[Fix] 2560x1080 Resolution With HD530 Over HDMI

[xtraa]

Natively it is not possible so here is the fix: 

 

Just in case, make a backup of your IODisplay.Framework. (The script does that, too, but you know... ) 

 

Go to Floris497, download the scripts as a .zip, follow the instructions. 

 

Then apply the CoreDisplay-patcher.command as described. Reboot. 

 

Go to display-settings, and while holding the ALT-Key, select the scaled resolutions and pick your match. 

 

Enjoy a new native resolution on your Ultrawide.   

 

Tested with Sierra 10.12.1 and 10.12.2 on Skylake.
