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.

Hi guys,
I have a doubt regarding the video playback of our galaxies... I'm checking the MHL output, and I have a couple of questions.
The TV reports 1080i, although I'd like to choose 720p, if that's a possibility. In the end the TV's native resolution is 720p.
Also, I'm afraid the video quality, although nice, isn't really hidef. I feel the video is downscaled to the resolution of the phone's screen (800x480), then upscaled to 1920x1080 for the MHL output (and then downscaled again by the TV to 720p). I'll have to say, the result isn't bad, but far from good. Do you know any way to play a video either at 1080p or 720p? Is there a way to choose the MHL resolution?
Thank you!
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.
Does anybody know where I could download high quality 2560x1600 native videos? I really want to see the Nexus 10's screen in full glory! I've searched on Google but couldn't find anything.
Thanks
On a side note: Am I the only slightly bothered by how 1080p videos look on the nexus 10? I completely understand why they look the way they do and in all fairness they still look really good but no where near as crisp on a native 1080p display. I guess the screen resolution is ahead of its time since no there is no video content available for consumer purchase above 1080p (at least from what ive seen). But I still LOVE the screen! :good:

1080p seems immaculate to me, not sure what tablet you're comparing too, but a high quality blu-ray rip isn't that distinguishable from 1600/1440p stuff.
