I'm sure this has been asked before but my search didn't turn anything up.


I just set up my PS3 to output to a Panasonic AE900 720P projector. I set the PS3 display output settings to include 480p and 720p, and skipped 1080i and 1080p. When I put in Blackhawk Down as a test, I noticed on the projector's menu screen that the output was only 480p.


Is it not possible to output BD video at 720p to match the native res of my projector? Am I missing something? Not that 1080i looks bad, but I assume the scaler in the PS3 is better than the one in the projector.

No, the PS3 will not do 720p out on BD.

Yet, they're working on it. There should be a software update in March.

Are they targeting that though? I don't think that's something they're looking to bring (vs 1080p24).


@Gregeas, just check the 1080i box as well - your projectors scaler is probably quite suited to the job.

One cannot be sure about what goes on Sony engineering these days, but my best guess is that they disabled 720p downconversion until they managed to build a new scaling algorithm for that purpose. It seems that Sony is taking the image quality that comes out of the PS3 very seriously, and they rather not support a feature until it's really good than doing a half-assed job...

I tried 1080i and it looked fine with Blackhawk down. That software update will be nice if/when it arrives.


I thought since many games output at 720p the BD movies would as well.

 

[Connavar]

Wouldn't 1080i look much better than 720p on movies?

Because you would see the full resolution (1080 lines every 1/30 sec, well here 1/24) instead of only 720.

 

[gregeas]

The projector is only 720p, so the 1080i gets scaled to that. Not sure if this makes a real world difference, however, but I've always tried to get a 1:1 pixel map when possible.

not if your native resolution is 720p. I can see it on mine very clearly.

It's going to get scaled one way or the other; no reason to assume the job would be done best on the PS3. Though if Ninjanki is correct, maybe that will indeed be the case.

720p looks better than 1080i into my AE900, but 1080i looks better than 480p.

I second that. I have the same projector, and would like to see the ability to output 720p.

Small question about pixel mapping on Blu-ray movies. It is my understanding that the movies is encoded for output into 1080p resolution. So technically, doesn't it get scaled either way??? Whether it's your projector scaling it to 720p or the PS3 scaling it to 720p and then outputting it?

If it's sent as 1080i to your 720p display it does get scaled down to 720p. BUT. Most displays take 1080i down to 540p then upscale to 720p. This causes a loss in resolution.


If the source (player) does the scaling it can scale from 1080p to 720p which means were getting a 720p picture.


Unless you have a multi-thousand external scaler then this is a issue. The Sony PS3 basically said screw you to all the 720p owners. Every other HD product can do this. I don't even consider the PS3 HD compliant because of this.

Thank you. This is a big issue imo. I'm surprised you don't hear more complaints about this. Especially considering that most hdtvs out there are 720p.

Most people probably don't know. The PS3 by default auto detects max resolution. On my 720p display it set 1080i as max resolution. I put in a BD movies and it plays just fine with 1080i. What most people don't realize is that they are indeed losing resolution.


The fact the PS3 can't scale is a HUGE issue. The 360 has zero problems doing it. One would think the PS3 would at least match a console that came out a year ahead of it in technology.

The original japaneese frimware allowed 720P BD movie playback, I hope Sony re-enables the option. I don't understand it, and I hope the earlier poster was correct in saying that they needed to fix the PQ with 720P...

This is kinda my point, blu-ray movies shouldn't be outputting in 1080i. They should be output in 1080p. So would the display take it down to 540p then up to 720p?? It would stand that it should just drop it from 1080p to 720p. And on a side note. If your set only takes 1080i, I assume the playstation either passes the 1080p signal and lets your set de-interlace or it de-interlaces and passes 1080i. Can anyone confirm with how the PS3 passes the 1080p signal to non-1080p TV's.


And while I appreciate your comments, my question still stands to the 720p 1:1 pixel mapping crowd. Bluray or HD-DVD material is not encoded to play at 720p, it is 1080p material. Whether or not the player does it and sends it to the TV or the TV does it, your still getting scaled material and thus defeating the whole "1:1 pixel mapping: idea anyways. I understand that when using component or other non-digital signals that it is beneficial to do the converting at player side to avoid noise introduction being scaled, however, I'm sure most people on this forum and this gentlemen running this projecter is doing so with an HDMI source. So, in a nutshell, I cannot see how the playstations lack of ability to output 720p affects your 1:1 pixel map cause the source material isn't 720p.


OR


Do I not have my head wrapped around the concept material?

Where did you hear this? I hope it's true. I have a 50" Elite plasma and a Sony ES3100 upconverting DVD player. The PQ is much better when I let the player do the upconverting rather than letting the plasma do it.

What is strange about this thread is that I have a 1440x960 native display which I use with my PS3. It will sync to a 1280x720 signal, and using a HDMI->DVI dongle I can watch BD-ROM's at 720p. I am sure it is not running at 480 (if I manually disable 720 output on the PS3 it is obviously different).
