For this column, I'm going to go real-world on you and step into our A/V lab, where Mr. Katzmaier and I have set up five flat-panel HDTVs with native resolutions ranging from 1,024x768 (the Philips 42PF9631D 42-inch plasma) to 1,366x768 (the Panasonic TH-50PH9UK 50-inch plasma) to 1,920x1,080 (the Westinghouse LVM-47w1 47-inch LCD, the Sharp LC-46D62U 46-inch LCD, and the JVC LT-40FN97 40-inch LCD). We've hooked up the Samsung BD-P1000 Blu-ray player running the latest firmware and are using a Gefen HDMI Distribution Amplifier to pump out images to all five TVs at the same time. Then we pop in Mission: Impossible III, one of the best-looking Blu-ray movies we've seen to date. Our mission: see what differences we can discern in the picture quality at various resolutions.

Ultimately, we agree with the Imaging Science Foundation (ISF), a group that consults for home-theater manufacturers and trains professional video calibrators, when it says that the most important aspect of picture quality is contrast ratio, the second-most important is color saturation, and the third is color accuracy. Though resolution may be the most talked-about spec these days, it comes in fourth on the ISF list, and after you sit watching five TVs lined up side by side, you understand why. The fact is a relatively pristine high-def source such as Mission: Impossible III looks sharp on just about any HDTV, and your eye, when looking for differences, is drawn first to things like depth of detail in shadowy material (black levels) and the color of the actors' skin tone and how natural it looks.

The difference between the two is not noticable but some people seem to stress that 1080P is the holy grail of HDTV. I kno wI am not buying another television because what I have is 1080I.

Maybe some people don't want to admit that they spent a shitload of money for little difference.

i agree. as it is some 360 games looked awesome in HD at launch. adding more lines is just consumer friendly hype smile.gif.

i think i standard needs to be setup for HD thats made final. all these resolutions do NOTHING for the consumer who just wants to be able to see the picture. sdtvs never had this issue; just plug it in and watch.

It all just depends on how big your TV is. If you're running a projector with a 12 foot screen, then yeah--a 42" tv, no. Even on Lumenlab (diy hd projector site), the best results are coming more from color depth and shade levels than anything else.

Also, although a direct comparison was difficult because we had to switch back and forth between 1080p and 1080i output on the Samsung player, we couldn't discern any difference between those two resolutions on the Westinghouse.


i didnt think 1080p was as big a deal as they try to make it out to be.

i watch HD-Discovery and im blown away time after time when i catch an outdoors show, or something underwater... its amazing...

i guess id have to see it in 1080p to see for myself, but im sure these guys are pretty accurate with saying they didnt notice a difference.

1080i and 1080p are the exact same resolution and have the same lines of resolution. The only difference is that one is interlaced and the other is progressive. They are going to look the same.

I have understood for a while that there is no difference in picture quality between the two but some companys want 1080p to give them the lead in product marketing.

until 1080p60 comes out and tvs that support that resolution things will look the same and play the same.

I have an EPSON EMP-TW500 LCD Projector. I can spot the difference between interlaced and progressive very easily on my 120" screen. It's extremely obvious. Interlaced images look much better on a CRT screen than they do on a Plasma or LCD (and dlp) display unit but progressive images look much better on natively progressive display units like Plasmas, LCD's ect.

The article is correct resolutions this high (720p and 1080i/p) don't play a major role but I argue they still do play a role. Because my projector is native 720p I try to stick to that resolution as best I can for the best results. So 720p will by my setting for all Xbox 360 games and HD DVD movies regardless of what higher resolutions they may support. I will use the same settings for the PS3 aswell regardless.

If Xbox 360 starts upscaling games and video to 1080i/p I don't see the point as the games are still 720p native and DVD's are 576p at best.

I am plaing GOW and COD 3 in 1080p (60Hz) on a Sceptre 37 in. NAGA ...it is AWESOME...you guys obviously havent seen this yet.  The difference between 1080p and 1080i are huge.  Its like comparing 480p widescreen to 720p full frame.  Once you get set up correctly and fire up GOW then come back and re-post. rolleyes.gif

Dude, either I'm crazy, or you dont know what you are talking about.

If you talking about GOW and COD3 in Xbox360, I'm pretty certain they dont even support 1080p (unless I'm crazy...)

He's just playing it upscaled to 1080p.

The only advantage of 1080p (using it for TV, movies, gaming consoles) right now is that when there's a lot of fast motion it will look slightly less blurry-and that's about it.

For PC use though, it is a huge benefit to have 1080p.

There is one thing though - I think we can all agree that the difference between 1080 lines and 720 lines is a lot more easy to see than the difference between 1080i/p- keep in mind that digital panel displays will only be able to display 1080 lines (1080i or 1080p) if they're 1080p native, otherwise it'll be just 720p.  There's no such thing as a 1080i native flat panel if you know what I'm getting at.

Splinter Cell is 1080p.  And ya to the guy that sad more lines, its the same amount.  With 1080p it refreshes at once and there is no flicker like 1080i.  And 30hz instead of 60hz.

To tell you the truth, I can tell the difference but it is negligable.

Yeah right, we dont need 1080P Wishful thinking at best  cool.gif

Production studios master in 1080P, not 1080i or 720P for good reasons.

Going from interlaced to progressive is an impossible task to do perfectly - and the best consumer level method is an external video processor like the ISCAN VP50 costing $US3000.

There is only two reasons why people could not easily see how much better 1080P is from 720P

1. You have vision problems
2. Your too far away from the display to fully resolve the image

the ISF specifically states that resolution is important, and it is part of the tests used to properly calibrate displays to the standards.

Yes, there is.

I bought a 720p set. It looked great. I had problems with it (manufacturer defect that didn't affect the image) and was able to upgrade to 1080p.

I was floored.

720p content looks better, 1080i content looks better (obviously) and 1080p content looks incredible.

Yes, the games output at 720p. I don't output my 360 at 1080i or p because it's just upscaling the image. My display scales it up anyway, so I let it do the work and leave the extra horses in the 360.

Think about it.

1280 x 720 vs 1920 × 1080. Which do you think looks better? Even when scaling a 720p image you are getting a sharper image.

When you dislpay 1080i on a 720p set, you are LOSING resolution. You are scaling down 1920 x 1080 down to 1280 x 720. Just because a display ACCEPTS a 1080i signal, doesn't mean it DISPLAYS at 1080 resolution.

Night and day. I don't see how you guys don't see it.

My HD DVD player looks FAR better on the 1080 set. Yes, I know that it outputs 1080i, but the source is 1080p so all 1920 × 1080 lines of resolution are there, and my display deinterlaces.

This is so funny, I seem to remember everyone and thier mother just a 2 years ago saying it made no since to purchase an HDTV that was not progressive now we're saying 1080i is better than 720p and almost as good as 1080P.

Well my expeirence is 1080i on a CRT properly dialed in with a 1080i signal of true HD source material is the best picture you can get presently.

The flat panels may have higher resolutions and be progressive but the just can produce blacks and/or the rich smooth colors that you get with the tube.

That being said,  I've seen alot of sets being I go to J&R music like twice a week cuase its on my way from work,  the best image on a flat panel I have observed is the Panasonic Plasmas at 720P  I think people like the LCD becuase of the brightness.  The screen is so bright when the go to the show room it makes the images look vibrant and sharp but there is not depth and flesh tones look like shit, and fast movements look the tv signal got scambled.

I'll probably get a plasma cuase I could use the extra space but I love the picture on my 7 year old 36" sony trinitron XBR HD ready set.

In my seven years of watching HD tv both OTA and Dish I think I know what is a good image and tubes are still the benchmark.

Get a clue people.....snip......what that means is that whether you play the 1080i version or the 1080p version - it makes no difference whatsoever.   None.  Zip. Nada.  Just like the article says.  Play it back at 1080i, and your digital 1080 TV set is just converting it to 1080p at 30fps.  Since the movie is only 24fps, you lose absolutely nothing.  Full resolution.  Full framerate.  All from a 1080i source signal.  A 1080p source of MI3 gives no advantage.


In fact, it is you who needs to get a clue. Too many of you people are not professionals in these fields yet you try to talk like you are. You have a superficial understanding of a complex field.

If you had of studies this field instead of shooting off your mouth talking about things you don't understand you would realise that it is impossible to perfectly convert interlaced fields to a full progressive frames. Even the best consume level $US3000 video processes still leave interlace artifacts in certain situations.

Not having to do interlacing to progressive from the original 1080P24fps source is a distinct advantage because it eliminates any interlace artifacting.

Amatuer. muhaha.gif

1080p IS the holy grail of hdtv. It's basically the most perfect image you are going to get for the next 10yrs(maybe less). I agree it is not a gigantic leap over 1080i, but over 720p? It's 2x the pixels... The more you can see the better. I think this study is just trying to do some damage control for somebody.


This is true, but contrast and blacks have improved in later generation of LCOS / LCD / Plasma.

SED and Laser will take over eventually.

CRTs are practical for 60" screen sizes which for most viewing distances is ideal for 1080 sources. Think of the THX recommended viewing angle.

To Admins:
The credibility of this site has gone down considerably in the past few months, and it's because of some of the speculative, vague crap on these news feeds. With all due respect, if you have reliable news, post it, if you don't have a newsworthy story, let it go--otherwise you'll have these crybabies detracting loyal members flaming and crapping up good forums that have helped thousands. I respect and enjoy this site, and I hope you keep helping newbs and those entrenched in the mod community.

To those holding bs flags:
If you don't know, don't post acting like you do, because you sound like a moron.

To those who flame:
It's intolerant morons like you that don't have the decency to keep things light hearted, and ruin it for everyone.

I realize the hypocrisy of my flame, but I can only take three months of people angrily arguing instead of debating points like ADULTS.

Ok fair enough, I jumped the gun and for that I apologise. I'm sorry, but I think if you had of explained your reasoning like your thoughts yiou shared in your second post that may have prevented me reading it in the way I did.

However, I dont live in a country that uses 3:2 - I'm on 2:2 and not all displays are good at that. Some dont detect candence different to anything but 3:2. I do understand your point but I'm not American and were not all on those standards.

No worries.  But I'd be very surprised if HD sets in the UK don't have the same capability.  I understand it's a problem with DVDs, but it shouldn't be with any HD disc or broadcast.

To lifter,

Doesn't only 1080p60 have a positive for videogames and 1080p30, which is what is out right now not have any advantage over 1080i even for video games because they are both capped at 30 frames?

The biggest advantage right now that I see of 1080p, upscaled or not, is that you can match the 360 to your tv's native resolution.  I've got a Samsung 1080P DLP rear projection.  If I can send it a 1080p signal then I minimize game lag.

I think 480p can go up to 60 frames a second where 1080i and 1080p30 can only go 30 frames a secon. This means for film they are exactly the same in some sense, but I don't know all the details as to why and would like clarification.

If you have a native 720p display unit isn't the best possible picture going to come from a native 720p source? In other words is it pointless upscaling natively 720p games and video to 1080i even if your 720p display unit will let you see a 1080i image?

On a serious note. I won't go to 1080p, no matter how much better it is (or isn't???), until the sets get cheaper...much cheaper...and since I don't see that happening for a while, I'll just stick with 720p/1080i.

Thanks for the info Lifter, I have been trying to nail this whole technology down for a while, when you get into some of the more technical aspects it can be pretty confusing to say the least.

So in a nutshell with a lcd plasma dlp or lcos there really is no difference in 1080p with a movie.

But with games there can be differences due to framerate constraints/issues.
