After some advice on an issue plaguing my church.
We upgraded the main projection system from VGA to HDMI, all good.
However, when we have to switch the projector input to VGA, the windows computer attached disables its output upsetting the projection software/rear projector.
We're needing a way to stop windows disabling its output. My idea was a HDMI splitter to give the computer a constant 'destination' device but have not got one to try yet.
Many thanks :)
