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?
Kind regards
Tim

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.
 
Hi
Thanks for the quick response, even if it wasn't the answer I wanted!
Much appreciated
Kind regards

Put a note on the notebook that tells tells them to "Restart windows if
you forget to turn on the projector".
 
On my D510 there is a "FN" key on the lower left that while holding down I
push "F8" which switches (forces) the Video outputs. A few times of this will
generally get you the results you are after.
