Laptop when extended for use on a projector have a reddish tint

Original title: Portable, extended desktop reddish?

We use a computer laptop w/vista for several months, this Sunday when we connected, when the post office came on the projector, it was reddish (almost looked hidden), you could see the picture and everything, but with a strong tint reddish. I tried to post the same on both, but with the same result. The laptop screen is fine, I tried to reproduce the screen with no luck. I tried to change the resolution on the desktop extended with no luck, just change the appearance. We use powerpoint, but no matter what slide us looks the same. The dvd works well on the projector, and when he starts the colors are ok. I'll try a 2nd laptop on it this afternoon, but I don't think this is the projector. I think that a parameter has probably changed. Any help would be appreciated. Thanks, Bruce

Hello

Found the problem after a few game. Pins of the connector on the projector, a few of them seems to be done back up a bit. If you slightly turn it works.

Thank you. Bruce
