I have a cinema display hooked up to a mac pro. The screen goes completely black after 1 minute of no use. The only time it stays on is if a video is playing in full screen or if my eyeTV is on. I have obviously checked my energy settings, screen saver, rebooted, repaired permissions, etc etc. I searched around and a lot of people seem to be having this problem. Anyone know what may fix it? Its annoying when I'm trying to leave my HW on the screen and write down the answers on paper to have to move my mouse every time I want to reference the PDF. Also its a pain for reading web articles.. halp!
