Video playback problem - laptop car pc
So I have my laptop connected up to an external screen via vga and 'clone' settings on the laptop graphics card so that everything is exactly the same on the car pc screen.
However, when playing any form of video through roadrunner, mediaengine or even windows media player, the video plays, BUT it only shows on the laptop i.e. the video seems to be playing on the external screen but nothing is appearing.
Now this seems a bit odd to me - why is it only playing back on one screen when its supposed to be a clone monitor ?
