I have the Dell 8930 and a Dell P2715 4K Monitor. Will I get a better resolution quality using the Mini DP and HDMI connection vs. the HDMI to HDMI connection?
If we are talking the almost new Dell, then HDMI should be better; older versions of HDMI couldnt handle 4K very well (or at all), so DP was better, but with HDMI2, it has the bandwidth.
