Mac Mini still detects monitor when it is unplugged or turned off
I have a Mac mini (2018) that continues to detect an HDMI connected monitor even after the monitor has been powered off/unplugged from power. When I unplug the HDMI cord it does remove it from my display arrangement, but this isn't helpful; I don't want to unplug my HDMI cord from my second monitor when I want to just focus on my main display.
I have already tried the "detect displays" button, deleting the profile, and have rebooted many times.
Editing to add that I don't think this is a residual power issue, as this spans multiple hours - even days - until the HDMI cord is disconnected the mac thinks the monitor is in use.
Mac mini 2018 or later
