Hey guys, so I just got the Dell P2715Q and have it connected to a late 2013 MacBook Pro 13'. The Mini DP didn't give a 4K resolution but HDMI does give the option of 4K at 30hz. The thing is that at the 3840 x 2160 resolution everything is tiny, so I'd like to set it to 2560 x 1440 but it becomes "low resolution". All the resolutions between 3840 x 2169 and 1920 x 1980 are "low resolution". 1920 is sharp but everything is too big. I'm thinking about getting a Mac Pro and wondering if I would be able to get high resolution and any res between 3840 and 1920? Or is there some sort of a work around to get the display to be sharp at 2560? Thanks guys!
