I am running a newish PC ASRock B450M R2.0 with Ryzen 5 4500, 16GB DDR4, 256GB NVME, NVIDIA Quadro P620 2GB PCI-E X16, Windows 11 Pro 24H2 completely up to date BIOS, drivers. This is ~36 hour old clean installation, activated too.

Occasionally, while browsing the web using latest Firefox, only three or four tabs, or even at the desktop when NO browser is open (except Edge running in the background). the screen goes black for two full seconds, and then returns. There is no artificating that occurs around it. It is just like what happens when there has been a recoverable graphics driver reset or crash. Except in my Event Viewer logs, there is nothing that correlates to it. Reliablity Monitor shows no errors or crashes recorded. Windows Updates are all applied, nothing is being installed by Windows in the background (e.g. TrustedInstaller, MS component store, definition updates for Windows Security).

Since this installation, it has happened about eight or nine times, It happens with no rhyme or reason. I can't reproduce it. I am suspecting maybe there is a glitch with the Quadro P620 display port, disconnecting and resuming the signal. If this is the case, it is happening too quickly (e.g. 2 full seconds) for the monitor to respond to loss of signal with any OSD notification or enter standby.

Does NVIDIA driver maintain any kind of logs on the system that could log connects and disconnects, power management events? I did not see anything NVIDIA in Windows Event Viewer.


P.S. Hey remember when CRT monitors used to give you that electrostatic sizzling sound when the display signal was lost and went blank? Sometimes you could even feel it!

I went back and found my thread. It was Gsync not free sync.

Well I did some things within a few hours, so may not find out what was the problem. I previously said all drivers were up to date but that was not true. The NVIDIA graphics was the latest available from Microsoft Update (for that card) dated 2022, which I initially didn't question, figuring Pascal being 5 years old in 2022 should be a very stable driver for Quadro. But I went ahead and got the latest R550 driver from NVIDIA. And disabled FreeSync on the monitor. And then I swapped the Ryzen 5 4500 for the Ryzen 7 5700X I got from that Newegg deal with bonus Crucial 32GB DDR4 kit a few weeks ago.

So far so good. It hasn't happened since, but then again, it was intermittent to begin with. So maybe it is solved, maybe not. Time will tell. Thanks!

I've seen something similar happen due to electrical interference, monitor would go blank for 2 seconds when an electrical switch was used nearby (bathroom lights near the office room).

Should it happen again, try to observe if any nearby event correlates with the disruption. Obviously there's still a higher chance this was software related.

Just throwing in my experience, I had a dell do this with my 4080. I switched the DisplayPort cable to a hdmi cable and it stopped. There’s a lot of junk cables out there, particularly DisplayPort, and I suspect I had a junk one.

Yeah I thought about the cable and also I'm using one of those cheapo converter/adapters to connect HDMI monitor to the mini-DP of the Quadro. But I use this monitor, cable, and adapter for a year now, with a few different PC's I was working on and a few different graphics cards, as well as my main PC. Only thing really 'new' was this Quadro P620 I get from Ebay recently.

An EDID emulator could potentially help, it fixed an issue for me with a Matrox mini display port output going to an HDMI input on a monitor where I had no sound. Going down that rabbit hole trying to fix my issue there were instances of people using it to prevent monitors from randomly going blank. Something about the proper information not always being communicated with the handshake.

This is the one I got:
