I have a Sharp Aquos 26" which I believe is HDTV? I sometimes use that
as a PC monitor and it has a super resolution.
Sometimes I download HDTV recordings of TV shows and they look fantastic
on the Aquos, whereas the cable TV leaves a lot to be desired. .
Before I got my other monitors, this was my only PC monitor. I sat on
the floor when I used it. This was the big problem. You usually sit in a
different way when you use a TV to when you use a PC. So you have to
decide which of the two to optimise the TVs position for. Mine was
optimised for TV viewing which was why it was invonvenient. However at
the time I hardly used the PC at all at home because I was so sick of it
after a whole day at work in front of one!
Some of these high end tv monitors have a number of different input
channels, for example mine has Analogue and Digital TV, 2! DVD, VCR and PC.
I had a party a while back and put on some music with a really cool
psychedelic screensaver on the PC. All my (non-techy) friends thought
that was really cool.
You'll have no trouble using your HDTV as a monitor - ideally check the
manual before you buy it to confirm that it has PC DVI or VGA in.
