"Does 1080p matter?"

barnettgs · 17 Dec 2006 at 22:13

Just come across this thread, it's very good explanation of 1080p and it's something you need to read before buying flat panel tv.

It asbolutely matters because I have one

Good read. I cannot decide if to go for a 42' LCD with "only" 1080i right now or wait a bit until the 1080p get a bit cheaper and buy one of them. At the moment I'm stuck on my 26' Sammy LCD.

32" TV use only- 730P.
32" using with PC- 1080P. None yet.
37"+ - 1080P.

Remember higher resolution means smaller pixels, so if you get dead pixels on a 42" 730p panel, they'll be pretty obvious from seating. If it's a 1080P they're much smaller, so you won't see them.

So you're saying......? wait for 1080p?

I think he's saying - better resolutions become increasingly important as the size of the t.v. increases. Therefore a smaller t.v. might do with 720p, a larger with 1080i & a larger still from 1080p.

The main thing I think is what purposes do you want to use it for - Wii, X360, PS3, DVD, HD-DVD, Blue Ray, All of the above ? That, along with your budget, will help you decide.

Personally I wouldn't wait for 1080p as not much supports it & 720p & 1080i are both pretty great anyway. But who knows in the future ?

But remember that a 1080i LCD/plasma are normally pretty useless for PC /HTPC use..

Thats if your thinking of using it at all with a PC or HTPC..Plus a 720p screen would work much better for gaming..(I.E xbox360/PS3) than a 1080i screen.

This quote below would be the same for an xbox360 outputting a 1080i signal.This is why a 720p signal and display is better then a 1080i one..

Video camera's record interlaced. That is to say that each 50th of a second they record HALF a picture (ie odd lines one 1/50 even lines 2/50th.) If there is no motion in the image being recorded then if you stick the odd and even lines together you get 1080P (if it is a 1080i video recording...which most of these things are). As soon as something moves you are no longer able to just add odd and even lines and get 1080p full res as the odd and even lines come from different moments in time and are HALF resolution, 540lines. This is why when you watch footy whenthe camera pans fast thelines on pitch appear to be serated and jaggie but when the camera stops moving they appear solid again.

If we apply this back to the 1080P display. If nothing is moving then it can stick odd and even together and you have what apears to be 1080p resolution. If something moves......it now has a problem.

I'm playing in 1080i and personally I think it looks better than a 720p resolution.
I'll have a proper look when I get back home.

Me too. I can say the picture quality on 1080i is more clearer than 1080p, plus when I put my VGA from the 360 into my PJ the image goes well off the edge of my screen if I select 1080p from the dashboard. My PJ can support 1080p but its not its native resolution.

Guess I cant use 1080p

Remember it's on panning and fast motion that 1080i signals falls down..

On slow moving and static images 1080i will look very good..

I didn't think you could use 1080i though VGA cable :confused:

Isn't VGA progressive only?

Warbie · 18 Dec 2006 at 13:02

Much depends on the size of the screen. Even on with projector images up to and over 100" people have a hard time seeing the difference between 720p and 1080p at 'normal' seating distances.

It is indeed.

Running a 360 through vga doesn't give you HD options anyway it only gives you a list of resolutions. (1280x720 for example = 720p).

For my tv 720p is bang on. In certain games I get 'slowdown' with 1080i which is not apparent with 720p. Also R6:Vegas looks much noticably better in 720p than 1080i. (please note this is my personal opinion based on my setup)

I just had a go on Gears of War in both 1080i and 720p. To me 1080i looks the better of the two. I wish I can see it on a 1080p to see if the difference is really profound.
