Is there much differance between blueray played on a 720p and 1080p tv, also can anyone tell me if upscalling makes that much differance. Iam buy a PS3 for xmas and wanted some info on the picture quality. Ive got a 720p Tv already and I wanted to find out if it worth getting a 1080p tv and selling on my older one.

Not sure about blu ray, but the OH has a 720p TV and i have a 1080i tv, and when ive played on the xbox 360 the picture has looked much better on mine that his, then again i have a bigger tv (by 10") so that might affect it

1080i is just 720p, it's a 1080p signal, interlaced (down scaled) to 720p, basically.... there's much more involved than that, but that keeps it simple.

If you plan to use Bluray a lot, then getting a 1080p TV is definately worth the extra money, most Bluray movies are released at 1080p.

Not all games use 1080p, and those that don't are simply upscaled from 720p.

Confused how you think 1080i = 720p?

My TV is 720p. I run everything into it at 1080p and let the TV downscale. Looks great :) Maybe start saving for a new TV but no need to buy one straightaway.

if 1080i is same as 720p would it not be called 720p and not 1080i
so whats the point in tv having 1080i and 720p settings if they are the same:confused:

*sigh* I never said they were the SAME... I said that it's just scaled... after doing more research on the matter it seems that I was wrong in my thoughts, and that there are three physical seperate resoltions, but 1080i is accepted by most 720p TV's (whereas 1080p isn't), and down scaled to 720p... again though, this depends on the TV, the Display, and who made it, and what options they put in it...

All I can say is do the research yourself, I can't explain it here and i'd have to copy whole wiki articles to do so :)

all i go on is higher the number the better it is lol
so 1080p is better than 720p etc:hihi:

There are four main HD formats*:- 720i50 720p25 1080i50 and 1080p50. The 'p' (progressive) formats give more detail, but at the cost of frame rate. The 'i' (interlaced) formats give a higher frame rate, at the cost of detail. 1080i is accepted by most TVs because it is the standard currently used for HD broadcasts, and is therefore the most likely signal type that will be seen by a TV. All full HD (not HD ready) TVs will accept all four formats. An HD ready TV doesn't even need to have an HD capable panel, just be capable of accepting 720p and 1080i signals - the most common ones used.

All panels will internally scale the source in whichever format to fit their panels native resolution.

* The frame rates differ in counties using 60Hz mains to 30 & 60 fps.

actually (and this one i'm 100% on) there's 25 and 30 for all formats, 25fps = UK@50Htz refresh, and the US uses a 60Htz refresh @ 30fps.. etc..

Did you read the last line of my post Ghozer?

Did you read the last line of my post Ghozer?

yeah, but its not that it hits 60fps, it's ONLY 25fps and 30fps.. nothing hits 60fps

Interlaced formats hit 50fps and 60fps. They work by sending half the image (odd lines), then the other half (even lines), at twice the frame rate of the full image. Even old analogue video use the same idea, to increase the percieved frame rate without increasing the bandwidth required for transmission.

Just to clarify my statement - The frame rates differ in counties using 60Hz mains to 30 frames-per-second and 60 fields-per-second.

A 1080i50 source will update the screen 50 times a second. A 1080i60 source will update the screen 60 times a second. A 1080p25 source will update the screen 25 times a second, and a 1080p30 source will update the screen 30 times a second.

You actually said "1080i is just 720p", it's in your post ;)

dosxuk, I'm pretty sure there are no interlaced 1280x720 formats, it's progressive only..... http://en.wikipedia.org/wiki/720i

The true framerate of an interlaced picture is half of it's refresh rate though, so you can't consider a 50hz interlaced image to be 'better' than a 25 hz full scan.

To answer the OP, whether you can see a difference would depend on the source material, the quality of the TV's and how good your eyes are.
If I had a 720p TV I don't think that I'd replace it until I could either reuse it elsewhere (other room, relative, etc...) or until it started going faulty.

Thanks everyone for the informed answers, I think I will take Cyclones advice and stick with what I have until it breaks down.
Thanks again.
