I recently upgraded from a comp that has a 1080 to a 2080 and the 2080 doesn't have a DVI input. So I'm using the Display Port cable that came w/my BenQ 120hz monitor thinking it'd be fine and I can't select more than 60hz anymore. I've tried uninstalling and reinstalling the drivers of both the video card and monitor, nothing. Idk what to do D:
