If I set my PS3 to 1080p will I have picture with my 720p plasma?

If I set my PS3 to 1080p will I have picture with my 720p plasma?

depends on wheter the TV will ACCEPT 1080p signals. Probably not. Honestly I don't see the point in this...just output 720p to avoid further re-scaling which will deteriorate the image.

Yeah, you would want to do that why?

If you have a plasma that accepts 1080p input set the p3 to output 1080p.

You get better image fidelity by rendering at a higher resolution and then downscaling that to the display resolution. Granted, even when outputing 1080p some PS3 games still render at 1280x720 and simply upscale that for output, in which case 720p output can look better becuase it aviods unnecessary scaling.

Also, what people often refer to as 720p plasmas aren't actually 1280x720 displays anyway, they still have to scale 720p siginals to their actual native resolutions.

I would try it both ways to see which device has the better scaling - the TV or the PS3. Pick whichever one looks best to you. I have mine set to 1080p and feed my HD70 projector that way. It seems to my eyes that the projector does the conversion better than the PS3 to 720p.

i find that my tv scales everything better so i set it to 1080I and change it to 720p when the content i play or use is 720p.

That really depends on the scaler being used.

Why does my PS3 seem to think that my 50" 1080i plasma is 1080p? When it scans for maximum signal, it auto-selects 1080p, lol. When I leave it there, I get picture and everything, but later on I deselected it, since my display is definitely a 1080i panel. I didn't know if I was start having problems if I left it on the 1080p signal it thought it supported.

Is it a Hitachi?

Anyway, a display can accept any signal it wants and convert it to the native display format of the TV. Just because your TV is a 1080i doesn't mean that the electronics in the TV can't accept a 1080p signal and then interlace it for display.

Yeah, it's a 50" Hitach Plasma P50H401. I got it from Best Buy for $996 the weekend before Black Friday. Here's a link below:

So should I set the PS3 at 1080p, or should I leave it at 1080i?

Probably doesn't matter. I'd probably use 1080i from the PS3.

Probably doesn't matter. I'd probably use 1080i from the PS3.

That's what I figured. At first I left it at 1080p cuz I thought it was cool. Later on, I thought it would be a good idea just to set it to 1080i, as that's its native resolution. I didn't want it converting the 1080p to anything worse than the 1080i, so I decided not to chance it. For the record, Blu-Ray Discs look drop-dead gorgeous on this 1080i set. I'm half way through Planet Earth, and every other scene is just draw dropping!! :)

I have a Panasonic TH50px77u 720p with a direct 1080p input.

Since my panel is 720p native resolution, would there be a good reason to leave it on 1080P? Won't the TV descale the 1080p to 720p anyway? What is the purpose of a 1080p direct input on a 720p set anyway?

quick question then? lets say I have two movies in mkv format. one is 1080p and the other 720p. if i play a mkv file that is 1080P thru my panasonic projector which is only 720P capable it will look worse than if I played the same 720p mkv file?

thoughts?

I'm under the impression that whatever you feed your tv, or whatever inputs your tv accepts, it only truly displays your picture at the display's native (max) resolution. I would also be under the impression that you should not purposely feed your tv higher-than-native resolutions, because then it has to go through the work of downgrading it. Those are just my generalizations.

I hate to state the obvious (no, I don't), but why not try both resolutions and see which you prefer? If you can tell a difference, great. If you can't, then does it actually matter?

^ i couldn't tell the difference, but who knows if there are adverse effects on your panel by making it constantly down-convert the signal and display it? and maybe there's a very small screen lag that causes some form of internal anxiety on one's body? lol, i know i'm going out on a limb here, but who knows...

That really depends on the scaler being used.
How so? I mean, I've never seen a TV with such poor quality scaling that images rendered and input at a higher resolution look worse than ones rendered and input at any lower one, can you name even one TV where that is the case?

Your display isn't 720p native. 720p is 1280x720, while your plasma's native resolution is 1366x768. In general, sending 720p to such a display requires downsampling higher resolution content before outputing it, and upscaling that 720p to the native resolution of your display, where as 1080p output aviods the step of downsampling to a lower resolution and aviods the reduction in image quality which comes with that. In the case of the PS3, no games will render at anything above 1280x720 if you limit the console to 720p output, while with 1080p output some games will render at higher resolutions and the image fedlity will benift from that.

What games were you looking for a difference in? There isn't much difference in many games, as most don't support rendering resolutions above 720p anyway. Try games that actually do render at a higher resolution when 1080p output is selected if you want to see the improvement in image fidelity which comes from rendering at a higher resolution.

And no, the video processer in your display is designed to handle accepting 1080p and downsampling it, doing so doesn't hurt your display and it doesn't add any lag either.

Are you saying that if a game outputs 1080p, and I have my PS3 set to 1080p output, even though my TV only displays 1080i, it will look better than if I were to set my PS3 to 1080i maximum output?

Are you basically saying if a game supports 1080p...

1080p downsampled to 1080i would look better than... 1080i maximum setting, which would probably just display the game in 720p?

So Since I have a 1080p direct input on my 1366x768 I should keep it on 1080p because it is easier to scale down than to scale up?

That isnt' what I was saying, and the games I've seen which do support rendering at a resolution higher than 720p will output 1080i when the 720p and 1080i options are selected but 1080p isn't. If you are actually using a CRT HDTV that accepts 1080p, then whether or not you should use the 1080p output on the PS3 just depends on if the PS3 or the TV does a better job interlacing it, and likely won't look much if any different either way.

It isn't a matter of anything being easier, it is a matter of getting better image quality from rendering at a higher resolution and having your display downscale the image compared to rendering at a lower resolution and having your display upscale it.

Ok I am not sure if my question ever was answered. My tv is a panasonic TH-50PX75U it's native resolution is 1366 x 768. When I setup my PS3 it auto detected a 1080p resolution even though my t.v. only is supposed to support 720p. So will I get better picture manualing setting my PS3 to 720p or just leaving it at 1080p even though my tv isn't supposed to support that high?

thanks guys

how bout this question...

If I feed my tv a 1080p mkv file, which should I set my display as for the better picture, 1080i or 720p?

thanks guys

Keen observation. What's probably rarer than a panel TV without some sort of defect? Women on this forum. Just a thought LOL

Well I didn't really mean just guys only. Thanks to anyone who helps but I'm sure there aren't as many women compared to men on the forum by far.

Did you not read the post from kylebisme right before yours? I asked the identical question

For the record, Blu-Ray Discs look drop-dead gorgeous on this 1080i set. I'm half way through Planet Earth, and every other scene is just draw dropping!! :)

1080i is not your display's native resolution. The P50H401's native panel res is 1280x1080. To my knowledge, there are no fixed pixel displays (Plasmas, LCDs, etc) that will actually display a signal interlaced (like a CRT will). They wait to receive both fields if receiving an interlaced signal and then update the display progressively.

As to whether you want to set your PS3 to 1080i, 1080p, or 720p that depends largely on how the set handles de-interlacing and scaling. According to CNet (http://reviews.cnet.com/flat-panel-tvs/hitachi-p50h401/4505-6482_7-32331463.html), your TV failed to properly de-interlace both film and video 1080i test patterns. This may not noticeably affect the PQ to you, but it could be a strong indicator that its best to send it a 720p or 1080p signal.

You should set the PS3 to output at the maximum input resolution of your TV to minimize rescaling. A 1366x768 TV will ALWAYS rescale the image because both a 720 and 1080 image will have to be resized, whereas a 1920x1080 TV will only rescale a 720 image (unless your TV doesn't do 1:1 at 1080, but that's another issue).

So if you have a 1366x768 TV that accepts a 1080p input, you should set the PS3 to a maximum output of 1080p [note that I'm saying maximum output and not a fixed output]. Then if you have a 720p source, the PS3 should only output 720p and the TV will upscale to 768 (1 rescale). Similarly if you have a 1080p source, the PS3 should output 1080p and the TV will downscale to 768 (1 rescale).

If you set the PS3 to a maximum output of 720p, and have a 720p source, then again the PS3 should only output 720p and the TV will upscale to 768 (1 rescale). But now if you have a 1080p source, the PS3 will downscale and only output 720p and the TV will now upscale to 768, resulting in a worse PQ.

The same goes for if your TV only supports a 1080i input, set the PS3 to a max output of 1080i, and it will not touch a 720 signal, but will have to interlace any 1080p source.

I think I've got that right. :)

People should be cautious of this if they're not sure if their display will properly de-interlace and scale and a 1080i signal. Some may not de-interlace it properly, and others still will bob the signal (effectively dropping the signals resolutions to 540p and then scaling it to the panel's native resolution). In such cases (TVs that bob the 1080i signal instead of weaving it), they're better off just sending it a 720p signal in the first place.

There is a case where the owner of a 720p HDTV (that can accept a 1080i/p signal) may want to use 1080i/p output from the PS3 - overscan. If they set has significant signal sampling overscan (as opposed to physical overscan) then the picture may look better using 1080i/p.

For example:

If signal sampling overscan causes 10% of the horizontal pixels and vertical lines to be hidden (not mapped to pixels on the screen), then the 1280x720 pixels on the screen will be derived from only 1152x648 pixels in the input signal.

When a 1080i/p input signal is used, then the 1280x720 pixels on the screen will be derived from 1728x972 pixels in the input signal. The result will be a noticeable improvement in visible detail.

This is of interest to me because I am using a Toshiba 62HM84 with the PS3. This HDTV is a 1280x720 DLP that has minor physical overscan, a lot of signal sampling overscan, support for 1080i input signals, and no service menu adjustment for controlling the signal sampling overscan. The change in detail (using 1080i instead of 720p) is most noticable when using the PS3 web browser, the text is much easier to read.

Overscan has very little to do with what the difference you are seeing, rendering at a higher resolution provides an improvement in image fidelity regardless of what resolution you display it at.

Every other scene is just jaw dropping because you only have a 1080i display! If you had a 1080p display EVERY scene would be jaw dropping! ;)

If the tv is 1080i native and it receives a 1080i signal, then 1080i = 1080p.
So every scene for both is jaw dropping.
