From what I understand, you're supposed to be able to get at least grayscale output from the green component jack on the back of the Apple TV if you hook it up to a composite input on a display. I would like to do this so that I don't have to run the Apple TV back out to the living room every time I want to check something when I'm hacking it. However, hooking a yellow composite video cable up to my Dell monitor's composite input doesn't give me anything -- just a black screen. Any ideas?
