DDC Save Current Settings
Save Current Settings (SCS) is a DDC command that asks a compatible monitor to save its current settings. It saves settings on the monitor, rather than preferences inside BetterDisplay.
BetterDisplay exposes Send SCS command after write as a per-display compatibility preference. It is off by default. Some monitors may need this extra command after a setting changes.
A save request alone does not confirm that the monitor accepted the original setting change. See DDC for the communication context and DDC Control for the related settings.
