1080i and 720P will be available on the same set...
on SD (standard definition) channels, these shows are gonna all look like crap (even if the tv is 1080p)... these HD TVs only produce good looking pictures if the shows/movies are shown in HD. so if ur expecting ur favorite episode of MASH, simpsons, The Price Is Right to look good you're gonna be hating life, until they're filmed and broadcast in the HD format.
DIGITAL channels does NOT mean HD (high definition)... if you want HD, then the program/station needs to state HD!! so careful with marketing terms.
the HD channels are usually in the high range... my for example, on Verizon FiOS, are in the 500-699 range.
the other channels are SD (standard definition) channels... so they will look blurred/blockish
the big box stores, don't do anybody any favores by playing content ONLY in HD movies in their store... if they showed you a SD/regular broadcast show, you'd see that these HD TVs don't display such a nice picture as compared to the REGULAR TVs..... that is why when these HDTVs came out a few yrs ago, so MANY were returned, because people expected the picture at home to look as nice as it did at the store.
now your DVD player will show a nice picture, but your VHS player or VHC-C camera will look like crap!
im a little confused, doc. i wonder if the hdtv's youve been using have poor video rendering because SD signals should still look a bit better on a high def tv as opposed to an old crt.
what i think you mean is SD format is brought into a crt tv and displayed at one resolution, and one only. it doesnt get stretched, skewed or garbled.... but on an hdtv youre taking that small little video window and stretching it out and bledning in lots more pixels, which is why older hdtv's looked pretty bad with SD signals.
but, anymore most hdtv's have great video processing and they will upconvert SD signals into a sort of hybrid-hd result... nothing near as good as real hd but the picture is better then on a crt tv (especially the color).
the above can also be a reason to buy brand-name sets. usually, the ones like samsungs and lg's have much better video processing then off-brand stuff... not to mention the sets overall are usually more durable. there are good cheap brands though... vizio comes to mind....
Speaking of Vizio, I just bought a 22" for the bedroom and it looks great.
I even found 7 HD channels on the high end being broadcast without encryption, so I can get them HD without having the Comcast HD box. Sweet.
Overall the set is perfect for the bedroom setup. Picture is sharp, deep blacks, rich color. My only complaint would be the very basic remote that comes with it. Good buy for less than $300 though. I highly recommend it.
i still think the SD channels look much better on the old CRTs! i have a 3 HDTV sets: LG, Phillips and Hitachi. the pictures on SD channels, IMHO, don't look nearly as well as they did on my old 27" sony CRT....
when u look at HD programming most of the time, and then tune DOWN to SD programming.... HUGH differences in picture quality, which i'm certain nobody disagrees with.... but the SD channels are stretched out, pixelated and washed out.
i can't wait til most programming is done in HD format.... it would be real nice if the damm cable,satilite and fiber companies didn't charge EXTRA for the stupid HD box we need.
