My friend just got a RTX 2060 which doesn't have a DVI-D connection to his monitor which is needed for 120hz. I ordered a DP to DVI-D cable adapter but its still not letting him select 120hz. Any ideas?
Yep you'll need an active adapter like this one https://www.amazon.co.uk/StarTech-com-DisplayPort-DVI-Adapter-1920x1200-Black/dp/B004SUO1GM Not too expensive in the grand scheme of things
