Asus PG27AQDP HDR Problems

[Malicium]

Hello,

I bought this display, when I started watching HDR movies I noticed "color banding".

Then I ran greyscale ramp from AVS forum to further investigate and it was obvious... just look at the pictures.

Display firmware : MCM102

OS : Windows 11 2024 H2

Motherboard : asrock z370 mini itx

Nvidia drivers : 565.90

I tried hdmi and display same problem. I tried with both to reset the display to default same problem...

I tried forcing in nvidia control panel 10 bits same problem....

Adjusting the brightness doesn't resolve the problem.

I tried different os different drivers I tried everything...

OSD shows HDR in monitors I tried every mods.

I hope you can help.

Mine also looks like this after looking at some gradiant grayscale photos, havent noticed this issue during actual use...Are all oled ****** or what?

It is normal, i had two of these monitors and all had the same issue. You can change gamma a bit to make it better but then u have more black crush. All WOLED Panels have these issues to some extent.

Hi, I have the same problem, maybe even more visible. Extreme posterization and color banding with HDR enabled. Did you manage to get it fixed somehow?

[Malicium]

Hello, unfortunately not, I send it back and waiting for a firmware update... On my lg c2 tv there's no problem so woled panel shouldn't look like this...

Is there an option for smoothing gradation on the monitor at all? I know that banding on OLED TVs is quite common with HDR content, so they have clarity functions that smooth out the banding sometimes called gradation smoothing. I think if you turn these monitors off, they also do some kind of auto correction features. Maybe try turning it off then back on.

Hello, nope there's no smoothing gradation setting with this monitor...
