Hallo. I just won a Dell Ultrasharp 1800FP and I have a few problems. I have connected it so it works as a secundary screen (extended desctop)

1. If I watch a movie or don't move the curser in a few minutes it goes in to Power Saving Mode.. Is there any ways I can disable or increase the powers saving mode?

2. I cant run a fullscreen program (for example movie in fullscreen) in one of my two screens and do something else on the other one. Is there anyway I can make it work?
