Asus Rog pg32ucdp corruption frames

[elurahu]

I have recently acquired this lovely monitor, but I’ve been having issues with intermittent corruption frame where the monitor for a single frame blinks garbled data as seen on the linked video. It usually happens during restarts, but has also occasionally happened in steady state like in a game. The monitor came with the MCM105 firmware. I have yet to try to upgrade to MCM106 as it doesn’t state anything about the issue. 

I have tried two different computers and it is the same issue. I’ve been using the DisplayPort 1.4 240hz 4K mode.

I have extensively tested CPU, memory and gfx for stability and errors. 

Im considering RMAing the monitor as this is definitely not normal. Is this something people have seen before and if so have you been able to fix it?

After investigating more it seems that it is everytime I change to a different resolution or refresh rate. If I keep the refresh rate low (i.e. 60 - 100) I get no corruption. I'm starting to suspect it might be related to the supplied cable.

Hi @elurahu ,

Thank you for your patience. To better assist you with this issue, we would like to confirm the following:

1. Cable testing: Have you tried replacing the display cable to rule out the possibility of a faulty cable?
2. Connected devices: In addition to the display, what other devices are you connecting your computer to? Are you using any adapters or hubs? If so, we recommend temporarily removing them to simplify the connection.
3. Firmware update: Please ensure that your display firmware is up-to-date. You can visit the ASUS website to check for and update the firmware.
4. Factory reset: We recommend that you reset the display to its factory settings to rule out any incorrect settings.
5. Graphics card driver: Please ensure that your graphics card driver is up-to-date.

Thank you.

Thank you for the reply. Let me try to address your questions.

1. I have tested with both the supplied DP and HDMI cables. Results are the same, except with the HDMI cable, I get a black screen once per day when playing games.

2. There are no connected devices besides the monitor. I have a keyboard and mouse connected to the PC and the HDMI/DP cable from the PC to the monitor. Nothing is connected to the monitor.

3. I have updated the latest firmware, but the issue persists.

4. I have reset to the factory settings, and the issue persists.

5. I am using the latest Nvidia graphics drivers.

The easiest way to "provoke" the corruption frames is by switching the refresh rate in Windows. From 240hz to 120hz, the corrupted frames will be shown. Switching from 60 to 120 or 120 to 240, it does not show.

I am using HDR and 10bit color in Windows 4k 240hz.

Hi @elurahu ,

Thank you for your reply and the video you provided.

After reviewing the video, we noticed that it does not fully capture your process of switching the refresh rate, nor the specific scenario of the display after the damaged frames appear.

To better understand the cause of the problem, please provide a complete video of the problem occurrence process, including:

1. The steps you take to switch the refresh rate.
2. The specific screen display after the damaged frames appear (e.g., flickering, color change, freezing, etc.).
3. Does the screen automatically return to normal after the damaged frames appear? If so, approximately how long does it take to recover?

Your detailed video will help our team to more clearly confirm the problem. (Please use MP4 format)

Thank you for your cooperation.
