I was thinking about buying a nice monitor and wanted to know if it was possible to use it as a TV Screen. I don't need to connect cable to it, I am more wondering about my xbox 360. Basically I want to know if something exists that can serve as both a computer monitor and something to play my xbox on. Thanks. Also completely unrelated but is the Powerbook G4 15" and the Macbook Pro 15" the same dimensions ?
