I have a 27 Asus monitor that is the only display for the mini. Thus the MacBook gets most of the use and the Mini not so much. The Mac mini is a security machine in case my MacBook Pro gets stolen again like one did years ago.
#MACBOOK PRO 4K 60HZ DISABLE SIP SWITCHRESX PC#
For 2014 and beyond, though, 4K is the new aspirational resolution for every hardcore PC gamer. I have two Macintosh computers, 1) MacBook and 2) Mac mini (Late 2012). If I don't do the 1440 twice, the problem changes to: now is the external monitor black in desktop mode. Is 2560×1600 a 4K Many enthusiasts today run 27-inch or 30-inch monitors at much higher resolutions of 2560×1440 or 2560×1600, respectively. I got it Smooth 60hz with my Macbook and the Philips TV.
So I finally found out that I got to set external to 1440x900 !non hidpi, close the lid, the screen doesn't turn black, now same to do again, than back to the new HiDPI and voila I can open and close the lid like expected even after sleep but not after reboot. Until I close the lid to clamshell mode, then the Dell went black (not inactive, but by a streamer like splashtop you can see there is no more monitor recognized by the system) I also think I read that this is not a fine (1to4?) pixel scaling which is more difficult to handle for developers, maybe causing blurry so imperfection is not wanted.īut switchresx can easily add a scaled 3840x2160 (1920x1080hidpi) which works fine on Dell u2515h hdmi and miniDP-DP at MBproEarly2013Retina I don't understand how everything comes together but after a few weeks intense search I found out that a 1920x1080hidpi is marked as "not usable for the desktop".
