There are differences in how well hi-def monitors display non-hi-def content.
It is not merely a question of stretching the image to the wider format. I read
many reviews of hd sets before I bought mine and the reviewer frequently would
comment on how some sets were better at displaying non-hi-def content than
Our local BestBuy has an interesting demo set up. There are a couple of
toy cars and figures on a small turntable rotating in front of two Sony
camcorders, one SD and one HD. Their video outputs are fed to a Sony
HDTV via a selector that lets the viewer select either camcorder.
You're supposed to switch between them and see how much better the HD
image looks, so you'll buy a HD camcorder instead of an SD one (or to
replace your existing SD one).
However, the SD image looks really really awful, not just lower
resolution than the HD one, but with all sorts of upsampling
artifacts. It looks much worse than a normal SD TV set displaying SD
video. What the demo *really* shows is how badly the Sony HDTV handles
upsampling the SD content. It shouts to me "don't buy this Sony TV
set". Unfortunately, that's probably not the message that most people
will get - they'll think the TV is fine and SD is just naturally far
inferior to HD.

I was in the consumer electronics field for many years. It was VERY common for
retail outlets to disconnect the tweeters in speakers that they didn't want you
I wouldn't bet that you could make ANY accurate decisions based upon a store
demo. It was very likely rigged.
And TV isn't the right word here either, DVRs and DVD recorders have
the same requirements (regarding tuners).
And what about all that non-HDTV ATSC broadcast? And DVDs too (they're
not HD, and not NTSC)?
