They are idiots, so let me say this in big bold print, as far as movies are concerned THERE IS NO DIFFERENCE BETWEEN 1080i AND 1080p. See, I did it in caps too, so it must be true. Let me explain (if your eyes glaze over, the short version is at the end).
For clarification, let me start by saying that there are essentially no 1080i TVs anymore. Unless you bought a CRT based TV, every modern TV is progressive scan (as in LCD, Plasma, LCOS, DLP). They are incapable of displaying a 1080i signal as 1080i. So what we’re talking about here mostly applies to people with 1080p native displays.
this is going to be technical, but i have to respond here.
i've seen that article. that's not correct. the guy who wrote that doesnt seem to grasp technology properly.
how do i know? easy:
take a laptop.
hook up it up to a "1080i" lcd/plasma. your resolution = 1366 x 768.
hook up it up to a 1080p lcd/plasma. your resolution = 1920 x 1080.
thats exactly 1,024,512 pixels missing on the "1080i" set. that's it. end of argument right there. that's is the difference in the units. 1080p tv has more resolution than "720p".
read on for more detailed explaination and correction of the guys article.
yes, that article is correct when it says there are no XXXXi
true, they dont display interlaced picture anymore... BUT big deal, the 720p doesnt magically add 312 lines of horizontal resolution to become 1080p. it just takes 1080i signals, deinterlaces the image and displays it within it's maximum resolution which is 1366 x 768.
the notion that deinterlacing a 1080i signal into 1080p will give you the same resolution as 1080p direct into 1080p is wrong. deinterlacing involves the tv having to process an image and generate the missing lines before it hits your eyes. the better your tv (pioneer, sony, samsung, panny..) the better the deinterlacing chipset, the better the picture but it's never going to be as good as transferred to your tv in 1080p resolution. (bluray)
now that being said, 720p tvs look great. i just bought my dad a 50" 720p samsung plasma for 1100 shipped brand new in box and the tv looks brilliant. i just bought myself a 720p projector and its great too. you are not missing out on any resolution on regular/dvd/digital/hd signals, only on sources that output higher than 720p. dont let the 1080p/1080i argument stop you from buying a tv, but dont think they are same thing.
