Connect the problem monitor.
Download this script into your
/System/Library/Displays/Overrides(note: this file is only writeable by root, so some commands require
cd /System/Library/Displays/Overrides sudo curl -O https://gist.github.com/ejdyksen/8302862/raw/patch-edid.rb
- Run the script we just downloaded (as root again). This creates a new display override plist.
sudo ruby patch-edid.rb
- Disconnect and reconnect the monitor.
