Since I've owned this phone, I've had horrible gray-scale banding. It will happen if I play a movie with a dark scene, or stream a Netflix movie with a dark scene, or view security cameras through a camera monitor application, etc. The banding is *BAD* - 8-bit bad.
Is this just a limitation of the AMOLED screen technology? I don't have this problem on any phone that uses an LCD display. Is there any way to correct the problem?? I've tried changing screen modes and it doesn't help and I'm not sure what else I could do.
Any help would be appreciated.

Going to try to explain this... When I'm using the stock Camera app, the picture is normal. But when I switch to Camcorder, it seems to be automatically zoomed in quite a bit. And when I try to zoom out, it says that since I'm recording in HD, zoom functions are not available.
This is kind of annoying because now I have to step back probably 5 feet to fill the same frame of when I was taking photos.
Is this normal for everyone else too? Or do I have some weird glitch on my unrooted and pure stock ROM?
Yep, mine does it too (stock rom). It only does that in FullHD resolution. I guess the only use middle part of the sensor to read the data to achieve greater speeds, and thus it's gonna be a hardware limitation.
Who need HD anyway ? The lens hardly catch with it. I record 720x480 and I'm very pleased with teh quality.
Change the video recording resolution in the settings pane to 1280x720 and that should fix your problem.

Yeah I noticed that.
But that doesn't make sense. In photo mode, same resolution as video mode but in video mode it's zoomed in. Like Dr. Sid said, it seems that it uses a smaller section of the image sensor to capture video. Which again doesn't make sense. Weird.
This is definetly a speed optimization - scaling down the whole resolution of camera sensor from 3264*2448 -> 1080p is much more expensive operation than just cropping the central pixels, i assume someone at samsung was VERY lazy to have done the camcorder mode in such a lame way, it's still ok for recording outside scenes but useless for in-room recording.
I find this quite annoying also. At first I was wondering if it is a ROM glitch or something, since some of the people here stated that even in stock ROM it is present also.
I hope there is some kind of patch to this, full HD recording is really awesome and I hate to see the 'zoomed' effect.
Yeah noticed the same thing just last night.. Seems to also affect the camera's ability to focus properly in video capture mode as well... Shame on them, I wish I had noticed this sooner.
So I got my microHDMI cable and it works really good except the annoying AR problem with black bars on the sides.
I have seen people saying that video from Googles Play store does go fullscreen, but haven't seen it in action anywhere and can't try it myself because I live in Sweden.
So if Google can do it 3rd party apps should also be able to do it right? Or are they using some unofficial/undocumented API or something? I haven't seen anyone talking about this so I wan't to get some discussions going.

I haven't had a problem with anything other than sound via HDMI. My n10 desktop, google movie rentals and apps that I have run are all at full screen. I don't recall any of them using a different aspect ratio. I just got a new 55inch plasma last week and I did notice the notification bar runs off the screen slightly.
Maybe it's a setting in your tv for that device? Set the tv's settings when using that particular hdmi channel in case they are not global. Try your remote's aspect button in case it is not in the display menu. See if it displays info so you will know what resolution is being displayed?
My son's Samsung Chromebox displays at a very low resolution using hdmi on his tv. Tried every possible setting and he has the black bars on the sides and all the icons and words are so large that the menus don't fit on the screen. Real annoying and looks like an older CGA screen on a pc-xt. (like a 480dpi setting under windows) Tried every cable he could find, every tv setting and it would not display higher 720p. Nothing he could do, we just gave him our old plasma tv and the display is beautiful... Really high resolution.
Same as my tablet, no sound on either of our panasonic tv's... Others work fine... Have you tried viewing it on other tv's.... Could be something is not compatible with your tv and it is down converting the resolution?
Well, those are a couple of things I might look at... Check with others and see if it is a problem for everyone else... Does the n10 main menu show smaller as well? I just double checked and mine runs to all the edges with no "black bars".
I hope something here might help.

I run the TV without scaling/zoom so if you don't see the bars and buttons on your screen your TV is wrongly configured. The N10 sends the unaltered 16:10 picture right to the TV thus the black bars.
I know I can probably distort the picture so it fits with the zoom feature on the TV but that is not a solution, I want a full 1920x1080 output for video-playback without any scaling and distortion of the picture. On my Xoom it would lock the apps to 1280x720 resolution so they fit the TV when you plug in the HDMI cable so if feels so stupid that they removed that feature in the never Android version the N10 runs.
No sound on Panasonic is a know problem if you search around here.

You are right about the apps and the main n10 menus. But if I. Play a movie (tried ice age that came with the tablet and one I purchased off google play) they fill the screen and the info from my tv shows it at 1080p FULL. Meaning that it is not using stretch, zoom or any other screen altering settings. I don't have black line when playing movies back in the play store movie app. I do get them if I try youtube or other apps. Movies play as they are designed to on mine, completely filling the screen (on their own).
I do know about panasonic, that was my point about different equipment!

Good to hear that the play store can do it. So should we ask developers to implement the same thing then? I hope it's documented by Google.

I want to be able to temporarily set my Nexus 10 to render the desktop at 16:9 instead of 16:10 so that when I hook it up to a 16:9 tv via hdmi, it doesn't need to scale the image down and add black bars on the sides. Is there any way to do this? Perhaps an option on a custom rom?
On a CM 10.1 thread, a recognized developer posted some modified files to get 1280x800 resolution or something like that. Not exactly 16:9, but perhaps a similar method could be made to get such a resolution.
I don't know what thread in-particular exactly :/
Aspect ratio has nothing to do with your TV either processing or not processing the image. Unless you are outputting the exact resolution your TV uses then it will always run the input through its scaler. And even if you do run the exact resolution, you still have the other processing the TV does, and very few models of TV's allow you to completely disable this extra processing. You may be able to get rid of most or all of the black bars simply by running a 16:9 aspect ratio, but unless you also run the exact resolution then you will still have processing done by the scaler on your TV.
I'm aware of that, but at least by making sure the signal I'm outputting through the HDMI cable is the same aspect ratio as the TV, it should ensure that the TV's scaler fits the final picture to the screen without any unnecessary black bars, and that's all I care about. It would be nice if Android had an option to specify the exact resolution it outputs through HDMI instead of just duplicating the res of the main screen, but in the absence of that option, I'm looking for a solution to at least get the aspect ratio right.

Mxplayer is implementing the same thing google play movies has where it will go into "hdmi mode"...
I know this isn't a full fix but it will be awesome for movies...
The exynos5 dual supports simultaneous native wqxga (2560x1600) and 1080p at 60fps through hdmi so it should be posdible to scale...
Mabey key lime pie will fix? Well see
Hi,
I have been encountering this issue that my Facebook app always shows the NBA video in 1:1 ratio, which both sides of the screen were cut. Does anyone know what happened?
Thank you in advance.
My sceptre 4k android tv has this weird motion effect that I can't fix, I looked through the whole tv settings and I can't seem to find the right setting for it. Any time there is dark image in motion it flickers the black part of the image. For example if there is a tree the leaves look choppy when the camera is moving. Any help will be appreciated.
