Since moving, I now have access to a second, 17" Sharp TFT screen when at home. I was very surprised/pleased on Sunday as when working I plugged it in to the Powerbook to see two full, separate screens (both showing Vader and his iPod). Really helped speed things along on my llayout and design project. Anyway, brought the 'book into work this morning to finish said project and nicked the screen from my Desktop G5. The question is, is there a way to utilise my Powerbook screen as a second screen on the G5? It doesn't seem right nicking the big computer's screen to work with the little one? Surely I can make it work the other way round? Is this possible at all?
