what looks beter for blu-ray movies 720p or 1080i?

1080p....rajeev101

well 1080i because blu-ray does not do 720p if so it will down scale it to 420p. so if your watching blu-ray at 720p your really watching it at 420p.GARRYTH

720p Blu-ray and DVD upscaling

When the PlayStation 3 launched, the reviews could best be described as tepid, as the functionality and many promised features just weren't there. But we live in an age of online updates and changing firmware; with this week's 1.80 firmware update, the PlayStation 3 has become a very impressive piece of A/V goodness. The features are finally starting to catch up with the promise of the hardware, which is to say that the PS3 is now coming into its own

The biggest fix is that Blu-ray discs can now run in 720p. This is an overdue improvement and clears up one of the things that has held the system back from being the best Blu-ray player value out there. Now anyone with an HDTV need not worry about resolution compatibility issues

i have a 42inch sony and im just curious because ive been running them on 720p but today i bought a new movie and in the back of it ,it says nothing about 720p just full 1080p and 1080idanjam2007

If your screen is not 1080p, then it's 720p. Not LCD runs in an LCD mode, (even if you have a LCD Rear Projection Sony). So it's best to just use 720p. And yes, Blu-ray can play at 720p, it's just the disc comes with 1080p to support that and everything under. The PS3, like someone posted, had a problem until the 1.8 that added 720p playback.

Now, depending on the tv exact resolution and video processing, there could be a benefit to 1080i. So lets say if you screen is truely exact 720p, which would be 1280*720, you then would want 720p. Though, many come at 1366*768, slightly higher than 720p. This means you have extra resolution you could possibly use. Giving it 720p then upscales to that 768p, so bascially it still looks like 720p. But if the tv handles 1080i well and downscalesit to 768p, it could look slightly shaper. Compared to games, movies run under 30fpsso that 1080i limitation isn't a problem. Though, if the tv doesn't do perfect inverse teceline with 1080i, which most don't, then during fst motion you might see as little as 540p in detail, then slow motion will creep back up to max 768p detail where it can better deinterlace the 1080i.

What does this all mean? If you screen is exactly 1280*720, use 720p. If it's 1366*768, use 720p for action movies with lots of fast motion. If you want to use 1080i, do it with slow movies like comedies and it might be a tad sharper overall. For games, always choose 720p.

if you're going to watch a documentary such as planet earth, i'd go 1080i, but 720p for anything else

1080p....rajeev101

why? most games will be upscaled....

I use 1080i for everything. If your screen is LCD, it is natively progressive anyway, there's no interlacing. And movies are 24 fps, not 30.lostn

Yes, movies are 24fps, but the PS3 and all other players have to convert it to 30hz to then even 60hz with 720p, and I don't think hist tv supports direct 1080p 24 feature.

There's no interlacing, but the tv has to first deinterlace 1080i so there still can be some side effects during fast motion. Not even some of the most expensive 1080p tvs can properly inverse teceline film from 1080i back into 1080p. Only a couple, like the last JVC LCoS rear projection, but Sony and many others failed to resolve all 1080i lines from 1080i HD movies. The same will happen on 720p TVs, using 1080i during fast motion probably only gives you 540p, but it deinterlaces better with slower motion.

1080i for me (may depend on the TV)

example : I first watched The Phantom of the opera Blu-ray in 720p, image was nice with fine details, but nothing particular

Then I watched it in 1080i : great screen depth (impression of depth for characters and objects, making you feel a character is close or far away), rich colors ...

well 1080i because blu-ray does not do 720p if so it will down scale it to 420p. so if your watching blu-ray at 720p your really watching it at 420p.GARRYTH

1. yes it does downscale now

2. no such thing as 420P.....

1080 pazimiballer

not the question. this answer can be concidered trolling
