I searched this thread but no one has commented how it feels playing an FPS game like battlefield or CS with 1080P 120Hz

Can anyone comment how reactive it is? any lags ?

1) Input lag on this monitor is about 20+ ms, was long time ago when I played FPS, it's more than plenty for sim racing but requirements are different.
2) The monitor does not do 120Hz at 1080p w/o skipping frames. I am not aware of any 40"+ 4K monitors that support that currently.
Below are supported resolutions and refresh rates on this monitor. This is from manual, although 60Hz 4K HDMI1 is probably just a typo, spec does not support that.

I achieved this by simply saving the EDID information for each monitor to a file and then doing a EDID Emulation using the saved files as previously posted by Robert Jones (Thanks!) https://sites.google.com/site/ebobster/stuff/displayportblanking

This post is awesome, thanks ricky. I didn't even know EDID emulation was a thing - some years ago, when 720p HDTVs first arrived on the market, there were all kinds of issues using some models with computers, because they held incorrect EDID information.

I care. If you don't care, then that's fine - the rest of the thread doesn't need to know.

if that were true, than you'd already know that any resolution >60Hz will skip frames on all 4K panels, so few here bother with over clocking.

1080p will only run at 60Hz on the UHD420.

I play Battlefield 4, and it runs great - there's no noticeable lag.

I've had good results with using the "Super Resolution" setting in the monitor's menu to sharpen the 1080p image. The default of "OFF" is very blurry - but switch to "Medium" and you'll find that 1080p looks pretty good.

Unfortunately, it doesn't seem to be a "per resolution" setting - so once you switch back to the Windows Desktop at 4K, you'll want to switch it off again otherwise it degrades the image quality.

Thought I'd ask over here too if any UHD420 owner has observed any flickering.


I'm trying to see if it's a monitor defect or just bad quality control for the average monitor.

Don't remember reading any. Someone reported some short period of signal instability after sleep but that could be GPU or driver, I haven't seen even this on mine.

I see, two questions.

How long have you owned yours?

And what's the longest period of time, at one time that you've used the panel?
