I fixed the issue. I just unplugged my display port cable while the setting was updating and my screen was black.

I go into display adaptor properties for the display and I set it to 144hz when I apply it it snaps straight back to 60hz afterwards

I bought a 144hz monitor in october of 2019 and when I plugged it in it was all good and allowed me to set it to 144hz. I'm not sure when but i went into the settings and it was at 60hz. Every time I try and change it back to 144 my screen turns off, t then turns on for a very short time, then turns off again and the turns back on but is still on 60hz. Please help!
