Summary:
I bough new monitor DEL UP2716D with 2560x1440 resolution.
This monitor has a handy feature allowing to display inputs from two different sources at the same time.
Basically screen is divided in halves (1280x1440 each). One half for one input.
So I wanted to configure OS X with this unusual display resolution... Here is what I had to do.

Steps to Reproduce:
1. Purchase 3rd party tool SwitchResX
2. Disable System Integrity Protection so SwitchResX can save custom configuration in /System/Library/Displays
3. Let SwitchResX to add "* /System/Library/Displays" to /System/Library/Sandbox/rootless.conf
4. Enable System Integrity Protection

Expected Results:
OS X should provide a way to achive this withou using 3rd party tools and modify SIP.

Actual Results:
A bit hacky solution.

Version:
10.11.6

Notes:


Configuration:
MBA 5,2 13' + DELL UP2716D 27'
