Hi, I've played with EasyRes, and SwitchResX, but they don't let me set the screen to use 1920*1200 in Retina mode, only standard 1x mode. Has anyone managed to do this, maybe editing a system file? The screen is so much sharper than my 2012 MBP that I like it in 1680 (1.5), but I want to try one level higher to keep the menu and toolbars from using much space.
