I disagree. It's a huge difference. The compression artifacts of an HDTV
broadcast from OTA or Comcast in Seattle are dramatic on difficult
material.
When watching Blue Ray I never seem to be distracted by the technical
aspects of the picture quality but when watching Television I'm constantly
noticing the imperfections and am constantly reminded that while it's
better
than the days of SD, it is far from perfect and we are most likely stuck
with it for a long time.

I suppose "huge" depends on the size of your TV screen.

Well, the compression artifacts are visible on my 32" bedroom LCD as on my
58" plasma. Broadcast looks great for things that don't move much but really
looks bad on difficult material like a nice shot of fall leaves on wind
blown trees or an explosion or busy screen of stuff.

I'm happy with 720p for all broadcast.

I'm on the fence about whether 1080p for BluRay (or other net/sat
feed) is a better experience. I'd always thought more pixels was
better - until we actually started to get it.

I can certainly see the difference between TV broadcast and Blu-Ray.
But it's not a huge difference.

Looking at a 720 screen, I like the image quality better from ABC that
broadcasts in 720p, compared to others that broadcast in 1080i.

On a 1080 screen, yes the 1080p image is better, but that's as much
because the source and display match, as because 1080 "is better" than
some lower number, eg 720.

Actually, after a couple of years now of watching this stuff, I am
amazed - but mostly convinced - that automagic scaling of 720p signal
to the 768 or howevermany vertical pixels, and likewise for the
horizontal from 1280 to 1366, I think it is - works remarkably well,
doesn't it? OTOH, I've seldom or never seen 720p signal on a 720 pixel
screen, maybe it shines like a mackerel in the moonlight.

Is this the reason 32" at 720p are on sale everywhere pre-Black
Friday? I'm trying to decide whether to buy one. I'm over 50, and back
in 2000, I complained about high-resolution (sic!) Pentium 3 computer
screens. The customer service rep said, "People over forty sometimes
can't adjust to the intensity of the resolution." My 19" 720p is as
clear as I need it (and I still prefer the resolution of old
machines).

On the other hand, I don't want to spend money on a television where
I'm conscious of the artifacts.

I've been watching a 32" 720p for a couple of years now, and
especially for broadcast think it's ideal. Artifacts should not be
significantly more observable on it than on a 19" - unless you're
viewing that 19" from thirty feet away! And y'know what, even then.

I was very sensitive to digital artifacts when I first got the new
set, but I don't notice them at all anymore. Now when I view an old
NTSC screen, I wonder how we ever lived with such noise!

While the market for High-Definition TV has hit the mainstream, the
industry has already started speculating about the commercialization of
Ultra-High Definition (UHD).
