Welcome to the forums, newcomer!

You might want to see if you have any BIOS updates pending + your OS is pending any updates.

Try and run DDU to remove all GPU drivers from your platform, then manually use the latest drivers for your GPU sourcing them from Nvidia's support site and install said driver in an elevated command, i.e, Right click installer>Run as Administrator.

Does this happen if you try the 119.98Hz option? If no, then I'd say leave it on that. The extra 24Hz won't bring much to the table.

Also are you using the cable that came with the monitor or something else? If something else, I would see about using a different cable.

In 120hz is the same. I had custume higher than 60hz(70hz 75hz 90hz etc…) in Nvidia pannel.
I have bought 2dvi cable for sure. Thanks for your help bro

I had downloaded new Nvidia driver and cleaning driver option in this. But nothing change. Thanks for your idea sir
