PG32UCDM black screen during game sessions!!

[silverbolt81]

So i am having this issue since the day i bought the monitor.

At first it was happening during a certain game,the callisto protocol.

Now it is happening also in Destiny 2.

As i am playing these games with HDR on,after some time the screen goes black and i have to manually turn the monitor off and on again in order for the image to appear again.

I had at the beggining the factory firmware,after i updated to MCM102 and now i have the 103.

This issue seems to be consistent on all firmwares.

I know it is not related to my windows setup because on the same pc with a different monitor this does not happen.

I have my pg32ucdm connected via dp.

Any suggestion would be much appreciated!!

For me the black screen happens also on 566.14, same as described, few seconds and comes back. I noticed that it doesn't happen if I put the 4090 voltage on stock in afterburner, but that decreases the clocks. 

However if I put the game on my OLED television, I can have full voltage and overclock and I can play for hours no blackscreens whatsoever. So it's definitely the  voltage\overclocks strain higher clocks? Possibly higher bandwidth then possible, and dsc triggers? Monitor seems to have some issue with bandwidth\strain on the card. 

It's very weird that Asus is not releasing a FW fix for this? Pretty sure there is some OCP trigger point for the DSC which should be raised a little bit to prevent the blackscreens.

I need to see what the return policy is at Micro Center. Same issue. While gaming just the occasonal few seconds of black screen, maybe once very 5 - 15 minutes. Multiple computers, cables, games, etc.. Too  bad that tech support for this company is missing.

Hello everyone,

It is December 28, 2024 and after 2 days of reading the 46 pages of this forum and all the videos on redit, 
YouTube and learning about VRR and DSC, disport port, HMDI

The only workaround that I found was to let the screen at 120Hz and disable the DSC
I got no issue the first month using this screen and now I have this black screen every minute
I even try with an optical HDMI cable...

Hope Asus will do something for fix this issue

I have the ASUS ROG Strix XG27ACDNG 26.5inch 360Hz QHD QD-OLED Gaming Monitor - and it happens 1-3 times per hour on this screen whilst playing PUBG. Very annoying. Returned my first screen as thought it was faulty - but happens the same on the replacement.

Read this:

Firmware Fixes To Fix for VRR Blank Out Issues (Monitors Randomly Going Black For 2 Seconds) 

The range for Freesync Premium on the PG32UCDM is 48-240hz. That is the "hard" cutoff that Chief Blur Buster mentions in the post linked to above. It is when the frame rate goes below that threshold that you get monitor black out issues. 

There is something you can do if you are somewhat technical. You can use a utility like ToastyX's CRU and modify the minimum VRR to either 55HZ or somewhere up to 65HZ. He also mentions this in the post. Unfortunately, I am not on Windows anymore (CachyOS Linux) so I can't test it out. Would someone be willing to try it out on Windows to see if it mitigates the issue?

When i had black screens my framerate was high,above 100+ fps.

Never happened to me with framerates that low.

Interesting, I had the exact opposite happen. With VRR on and full screen,  it would black screen when the FPS dipped below 48. I turned off VRR in the OS settings and have not had an issue ever since and it has been 3 to 4 months now. I am using displayport.

I don't use VRR at all - disabled, no proximity sensor enabled, just HDR - 240hz and DSC enabled... Indiana Jones once the GPU is bit more stressed, does black out quickly.. seems to be combination of high voltage on the card together with this monitor having issues... 

Problem is, I connect it to my TV and all is good.. so it's definitely the monitor having the issues not the PC.

I think the culprit for the issues has to be the stress on the cable, since Indiana Jones pulls heavy wattage on the card, when I am monitoring it, if I crank the voltage of the card, it goes up to 450w+, and clocks going 3050+mhz on the 4090. Seems then the cable gets hotter and there is possibly stress for the monitor port, which trips some internal protection and causes it to OCP. I am guessing a mechanism for protection is tripping to quickly for no reason. That's why it only happens in some games, because other games might not produce such wattage and are fine and are prolly not tripping it. I suggest @asus to check this.

I see quite a bit of speculation here, some sounding informed, some guessing. I'd love to have the manufacturer weigh in. For me, this happens with both high frame rate (game) and low frame rate (just using the monitor for productivity/os uses) and on multipe OSs.

Well, unfortunately manufacturer doesn’t give a ****** about the issue…
