Toggle NVIDIA Surround and Load the Appropriate Monitor Profile
Return to DisplayFusion Scripted Functions (Macros)

Description
This script will toggle NVIDIA Surround mode, and then load the appropriate Monitor Profile, because when toggling Surround off, usually only one monitor ends up enabled. Before running this script, you need to save DisplayFusion Monitor Profiles for when Surround is enabled, and also when it's disabled, then update the names in the script to match the names of your Monitor Profiles. You also need to make sure to enable the Ctrl + Alt + S hotkey for toggling Surround in the NVIDIA Control Panel.
