Default no 1080p on u-verse?

what's up with only 1080i being supported on at&t u-verse? i have a 1080p lcd tv and i only have the 2 choices of 720p or 1080i for my aspect ratio. what am i sacrifising by going with 1080i when i have a 1080p tv?

anybody else had this issue?

You are sacrificing nothing really unless your TV does not have a good de-interlacer and pull down processor. You did check to see that your set de-interlaces properly before you bought it, right? Does your TV support 1080p at 24fps? If not, then none of the 1080p sources will work with it anyway other than a computer or game console.

For more info see: The 1080p HDTVs

From what I can tell from the specs, that HDTV will accept a 1080p at 60 Hz (1080p/60) input as well as 1080i and 720p HD video. The 1080p/60 input would be useful for connecting a computer or game console that supports that format, but the satellite receivers and Blu-ray that support 1080p are at 24 Hz (or frames per second) so your TV could not use those signals anyway. Nobody is broadcasting 1080p/60.

So the bottom line is you won't miss not having 1080p/24 output from the U-verse box. Having said that, it is possible for them to add this in a future update for user that could use it. The bandwidth for 1080p/24 is actually less than the bandwidth required for 1080i/30, so there would be no constraints there.

Since it was not listed in the test data, I don't know. Of the Toshibas tested they all passed the de-interlacer and failed the 3:2 pull down. See the link I referenced for details and follow the links referenced.

If you don't notice any judder, I would recommend not worrying about it. If you get too educated it can spoil you forever. Just watch your TV and enjoy!

so what is the difference between de-interlacers and 3:2 pull downs?

my TV looks amazing on some HD channels, ok on others, and on some non HD channels i would like to say it looks pretty shitty. i have HDMI cables from all my media sources and some pictures are definitely less than what i expected. but i'm becoming convinced that it has alot to do with picture settings.

i will see what i can work out and respond.
thanks for all input so far...... keep it coming.

SD looks bad on a lot of HD sets. Two main reasons. Bigger screens and over compression by the providers.

When the SD is upconverted by the stations and transmitted on their HD channel it will look much better than the SD version of the channel. Some of the SD channels are just crappy. Also with U-verse the local channels are not as good as some of the other HD channels, but they are much better now than they used to be.

That is explained in detail in the link I provided. The 1080p HDTVs read that and the links it references.

I don't think any cable channel actually broadcasts in 1080p yet, so it would make no difference. The best broadcasts are currently in 1080i.

That's it, in a nutshell. We don't need to worry about 1080P yet. And something else will come along, instead of it eventuallly, making all these TV sets require replacement again!

Kinda like buying the best motherboard for your computer. All kinds of widgets and ability. It is capeable of the 'next generation CPU' or so they say.

But when you actually get to replace the CPU in it a couple years later, you find that you *still* need to get another motherboard anyway.

only Dish Network, as far as I know, is OCCASIONALLY sending a PPV movie in 1080P..

NO ONE IS SENDING SIGNALS ON A REGULAR BASIS IN 1080P!

the ONLY way to get it when you want it is via a Blu Ray player...

Its a shame that the TV sales people are misleading so many people on this issue..

I tried 2 different sets of tv's that were 1080p using ATT UVERSE.
in both cases when i put the sets in 1080i aspect ratio, the words
that appear on the RECORDED panel in the DVR disappear on the left side of the screen.
any suggestions?

My panny plasma will do that if it is not formatted to "full" so maybe your set is zoomed somehow.
