LG WebOS - Turn display on and off on display detection/undetection (usually matches HDMI connect/disconnect)

[antiobject]

Feature request

When I disconnect the HDMI cable from my MacBook while the Mac is awake, the TV stays on. It would be nice if BetterDisplay could detect the display has been removed and send a power-off command to the LG TV via the webOS controller. Perhaps a setting like "Power off on physical disconnect."

Environment

BetterDisplay v4.2.3,
Apple MacBook Pro with M1 Pro chip,
LG C2 42" connected over HDMI,
LG webOS controller: paired, connected, power control enabled
