Hi,
I would like to point out a problem with the PG32UCDM. I have issues with the image signal on several units of the PG32UCDM. A white artifact often appears on the screen for a brief moment (one second), which I suspect, depending on the refresh rate, either only appears in the top right corner (120Hz) or the entire lower half of the screen (240Hz). Sometimes the monitors lose the signal completely for a brief moment. As soon as the signal comes back, the Dolby Vision logo appears again in the top right. I have experienced the problem with 3 PG32UCDM units (MCM105 & MCM106 firmware). The issue occurs randomly on one screen at a time. The problem occurs with the cables that came with the monitors and also when AMD FreeSync is disabled.
A Reddit user also reports he has the same issue with his unit. I have attached a picture from the Reddit user that shows the glitch. The Reddit user reports that he is experiencing glitches via HDMI1. For me, the issue occurs via DisplayPort (I rarely use HDMI, so I can't say whether the isue also occurs with my PG32UCDMs via HDMI). Both I and the Reddit user have Dolby Vision enabled. I also had the issues before the Dolby Vision update (MCM105). My PG32UCDMs are connected to an AMD Radeon RX 7900 XTX via DisplayPort. The Reddit user connected his PG32UCDM to an Xbox Series X via HDMI.

Hi @ScaryBandana ,
Thank you for contacting us.
To help us better troubleshoot your display issue with white images, we would like you to confirm the following:
Providing this information will help us locate the problem more quickly.

Hi,
The problem occurs completely randomly, whether when playing games or watching a YouTube video.
The black screens only occur very rarely, maybe once every 1 to 2 weeks, whereas the white glitches occur daily multiple times.
The glitch always occurs either in the top right corner or in the entire lower half of the screen. I strongly suspect that the refresh rate influences the position of the glitch. One PG32UCDM runs at 240Hz and the glitch always occurs in the entire lower half, and another PG32UCDM only runs at 120Hz and the glitch only occurs in the top right corner. I had another PG32UCDM that was replaced because of a problem with the stand, this one also had the problem with the glitch, it also had the glitch in the top right corner (because it only ran at 120Hz).
The glitch occurred since day 1 with FW MCM101.
All drivers are up to date. The monitor has also already been reset. That doesn't solve the problem.
Unfortunately, I don't have a video because, as I said, the problem occurs too randomly and for too short a time to record it.
Hardware: ROG CROSSHAIR X670E HERO, AMD Radeon RX 7900 XTX (MBA model), AMD Ryzen 7950X3D, Windows 11 24H2 (Build 26100.2605), AMD Adrenalin Edition 24.12.1.
I'll send you the serial numbers via DM.

Hi,
I have now been able to record a video of the problem.
In the video, the FPS counter of the monitor OSD is positioned above the location of the glitch, so you can see that the problem is occurring behind the monitor OSD, this could possibly be helpful internally in narrowing down the problem. The monitor in the video is connected with the included ROG USB-C cable.
Another important piece of information is that I only bought the PG32UCDM visible in the video last week, and it has been running smoothly for the entire last week, with no static noise and no black screens. Both problems started today. According to OLED Usage Info, the third unit ran for 51 hours and went through 19 pixel cleaning cycles before the problems started.
However, I also had a PG32UCDM unit in the past that was delivered with a defective stand and therefore only stayed with me for a maximum of 2-3 days before it was replaced, and this unit had these problems since day 1.

Hello,
In the past two days the glitch occurs very often to my PG32UCDM with the HDR disabled and I have black screens as well.
During watching Netflix on Windows app I get black screen and then the video is completely gone with only the subtitles keep on playing.

I noticed that the frequent glitching was occurring after an Nvidia driver update and it stopped being so frequent after the latest as of now Version: 572.42 - Released: Thu Feb 13, 2025. It still occurs tho but not that frequently.
The Netflix black screens started with the same driver describing above but they didn't stop with the latest.
When I'm using the monitor with my MacBook Pro 14 M1 Pro I haven't noticed the glitch at all. So this is making me thing that is a driver issue or conflict with the monitor and the GPU.

I am having this same issue using HDR10, so Dolby Vision is not the culprit for me. It just began this week while playing Dragon Age Veilguard, but also persists into using Windows. I am on the current Nvidia drivers. I have tried replacing the Display Port Cable but that did not resolve the issue. I am on MCM105. Disabling HDR in Windows (windows alt b) seems to resolve the issue, but obviously that is not an acceptable long term solution.
