Playing with my Seiki se39uy04. Got it to do 1440p at 60hz. Playing with other custom stuff. - Page 7

post #61 of 894
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 1080p@120Hz and 720p@240Hz 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?

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.

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.

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.

The display has a built in 2560x1440 60hz EDID
