Can anyone confirm that using a Displayport or Mini Displayport connection to an external monitor provides a better image quality than with HDMI? Using HDMI, the rMB assumes it is a TV and the image quality on external monitor is horrible. Pixelated and washed out text etc. Get a headache using it. Tried to force RGB mode but no success. Can anyone confirm that use of MDP or DP provides real 2560x1440 resolution (like a Thunderbolt display) ? Thanks...!
