Hello everyone!!!
First of all, I apologize for my bad English and if in case I have wrong forum section.
Recently it happens that both in game and on the desktop (usually when I have any window open) the image on the screen glitches/flickers for an instant (further on I linked a video I recorded about this phenomenon), and then everything returns to normal.
This happens only on one of the two monitors I have connected, specifically the one set to 165Hz.
The setup used is as follows:
This phenomenon occurs both in Windows 10 (clean installation, no crack, no tweaking, no dubious tools and not activated) and in EndeavourOS where the phenomenon always occurs on the PHILIPS monitor @165Hz.
On Windows I re-performed the clean driver installation with the help of DDU, but nothing changed. I also used an HDMI 2.0 cable, but the phenomenon still occurred. Searching the internet I found a file.reg on reddit that was supposed to solve the problem by disabling Multi-Plane Overlays via windows registry, but nothing.
I downloaded benchmarks but they all run great. I got error free responses on the vram with both OCCT and memtest_vulkan(lasted 2 hours).Finally I took a look at the temperatures in the various games and benchmarks but everything is in the normal range.I then opened the pc, and took a better look at the HW just checking if the various connectors were well plugged in by reattaching the various connections but nothing. At last I tried checking the nvidia control panel (disabling in-game overlays) .
As for the monitor settings, I really don't know where to put my hand and whether to put it.
I also tried setting the pcie line from auto to gen3, and repeated the tests/benchmarks the pc would reboot, of course then I reset the bios.
Searching the net, I found that this kind of problem may also be due with some signal interference so I order a DP 1.4 cable for €15 which will arrive the next day.
In the meantime, I reset the monitor and also the nvidia control panel, where the 3d settings panel is reset and gsync is on. It occurs to me that I've had this kind of problem several times in the testing stages with OCCT, so I open it but don't start any stress tests, I just quickly switch tabs in the software because I formulate a rather peculiar theory.
Anyway I increase the speed of tab switching more and more and the phenomenon recurs, and with the phone I record everything and upload the video to youtube linked below ( 0:27 I put one of the many sections where the phenomenon occurs in slowmotion).
After recording the video it did flickering again on firefox (with HW acceleration) without artifacts, so I cross out the first option (sigh) and the flickering without artifacts does it even at 120Hz.
Still waiting for the new DP cable, I tried connecting the monitor to an old laptop via HDMI2.0 cable. The laptop in question is an HP 255 G5 with amd igpu. The laptop has linux mint on it and it detects the monitor and the maximum frequency reported is 144Hz. And the monitor performs excellently. So if you want, you can bypass the monitor as the problem.
New DP cable arrives, I uninstall the drivers with DDU, apply the cable and reinstall the drivers, nothing changes...
Always surfing the net I find some discussions that link this kind of phenomena to problems that usually arise when overclocking GPUs and then instability problems... So I go to techpowerup and I see the frequencies: the core clock at 1807MHz while the memory clock at 1875Mhz...
I immediately remember seeing in OCCT a while back a frequency that was touching 1900Mhz and something, so I repeat the test and as you can see from the screen below, the core frequency is almost 100Mhz higher than claimed, and I reiterate that I seem to have seen it above 1900Mhz but not above 2000...
Now I don't know if something like this is normal, since I have NEVER done any kind of overclocking to the board and seeing a boost that goes beyond that smells a bit fishy to me. Besides, the phenomenon of flickering + artifacting with chunks of the screen shrinking into a gray and white checkerboard I have only seen them in OCCT with core clocked at 500Mhz...
With kombustor running, the core clock actually touches 1912Mhz, but no flickering/artefacts are occurring
In the meantime, I also disabled accelerationHW in windows, but nothing changes.
The situation, as far as I'm concerned and single research leads me to think more of a GPU problem than a monitor/refresh rate problem, but not being an expert nor one with experience I wouldn't really know what to think. If there are any new developments I will continue to update the thread, hoping someone can also give me their opinion about it...
