# Toggle between high and low resolutions, or set specific resolution and refresh rate. | |
# Adapted this to be easily used by Sunshine stream thing. | |
# | |
# Example Sunshine "Do Command" for changing resolution: | |
# powershell.exe -File "C:\Apps\Scripts\toggle-resolution.ps1" -Width 1920 -Height 1080 -Freq 60 | |
# And the "Undo Command": | |
# powershell.exe -File "C:\Apps\Scripts\toggle-resolution.ps1" -Width 3440 -Height 1440 -Freq 144 | |
# And for a shortcut that just toggles between high and low resolutions (set the values below): | |
# powershell.exe -File "C:\Apps\Scripts\toggle-resolution.ps1" | |
