[SOLVED] Weird flickering, already tried some things but can't figure out a solution. Is my monitor dying?

Good afternoon, I have a problem that started just today, and I can't seem be able to solve it on my own atm. I was using my PC as usual, when my second monitor, a BENQ GL2460HM (aprox 3-4 yo) started flickering like crazy. I didn't even touch anything special or I was playing, it simply started without apparent reason. My main monitor works just fine.

Things that I tried:
1- Roll back drivers from AMD: I have a Ryzen Vega 64, and installed a new update a few days ago. I went back to the version I had. Didn't work.
2- Checked cable: the connection is a HDMI port (monitor) to a Display Port (PC). I changed the cable to the one I have on my main monitor, and HDMI to HDMI. Still flickering.
3- Clean up the PC from dust. It was a bit messy, but not helping either.
4- Reboot PC and cutting off the electricity from the PC for a while. This one is interesting: when I let it rest for a while, it starts perfectly fine. After a few seconds after the PC starting, the monitors starts flickering, very slowly. Then, it starts to ramp up quickly until the normal high flickering. It's feels like it's very progressive.

IMPORTANT NOTE: The monitor flickers 100% of the time, UNLESS I drop the brightness levels on the monitor options, hardware itself, around the 50% mark. The more I put the brightness up to 100, the more it flickers, and more intensly.

Thank you to anyone that offers to help,

Alex

My thought is that the problem is heat/temperature related. Monitor heats up faster or hotter when the brightness is set higher - uses more power.

"Resting" cools things down. Only temporarily....

Try the BENQ monitor on another known working computer to determine if the problem stops, changes, or continues.

Key is to eliminate the problem being in the host PC or GPU.

Hey Ralston, thanks for helping me out. Done the testing, tried the monitor on another computer, and the issue persists. Same flickering, same values. Guess that confirms that is a hardware issue from the monitor itself?

That would my conclusion.

Not sure how definitive the results would be but if you can set up a small fan to circulate and/or increase air flows around the monitor then do so.,

If the monitor works longer without flickering then that would provide some verification. Lots of variables - one of which is the overall cooling effect does not really reach the component(s) in question.

No harm in trying.
