Newer drivers are very buggy I have the dreaded black screen bug which makes the entire display go black & you have to hard reset to get it back. Thought it was the monitor going but turns out its the newer drivers lot of people on Nvidia forums have the same issue on GTX10XX series cards especially! Looks like Nvidia broke something fundamental & have not worked out how to fix yet.
Thanks, I'll probably uninstall and try the previous driver again as that worked fine for me.
Nope, you on Multi Screens?
No, just the one.
