[SOLVED] Guys pls help me

[Ghostonee]

I have a 144hz monitor, and it has always worked well, but for a few weeks a black bar started to appears at the bottom of the monitor that has some shaky pixels but this only happens when I use 144hz, now, I have always used my monitor at this frequency without any sort of problems, i dont understand why now he gives me this problem, can someone help me?
I tried everything, changed the hdmi cable to a display port, even resetting my windows to factory conditions but nothing, continues to have this problem, I repeat only at 144hz
pls help

looks like a common fault - link

I would contact AOC for warranty if its still covered.
