Hi when i m trying to use my 165hz Hdr monitor somtimes his stuck to 120hz and no HDR via Nvidia Control panel
i updated that all the gpu drivers from nvidia the OS The BIOS alsoUpdate your post to include full system hardware specs and OS information.
The posted image is non-English and also appears to be a mirror image of the Nvidia Control panel. Not sure if that is language related....
I suggest manually downloading the applicable video drivers directly from the manufacturer's website.
Reinstall and reconfigure.
No third party tools or installers.
