I would start by looking in the manual for the *TV* - the video *source* is often irrelevant.
Most of the modern British television sets that I knew of even before moving to the USA (10½ years ago) played NTSC signals with no problem - and with the leap into digital, HD and LCD/plasma you will probably find that not only will it have NTSC capabilities, but it may also have a specific (VGA?) computer connection as one of its selectable inputs.
