I don't see any loss of quality on my Sony KV32HS510. The HD picture is
stunning at 1080i, which is native for this tube. Monday nights ESPN HD
Packers/Seahawks game was fabulous in HD. Just too bad the Packers lost :-(

I am sure its stunning, no doubt. That seems to be a good word for
describing HD. Stunning. When I had just gotten my TV and Voom I knew the
HD stations were nice, but it took me a bit to really see it. I would be
watching a movie and sooner or later it would hit me, wow. Especially the
documentary style programs and RUSH commercials, and of course Discovery HD.
I love it when the networks really show off HD, thats how it all should be.

How can 1080i be a native 4:3 tube resolution? 1080i is a 16:9 format. Or
maybe I am thinking of "native" wrong. Does native simply mean that the set
is capable of displaying 1080i without any conversion of any kind? Even if
it has black bars on top and bottom?

If the 4:3 tube set displays 1080i unmodified, with black bars of course,
than it must be capable of 1920x1440 (which is 4:3, and not something you
ever see). Does that sound correct?

Thanks for helping me understand these things more clearly.

My Sony TV is a 4:3 tube. 32 inch size. It is HD capable. Most stuff I watch
is in the 4:3 format. I have Dishnetwork and an Over the Air antenna. I get
my locals off (including digital) from the antenna. My Dishnetwork
includes their HD channels. I simply change the format through the
Dishnetwork model 811 set top box to match what my Sony can display. If it
is in a 4:3 format , I choose that. If it is in a HDTV 16:3 format...I
choose that. I get black bars top/bottom on the 16:3 and full screen on the
4:3. This make sense to you my friend?

Native resolution is something used to describe LCD monitors. But I supose
you could also use it to describe scan converting. So a standard 480i 4:3
TV NTSC signal scan converted for display on an HDTV would not be "native".
However, 4:3 HDTVs don't need to scan convert a 1080i signal. They can
display it natively so to speak. It simply "draws" the scan lines so that
they only use a 16:9 portion of the screen.

The choice to buy a 4:3 TV has more to do with what the majority of your
viewing material is. If you watch a lot of 4:3 material, you can probably
get a better combination of 16:9 and 4:3 viewing area for a particular
budget with a 4:3 set. However, the amount of 4:3 sets vs. 16:9 seems to be
dwindling so this may not hold true as much now as it did when I bought my
4:3 set 1 1/2 years ago.
