Hey, What I'm doing at the moment, is that I have this program that I need to use in XP, but this question also refers to mac osx, because it would be handy to know as well. How do you TURN the screen off, without putting it in sleep mode? the computer app requires it to be active, and so far luck, i have turned the brightness down? I basicly want to run it when I'm sleeping, but being a 24" it's lighting up my room, and have to resort of putting a cloth over it, which I dont wanna do because it'll overheat it. Any solutions? Help!!
