macOS High Sierra (10.13.6) + 1080ti and 4k at 120hz


For some reason I can’t see any options to run my brand new Asus XG438Q at 4k above 60hz under High Sierra. It runs flawlessly under Win10 at 120hz. Is this problem tied with nvidia web driver or monitor support?
Is it even possible to run 4k more than 60hz with latest High Sierra web drivers? I haven’t tried with any AMD card yet.


This should be possible. My friend is running two 4k@60Hz displays at the same time. What cable are you using?
