Recently unable to switch from 60Hz to 144Hz

[Golem74]

Hello everyone,

I need your advice to solve a problem that appeared yesterday.

My screen is the BenQ ZOWIE XL2411P TN 144Hz 24 Inch, and my GPU is an Nvidia RTX 2080 Super.
I use a Display Port cable between the 2, which until yesterday allowed me to use the monitor normally in its 144Hz configuration. But since yesterday, following a screen sleep, impossible to select this option, the screen remains blocked in 60Hz.

I tried from the Nvidia control panel to make sure I was in “PC” resolution and not “Ultra HD, HD, SD” (which is the native selection), if I try to apply 144Hz, the screen turns off and no signal is detected. I have to restart the PC and force a low resolution boot.

Finally, if the screen goes to sleep, the same problem occurs and I have to restart
Just so you know, I disconnected and reconnected my cable and updated my GPU drivers.

I have no solution and even if I can use my PC at 60Hz, it was not the initial idea when I bought it 2 years ago.

Thanks

Hello

Do you still need assistance?

Hi,

I do indeed, in the meantime I tried several things, like changing the Display Port cable as well as completely reinstall my GPU drivers.

Thanks

did you use DDU to remove then reinstall your drivers?
have you tried another monitor?
