720p Vs 1080i
« on: January 19, 2006, 10:28:00 AM »

It's not just you.  People aregue all the time about which is better, but visually it is hard to tell the difference.  I would recommend just sticking with 720P because of the progressive scan picture, but honestly you probably wouldn't notice a difference most of the time.

You'll be sorry you dropped $$ on a 1080p set just because the ps3, on paper, says it will support it. Your average game will not run in 1080p, not for a while anyways.

You wont even be getting a ps3 for almost a year(if youre in Europe, 3 years if youre lucky). Do you know how much 1080p sets will drop in that time? You should be in absolutely NO rush to buy a tv now, for something that in reality doesnt even exist yet. Nothing concrete has been said about what resolutions it will play games in.

the "i" in 1080i stands for "interlaced"

wait for toshiba's SED tv,... it's supposed to come out this year, (prolly before ps3)... and it does 1080p but it blows lcds, and plasma out of the water hands down,.... should be comparably priced also,... i'd wait for it,....

nevermind plasma and lcd, its blacks are better than dlp and close to CRT, and Yes they should be cheaper at the onset than past technologies were when they were introduced.

I havent done any checking, but can this tech be used in projectors? I might have to do some research on that.

I cant stand tv's after having a projector for a couple years. If its TVs only, I might have to break down and try one.

as far as i know its only tvs.... but who knows, it may come to projector technologies....the problem is its owned by toshiba and i dont know if they make projectors.... so until they sell the technology you may be stuck with their tv.... its supposed to come out in a 55" model, so thats at least a decent size.....

and yes, the blacks beat crts and rear pros and dlps,.... the reason i compared to lcds and plasmas is because it is still a flat screen like them.

Deftech is there going to be a big difference between 720p, 1080i and 1080p?

Between 720p and 1080i there is almost zero visual difference, but 720p is better IMO. Between 720p and 1080p, there will be the same big difference you see from 480p to 720p. I hope that makes sense tongue.gif

Did you know that the PS2 supports 1080i?

do you know how many games support 1080i..... 1

that's right 1 games supports it. Because Sony didn't set any standards for their developers in terms of resolution...

The PS3 is really no different. Sure it SUPPORTS 1080p, as in it's capable of displaying at that resolution, but the games that can output at that level are completely dependent on whether developers are going to make their games function at that level.

MS is REQUIRING that all 360 support a minimum of 720p, that ensures a particular level of quality. way back when the PS3 was first announced Sony mentioned requiring only 480p for the PS3... So chances are there will be very very few games that support 1080p on the PS3.

If you get a 1080p set you'll be getting it for HD Movie playback....

While we're on the subject, Sony seems to have dropped the ball on that one too. HD-DVD players are coming out in March at a price starting at $500, Blu-Ray players have no release date set (not till the end of this year, possibly next) and will be starting at $1200 Both formats will support 1080p

Even still I'd wait another year before buying a new set, next year there are at least 2 new technologies coming out that blow away what's on the market today. Sharp has LCDs with 1000000:1 contrast ratios, Samsung has LED/DLP Rear Projectors that offer 1080p resolutions with low power consumption, huge brightness, and no color wheels with a single chip (relatively low priced too). then there's the new SED tech which offers the thin form factor of an LCD or Plasma with the picture quality and lifespan of a CRT, and the Paper Thin OLED. Pretty much the only tech that's no getting a HUGE upgrade is Plasma, which is just getting bigger but not much better.

So unless you want to buy ANOTHER TV in the next 1 to 2 years, I'd hold off buying one right now.

@Master X
if you want to know more about the different formats view my "AV formats demystified" link in my sig.
The perceived difference on screen is COMPLETELY dependent on the type of TV you're viewing it on.

yeah that game is GT4 (NTSC), but i read some article (can't remember where, IGN or hdgames or something) saying PS2 never actually supports 1080i and that the GT4 developers used a "trick" methods to run that game in 1080i. something like the resolution was 640x540p (540i x 540i) and considering the PS2 don't even have it's own GPU and limited Vram, that was still genius.

i agree with you about "required" set for the developers. but we will get most games for PS3 in 720p same as X360 at first. and maybe after few years we will start seeing games in 1080i and since PS3 is capable (X360 may also do this) of 1080p most game will have no problem to do native 1920x1080p...

IMO as 720p is the "midpoint" of the HDTV resolutions, i think 90% to 98% of the games will be in 720p for both consoles till the end of their life. cos if a games is natively designed with 1920x1080p, and people with SDTV will look shit when that game is down scaled to 640x480p. run a PC game at that mode and you'll see it looks crap compared to Xbox/xbox360 running on 640x480.

The 360 will never do 1080p.

It's already been said but not ALL games for the PS3 will support that resolution.  Who knows if even 10% of the games will.  It's up to the developers who make them.  So as twisted symphony said the only time a tv that outputs 1080P would do you any good is when watching blu-ray or hd-dvds.

I wouldn't go buying a brand new tv for 1080P yet as it's not mainstream enough.  BUT in a few years it will be more widespread.

Once 1080P is more popular and supported you WILL notice a difference between 720P and 1080P, but it's too early to start investing.  I have a two or three year old tv, that I hope will last me long enough for 1080P to become common enough and cheap enough that my next tv will support it, and by that time hopefully 1080P games and next-gen dvd's will be commonplace.

Keep in mind that 1080p has a max refresh rate of 30fps. 1080p30 is the same as 1080i60 if each field was  framelocked. For most television 1080i60 looks better than 1080p30 because the footage is more fluid, artifacts introduced by interlacing are mostly eliminated by your brain.

1080p30 is not suitable for gaming because if you can't make the framerate you drop to 15 fps, unlike 720p which drops to 30 which isn't as noticeable.

falsh or unclear statement, as it is not PS3, but the HDMI technology is uncapable transfer 60fps at 1080p. though hdmi.org doesn't officialy mention this to be true or false.  unsure.gif

but Sony did state that PS3 is capable of 1080p @ 60fps (i know they can bullshit, but so can any other organisation) and while searching i found this:

and this article
QUOTE
While some material will be produced and delivered at 1080p 60fps most of the HD in the foreseeable future will be in the ATSC standards of 1080i 30fps or 1080p 30fps. That means that the display must convert the 1080p 30fps material to 60fps via some sort of up-conversion (or line interpolation) process in order to add another 1/60th of a second's worth of 1080 lines to emulate 60fps.

None of my statements were unclear or false, they were very explicit, clear and based on fact. Just because you have an HDMI interface doesn't mean that the display device can handle the incoming stream of data at twice the capacity it was designed to handle.

1080p60, only it is running with 12bit color. That is 16 levels of Red, Blue and Green for a spectacular 4096 colors total. For 1080p60 it comes down to bandwidth and signal processing power, there simply isn't enough available to deliver 1080p60. You need to decrease frame rate, decrease color depth, decrease resolution or increase compression to stay in spec of the standards. Sure Sony can make custom non-standard hardware that can do whatever resolution, color depth, frame rate and compression, but in the real world everyone will be following the standards. You can't just add a more intensive compression algorith or more bandwidth utilization and still have standard compliant displays still work properly. 1080p60 is a fantasy in the console world, and it will not be something that even targeted by developers for years to come.

Nice quote, especially when you put it in context in the conclusion of the same article:

QUOTE
Many question why they should buy a display that exceed the ATSC standard, (which limits HD to 720p 60 or 1080i 60)? Isn't something that will display 1080i good enough? Pete Putman, noted display analysts, tells buyers "1080p is a waste of your money".
