Asus XG27AQDMG Discussion

No frame skipping.

You might see bright squares (frame duplicating).

Yep. Just like with the mouse cursor test, some squares are bright:

Also, I get the exact same behavior in the 240Hz mode if I edit it with CRU and reduce VT or the pixel clock. I would guess Asus ships the monitor with 180Hz timings that are not compatible with g-sync? The problem completely disappears if I disable g-sync in NVCP.

That's some quite interesting buggy behavior.
Perhaps I should relay this to ASUS themselves.

I tried customer support, but unfortunately they didn't seem very interested. I'm not sure they even understood what I'm talking about

Have you tried upgrading to the latest firmware?

Yes, there were two firmware upgrades since I bought this monitor. I went from MCM101 to MCM102 on day 1. Then to MCM103 when it was released and is still the latest version.

Hey, any of you also have that annoying issue in which the Monitor switch back to full brightness once it woke up from sleep ?
It has been mentioned on ASUS' forums, but as always, ASUS is anything but helpful and don't acknoledge this problem that is multiple months old at least.
This, as well as some other issues, makes me want to try another OLED or even switch back to IPS while It's still time to return it.

Yes, it sometimes fails to restore settings after waking up from standby mode. It's not just the brightness, but pretty much all image settings. When this happens, don't change brightness. Instead, turn the monitor off and on again with its power button. It will then restore settings correctly.

It's another firmware bug.

Is there any chance there would be a firmware update to address the crushed blacks?

Unlikely. From what I can tell, black crush is an issue with OLED in general:

Got it. Yea I was wondering because I also have the LG 27GS95QE, which actually does not have black crush even at 240Hz and I am trying to decide which one to keep.

Thank for the confirmation. Hopefully this will be fixed shortly..
Edit : Firmware MCM104 has released shortly after my reply, and this issue is stated as fixed !

I've tried the NoVideo_sRGB Black Crush fix for that XG27AQDMG Monitor, and it's kind of a perfect solution for me. In the Lagom Black Level, I can actually differentiate each Square now. Which makes the OLED Monitor even better in comparison to my previous IPS one.
I can't confirm that this solution is compatible with 10 bpc Color Intensity that I'm setting in the Nvidia Control Panel however. Or maybe the "Display Reset bug" mentioned above cause these unstable results or something. (It's a different topic, but I'm trying to reduce Color Banding).

Hi everyone!

Has anyone encountered this issue where grays show up strangely, almost as if they were compression artifacts? In this example, you can see the compression artifacts from the YT video on the IPS panel next to the ASUS, but the ASUS boosts them up like crazy. I haven't seen this happen on other content, but there a few reports on Reddit of people noticing this in games as well.

It happens regardless of modes (SDR, HDR, 8bit, 10bit, DSC ON, DSC OFF, tried it all). Latest firmware, MCM104.

Thanks!

Hey, please search online for a topic on Asus' ROG forum called "XG27AQDMG insane banding/posterization".
An user had the exact same issue I believe. I will (tomorrow) check the trailer from your screenshot on my Monitor to see how it look for me.

Edit : so I've checked this, and it looks very similar to yours on my unit. My old and cheap IPS Monitor looks better in comparison.
But I don't know if that "Banding" issue is because of a faulty unit or a weakness of OLED technology.
Because on my phone (Galaxy Note 9), that trailer video looks noticably worse compared to how it's displayed on the ASUS Monitor.
Also, using the Lagom Banding test page, setting the GPU color depth from 8 to 10 bpc does reduce the banding.
Perhaps lot of content, or evens games are limited to 8 bit color depth or something ? I don't know this topic at all, so I'm quite confused.

Does anyone know if it's another issue, or just an OLED weakness ?
