I am having problems with my IBM T43 laptop and any projector I connect to it via a VGA cable. I can have dual screen so they both are showing the same. If I play a DVD or windows media player 10. The laptop plays it fine, the projector shows Win DVD or media player but the screen does not display the film. If I use powerpoint no problem it displays on both screens.
I am using Windows XP Pro.
Have looked on MS site and tried a couple of things, eg making sure the resolution on Primary and Secondary displays are the same. But no joy.
I can toggle between each one and have tried the desktop drag etc on the secondary one, but it makes my life a lot easier (as a trainer) if I was able to have both at the same time.
