I have a laptop connected to a projector. It can power 2 monitors. One is the laptop screen and the other the projector. When I load up the laptop, the PJ screen shows the wallpaper of my laptop without the icons, which is fine, the problem comes when I try and play a DVD through it. I've tried various players, when I press full-screen on all players I've tried, it full screens it on my laptop and nothing appears on the PJ - am I doing something silly?
