I have a 2070 rtx, i7 6700k, z270-A PRO and a 650 watt PSU and i cannot get my display port to work. Im currently using a HDMI cord which only outputs 60 htz, which is disgusting compared to my original 144. Recently changed the GPU, PSU, and MOBO. Also added 16 more gigs of ram, everything is updated including my drivers for the monitor. I just cannot see to find the reason why my display port wont work. Also just bought a brand new one thinking it was the cable itself.
