There are many TVs that support 480i/p, 720p, and 1080i. Toshiba's ***82 line is one example. Someone can correct me if I'm wrong but I think the only TV that supports 1080p is the 57 inch Toshiba LCOS:

And at $9k MSRP it doesn't come cheap.

Actually most of the TVs will not display both 720p AND 1080I. Most will do one OR the other but not both. Most do 1080i and 480p. Everything is up or down converted to the displays native res.

The Panny RPTVs have supported 720p native on 2 model runs, and now again do not. They say it takes much finer electronics to support 720p native at 45KHz than it does to downconvert incoming 720p to 1080i, at 33KHz. Therefore displaying 720p native is more expensive and they have chosen not to do it anymore. At least that was the word at CES in January.

Many of the fixed pixel devices like plasmas and DLPs support 720p native, because their chips/pixel structure are set up that way.

But I don't know of any CRT based RPTVs at this time that support 720p native. They all downconvert it to 1080i.

Which means they can say they "handle" 720p, or "are compatible with" 720p, which they do, and are. They simply do not display it in its native format. They "handle" it by taking it in and downconverting it, but they don't put it out.

I saw the 1080p LCOS at CES, and it was a wonder to behold. It is the only fixed pixel image I could sit as close to as I sit from my own CRT based RPTV, and still be happy, free of screendoor effect. There were 2 of them, and they were displaying 1080p DVD, which Toshiba also had, coming from a couple of proprietary prototype DVD players, one red laser and one blue laser. It was magnificent!

If you want to see a native CRT 720p capable image, click on my website, below. The image is a 1080i CBS image, but the electronics that display it are 45KHz capable.
