Hello,

I have a 1080Ti, Ryzen 5 3600. My display is AOC G2460FQ 144hz 1080p.

First, DP doesn't work great. It only shows 640x480, and i can't modify my resolution. I tried DDU + reinstall without internet, a clear reset of my display.. And the name of my monitor isn't showing ( with hdmi, i can see the name ).

Second, with Hdmi, it's working. To set 144hz, i had to set a custom resolution and it's working. In " change resolution " in nvidia panel, i don't have 1920x1080 under " PC " but only in "Ultra HD, HD, SD ".
But in a fullscreen game : LoL, Apex, BF1, Devil may cry 5,.. all games, my Hz are stuck to 60hz ( but with higher fps ). I disabled V Sync, set Highest refresh rate in nvidia panel. It's not working.
I have to play in borderless/windowed to have 144hz, but i feel the imput lag.

Does someone can help me ?
Thanks a lot !

Have a good day.
