Question every time I set my monitor to 165hz I got purple lines

[A-Way]

I recently updated a bunch of drivers on my PC. After all that my monitor fps was capped at 120fps. So I restarted my computer and it let me change fps beyond 120. I tried changing it to 165 and I got a visual error on my monitor. 144hz works but I get the purple lines when I change it to 165. https://ibb.co/cXbC4bB

Hey there,

Which model Omen display do you have?

Either the monitor isn't rated for such a speed, or your monitor cable cannot handle it, would be my guesses.

Is G-sync activated when this happens?

No, I just checked the Nvidia control panel and it says it's not on.

I rolled back by graphic cards driver and it fixed it.
