LCD Screen: video plays on desktop but appearing black on big screen...

[Heyjoojoo]

I have a desktop PC (Windows XP Pro, Nvidia graphics 2Gigs SDRAM, etc) that is connected to an LCD projector. The projector projects the image from the PC onto a large screen. The PC's desktop shows up on the big screen with no problem. From time to time, I like to show wmv and avi videos and play them for everyone else to see on the big screen. When I play the videos on the PC, they show up on the PC's monitor but only show as black on the big screen. I don't know why this happens. The desktop shows up on the big screen with no problem but any wmv or avi videos do not. Is it the player? Screen resolution?

That's usually caused by incorrect overlay settings. Go to 'Control Panel>Display Settings>Advanced>Troubleshoot' and move the slider for 'Hardware Acceleration' down to about 1/4 and see if that corrects the problem.

If you look to the manual for your video card, you should see information there for further settings. Some video player software like VLC or others also have overlay settings adjustments.

Hurray. It worked! Thanks for the help.
