PG32UCDM inversion artifacts?
Posted: 18 Mar 2024, 03:30
I see vertical "scan lines" on my PG32UCDM QD OLED and I believe these are inversion artifacts.
Symptoms are:
At 240Hz with or without VRR - I see them in some dark places in games during motion. As motion stops, they dissapear. It's very difficult to detect them at first place if you don't know they exist and where to look. But I tested VRR flickering in Cyberpunk 2077 and carefully observed dark areas, that's how I noticed these lines and now I can easily make them appear and see them.
At <100Hz/FPS with VRR activated - they appear in more places (but also dark) and also in static content! I made a video with them in a Cyberpunk 2077 screenshot. I wanted to add the link to this video, but I'm not allowed to add an external link to this post.
Are these lines inversion artifacts?
I thought this was only an issue with old TN monitors.
I made a post on Reddit where I asked people to check this phenomenon. Most of them told me they had nothing, but I think I just didn't explain well enough what to do to notice them.
On one german forum, I asked people to check this on their PG32UCDM. And two people who really reproduced the conditions I described were able to detect them.
I also saw several reports with a very similar issue on other QD OLED monitors from MSI and Dell.
