So if the Vibrant is only 800X480, why does a 720p movie look better than a 480 movie, it seems like the max is 480..... Also, if the Iphone 4 has 960x640, even though it looks amazing, way better than any android, it isnt actually playing a 720p video in full either is it? yes i realize how stupid that question seems to many of you. I couldnt figure out how to search google for the question. So enlighten me if you can. After you give me crap for not searching of course...thanks

What is the resolution of the movie you are comparing it to? What is the format of the movie? How was it compressed? All of this and more affects the resolution of the video. If you have a 720p movie, it my be down-converted to 480 on playback, but because it was compressed at a higher quality (and maybe in a less lossy format), it's going to look better than a movie compressed in standard-definition (and more than likely at lower data rates).
because 720 is bigger than 480, the image size is bigger and usually has a higher bitrate too than a regular 480 video, so if 720 is played on anything smaller than a 720display, it gets resized (downsized) to fit the screen (without any quality loss), in this case a 480 screen. So all those pixels on the 720 video get pushed closer together thus showing more detail on the 480 screen.
a 480 video usually looks just fine on a 480 display, but since a 720 video is bigger and was meant for higher resolution screens, it has a higher bitrate which makes it store more detail than a 480 video, that's why it looks better
thanks for the replies, that makes perfect sense. if its 720 pixels i didnt understand how they could all be on a screen capable of only 480 but i guess compressing the video maintains the quality.
And to answer the questions, i just dl a movie, and drag and drop to my vibrant through doubletwist which takes care of the conversion. Although ive noticed none of the videos i download look nearly as good as default Avatar. I dl 1080/720 movies and they always have the very pronounced, large pixels when there is action and bright colors. But Avatar looks great so i guess maybe i could use something other than doubletwist and get a better quality conversion? Because the Vibrant is clearly capable of displaying fast action and huge varieties of colors like in Avatar
That said im ready for HTC/Moto/Samsung to start popping out some high res displays to rival the I4. The Vibrant has a nice screen but put it next to the damn I4 and it looks downright dull. I guess that tiny 3.5" screen next to the Vibrant's perfectly sized 4" display benefits the I4 visually as well...

don't use doubletwist to put videos on your phone if they are already compatible with the vibrant, like a 720 video, vibrant can handle that..and all I explained was about the vibrant playing back the 720 video without conversion (just dragging and dropping the 720 video to the phone)
you have been playing the wrong movies or using the wrong convesion settings cause my movies look amazing, up to par and sometimes even better than the iphone 4. Have a look at one of my threads and download the video i uploaded (just drag and drop to phone don't use doubletwist or any other conversion method) and you will see what the vibrant screen is capable of.

I, for one, was very impressed by the 'photography' capabilities of the TP recently discussed, but it made me even more curious to know about 'video'. Just ran across a 1080p recording on Youtube. I cannot post the link (too new here), but check the channel for 'ASUSNordicAB'

I agree that this video is not a perfect test, nor is it one being done by an average guy in his home/yard, but to my (undiscerning) eye, it is very impressive for clarity, frame rate, color, and effects. Since this video was released, here is what some of the other sites are saying:
http://androidcommunity.com/transformer-prime-1080p-camera-gets-a-look-at-segways-and-fashion-models-20111129/
"The 8MP 1080p camera is will also meet or beat just about any tablet out there, and the manufacturer aims to prove it with their latest YouTube video. Compare this with the impressive still images already released....An Asus demonstrator walks around the trade floor showing off the 1080p recording, as well as the standard color filters. Though the Transformer Prime isn’t launching with Ice Cream Sandwich, it will include its own video tools, including an interesting time lapse mode that takes one photo every ten seconds."
http://www.ubergizmo.com/2011/11/asus-transformer-primes-camera-demonstrated/
"Everything is shot in 1080p at 30 FPS (frames per second) and looks extremely sharp not to mention there were no signs of frames dropping. However the tablet wasn’t shooting in difficult conditions so it’s not exactly the best way to judge its capabilities. But for what it’s worth, it does perform well with adequate lighting."
http://news.softpedia.com/news/Asus-Transformer-Prime-Camera-Put-to-the-Test-237339.shtml
"The whole video is shot in 1080p at 30fps and the image looks really crisp (at about the same level as some budget Full HD video cameras we would say) with no signs of frames being dropped. Lighting also wasn't ideal as the video was shot indoors, so this is another plus for the Transformer Prime."
The video definitely seems to look good. I am curious how good the audio that goes with it is though
In the market for new tv. Is there a big difference between a 1080p and 720p tv? is it worth the price difference?

Where in the world are you that you can still find 720p sets for sale? Are they on the same shelves as the CRT TVs?

Best Buy is selling a 720P Dynex TV for 249.99. I have had my fair share of HD TVs and I must say anything over 32'', 1080P is preferred. 32'' and below, you won't notice the difference between 720P and 1080P. Again, my own opinion.

it depends on a few variables. How far away will you be sitting? How big is the screen?
I have a 62" 1080p in my bedroom. It is a large bedroom and my bed is about 14 foot from the screen. I like the extra resolution at that distance.
I have a 50" 720p in my living room. my couch is only 10 foot from the screen. It is fine at that distance. If I push my Couch back to where it would be closer 12 foot away though, not as good.
I say a 720 is fine on 50 our less as long as you aren't sitting too far away.
But it also depends on how much difference in cost you are talking. A few years ago there was several hundred difference between the two. Now I think the gap has closed.
I would opt for the 1080, but the 720 wouldn't be out of the question.

yea i got a 720 p 32 inch and it looks just ass sharp as the 50 inch 1080 p in the other room i say if its a small tv 720 p is fine but if its over 32 i would get 1080p
I bought a 42 inch insignia brand 720p plasama for 185 on black Friday
I only use it for my xbox 360 ... It really all depends on what it will be used for... And most things upscale to HD.but that is a whole other topic/debate
Personally i dont see a difference in a tv thats 32" or smaller.
Everyone has hit it right on. 32 inches and less no user discernable difference between 720p and 1080p. Larger than 32 inches I would not get a 720p, however there are not many available anymore.
Also to consider is the source.
Blue Ray is 1080p
HDTV depends on the service (satellite, cable, etc.) but most TV is either 1080i or 720p and from what I've been told the way 1080i scales on a 1080p tv it is no better than 720p.
Also, different carriers compress their signal more or less. My experience has been that Time Warner really compresses theirs and so HD on Time Warner Cable looks like crap. I have Dish Network and it is great. Some Prefer Direct TV, but I have always thought my Dish Network service is the sharpest.

I was going to say that most only see true 1080p from blu - ray. But want to add that netflix only streams 720p.
Comcastrated
Get the 1080p tv and stop looking at those 720p ones less your looking for a tiny thing.
end of story.
Just as everyone has said, it really depends on what you are connecting to it. I know what you are talking about, and right now, you can get a steal of a deal for a 50" plasma 720p for like 6ooish. Who is your cable provider? Do you have HD setup? Do you have a blu-ray player? Are you connecting a ps3/xbox to it? Personally, I would rather have 1080. It's not that much more price wise. You can get a 51" samsung 1080p for 899.
http://www.brandsmartusa.com/Products/1467-Plasma-Flat-Panel-Television
Even the 3d TV's are dropping in price too. Look around at Brandsmart, Hhgregg, tigerdirect.com, newegg.com, and microcenter.com. Some of the best prices I've found. I'm in the market for a 50" 3d tv, but haven't found the one just yet.
1080p or higher.... Nothing less.
If you have the money go for 4k x 2k
I use my 32" as a computer monitor so 1080p is Needed otherwise everything would be huge..its got 3D too so I'm all set. $500
Nothing fancy,just a Vizio.

Unless you are using a CRT 1080i is not as sharpas 720p FYi. 1080i is interpolated from 2 560p images. CRTs are designed for interpolation and LCD's/Plasmas are designed for progressive "i" vs "p". So on an LCD/Plasma you are going to lose quality. So in the case of HD screens bigger #'s don't always mean better. Also refresh rates and contrast ratio are other factors you need to look into. The bigger the Hz the better, the smaller the Ms the better and the bigger the contrast ratio the better.
If you never saw a movie 1080p and ony ever saw moveis in 720p you wouldn't know you were missing anything. If you aren't bothered by the fact that you will know there is better out there and the movie you are watching can look better, then 720p will be the better choice. If that will eat away at you whenever you watch a movie then get a 1080p because you will end up with one anyway.

Cheers.
I just sold my transformer prime infinity...and coming from that, im disappointed with the screen. How could a lower resolution screen on the prime look sharper than the one on the nexus?
Well I was just looking around here and I don't have a Nexus 10. I got a Galaxy Note 10.1 and from my experience the picture matters a lot.
I mean there are a lot of wallpaper sites with ultra HD and optimized wallpapers for retina display, but the same resolution is not always the same sharpness. some are crappy cropped or zoomed.
Use quickpic to set your background picture. The stock gallery app sometimes crops the pictures false.
And pictures with a resolution below the maximum resolution will always look a bit crappy. that means that when you are using a fullHD picture, which was nice for transformer prime, it can look less sharp on a display with higher resolution like nexus 10
I too come from Prime and there is no contest, this screen is sharper than Prime by miles.
How stuff looks will depend on what you are seeing.
If you have set regular wallpaper, it will look all blurry thanks to resolution. Even so called HD wallpapers will look blurry on this. You need to go search for wallpapers for MacBook Pro retina and use those on this tablet using quickpic. None of the apps from Android market have good wallpapers that are having native resolution of this tablet.
Text is sharp and crisp on this.
Most arcade games are not optimised for this screen and look terrible or blurry. That is not screen's fault.
Desktop web pages look nice full and crisp. So only real issue of lack of sharpness comes into picture when the content is not ready for screen. That includes apps, images and games.
I also come from Prime.
I wouldn't say the Prime screen looks sharper than the Nexus 10. Reading text on the N10, for example, the resolution is really amazing, very nice on the Nexus 10.
The colors and brightness and blacks is a different story. The Prime had those 3 much nicer than the Nexus 10. I loved playing Marble Blast on the Prime, the graphics looked amazingly vivid. On the Nexus 10 they appear as meh.
Its the prime infinity. Drastic difference. What a shame. Gonna put the nex up 4sale.

It's mainly because a lot of apps and mobile sites and such aren't made for the resolution. It's made for a smaller resolution, so to make up for that, the apps, mobile sites, and whatever else are all upscaled to fit the 2560x1600 resolution. While upscaling allows you to view things bigger, it will also make everything else a slightly blurry. There are upscaling algorithms to make it look better, but basically it's impossible to make upscaled images look as good as a native 2560x1600 image.
A 720p 10" screen (Note 10.1) will show a 720p video the cleanest because the video outputs a ratio of exactly 1:1 pixels.
A 1080p 10" screen (TF prime) will show a 720p video a bit blurrier because the video outputs a ratio of 2.25:1 pixels.
A 1440p 10" screen (N10) will show a 720p video the blurriest because the video outputs a ratio of 4:1 pixels. (I know the N10 has a 1600p screen, it's just to make calculations slightly easier)
Now when using a 1080p video, a 720p screen will show no improvement because the screen can't output those extra pixels.
When using a 1080p screen, the screen will look sharper than that 720p screen because you have more information. Consider watching TV of a 10x10 resolution vs 1920x1080 resolution. The 1920x1080p resolution will look far better
Once again, the 1440p will look slightly blurry.
Now when you use a 1440p video, you can probably guess which screen will output that video the cleanest.
So basically, this high resolution thing is good mainly for texts as of right now since nothing is really optimized for a screen beyond 1080p.
Anyone who thinks its possible for a much lower resolution screen to be sharper is a fool. This screen is absolutely dazzling. Though content displayed is obviously going to have an affect.
And just to shove some numbers in your face:
N10 - 300.24 PPI (2560x1600 @ 10.055") 4,096,000 pixels (78% MORE)
Prime Infinity - 226.42 PPI (1920x1200 @ 10") 2,304,000 pixels
That's a huge difference.

I actually have to disagree with you a little bit here. 720p video should look just as good on the Nexus 10 as it does on the Note 10.1. 1280x800 times 2 is 2560x1600. Because of that each pixel of a 720p video will take up exactly 4 pixels on the Nexus 10; however those 4 pixels on the N10 are the same area that would be a single pixel on the Note 10.1. This is a clean ratio. On the TF700 you got to 1920x1200 which is 1.5 times 1280x800. This is not a whole ratio and means that pixels of a 720p video will take up between 1 and 4 pixels on the TF700 display (determined by a fancy algorithm for scaling images).
The Nexus 10 playing 1080p video should have about the same blurriness as the TF700 playing 720p video.

You can most likely blame that on googles new font rendering in 4.2. They turned down the font hinting a lot. It would be nice if it was configureable like in Linux. It the same way on the galaxy nexus and nexus 7 in 4.2.

The problem with this screen is calibration and black levels.
Colors are extremely washed, red is a poor red, same with blue. This totally kills the screen. If you compare this with ipad screen, you will cry. Not because of viewing angles, not because of brightness, because of colours. Google was really smart when they decided not to calibrate their screens, same with nexus 4, while other OEMs take care of this thing deeply.
And black, despite numbers of the reviews, its quite poor, mostly because every single unit has light bleed (some with a hard mess, others this problem is smaller)
As a result, a top screen with such a poor implementation. This could be best screen in an tablet ever, and now it is a mediocre one, with many pixels, but nothing else. And it's a ****ing software issue, thats so sad.

Yep, meant the calibration thing, it's about software. Black thing is because a bad manufacturing process, probably because of low price tag., or crappy manufacturers.

Wow...that blows. Maybe we need a 4.1 ROM??
I saw light bleed as soon as I turned my N10, but that's not the reason I just called to return it -- it was the uneven brightness. The top 1/2 inch of the screen is noticeably darker than the rest of it -- not visible when watching a movie or playing games, but very distracting when surfing and reading books, especially in portrait mode.
Since I haven't seen anyone else complain about this issue, I'm hopeful the replacement will be better.
Yep, I completely agree with one of the previous posters, this is definetly a black level issue. I put the iPad with a Retina Display right against a Nexus 10 both playing the same 1080i MKV. The iPad clearly won.
I still like the Nexus 10 a lot and I find it very comfortable to use because of how thin it is and how light it is, but to improve the product I think Google missed it some here. They could lowered the resolution considerably (1920 x 1080 is more than fine), improved on black level, and used the same processor. The lower resolution would have allowed that processor to scream since it wouldn't have been as taxed to interpolate so many pixels.
I don't know if it is a software issue or not, but if it is I really hope Google releases a fix. If there was a way to adjust Gamma or Contrast it might help considerably.

There's no way on earth text (or other computer generated content like the UI and icons) will look better on a 147PPI display (Prime) vs. 224PPI (TF700) or 300PPI (N10). The reason is as 404 Error did a great job of explaining is that text is a 1:1 match pixel wise; the more pixels the sharper the image. Photos and videos display even the clearest content over multiple pixels so the advantage of a higher PPI becomes less pronounced. And the human eye (even yours) can't resolve sharpness over 229PPI beyond 15". So, your 20/20 eyes are decieving you. The N10 has less contrast and isn't as bright as older displays so that might be what you're reacting to.

Mine has this problem and so do at least a few others. See http://forum.xda-developers.com/showthread.php?t=2007676
I'm still debating if it annoys me enough to justify an exchange.
So I just bought a Homido to use with the nexus 6p. It's fun but the resulting image isnt too sharp. I think this is because demo movies are 1080p generally and since our phone is quite big, the resulting image isnt too sharp. I wonder if someone knows a source for 1440p or 4k SBS movies to demo ? I couldnt find any myself. Not youtube but real movies for download, shot in QHD or UHD. Please share if you've found something in this thread, thanks !
Actually I'm starting to think there's currently just *no* SBS content higher than 1080p, even on the torrents I can't find anything higher than 1080p, that's quite a bummer ... Still, if someone knows a demo or something >1080p, please do share !
Actually so it seems the SBS format only goes up to 1080p24 ... Just starting to look into this, but wondering now if there's a format that supports higher resolutions ?
*EDIT* also just found this article, the makers of the Oculus rift say that 8k resolution per eye is needed to truely get rid of pixelation: http://arstechnica.com/gaming/2013/...esolution-per-eye-isnt-enough-for-perfect-vr/ and the article makes a point that you need even a multiple of that to get rid of aliasing.
Oh and 500 fps, hehe.
That seems still quite a few years away, lol.
Currently virtual reality is interesting but I understand now we're still quite a few (probably 10) years away from hardware that can generate a really good VR experience. 1080p24 just isn't it....
To answer my own question:
Full SBS = 3840 x 1080 which exists but requires specialist playback equipment
Half SBS = 1920 x 1080 which is very widespread and also of course broadcast-able.
So Full SBS is actually 1080p *per eye*, so our display cant yield true full SBS unfortunately.
