Disabled monitor will either turn on again immediately (while still showing as disabled in DisableMonitor) or the disabled monitor will show a black screen, sometimes even a frozen cursor, instead of turning off.

It will at all time remain visible in the display preferences and also continue to consume GPU processing power.
