I don't think you're right about that. There were sets that did 1920x1080 at 1080i before 1080p was available. Otherwise, they didn't display 1080i. It's by definition--even if the lines are scanned in 2 separate waves (i), it's still 1080 lines. Which is 1920x1080.

Sure there are sets that display a 1080i signal-but they're downscaling. So it's not showing 1080i.

Here's an example.

Not made anymore, but maxed out at 1080i, had 1920x1080 pixels.



That sharp was touted as a 1080P TV not 1080i, see here: http://www.i4u.com/article5121.html

The CRTRP TV's were often 540P, 1080i. I think this is because there is not a definitive pixel structure like microdisplay screens. The CRT is just one big tube being bombarded by phosphors to create the picture.

Bottom line is both a 720P set and a 1080P set are considered HDTV and are considerably better than watching a 480P DVD on your old direct view CRT.

I went 1080P projection, because it was only $200 more than the same TV in 720P, so why not. Both a 768 plasma or 1080P(provided it does 1080 as per the article)LCD or RPTV are great pictures. You may notice I am not a DLP fan as most create 1080P via "wobulation"
