If I wanted some serious screen real estate, I could hook up my powerbook via S-Video cable to my TV. It looks pretty crappy. It's an old school 32" tube. But, my friend has an HDTV with a DVI input in the back. Would this approach or equal the quality of a computer monitor because of the DVI input?? It's hard to look at the Apple Cinema Displays without comparing prices to bigger screens that serve as TVs as well...for cheaper.
