I think you better read the specs again.
It doesn't have a built in HDTV tuner! You can view HDTV on any pc monitor ( they are capable unlike regular TV'S, ) you would get the clarity but not the widescreen view, that's where the widescreen TV's and widescreen monitors come into play.
A regular T.V is 4.3 ratio (not widescreen) and it's not capable of doing 1080i which is real HDTV.
Even if that lcd had a built in tuner why would you buy it? You want a wide screen 16.9 to view the entire picture.That lcd is only 4.3 like a regular TV.
I have a "hi-pix " card in my pc which decodes the OTA hdtv ( in NYC, only get channel 2 and 5 now due to sept 11, other stations were on the WTC) signals and watch on my PC or send signal to my MITS65908 widescreen HDTV.
HDTV signals travel over the UHF band, regular travels over the VHF band. You will see the same program ,but the UHF is the HDTV signal.
