I'm looking into HDTV's and there is a set I'm interested in that does 720p but not 1080i. Is there that much of a difference between the two? I would think that 720 lines per screen is better then 540. Any comments or opinions would be greatly appreciated.

Thanks

I would prefer 720p over 1080i.

What set does 720p but NOT 1080i?!?!

720 lines over 540 lines is better only if you have the ability to see things at 1/60th of a second. Since no human is capable of this you will see 1080 lines painted every 1/30th of a second looking better then 720 lines!

Except for Panasonic, it's almost always the other way around -- 1080i supported, but not 720p.

Logical, but not necessarily true. The scan lines from interlacing can cause all sorts of anomalies and artifacts, while a prog-scan image will be perceived as more film-like.

Samsung is getting ready to release a Table top projection screen in a 40" (HLK436W) and a 50" (HLK506W)that does this. I've seen the earlier models and they look pretty good. I have a problem in the my HT is in the basement and because of the Hallway anything even relatively large will not fit. So the size of the 50" will get me what I need and still be able to get it down stairs. If you go to samsungdigital.com and look under TV's for these models you'll see them. I'd be interested in what you think of these sets as well.

Bumping it up. Hoping someone can tell me if they notice a difference between the two. Or any other comments.

I think I read that the 720P standard is better for film and 1080i is better for video...or is it the other way around? Most reviews, however, seem to give 720P the nod.

IMHO, 1080i is better than 720p.. 1080i HDTV is the most spectacular image you can get out of a TV... The most lifelike, sharp, vibrant, clear...

I would think 720 to be better. 1080 is interlaced, so it's actually only 540 lines. 720p IS 720 lines of resolution. The more the merrier

I would agree, however I have not seen them so I can't tell you first-hand. I do know that I set my home theater computer's resolution to 540p which is essentially 1080i, so I would expect 720p to be better.

I have not seen any of the above anomalies on any decent HDTV's and up. Maybe some no-name cheapo HDTV's that will come out in the future but outside of that 1080i will be solid through and through. Of course the source has a lot to do with picture quality but that would effect 1080i as well as 720p.

Not so. In reality 720p shows 720 lines every 1/60th of a second and 720 lines every 1/30th of a second. 1080i shows 540 lines every 1/60th of a second and 1080 lines every 1/30th of a second. Because humans can't perceive things at 1/60th of a second that makes 1080i a higher resolution image as humans can perceive things at 1/30th of a second.

Some pretty interesting comments by everyone Thank You.

But I guess my bottom line is. Will I be disappointed with a Set that only does 720p when I see someone else's 1080i?
