I understand (I think), the technical difference between HDTV Monitor and the one with the tuner built in. The $$$ difference between these two are between 250 to 500 USD. My local cable( TWarner)says, that they will give a free upgrade of HD Box and replace my Digital Cable Box. If that is the case, can I just buy a HDTV Monitor and have my HD cable box decode the HD Transmission for my monitor? Do I lose anything else by not buying a tuner built-in TV? If I can afford the extra bucks, do you people recommend to go for the one with built-in Tuner?
