Laptop not identifying external Screen

[Wasp_21]

I have just got an old laptop to use temporarily while i wait to buy a media player. I don't have it in front of me now, but it has windows 7 on it. I tried using it through s-video, but nothing, and then i used the dvi/dvi cable from the laptop to the LCD. Still nothing. It doesn't register a second screen even if i ask to detect. I also used the Fn manner, but nothing. What suggestions? Thanks

Did you push the function key and a key that has a little picture of a monitor? I know that sometimes helps.

Tried it. AFAIK, Win7 should automatically detect an external monitor. From there i know how, as i had it with my previous PC with Win7. Only thing i can think, is the outputs are not working, or perhaps the onboard graphics don't allow it, but then again, it's Win7 that does all the work? Frustrating

Does it show up in windows mobility center?
