Can't enable disabled monitor #2

Open Cynary opened 4 months ago

Cynary commented 4 months ago

If a monitor is disabled when I run GetAllPotentialDisplays, I have no way to enable it. But if I use an earlier returned value, it works. Here's an easy repro:

# display 0 is enabled
$displays = WindowsDisplayManager\GetAllPotentialDisplays
$displays[0].disable() # Returns True, display 0 is disabled now.
$displays[0].enable() # Returns True, display 0 is enabled now.
$displays[0].disable() # Returns True, display 0 is disabled now.
$displays = WindowsDisplayManager\GetAllPotentialDisplays # display 0 now has no target.
$displays[0].enable() # Returns True, but nothing happens.

Output with display 0 enabled:
