how old? the issue has been happening for over a year, I'm pretty sure I posted on here about it
I apologize, nVidia has been having driver problems for quite a while. Not a lot of people have this problem so they haven't made much effort to fix this particular bug. I know it's been an intermittent problem since the 470.xx drivers but I don't know which version will help you. If none do, the only other thing I can think of is changing the monitor cable, but since this is a known nVidia problem, it's unlikely doing that will help.
