Just got a new PG27AQDP a few hours ago, launched CS2 to test it out and immediately noticed heavy posterization effect and color banding, tried other games, same result. Also very noticeable in OS.
Done some tests and it's very visible on all colors no matter what brightness level is selected. I didn't manage to take good picture to show the effect, but it looks exactly like in thread that I've linked above. Basically looks like heavy static overlay effect. I've got a matte IPS monitor as secondary and if I pull up 2 grey pictures on it and on PG27AQDP side by side, while IPS looks flawless, Asus looks like a static mess.
Nothing I've tried made any difference. I've tried following:
- Both HDMI and DP cables that came with monitor (tried both 1.2 and 1.4 modes in settings for DP).
- I never use HDR but turned it ON for testing, same result with HDR ON/OFF
- DSC ON/OFF + Lowering refresh rate to 60 hz (My logic was that maybe compression rate is too high but same result at 60)
- All combinations of color depth/range/temperature
- Standard/Performance and Power Saving modes
- Resetting to factory settings
- Pixel refresh
- VRR ON/OFF
- ELMB ON/OFF
The last potential thing that I haven't tried yet is FW update. According to monitor info, I'm running FW version MCM104, I've checked on Asus page thinking maybe new one is available, and found that latest one is actually MCM103 which is weird. Am I running some beta FW that's not available to download? Should I try MCM103? If I will install MCM103 is there any risk since I wouldn't be able to update to MCM104? Any other suggestions are also welcome.
