I've noticed a strange issue on my couple-months old monitor. As seen in the screenshot below, dark pixels bleed over the bottom of the screen. I have a video of it as well, but for some reason the forum doesn't accept .mp4 files, but the video is just this corruption flickering up and down.

System info:
Monitor: Asus ROG PG34WCD 3440x1440 OLED. Purchased about 3 months ago. I also have a 27" 1440p VA monitor, but I don't use that as my primary gaming monitor anymore and did not notice this issue on it at all in the year that I used it.
GPU: ASUS Dual OC 4070 Super, connected to the OLED monitor via HDMI cable. The secondary 1440p monitor is connected via DisplayPort.
Driver: GeForce driver 576.02, previous 572.83. It's happened on both driver versions, so either it's not a driver issue or it's something that Nvidia hasn't fixed yet.
Game: Starcraft 2. I've only noticed it in this game, but it's the primary game I've been playing recently and it only happens intermittently, so there's a good chance it's just only happened in SC2 so far. Also, I look at the UI at the bottom of the screen far more often in SC2 than in any other game, so it may have happened in another game but I haven't noticed it.
Other possibly relevant info: I've noticed it mainly happens when I'm looking at a black or dark section of the screen (the black-out area of the map covered by the fog of war). The black pixels bleeds onto the UI. This screenshot was actually the first time I noticed it happening when I wasn't looking at a completely black section of the map.

If anyone needs more information or has any ideas to try, I'll do what I can when I'm back home with my setup.

Have you tried different refresh or resolutions?
 
If it's only happening when part of the screen is especially dark, I'd lean towards this being an HDR-related issue.

A quick search of your OLED's model indicates there's been widespread (and varying) problems reported with HDR, on that particular display.

Have you tried turning HDR off / on?


Have you tried different refresh or resolutions?
This, and also try another HDMI 2.1 certified cable.
It shouldn't be the cause, but I have seen display corruption and excessive flickering, from 'a bad cable'.


Personally, I'd also give updating the firmware a go.

No, currently just at 2560x1440p (SC2 doesn't support widescreen). Will try changing it to 1080p and seeing if it still occurs.

I have been experimenting with Windows HDR vs Nvidia HDR recently. I will see if it happens when HDR is completely off. It's my first time with an HDR monitor, and upgraded to Windows 11 to get the full functionality, so I'm still figuring it all out.

Will try this as well, if I have one. IIRC, I'm using the one that came with the monitor.

Thank you for this, I did a pixel refresh and cleaning and it didn't change, so I'll update the firmware, since it seems to address a similar issue.
 
Can You run Your game with lowest graphics settings possible and see if it's not a problem with some of the features in game? (it's just the idea).
 
Update, followed LabRat 891's advice and disabled Nvidia HDR for SC2, which seems to have fixed it. Did not see it at all over several more hours playing SC2.
