Weird display problem

[Ozzieh_man]

Hi, yetserday i started to notice some flickering going on once in a while in the top portion of my AOC g24G1 after installing a new GPU. I have a dual monitor setup and the other monitor isn't flickering, so I narrowed it down to either the Display Port connection on the monitor being broken, the display port cable being broken or the monitor being broken. Are there any suggestion as to how i need to further investigate this?

Try a different cable.

Okay i did that and with another cable (HDMI) instead of DP, it still shows this flicker. I tried another monitor from the trash pile and it doesn't show any flickering. Is it safe to say this monitor is faulty?

Sounds like it's the monitor itself,but does it work fine with other PCs?

Yeah it does, I think i found the problem though. I read an old EVGA forum post that states that 144hz LCD monitors tend to flicker when the GPU downclocks too much in "power saving mode". I fixed this by setting the powerplan to "prefer optimal performance", and what do you know... no flickering anymore.
