How to check if System Integrity Protection is enabled or disabled If you later want to start using SIP once again (and you really should), then follow these steps again, except this time you'll enter csrutil enable in the Terminal instead.

SwitchResX has always worked flawlessly and reliably when installed on Mac OS Yosemite and it has many features the other apps used adjusting display resolutions simply dont have. I found bigger makes it slightly blurry so go with smaller-I chose "2046x1536". To use these display resolutions requires the usage of an application called 'SwitchResX' or similar type of app. It must be 2 pixels bigger or smaller than the native resolution in one direction (this is the OS X quirk). Now add a Custom Resolution that is "scaled". Follow the instructions from SwitchResX creator. If you're on El Capitan or later you need to disable System Integrity Protection (temporarily) to add a custom resolution for Packed Pixels.

If one have osx El Capitan, must first desactivate SIP ein order to create the custom resolutiom file.
#Switchresx el capitan 1080p#
If you are happy with any of the ones that do work then stop here, else continue. Using switchresX, os X can display resolutions bigger than 1080p through HDMI and DVI cables. However not all of the HiDPI resolutions work due to an OS X bug. You can play with the resolutions for the Packed Pixels which is probably listed as Color LCD (2). This can be changed using the 3rd party app (non-free) SwitchResX. On OS X the Packed Pixels display won't automatically show up as "Retina" or "HiDPI" resolution, instead the OS will use the full resolution of the display making everything tiny.
