[SOLVED] 144hz monitor no longer able to do 144hz refresh

[Pitts16]

Hi all

I have an AOC (27G2G4) Monitor. It performed fine for the last year but recently it has an issue displaying at 144hz. the bottom inch of the screen completely distorts all the way across (horizontally). If I lower the refresh rate to 120hz it seems to perform fine. I'm unsure what is going and am wondering if I there is a fix for this or if my monitor is just on it's way out. I've disabled the adaptive sync features, done a clean graphics driver install, I've certainly rebooted a few times. I'm sure there are additional things I can do that I've missed. Any help would be greatly appreciated.

specs
Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz 4.20 GHz
Evga gtx 1060 6gb edition
Gigabyte Z27OP-D3-CF
AOC (27G2G4) Monitor (connected with DP)
Benq GW2760 (connected with HDMI)

Thanks

try a different display and see if the same type of distortion appears at higher refresh rates.
if so, than it's not the monitor.

you can also try searching for updated monitor firmware and AOC drivers.
updating either or both could help.
