Asus XG27AQDMG Discussion

New firmware released.

It seems to have at least fixed the black crush at 240hz @ 2.2 gamma. I can now see square 5 with wcg + clamp.

I'll look for more undocumented fixes.

Things look a little less orange/yellow in HDR? Still have to do the six color toggle fix though.

Hey Guys, this thread has been super helpful but i have one question regarding novideo_srgb clamping: i have the icc Profile from the product page active in Windows and use the clamp in edid Mode, is this the right way to do it? Or does it Not Work with an icc Profile active?

I've had a love hate relationship with this monitor. Most of the issues are standard WOLED stuff but the very changeable grey uniformity is killing it for me.

One day it looks acceptable. Another it looks hideous with lines everywhere. Running those youtube randomised colour videos can clean it up. Running the pixel refresh does literally nothing. If anything it makes the problem worse.

My Sony TV is a WOLED and the uniformity doesn't change but I'm guessing this behaviour is normal for this monitor. Anyone got any opinions or ideas before I jump ship to another monitor?

Hello. Same problem here. Frankly, I'm disappointed with this monitor. There are too many flaws: the blacks are crushed at 240Hz without using novideo_srgb+clamp, uniformity and color accuracy are bad, the color banding/posterization effects is absolutely atrocious. And it's unbelievable that we are now in 2026, and they still haven't managed to fix the VRR flicker at 240Hz. OLED Anti-flicker reduction helps a little but not totally, and it also causes a little stuttering and blacks are crushed even more. And besides, over time, vertical white lines appeared on a grey background, covering my entire screen; I don't know if it's because of pixel cleaning doing this with time… I'm thinking to change it for tandem oled monitor if it's better at the future.

If you use the ICC profile, then applications that support ICC will get double-clamped (once by the ICC, once by novideo_srgb.)

There is no reason to use the ICC profile if you use nv_srgb.
