    Hey guys,

    Have a question about the TV I'm thinking about purchasing. It's between the Toshiba 57H82 and 50H82. Now the 57" says it has 720p for vertical scanning lines (native) and the 50" has 1080i.

    What does this all mean? Since both are HDTV ready, shoudn't both be capable of 1080i? If so, then why doesn't the 57" mention it?

    Can anybody help clarify where both these TV's differ?

    Greetings

    Toshiba upscales 720P to 1080i. It will not show it native.

    Regards

    Hmmm,

    So when it comes down to it, will I be able to get a true 1080i out of the 57"? Am I missing something if I don't get 1080i native?

    Thanks Michael

    He meant that the Toshiba's will not display 720p natively, but will upconvert to 1080i. They do display 1080i natively though.

    AFAIK, none of the current RPTVs display 720p natively.

    Well, why does the Toshiba 57H82 claim to display 720p natively?

    Sorry for my ignorance and confusion, but thanks for the replys! I'm so close to making the purchase, I just need to understand what exactly I'm getting into.

    Where does that TV claim 720p native support?

    BestBuy.com is simply wrong. The site is not the most accurate place for info. I prefer OneCall.com although even they are not always accurate or complete.

    Okay, well everywhere I've read tells me the same thing, but besides that, is there much of a difference from having 1080i upconverted from 720p to it being displayed natively?

    Thanks

    It does state that it has 720 capability, but it doesn't state that it can display 720p natively. Maybe it means it can accept 720p whereas the older models didn't.

    Yeah, their info can be misleading. However, if you check their "glossary", they explain that their IDSC Pro technology displays 720p in 1080i.

    Here's a quote from the link:

    http://www.toshiba.com/tacp/tv/glossary_tv.html#I

    "IDSC Pro passes through 1080i images without alteration, and now accepts 720p images and displays them as 1080i."

    Okay,

    I hate to beat this thing to death, I really do, but since both the larger (65") and smaller (50") offer 1080i natively, what (if anything) am I missing out on. I'm really in the dark on whether the 720p up-conversion to 1080i is any better or worse than the TV being 1080i natively. I've tried searches, but haven't come up with anything. Please help!

    Chris,

    All 3 models (65H82, 57H82 and 50H82) should be the same as far as 720p and 1080i capability goes. They all upconvert 720p to 1080i and display 1080i natively. The fact that they provide the upconversion, instead of not at all, is a good thing. At worst, it's a non-issue if their upconversion quality is inferior to whatever HD STB you use. Most STBs will offer this upconversion as well since extremely few HDTVs handle 720p natively--at least in the forseeable future.

    However, since you're concerned about that issue, but have not mentioned the 480i/p issue, did you also know that those TVs also upconvert 480i/p to 540p? THAT is the native-vs-upconversion issue that most people are concerned with although most Toshiba owners (and there are tons of them) love their Toshiba's anyhow.

    Check here for a good article (by Michael above) on the Toshiba's 480i/p->540p upconversion:

    http://www.keohi.com/keohihdtv/brand...jul02_pg1.html

    In the end, you really should see and compare w/ other TVs that don't upconvert for yourself.

    (You folks do realize my link was to show how Toshiba's marketing confuses potential customers, right? [​IMG] )

    Okay, it seems I was making more out of the situation than I actually should have. Thanks a BUNCH Man-Fai, and the rest! I think I know what I'm going to go with now. Much appreciated!

    Christopher, take a look at this thread. It might give you some insight toward understanding 720p/180i

    Ha ha. That thread might confuse the heck out of him--at least initially. [​IMG]

    Anyway, that thread is about native 720p and 1080i and about how nearly all current HDTVs cannot meet the full potential of full 1080i resolution. And also about how we need to push the TV makers to strive for the ultimate goal.

    Nevertheless, current HDTVs w/ current HD sources do look awesome. [​IMG] Can hardly imagine what full 1080p (source AND display) will look like years from now...

    I believe greg_t is right. At one point, Toshiba sets couldn't do anything with a 720p signal. Now they can accept the signal, upconvert it to 1080i and display an image.

    All of their HD-ready sets do 1080i natively.
