Hey guys, I know this has been asked before but nothing has helped me so far. I'm running a late 2012 13" rMBP on Maverick with a 2560x1440 external display. Now I would like to get a nice 1280x720 HiDPI resolution on the external display. I already tried the trick with the terminal command, but it won't show other options in the option menu. I also installed switchresx, but selecting 720p (HiDPI) and restarting will only result in my Mac freezing at starting until I unplug the external display and creating a custom scaled resolution will also not work. The only HiDPI resolution I got to work with Switchresx is 1920x1080 which is admittedly much better for my eyes, but still not what I want. Does anybody have a resolution for my problem? Best in advance!
