UltraVNC is able to blank the monitor of the computer being remotely accessed. My question is, how is this possible?
In my understanding, due to the nature of the Windows OS, remote desktop applications are limited to remotely displaying only snapshots of the current physical screen. I believe UltraVNC is also subject to this limitation. But, somehow, they have found a way to disconnect the physical screen whilst remotely displaying what it should normally display.
Any idea how this is done?
