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.

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

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 3840x2160@30hz. If i make any changes for it to refresh the game full screen it then goes to 2560x1440@60hz 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 3840x2160@30hz 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 2560x1440@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 3840x2160@30hz and select 2560x1440@60hz it just kicks me back to original resolution like it failed. If i do it in steps, select 2560x1440@30hz 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.
