I've tried Active DP to DVI-D and Passive DP to DVI-D. On active I get a max res of 1600x1200, on passive I get max res of 1920x1080p. On the active adapter it shows up as "unknown" instead of "dual-dvi" like the other two in the screen resolution settings. On the passive adapter it shows up as "Digital". Could the active adapter be bad? I thought the R9s did not need active adapters?
The two monitors cabled with DVI-DVI work fine. Any thoughts?
