1080i vs 1080p Looks so much different..I think

[J_WILL_GV]

Ok, so here is my beef, I have a PS3 and a native 108i sanyo LCD ( about 3 years old ). I notice quite often that when I go to a home electronics store and see the blu-rays playing on 1080p LCD's, the PQ is mind blowing...like better than reality..crisp, clear...I mean just astounding. Than we have my own LCD, while the PQ is def above DVD qualtiy, and very crisp, bright and clear...I am in no way confused at whether I am watching a movie or looking out a window at real life. I have the proper full HDMI 24k chords by sony made for the PS3...is there that much of a difference between 1080i and 1080p? Or is it just my tv

Thanks,
Josh

1080i is interlaced and 1080p is progressive what this means is that you get the full frame each time, not half the frame each time. Plus the newer sets are capable of 24 frames per second, the same as film whereas your 3 y.o. model is probably 60Hz (frames per second). This requires a 3:2 pull down scheme to be employed to convert the film material to video material.

You have a Sanyo LCD 1080i.
Now what TV brands are you looking at in the store ?
Not to be critical but Sanyo is not the best TV out there.You could find another 1080i TV that Would give you a better Picture.

I have a 1080i Plasma which is about 8-9 feet away from my viewing and i get an excellent picture and take fully advantage of my Blu-player .

Here it goes
If you get an 1080p TV and your viewing measurements are 10 feet or closer then getting a 1080p TV is worth it . You will see a difference.

If your 1080i TV is farther then 8-9 feet then it should look the same

size of the TV matters as well.If your looking at anything below 50" i wouldn't worry so much about it.

Remember that there's good TVs and bad of TVs.

If you put your Sanyo 1080i to a Pioneer 1080i you would see a significant difference

I hope this helps

Depends on the size of the set. If you have a smaller HDTV you will not see the difference. But you also have to remember that all TV's are not the same quality.

What's the size and model of your Sanyo?

1080i LCD are generally 1384x768.

When you feed them with 1080i they generally do this :

1920x540 (1 field) and rescaled to 1384x768. The number of TV that combine both field correctly before downscaling is rare.

So you are probably getting less than 720p horizontally.

That's why 1080p TV look better. Putting you're PS3 in 720p for blu-ray should score you a bit better PQ, there's still scaling but at lest you're getting a full progressive frame

If the display is progressive and the source is progressive, then there's no difference between 1080i and 1080p. The 1080p source frame is split into two identical 1080i fields. The two fields get sent to the display where they are re-combined into the original frame. The problem with 1080i comes with recordings and TV transmission, where the two source fields are not identical.

All the HDTVs for sale now are pro-scan. I had a Hitachi back in 2006 that was a "real" 1080i HDTV. I think the res was 1080x1080 .

As ryhooki says (quoted for reinforcement), you aren't really comparing 1080i to 1080p. You're comparing a messed up 720p to 1080p. There are no native 1080i LCDs.

It's very hard to compare 1080i to 1080p - the only native 1080i things are CRTs and doing a comparison between formats on a CRT and LCD is next to impossible - they are different display technologies, so the differences you would be seeing would be based on a number of factors. On an LCD the difference between a 1080i and 1080p disc is going to be pretty hard to spot for most people (because even poorly done conversion is good enough in many cases) - if the display does the conversion properly, then you shouldn't be able to tell a difference.

1080i has a stigma on it mainly because in almost all cases 1080i is used on 720p screens (and they don't typically do a good job at converting).

I have a 1080p LCD so I'm just guessing here. But, I would suggest that he set his BD player to output 1080p not 720p unless his TV doesn't accept 1080p. If it accepts 1080p, it'll be down converted to 768p. I think that would be better than setting the player to output 720p which then gets upscaled to 768p. Just a thought.

Blu-ray newbie here so enjoying and trying to learn from all the expertise here!

So, we have a brand new Sony Blu-ray player BDP-S380. It's connected by HDMI to our 4-year old Sony Bravia 32" 1080i LCD. When I switch input to the Blu-ray, the TV says it is sensing a 1080i signal (just as it says, for example, 720p when I switch to our Apple TV.)

I guess I'm still not 100% clear on what resolution is actually being sent to the TV when playing a Blu-ray disk in this setup. Is it, as the TV senses, 1080i? something else?

I ask only because we're not "blown away" so far by the difference in picture quality between an up-converted standard DVD and a Blu-ray disk. I haven't yet had a chance though to compare the exact same movies on DVD and Blu-ray, but that is my plan if I can get to it this week.

Thanks!

Depends on your tv. I have an hd crt with IVTC and line doubling and the phosphors allow for both lines drawn to be on screen at the same time (plus my ATI card has great pulldown detection and vector adaptive de-interlacing for my PC use). The only difference I ever notice is in a very few panning scenes in some films that aren't as smooth as they could be (Like in Halloween 6 on the Alliance disk and the panning to the October 31st Halloween title card scene).
Comparing films in 1080i on my 38" crt to 1080p on a newer lcd of similar size (just a few inches larger) offers no real differences (other than the crt having superior overall picture). I have a friend with a new 60 something inch Quattron and again there's no real differences.
That's 1080i with a crt though, tv's that are made for that output, and until FED tv's start to come out (they are in development; they are essentially much improved lcd thin crt's), what you really need in your tv to get the best 1080i picture is a good de-interlacer. TV's usually have a film or movie mode that sets the inner circuitry and settings up in a way that is best for 1080i content, there may also be de-interlacing settings as well.
