I am using a notebook to drive a projector at my local church using a
couple
of dual monitor programs OpenSong and PowerPoint.
The problem is that the projector is not always on when the notebook
starts
up and, just to confuse matters further, there is a switchbox so the
preacher
at the front can also use the projector.
As I am not always operating the notebook and the other users are less
confident technically I need a way to force Windows to enable the second
monitor regardless of whether Windows thinks it is connected.
Does anyone know if this is possible?
It is not possible. Graphics cards determine the availability of a display
device by detecting its terminating impedance. If the display isn't
connected, the termination is missing and the graphics card assumes
(correctly) that there is no display.
