Playing with my Seiki se39uy04. Got it to do 1440p at 60hz. Playing with other custom stuff. - Page 9

post #81 of 892
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.

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.

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 4k@30fps or 1080p@120fps. If not, then a simple firmware is suffice to upgrade it to hdmi 2.0 and support 4k@60fps.
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.

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