I'm afraid I don't understand the difference between LCD computer screens and TV screens. For example, a 15" LCD computer screen goes for about $400 (CAN) whereas a 13" LCD TV screen goes for two grand. Could someone please tell me the difference. Thank you. Also, you can now play DVDs on your computer screen. DVDs play 480i, but computer monitors are non-interlaced. Does it play this way on a monitor, and does it look as good as a DVD playing on a LCD TV? Thanks again.
