Seiki se39uy04 and se50uy04 firmware has disappeared?

Ask the user salamachaa if the firmware "Custom made by ae-to www.overclock.net" worked for him. In this thread

I tried 50" first and now am using modded by ae or whoever and the firmware works the best I have had. 120hz at 1080p native and tested with blur busters


Now I also have 1440p working at 60fps using my own custom timings but it isnt working for games. Looking for a solution. Wish there was custom firmware for this too

Use this:

http://www.monitortests.com/forum/Thread-AMD-ATI-Pixel-Clock-Patcher
http://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU

Free HDMI port, and simulates a VGA port, audio capability is lost, but is reversible.
I use the Nvidia patcher,
Be careful with the Custom Resolution Utility (CRU), use it with this guide:

after the change and restart the menu of games the new resolutions should appear ....

Which firmware is the best for Seiki SE39UY04 39" 4K model?

i bought it for friend and now i'm worry because if it's bad one then i will have problems.
He's going use for PC monitor for some construction blueprints.

I'm use "SE50UY04_20130528.zip"
https://www.dropbox.com/sh/vjoupvucumkjmeq/AABxVy4hp3kKC_hfZvoCukqGa?dl=0

OK I downloaded the zip and unarchived it. I don't see a install.img file anywhere. The closest I see is install_a that is a .exe file. I have a rMBP Mid 2012 I can get 1080p @ 60Hz with HDMI to miniDisplayPort. Then I plug the same HDMI cable into the HDMI port I get a "No Signal". I know my Macbook can drive this monitor because a friend has one and it worked at 4K @ 30Hz without an issue. Any help would be great.

What a frustrating situation.

Buddy of mine bought that new 12" Macbook with the USB-c port on it and has no problem using the display @ 4K. I went and bought a refurb immediately expecting it to just work, but no dice.

I'm running El Capitan on a MacBook Pro (Retina, Mid 2012) which has the nVidia 650m card, and simply get No Signal.

I have used this laptop on multiple other Seiki displays (50/55" 4K) with no problem. The only way I can get it to work AT ALL is to use firmware Seiki distributes for the 50", AND I have to use a mini-display port to HDMI adapter... that is to say that the native HDMI port does not work at all with this display. The adapter I have is the MacAlly MDHDMI4k, which is specifically designed for 4k.

I have installed SwitchResX and created a custom profile, etc. but nothing is working.

What I have noticed is one difference between this display and the larger one - the EDID.

On the larger display you have a block:

---

---

EXTENSION EDID BLOCK 2

---

---

DID-EXT: Display ID Extension:

---

(only partly interpreted)
DisplayID version........1.1

DisplayID Block Type = Detailed Timing Block type 1:
Detailed Timing #1 in Block
Mode = 3840 x 2160 @ 30.000Hz
Pixel Clock............. 297.00 MHz Non-Interlaced

Horizontal Vertical
Active.................. 3840 pixels 2160 lines
Front Porch............. 176 pixels 8 lines
Sync Width.............. 88 pixels 10 lines
Back Porch.............. 296 pixels 72 lines
Blanking................ 560 pixels 90 lines
Total................... 4400 pixels 2250 lines
Scan Rate............... 67.500 kHz 30.000 Hz

Is non-default Mode
Sync: Digital separate with
* Negative vertical polarity
* Negative horizontal polarity

DisplayID Block Type = ASCII String:
SwitchResX


That seems to make all the difference. Both displays have ALL of the same data in EDID block 1, as well as the exact same data in the Monitor Description blocks.

Looks like something was just left out on these. Guess that's why they are discontinued and have had their firmware removed from the web.

Really appreciative to any suggestions others may have.

Thanks,

I have the same problem. I'm lucky every now and then I get HDMI 3820 x 1080 @ 30Hz, but most of the time I get "No Signal." I am able to get 4K every 1:20 tries, but can only run with display and that 4K I can't use a 3rd monitor. I am able to get 1080p with a HDMI to thunderbolt adapter. If you or I find a fix please post. When I change the input or unplug the cable my screen flickers like when it detects a monitor change, but still get 'No Signal"

found it here, enjoy

OK I've seen that file before but it doesn't have se39uy04. Or what firmware are you flashing? I'm using an active adapter and it's working for my now 95% of the time. Just have to replug the cord back in.
