Trying to decide if I should pull the trigger on the monitor but hoping for a little more feedback.

No problem, the 1440p support isn't a normal windows resolution for this panel. You have to manually add it and do the pixel patched like I had earlier in this thread. I am pleased with the panel. It definitely wasn't a trouble free solution though. It took a bit of troubleshooting to get what I wanted. If you don't plan on using the 4k, you may as well buy a proper 1440p Korean panel. It will have similar pixel denisity and will have better colors than this tv at 4k. It is a 39 inch tv so the pixels are more spread out than other monitors. It all depends on if you want something this big.

Ok got it. It really is the size that appeals to me. When I game on a console and my 63" plasma I normally sit in a chair that I place about 3 to 3.5 feet away from it lol. So I was figuring that this would be great for me. My hopes with this would be to get the largest 2560x1440 display possible for the price of this tv. I like to play games like Skyrim and will be playing the new Elder Scrolls Online once it comes out. If this would work well for those types of things then I will get it. I just don't see enough info giving me an answer either way.

Yeah I just tested again using the refresh rate multitool .exe and it turns out that it does have frameskipping. It's pretty severe too. Cant believe I didn't notice it. the first time

Is there anything in particular that you want to see? I am trying to think of how I can send you some video or something non compressed etc... Do you want some skyrim 4k video? I might be able to borrow a camera and get you some.

cnvrtble98 11-30-2013 06:18 PM

Lol no I don't need video. Can you actually play Skyrim at 30hz? I really just want to know how things look and how a game would look at 2560x1440. Will my idea of getting this as a useable monitor at that resolution 60hz. Sure I could just get a 27 inch qnix but I really want something bigger.

Skyrim is very playable at 30hz. On xbox360 that is the only option so it would have to be LOL.

cnvrtble98 12-01-2013 10:46 AM

Ok guys. I have decided to get this. Just hoping that someone can supply me with two things. The length and width of the base and the amount of clearance from the base to where the bezel of the monitor starts. I want to modify my computer desk because putting this on top of the monitor stand will make it a little too high. Thanks!

What is the firmware date/time on your seiki 39 inch?

Tthe 'really really blurry' would be how I describe the scaling as still being crap IMHO even on the newer panels.

Can you attach a photo of www.testufo.com/frameskipping ? Follow the instructions at the top. Thanks!

Also, the firmware date (Accesed via menus) would be useful, too!

Please attach those the firmware version and a valid test picture. If I could get that working on mine I would be super happy.

Seiki SE39UY04 at 3840x2160 with multiple monitors

 

How would Seiki SE39UY04 at 3840x2160 at 30Hz work with

  one X-Star DP2710 at 60Hz or
  two X-Star DP2710s at 60Hz (am guessing too slow)

if not gaming?

 

Are there issues with multiple monitors at varying Hz?

 

Have 4GB NVidia GTX 670, i7-3770K and 32 GB RAM.

I am going to shoot for other things as well. Anyone know a good test for 120hz?

I've read thru the posts and don't see a description of exactly how this is accomplished or what the results are. I'd be really interested in further clarification:
  1. Were special tricks or settings needed to get 2560x1440 at 60Hz? If so, what are they?
  2. Are the mouse blur artifacts people report at 30Hz gone or 'acceptable' to you?
  3. Are you still running at this rate and what's your experience been?

Thanks in advance!

If you search through the thread you can find the answers to your questions tongue.gif

I used toasty's cru and ati pixel patcher.

I do not run at 30hz nor have I for a long time. I know what you mean and I don't think they were artifacts. At 30hz, the mouse looks a little bit like a slide show going back and forth quickly. My mouse moves similarly to it did at 1080p, but it is clearer

I am running at the rate still, and I haven't had problems. My pictures don't look like other users, so I don't know what is different.

Ah, the pixel patcher and cru I saw mention of but didn't understand the significance. I'm a newbie on video clocks.

If I interpret this correctly you use pixel patcher to allow the clock rate to go higher and you use toasty's cru to enable the settings you need for your display.

Thanks.

Everything looks fantastic in 1440p.... outside of the dreaded blurry text. im wondering if its an AMD/Nvidia related issue. ive tried everything and no fix.

Its monitor scaling (if 60Hz) so it shouldn't be but not all seiki's are created equal in 2560x1440 scaling from what I have seen.

After scavenging the world wide web for a few days I don't think there's more than one report where 2560x1440p scaling may be different for the better. This thread is a top Google search for "Seiki 1440p" and no other user has surfaced with the same results as found by the TC.... I feel its more likely that there is a fix to bypass the automatic scaling and the TC found it by complete luck with his configuration and no idea how he solved our problem lol

Look at post 19 in this thread:

https://www.overclock.net/t/1442986/playing-with-my-seiki-se39uy04-got-it-to-do-1440p-at-60hz-playing-with-other-custom-stuff/10#post_21239382

I had an earlier model 39 inch and it 100% does not scale the same as newer 39 inch displays. The 2560x1440 scaling I have is absolutely horrible but its still decently bad on newer ones too (IMHO). Flashing with the 50 inch firmware generates even different results.

I'd like to see pictures. Were you looking at them side by side? Some various settings in the service menu may have differed in the other pronouncing the blurry effect OR the tv was plugged into a different computer altering the configuration, just a guess though.. as I still believe scaling is universally the same across all sets. I have the 50" firmware installed

ae-?a 02-11-2014 01:14 PM

Did you even click the link I put in my earlier post? There are pictures... plain as day. The OP even posted pictures of his in a more zoomed in area of the image. If you think that its a bad camera its not because of that because if you look at the full sized ones you can see the individual pixels in the pictures. It was definitely losing information in downscaling to from 1440p to 1080p and then upscaling back to 4k to be full screen, it looked *horrible*. The newer ones atleast scale better but its still really washed out and everything looks grey due to the bad scaling.

You don't think version or firmware makes a difference? here is the difference of 1080p scaling on the 39 inch with 50 inch firmware vs 39 inch:

39 inch:

50 inch firmware:

Your pictures in post 19 are identical to how my monitor looks with scaling. I don't see anywhere in post 19 where you uploaded pictures in comparison to your dad's display. The 50" firmware update does seem to provide different scaling there but I'm also not debating that.. it probably does that across ALL sets. My whole point is that TC seems to be an isolated case with better scaling leading me to believe all displays are the same and he's unknowingly patched the flaw.. possibly within CCC?

ae-?a 02-11-2014 04:25 PM

unless your doing GPU scaling (and thus the info button on your display says [email protected] even though its at 2560x1440 resolution) then it doesn't really make much of a difference what OS/computer/etc you are on.

My dad's display looks exactly like the ops picture... in the post I linked the ops picture is at the top of the post (which I quoted). He shows a zoom in in one of the menu's from a PNG snapshot of the picture I also physically took on my display. You can see that there is a huge difference between them.

stephenk 02-11-2014 04:42 PM

You didn't include a picture of your dad's display. You also said it still looks like crap while the original poster disagreed & blamed the quality on his phone. I already knew TC's was different. It's different from literally every other owner.. thus my reasoning.

stephenk 02-13-2014 06:55 AM

AVSforum's member has 1440p running at 72hz!! I fired it up with CRU and sure enough, the display shows it accurately with [email protected] and it passes all UFOtests. Score!

Koogiking 02-13-2014 11:15 AM

If only the scaling wasn't so horribly crappy at 2560 x 1440.

ae-?a 02-21-2014 03:52 AM

If anyone is interested I hacked up the seiki firmware for the 39/50 inch model:

http://box.houkouonchi.jp/seiki_firm/install.img

It has a modified EDID so it now has [email protected] and [email protected] built into it (as well as 24/25/30 Hz 4k modes). This is usefull for driver upgrades not needing to do inf updates and for using the display with devices that can output @ 120Hz 1080p but you can't set custom modes on (ps4, xbox? I dont know... do they exist)?

EDIT:
Oh, I almost forgot.. I also took out the YCbCR support in the EDID as this has been ******* with the colors for people and it seems some people have had issues disabling it so I removed it from the EDID on my firmware hack:

Does that fix the screen blanking issue too?

stephenk 02-27-2014 01:06 PM

Awesome! I'll give it a try when I get home

master0068 03-15-2014 03:13 PM

I'm not sure this makes any sense.

If he is getting 2560x1440 @ 60hz, but the scaling is on the GPU, things don't add up?

GPU scaling would mean it would be capped @ 30hz, since the Display would be doing 3840x2160 ?

And if the TV is doing it, how can it be set to GPU scaling?

I hope this is the case (as I want to use 1440p) but, seems unlikely.

Milestailsprowe 03-15-2014 11:31 PM

I'm really interested in this. I wanna be able to use 4k for desktop and 1440p for games. Will all the hacks and more has anyone been able to do this?

Yeah, people can do 1440p, but apparently it's garbage. The scaling is so bad (on the display) that it's worse than 1080p. And 1440p scaled on the GPU only does 30hz.

toxsickcity 03-20-2014 08:26 AM

Hi,

I like your timing for 2560x1440
compared to how I first had it.. your timings look good.


Can you help make a good timing for 2880 x 1620.. (as it's 3K)

I can do 1440p with gpu scaling at 60hz.

Edit: Scaling is better at 1440p than 1080p for me. I am using the 50 inch firmware flashed onto the 39 inch.

This is usefull for driver upgrades not needing to do inf updates and for using the display with devices that can output @ 120Hz 1080p but you can't set custom modes on (ps4, xbox? I dont know... do they exist)?

EDIT:
Oh, I almost forgot.. I also took out the YCbCR support in the EDID as this has been ******* with the colors for people and it seems some people have had issues disabling it so I removed it from the EDID on my firmware hack:

It was an issue some AMD users had where the TV would go black ever couple of minutes as if you are just connecting the HDMI or turning the display on or off.

All of those issues went away when I got my Nvidia 780 card though.

DeadlyDNA 04-05-2014 07:10 PM

Big thank you for this thread. I am going to try some of these tricks to see what i can get done. I seriously was considering getting 3 of these for eyefinity. However after testing i found that if i use any kind of adapter to say DVI,DP port it defualts to 1080p 60 or lower in CCC or Windows. I really like the viewing angles on these and the size. If i can run eyefinity with 3 of these at 1080p or even higher that would be awesome. I am already mulling over making a custom vesa stand/bar for these in portrait. If i can follow these instructions here and get them to work at higher resolution then i will go get two more.

Thank you again and i will post my results here. Also if anyone is using HDMI to DP/DVI on this seiki 39inch and has no issue going over 1080p let me know.

I don't think you can do three HDMI connections even with two active HDMI connections and still use eyefinity.

if i do it it will be

monitor 1 HDMI(tv/pc)
monitor 2 HDMI(tv side) to DP(pc)
monitor 3 HDMI(tv side) to DVI(pc)

When i use an adapter to make pc end DP or DVI i can only get 1080p 60hz max in windows. Its like it doesnt see the EDID information properly with an adapter

DeadlyDNA 04-06-2014 12:00 AM

Alright im doing some testing and playing around with your instructions. I am needless to say having issues but i think mine are related to the panel itself.

First and most annoying issue is:

1# When i try a custom resolution say 2560x1440 @ 60HZ it works most of the time on the desktop. When i get into a game and set it to that resolution it first defaults the panel to [email protected] If i make any changes for it to refresh the game full screen it then goes to [email protected] but then my crossfire drops and i am running only on one card.

What i think is happening is this. Original entry to full screen 3d application defaults to [email protected] scaled from 3d app. When i try to say turn off AA and the game engine reloads it resets video display and then my pc thinks its in windowed mode because the monitor literally shutdowns temporarily. Thus i get [email protected]60hz with only one card gpu utilized.

Its really frustrating because i cant get the 3d app in 60hz right at the entry. when i do get 60hz its not using but one video card.

#2 Sometimes setting the custom resolution in CCC doesn't work right. For instance say i want to go from [email protected] and select [email protected] it just kicks me back to original resolution like it failed. If i do it in steps, select [email protected] then apply, then select 60hz in CCC and hit apply it works.

#3 and final issue...

I am noticing the panel seems to have "HDTV" modes that really change the over all look of colors,brightness,and scaling.
If its using and of the "standard" or PC modes it quality wise looks excellent. but it always defaults to 30hz. It's like it has 2 whole different methods of image processing


Final note for me: I am able to obtain 3840x2160 now on HDMI,DVI,DP with adapters. So now i could use 3 of these for eyefinity!
My final hold up though is if i am going to constantly have issues getting 60hz to work in 3d apps or ever 120hz. I would like to be able to run lower resolutions for games that cannot achieve playable FPS in 4k eyefinity.

1. I haven't tried crossfire, so I can't comment on that.
2. Do you have gpu scaling on? If you shut it off, it seems to help with refresh rate issues.
3. Yeah the hdtv modes are annoying. I usually avoid this by using 1440p because there isn't a hdtv mode for it.

DeadlyDNA 04-08-2014 07:04 PM

UPDATE!

i got 4k eyefinity working on 3 39inch Seiki screens.

1. flashed all 3 to 50inch firmware.
2. installed the pixel patch - this unlocked resolutions on any cable/adapter hookup for me
3. (mod warning) i removed #16 pin on all my DVI adapter cables. (this disables the monitor polling issue where when you power one off or change resolutions it causes the display to be removed and reappear. This was causing havoc with AMD eyefinity and CCC)

hookup as follows
#1 HDMI out from tv >>>> DVI PC
#2 HDMI out from tv >>>> DVI PC
#3 HDMI out from TV >>>>DVI/Displayport adapter PC

11520x2160 landscape or 6480x3840 portrait.


I will be making custom monitor stands for these so i can put them in portrait. I would not recommend doing this setup for a few obvious reason unless your planning to downsize resolutions some. You have to reduce game settings in most cases to achieve a playable frame rate. I am running quad 290's in crossfire so i can benchmark lesser crossfire setups for people interested. Eyefinity has very little game support in itself so combined with insane resolution ive found even less games work. I would like to provide screenshots but they are too large.


Edit: wanted to say my ultimate goal is to run 1440p @ 60hz for now using your guide. 4k eyefinity will be used very little in gaming but for desktop is very insane if you need the workspace.

DeadlyDNA 04-08-2014 11:55 PM

Having 2 issues left on the seiki screens.

I get blanking on one screen sometimes when switching to a resolution. if i power off then back on it seems to fix the issue. I recall reading somewhere about blanking so i will investigate it.

other issue i have is one screen at 3840x2160 30hz on hdmi to dvi cable and DP adapter on the end is having some artifacts on the screen that looks like very light green snow. i will toy with this later and see if replacing the cables fixes it. or try and see if i can replicate on another screen to make sure mine is not failing or faulty.

I am posting here in hopes to keep Seiki information available on this thread to any who may work with this screen. Thanks!

If what you are saying is you are using a DP -> DVI adapter and then from the DVI connection -> HDMI then that is bad. Actually in general DVI -> HDMI adapters should not be used on these displays. If you are driving it from a DP port then get the right adapter:

My video card does not have a mini-DP port. Also because i am using a hard mod for pin 16 on DVI to disable monitor polling, i cannot use an hdmi to display port unless i find the pin out or possible way to hard mod it as well. Eyefinity is setup based on a group of monitors and when you switch resolutions on DP/HDMI ports, the display is removed from windows temporarily. This causes issue when i say load up Heaven benchmark, and it goes full screen initialization.During the time it takes the monitor to change resolutions windows removes the monitor temporarily and thus eyefinity disables temporarily. when the monitor is re-detected Eyefinity becomes active again. This causes a couple things to happen, first the screen blank and reset multiple times. During this temporary removal and replace my 3d app Heaven benchmark goes into a windowed mode, or a full screen mode. Then my benchmark runs only on a single card.

I cannot blame AMD or Eyefinity or Windows as a single cause, however i can blame the need for the display adapter/monitor to be removed and replaced thus, the hard mod is the only way i know of.

P.S. i would like to add, the monitor i have connected HDMI--->DVI(female)DVI(male)----> Diplay port does indeed show a snow/artifact effect only at 3840x2160 resolution. This may be an issue with my hardware(very likely) or some sort of issue with bandwidth on this irregular connection. I will obtain an HDMI to DP cable soon and see if it even corrects this. I cannot say exactly what the cause is right now(limited troubleshooting) However when i can dig into it more i will post it here in case the off chance someone else ends up doing this. My main choice for connecting this monitor this way, was the simple fact its all i had on hand, also it worked to my favor for the hard mod to stop the above outlined issue.

... So buy the DP versio of the adapter instead of the miniDP one? You still use an HDMI cable so you can still do the pin mod. A probably more proper fix is an HDMI detective. I know with HDMI detectives my dad is not having any weird eyefinity issues on his eyefinity 6 card using two accel active DP -> HDMI 1.4 adapters driving two seiki SE39UY04's.

billyboy8888 04-09-2014 06:05 PM

Do you guys think SE39UY04's internal could handle 4k at 60hz? Anyone could find out the processors used inside? Also whether if it will receive firmware upgrade to enable HDMI 2.0?
I hate mine without 60Hz, everything is so laggy!!!!

While it is not as good as 60hz, if you can enable vsynch it should help smooth it out some. Also, i found without vsynch i got the least amount of screen tearing when i used radeon pro to limit my fps to 60 with dynamic limit. they limited the hardware in this screen to only allow 30hz. If it could even do 60hz it would require 2 HDMI connections currently and it's not designed to do it.

Hope that helps some

Thanks for the advice. But I really want to know if the hardware itself is capable of 60hz 4k. The panel should be able to refresh at 4k 120hz. It's the panel controller and the processor that's the limiting factor. Hopefully the processor is not limited to 248832000 pixels per second, which is [email protected] or [email protected] If not, then a simple firmware is suffice to upgrade it to hdmi 2.0 and support [email protected]
Otherwise, I will sell it and buy the dell UP2414Q, which is IPS and support 60hz refresh rate.

The lagging and stuttering is really driving me nuts, even mouse cursors can't move around smoothly.

Hopefully the processor is not limited to 248832000 pixels per second, which is [email protected] or [email protected] If not, then a simple firmware is suffice to upgrade it to hdmi 2.0 and support [email protected]
Otherwise, I will sell it and buy the dell UP2414Q, which is IPS and support 60hz refresh rate.

The lagging and stuttering is really driving me nuts, even mouse cursors can't move around smoothly.

i am undecided yet on making custom portrait stands for these screens if i do i may take one apart. in doing so i can take photos if needed.

I hate mine without 60Hz, everything is so laggy!!!!


The internals cannot handle it. Seiki is releasing a 60hz version at some point.

The panel TCON is 4 channel LVDS which is not enough bandwidth for 60Hz at 4k. A guy on hardforums says they are making a new TCON so you could do 60Hz but honestly I am not holding my breath.

other issue i have is one screen at 3840x2160 30hz on hdmi to dvi cable and DP adapter on the end is having some artifacts on the screen that looks like very light green snow. i will toy with this later and see if replacing the cables fixes it. or try and see if i can replicate on another screen to make sure mine is not failing or faulty.

I am posting here in hopes to keep Seiki information available on this thread to any who may work with this screen. Thanks!

Just out of curiousity did you fix the blanking issue and green snow? If so, could you post your fix here for the internet to see?

Eyefinity is setup based on a group of monitors and when you switch resolutions on DP/HDMI ports, the display is removed from windows temporarily. This causes issue when i say load up Heaven benchmark, and it goes full screen initialization.During the time it takes the monitor to change resolutions windows removes the monitor temporarily and thus eyefinity disables temporarily. when the monitor is re-detected Eyefinity becomes active again. This causes a couple things to happen, first the screen blank and reset multiple times. During this temporary removal and replace my 3d app Heaven benchmark goes into a windowed mode, or a full screen mode. Then my benchmark runs only on a single card.

I cannot blame AMD or Eyefinity or Windows as a single cause, however i can blame the need for the display adapter/monitor to be removed and replaced thus, the hard mod is the only way i know of.

P.S. i would like to add, the monitor i have connected HDMI--->DVI(female)DVI(male)----> Diplay port does indeed show a snow/artifact effect only at 3840x2160 resolution. This may be an issue with my hardware(very likely) or some sort of issue with bandwidth on this irregular connection. I will obtain an HDMI to DP cable soon and see if it even corrects this. I cannot say exactly what the cause is right now(limited troubleshooting) However when i can dig into it more i will post it here in case the off chance someone else ends up doing this. My main choice for connecting this monitor this way, was the simple fact its all i had on hand, also it worked to my favor for the hard mod to stop the above outlined issue.

Thanks for the awesome info. I'm going to try to write a synopsis of how to get these guys working in eyefinity for the OP if you don't mind correcting any errors in my steps below.

1. Flash to 50 inch firmware.
2. Use pixel patcher.
3. Remove pin number 16 from DVI cables.
4. Using two DVI to HDMI cables and 1 active displayport to DVI to HDMI attach tvs to card.

Is that correct?

Also, what is your opinion on the best way to game at 4k on the TV is? At 30hz with vsync I was getting some input lag that was unbearable for me. Without vsync I was getting screen tearing. I found the best way was to use RadeonPro to lock the FPS to 31 (I overclocked my refresh rate to 33) and keep vsync on. This fixed input lag for the most part.

Do you have another way that you deal with screen tearing/input lag?

Also thanks for your other thread. It's awesome.

Oh boy, where to start lol. To be honest i have done so much i have completely forgotten about those issues except screen blanking.

i have since last posted done the following changes i know of

Windows 8 from win7
WHQL 13.12 drivers (helped the most with the screen blanking)
changed cables/adapters then went back to my old ones.
Flashed 39inch firmware to the seiki's the latest one with backlight in main menu control.(might be going back to 50'inch firmware though the sleep mode on the new firmware is driving me nuts)


I am probably missing something here. I think the blank screen issue is a video card/driver/overclocking issue. it could be something to do with the cable or signals? It has rarely happened now its not really a big deal. Given that i am overclocking and changing so many things i cannot say for sure.I do recall i had a lot of screen blanking with 14.3 beta drivers.

I apologize i don't have a "specific" answer frown.gif - i forgot about this thread because i got so excited to game and bench lol

It's all good. I was just curious if there was a specific reason for it. Did you fix your green snow issue by switching cables?

I should have came back and thanked you for this thread. I almost ended up spending way more on the dell 24inch/samsung TN panel 27inch. I know 30hz is a no go for most people. I couldn't bring myself to spend an insane amount of money for 4k technology that's still changing and maturing. My thread wouod be nonexistent if yours wasnt here.


No problem i will try to offer my help.
Step 1 -is not required but i would recommend due to 39'inch firmware having an annoying sleep timer that even when "off" still bugs me.
Step 2 - Required for me on AMD GPU's IF going to Eyefinity 3 of these.(this may change when they release a driver that doesn't have the pixel clock so low?)
Step 3 -Optional especially if people don't feel good about hardware mods. My reason for doing this was to stop windows from removing/adding a display when entering a game. It would cause various issues with hot plug detection where eyefinity would disable, or the game would run without crossfire.
Step 4 - Hardware dependent -was because i thought AMD R9 series only allowed to use 1 of the 3 ports(DVI,DVI,HDMI) I have since been told you can use the HDMI port and both DVI ports on an AMD R9 series GPU. Apparently, something like a 7970 does have that restriction, however the port arrangement could vary based on model?

I haven't got to mess with the vsynch/input lag much at all. Me personally i preferred Radeon Pro "dynamic" FPS limiter to 60FPS. I have not used proper vsynch yet because AMD 13.12WHQL drivers have broken vsynch on R9 series.

hope that helps some smile.gif

Deadly! did you get the 2560x1440p @ 60hz eyefinity working? an update would be awesome im trying to do the same thing you are but I cant afford any of the displays yet

Noah3210 04-23-2014 04:27 PM

also can you send some pictures of the 3 of the monitors next too each other?

Noah3210 04-23-2014 04:59 PM

yeah thanks I have been watching this thread for a long time I am really hoping to get that 1440p on the seiki 39" is perfect size monitor. I sent him a pm also
