Banding, otherwise known as contouring, is a digital artifact common to images, displays or apps of 16bit(thousands of colours) or less.
Gradient image
Viewing the 24bit image in the above link will not show banding on a 24bit display(3 x 8bit channels of R, G & B millions of colours) if viewed in a 24bit app.
If 32 distinct bands are seen, possibly with every 1/3 band being a green shade, then the screen or the image viewing application is not 24bit capable.
Viewing 16bit or lower resolution gradient images on your screen will also show banding.
The Android browser shows banding with this image while the Dolphin HD browser does not.
In short, the SGNote has a 24bit display, which will show banding if viewing 16bit or lower images or using a 16bit or lower viewing application.
More on screen bits
Im noticing lots of banding in lots of different apps :-/
Same here, also happens with Google apps like the Market. Not sure what we can do about it anybody has suggestions?

At least it is not the Note's display hardware that is the issue.
ICS may upgrade some Android OS apps to 24bit.
Thank You for this
This proves that Apps that display banding simply aren't rendering at 24bit.
I was leaning towards there being an issue with the screen as this problem was not noticeable on my previous android devices.
This clarifies everything.
Thanks.

You are welcome.
It bugged me too, until I got to the bottom of it.
Trust your eyes, the screen is glorious.
I too don't believe the hardware to be the issue. I suspect it's more to do with having a device with a smallish screen and a large 1280x800 resolution. Higher res images and videos look amazing. If the image is quite compressed (i.e. lossy) then the higher resolution screen will show this more than a low resolution screen. Garbage in, garbage out comes to mind. We need all apps and videos and images to be high resolution 24bit minimum to make the most of our amazing screen .

Excellent. I will put it in a drawer for a year or so then. Hopefully by then there will be some video I can watch.

ha ha . Listen, think of it like this. You've probably got a high resolution monitor attached to your computer. Do you prefer watching videos at 420p and lower or 720p and higher? No doubt the answer is higher resolution to match your monitor.
What Samsung has done is squeeze in a screen with similar resolution to a 13" laptop, but in a 5.3" mobile device! So we're going to come across lots of images and videos aimed at 'normal' mobile devices, which won't look so great on our high-res screen. To make the most of the screen you can copy 720p or 1080p high profile videos to your sdcard, and they will look incredible on playback, but they will also be large and it's a slow process, and if the video is long then it'll also hit the limitation with FAT max file sizes. Those issues aren't the fault of the screen though. It's simple really. If you want to make the most of the screen density then you have to provide it with good quality source material suitable for a high resolution screen.
Do you think that its just software? No hardware? Do you think that ICS will fix this?
I came from dell streak and its realy hard to watch on note specialy on dark scene.
even opening xda app it has banding problems

It's definitely not a hardware issue because the screen is definitely 24bit colour. It displays well in the right app. You could swap apps for those that handle higher bit images. If you use Dolphin HD, possibly other browsers, webpages are seen in 24bit, if they are 24bit images. I don't know but there must be alternative picture viewing apps. Dice Player is a high res video viewer. As for system graphics, they don't look so bad to me. For games etc, it means living with banding until the maker upgrades? This is always the case on computers.
Be thankful Samsung have not rorted us.
Apple has ripped off it's customers many times selling lo-res screens as high res:
"Apple has received a new class action complaint alleging the MacBook
does not support millions of colors, but rather 16 bit color, which is
dithered to approximate millions of colors."

I don't have a Note yet, but can somebody try with QuickPic, it has an option in it's settings to force decode in 32bit mode.
That could clarify if it is a software or hardware problem...

The video and photographs shot with the phone's own camera have the same problems as other video and pictures. Surely they should display OK.
Some Android apps only render in 16bit

The phone has a 24bit 16 million colour display.
Some apps, including the picture viewing gallery app do not display 24bit colour in the 24bit quality they were made. See here
Thanks, Xaddict, this all makes sense regarding 24- versus 16-bit rendering.
Still, shouldn't intelligent/adaptive codecs be able to bridge the chasm by re-rendering 16-bit source material into some sort of "interleaved" or "inferred" gradual gradation or gradient... a codec to "smooth" the blend, if you will.
It's a codec issue, isn't it?
I wonder if Samsung or ICS will solve this first, if ever...
It feels like the Note has the same display like the first Desire (Amoled) that I've owned.
Its been said that this is a software problem, I've never seen this fixed with a 3rd party custom ROM since the Galaxy S1 days. Even 'x' ROM still shows color banding.
Found a solution for the wallpaper. Install MultiPicture live wallpaper (free from market) Go into it's settings and select "Color depth", then select "True color (24-bit). If the image you selected and used is 24bit, there will be no banding in your wallpaper. Hope this helped, cheers
Depending on the wallpaper you'ed still see massive banding.

It's not a software problem.
If anything, it's a low quality image being viewed on a 24bit screen problem.
I just received my Google Nexus 10 yesterday. After reading all the great reviews about the video quality I must admit I was shocked how poor it was. Don't get me wrong, it isn't awful by any stretch. The detail is certainly there and there is so much detail it might actually be detriment to the product because I can pick up compression artifacts and pixelization I didn't even know was there on some of my videos. However, this really leads in to what I think the source of the problem is on this device, that is, the black level. The first video I took a look at was Ice Age since it came with the N10. If black level is off on animations they can look washed out and it certainly did in this case. My projector on a 100" screen could actually reflect a better image in my opinion. Moving over to other videos like a 1080p MKV of Battleship displayed some improvement, but the poor black levels were still there. Oh, and I should mention this was with using MX Player.
So, are others seeing something similar? Again, I'm not trying to really downplay the image entirely because the detail is certainly there, but again, I'm disappointed by the black level. Is there possibly a way to adjust it that I'm not aware of? All I can seemingly find is Brightness and that doesn't do enough. Perhaps a gamma control would help? Any guidance from others is appreciated.
U get ice age free with N10?

Thanks for the welcome. Did people say the same about you when you had 2 posts? Trust me, your accusation is utterly ridiculous. This is simply my first Android device and this was my initial impression. I hoped that there might be some kind of workaround or fix so I simply did a Google search for a Nexus 10 forum and wound up here. As I allued to in my initial post there are plenty of things I like about the device and black level might not be a deal killer, but if there was a way to resolve it, why not pursue it?

Only 245 posts and a member since February of this year? You must clearly have very little to contribute anywhere since you don't have at least a 1k post count or year+ membership (sarcasm btw; post count and join dates means absolutely nothing in determining a person's status lol)
I believe a few others have mentioned black levels not being optimal on the N10. I myself don't really see it as a problem, but then again I rarely watch videos. I believe Contrast itself might be a better option to modify over Brightness, but I'm pretty sure Contrast isn't adjustable currently.
Possibly when Kernel development matures enough, we may be able to modify screen settings, but I don't think we're there quite yet. Maybe some video players might have an option for adjustments?
Those frequenting here have varying social skills. Be tolerant.
Suggest posting some pics of screen's black level, alongside another device used as a baseline. A thousand words and all that.
Also suggest searching Play store for "display settings" and try out the various widget/apps available.
That's seriously put me off buying this tablet now.
A poor black level can ruin video quality. I know this because my laptops black level is shocking bad, picture below.
Now I might either get a Note 10.1 or wait for something with a high res screen and a good black level.
Haha you guys are funny.
Anyway back to the original question, this device has a LCD screen, and like most LCD TVs, the black is not as black as you'd like or you would see on a PlasmaTV or Amoled screen.
If black levels are highly important to you, i'm sorry to say you bought the wrong device.
Ok, so I took a previous poster's advice and got a hold of an iPad3 with Retina Display and compared it against the N10. The difference was not as significant as I thought it might be. Ultimately, I didn't think either producing razor sharp images with inky blacks and that is because they don't my own HDTV's (LED) in my home along with my home theater projector crush both devices. Why? Well, first, I wasn't aware that the contrast ratio was so poor on all the tablet devices. Most of my other products have something like a 50,000:1 contrast ratio whereas the tablets are around 1000:1, a very big difference. Also, I'm accustomed to watching BluRays on those displays. BluRay quality just doesn't seem to exist on these tablets right now. So was I expecting too much from the N10? Yes.
Spending some time with both devices side-by-side allowed me to sort of critique both on my own terms and decide which one I like best. I'm probably an atypical user so my opinions here are my own and I don't expect others to find the same items valuable.
1. Display - the iPad wins here, but not by as much as I might have thought. Whites are more warm and not as bright on the N10 when compared to the iPad. Blacks are also better on the iPad, but I expected it to be a dramatic difference. It wasn't. I've included some images to this post that will help you see the difference a bit more. There are some images where the difference looks very pronounced, but that is the digital camera really exposing the faults of the N10 and making them appear more significant. I wouldn't say that is the case in reality. Also, something you'll notice from the images is the light leak. It is there on the N10, but not on the iPad. Too bad Samsung couldn't have done a better job here. It would have made it appear as a more quality product.
2. Form Factor - I find the form factor of the iPad better than the N10. I like to use portrait mode more often than most I think and the iPad gives you more space to work from horizontally when doing so. This makes web browsing much easier and I actually feel more cramped using the N10 to browse via landscape. I would MUCH prefer the N10 to have the iPad's shape.
3. Weight - I would have never thought 50 grams or whatever it is would make a difference, but to me it does and the N10 is a clear winner here. After handling both devices for some time I simply enjoyed holding the N10 more. The lightness made for a more enjoyable experience.
4. Rubber Backing - When I saw on this on the N10 I thought it was sort of a gimmick, but I really like it. Again, it just seems to feel more comfortable holding it.
5. Heat - I have no idea why, but the back of the iPad got pretty hot while using it. The N10 had some slight warmth, but ever since I've used it it has stayed relatively cool.
6. Speakers - The N10 really crushes the iPad here. The front two speakers are awesome and can push out good volume. Going back to the iPad with its rear mono speaker almost feels silly in comparison.
7. Web Browsing - The winner here is the iPad. Pages came up more quickly, they are easier to scroll through (only slightly), and are displayed better. In portrait mode the clear winner is the iPad since you have more horizontal space to work with, something I like.
8. Off-axis viewing - Not that you ever really need this because tablets are really made for a one person audience to be looking at the device head-on, but I did notice it. For whatever reason the iPad had a better image once you move off-axis from the device. The N10 was washed out more quickly as you moved off-axis.
9. Bugs - Oh man, Jelly Bean has them. I have essentially the base image on the N10 and I've already seen the battery information incorrect (stuck), freezes, my folders just disappearing after the device becoming frozen, and some other very quirky things. The iPad in comparison was stable. The iPad just feels a bit like driving a Lexus. It doesn't really do much to excite you, but it does what it is designed to do and does it well. The N10 is probably more like a BMW X6. Is it a sports car or an SUV? No one really knows. It does some things that are really neat, but in other categories it sort of falls apart. Just my own silly analogy.
So which will I keep. Based on all the criteria above I would say it is very close and probably a tie in my mind, but I'm leaning toward the N10. I'm not sure why, but I struggle a great deal with going to a closed environment like the iPad is. It feels boring to me and I just think I might enjoy tinkering with the N10 more. If I give it more thought I might change my mind, but for the moment this is where my head is.
I hope all this might help someone. If anyone has any questions about the comparison or the images please feel free to ask.
A lot people seem to crank the brightness even when they don't need it. The N10 with the back light turned up definitely has poor black levels but it's actually pretty decent when below 40%(more comfortable to view also)
I agree. I'm totally unimpressed by the video quality of Nexus 10. Maybe I'm doing something wrong here, but my older Galaxy Tab 2 P3100 had much better video quality than this. The colors are totally messed up and the it just seems bland and boring.
Frankly, I don't think this is an iPad killer in anyway, and I'm not an apple fanboy either. I had to download apps just to get the Volume to a reasonable level eventhough it has stereo. Wow, the ipad claims much less but delivers more, Nexus 10 claims tall but falls short.
Thinking about getting back the iPad 4 if the Nexus doesn't grow on me. Sorry, Nexus. Android has failed you :crying:

The 50,000:1 contrast ratio is actually dynamic contrast ratio. How dark the screen is at it's lowest brightness and how bright the screen is at it's highest brightness. It's really just a marketing gimmick.
The real static contrast ratio could be anywhere between 1000-5000:1. Not a huge difference at all.
http://www.dslreports.com/forum/remark,23137918
Looking at your screenshots I can definitely say you have the brightness set waaaayyy to high on the Nexus 10. Turn it down and the picture will be drastically better.
And for the other little problems you have to wait some time. Most of them will be gone with the first good custom roms/kernels. The device is still brand new.
I tried both the Transformers and Ice Age films streaming from google play, and I thought the video was pretty poor. Wifi signal was strong.
Video quality from all the streaming services I've used on Android have relatively poor quality. If you are attempting to benchmark the device's fidelity then I suggest making a high bit rate rip of a Blu-Ray
The high bit rate 1080p and 1440p videos I've seen look pretty great, but I agree videos from streaming services look pretty awful in terms of both blurriness and contrast.
Also, the hardware decoders like most devices do not have as high of picture quality as some software decoder. For instance, for the same video the hw decoder will look softer than the sw decoder in MX Player
1080p contend is supported more often from apps because of the amount of supported devices, I wondered if downscaling the tablet's screen resolution to 1080p is supported by any rom and if it would save a few hours of extra usage to the tablet?

I am no expert but I know that when you give the command to change the resolution it doesn't actually change it, it's more of a virtual/spoofing, to make the system think it's changed. So all the pixels will still be there. But when watching videos in 1080p the "upscaling" won't take much of your battery, if any at all. You won't notice it.
A digital screen only has 1 resolution. To use any alternate resolution it must be scaled to the screens native resolution so if you were to somehow force a resolution other then the native it would have to re-scale it to the native in order to display it which would require additional processing...
You could get better performance, in 3D applications for example but not better battery life.
I am asking for the SoC power consumption,logic says less effort saves more energy,current pixels to handle are about 4 million instead of the half that 1080p are
Though there might be needed optimizations as a modded kernel with different clock speeds

"Logic" that's ill-informed can be just as fallacious as a random guess. Your particular brand is working off of some very silly assumptions, and your second sentence really just highlights that. A modded kernel with different clock speeds? Please.
When you downscale an image, you have less pixels to handle only in the sense that the image becomes smaller. The actual display still requires that all of the physical pixels be addressed before it can display anything. The only reason that you see graphical performance improve in say, a computer video game when you're playing on a lower resolution is when the bottleneck is the graphics card rendering an image. If your computer is struggling with the output, then you have a different set of problems.
On a tablet, a game that's not built to the screen resolution (let's say it's designed for a 720p panel for the sake of argument) will keep load fairly light on the GPU for rendering, but the same amount of work as normal to display (although this is a simplification, it'll work for these purposes). That's because whether the content is 720p or 1080p doesn't matter-- the GPU still needs to figure out how to stretch it to the dimensions of the physical screen.
Bottom line, you're not going to save "a few hours" of usage. All the work you'd need to do normally will still be there, plus the chicanery of trying to transform all video output to 1080p again only for the physical screen to demand its normal resolution.
How do you explain the 3rd ipad (that your sighn shows you have) overheat from the SoC?The amount of retina display pixels caused it and overheat means power loss as far as I know.Anyway your ironic first setence made me loose any interest for rest of your post.

This! I know I was playing Dead trigger and you can enable the advanced graphics for tegra gpus, and it was laggy, but after reducing the resolution (the game doesn't allow this, or didn't the last time I played it) the game was buttery smooth.
And no, video decoding doesn't care what resolution your screen is. It still has to decode the whole video and display all the pixels, weather they are upscaled or not. your battery won't be affected by that. Apps on the other hand, like games, are another story.

Not sure what's worse, clueless people on a site called XDA-Developers or clueless people who refuse to listen to advice.
Whether the iPad has some kind of overheating issue is a completely different matter and can be caused by a number of things. The fact is that changing your screen's render resolution has almost no impact on your battery life. The GPU still has to upscale whatever is rendered to the Nexus 10's native resolution. The biggest drain on the battery is the display itself; it takes a lot of energy to light up a display with such a high pixel density and still be bright enough to see.
Irony is the worst of all,at least some people know what a question is as this thread is
When you ask a question you need to be able to accept an answer that isn't on your liking. You've had 5 people telling you in different ways that it won't help, if you don't want to believe us, then here you go this doesn't work on 4.3, just 4.2 and maybe earlier. You can change it and use it for a week and see for yourself. Just make sure you don't let autosuggestion cloud your judgement.

Ahaha, says the new member who has demonstrated 1) that they don't know what irony is, and 2) that they have no idea how to ask for help. Hint: it's not "please validate my preconceptions." The only irony here is your reactions to the thread that you spawned.
My iPad has never overheated, or even come close, really. It's the same crowd of people who will complain any device "overheats" when they're doing something that is going to create thermal load. Newsflash: that will be just about any game or long-term video ever. The 1080p Nexus 7 gets warm under use as well-- oh wait, 1080p is some magical resolution that will fix all your woes, right?
Protip: overheating doesn't mean power loss unless your circuitry gets pushed outside of standard operating conditions and loses conductivity due to thermal deformation. On a desktop PC, it might mean power loss from running the fans up, but as mobile SoCs use passive dissipation, this is a non-starter. Heat buildup is a byproduct of using a processor to do things.
I hear they lower the res from 1440 to 1080 in the G3 so is there a way to lower the screen resolution in the G2 from 1080p to 720p?
I couldn't find anything about it in search.
Screen resolution of an lCD is a physical attribute, it cannot be changed. You can change the software to renderer the image so you would get a lower resolution data to show, and since android source is available, it is technically possible. I doubt anybody tried, because our device has a adequite computing power to generate 1080p images. On the other hand, lg g3 has almost same power, but it displays almost double size image. For g2, it won't worth the lost of quality.
The issue is, since LCD will display it on its physical resolution(there is no other way), your image quality will be far worse than the down sampled version. For example, if you render the sceen at 720p, and show it on a 720p 5.2" display, you will lose ~%55 of your data, but since you render your source on this resolution, will be sharp, just won't have so much detail. If you display this 720p image in 1080p display however, screen resolution cannot be changed, so your screen will try to calculate the missing %55, and then show you the result. Since there is no original data, it assumes the missing pixels were like the ones around them, which means your result will be blurry.
As a side note, old tube displays does not have a resolution, they can support various resolutions. We used to set resolution to our taste between speed and detail back then.
enigmanp covered the technical aspect of it and I'll just follow up with my own personal experience.
I had a chinese android tablet running at 2048x1536 resolution, the same resolution commonly found in iPad tablets.
My Android tablet sometimes perform sluggish because of the high resolution. Even though the CPU was a quad core 1Ghz, it's still chinese and the GPU wasn't great either. So I lowered the resolution and everything was blurred and not sharp at all (due to the reasons enigmamp explained above). I DID notice an improvement in overall speed, but apps started misbehaving and it was all a huge mess.
Now the only reason I did that was because I found my tablet lacking smoothness/performance. I just don't quite see why you'd want to do that on the G2 since the CPU and GPU can clearly handle even the most intensive 3D games on high detail. Could you please explain?

So why it doesn't get blurry on the G3 then?
If it's to save battery, I doubt you'll see much of a change.
The GPU is working on a smaller load but most of the time it's running at 200 MHz anyway. But I'm no expert, I'm just telling what I know and what I've experienced. I'll head over to the g3 thread to read more!
Reducing the number of pixels would help you to save battery if you are using a phone with AMOLED screen, sadly it is not the case with LG G2. So even by turning the resolution down, you are using pretty much the same amount of battery as you would with full 1080p resolution.
If you want to go ahead with it anyway, there are plenty of apps on the play store which does this. Just search "resolution" in the play store and you'll find them. However I don't think this will help your battery life at all, nor do I recommend it.
Late addition
Well, when i found out this was an option i just had to tinker. I have a G2 that is my daily driver and a S6 for back up. I changed it to 900x1600 480dpi and it works just fine. The camera touch focus is a little off, but otherwise it is sooper smooth now. I also throttle the CPU down. So both together I get a good experience and decent battery life. I know this is a late response, but to anyone out there with root and some lackluster performance might want to give this a shot. I needed to reboot once to correct some keyboard skewing. I also adjusted the height of the keyboard to compensate for the change in real estate. Works like a champ, no real noticeable degradation in viewing pics or videos. I'm going to try this on my Nook Hd+. It needs a shot in the arm (no pun intended).

Well, when i found out this was an option i just had to tinker. I have a G2 that is my daily driver and a S6 for back up. I changed it to 900x1600 480dpi and it works just fine. The camera touch focus is a little off, but otherwise it is sooper smooth now. I also throttle the CPU down. So both together I get a good experience and decent battery life. I know this is a late response, but to anyone out there with root and some lackluster performance might want to give this a shot. I needed to reboot once to correct some keyboard skewing. I also adjusted the height of the keyboard to compensate for the change in real estate. Works like a champ, no real noticeable degradation in viewing pics or videos.

it would be nice if you share a "how to" as well
i tried lowering the resolution on my tablet and G2 with some apps from the playstore - but only thing i got was an unstable device(s)...
desertmod1 said:
I hear they lower the res from 1440 to 1080 in the G3 so is there a way to lower the screen resolution in the G2 from 1080p to 720p?
I couldn't find anything about it in search.

download terminal
write in terminal :
su [ENTER]
wm size 720x1280 && wm density 220 [ENTER]
new density: new resolution * current dpi / old resolution ( for e.g. 720*1280*480/(1080*1920) = 213), altough i tested, and it seems that 240 is the best (for me), but it looks awful, for me, so i will go back to full hd + 410 dpi
ofc root required )
anyway, please share with us if it will be any battery life improvement

As a side note, old tube displays does not have a resolution, they can support various resolutions. We used to set resolution to our taste between speed and detail back then.

Now I miss those glory days of correcting CRT display alignment and freedom to changes aspect ratio/resolution beyond the DAC supported rate at the expense of mild irreversible eye's retina damage. Lol. :laugh:
In case you haven't read it today, Netflix is now supporting HDR for our XZP's - see Android Police and or Android Authority's articles.
Does anyone know if 4k is also now activated on netflix for the XZP or is it just hdr?

4K has been available on the Netflix app for a long time. HDR was the only thing that was missing (which has now been added)

I do not believe this is correct. Do you have a source?

What do you think is incorrect? I just finished watching an episode of Daredevil on Netflix in HDR. I didn't see anything in 4K though, but it might be that my preferred series do no come in 4K.

I was trying to be polite by saying I did not believe that's correct. Netflix's android app does not currently support 4k Playback on any phone. This is a demonstrable fact, it's nothing to do with your preferred series unfortunately.

My ability to use Google is just fine thank you, as is my ability to read/comprehend: The article you linked only mentions HDR support not 4k support for Netflix because unfortunately Netflix does not support 4k Playback for android phones.

No 4K is a shame. I was afraid that this is what you meant. I was hoping though that you meant that there was no HDR content. In any case, there is hope. Especially since the stopped allowing their android app to be installed on a rooted phone. So they might get ready to bring some really high quality content to the phones.
It really doesn't matter anyway. Unless you put the phone within 3 inches of your eyeballs you won't see the improvement in detail over 1080p.
Physically impossible,
HDR on the other hand and high bit rate low compression will and does deliver significant improvments

It actually is possible.
I downloaded the Peru 8k video in both 1080p and 2160p. While both of them look really nice, I can see more detail in the 2160p one.
It's not like I can see individual pixels, but more like having a brand new prescription compared to my old one. Both let me see pretty clearly, but one is perceptibly clearer.

My reply didn't last for some reason an I can't be bothered to type it all out again just now but to summarise.
Physics doesn't lie, with normal eye sight on a screen 5.5 in with, 2160 resolution, the range in which you can detect those details, is 3in, beyond that, a typical person can't see those details on such a high PPI screen.
Monitors have a significantly lower PPI so will have a wider range.
To see 4k Improvements on a large TV you need to be within 3 foot. Far beyond what most people have in their living room. But is exactly the maximum distance you will find in any TV shop
What does make a difference is bitrate, HDR, compression artifacts, Contrast ratio, saturation and brightness.
And typically its that that will improve a pictures appearance.
4k alone, physically can't be detected.
It's the new 3D, Designed to fill a marketing departments wet dreams.

First mistake is using the term "normal", it should be average. The difference is normal implies what everybody sees, where as average indicates that there is a sliding scale and some see better than others. And just that, not all visual acuity is the same, some are slightly better, some are dramatically better. This applies to a wide variety of factors as well, not just detail.
Second mistake is in assuming the ability to pick out "detail" is the end all be all. The ability to pick out specific details in a static image (say the corner of a building) may in fact be driven by physics (again, using "average" eyesight) however that does not directly correlate into video with moving edges, edge sharpening and pixel bleeding. Just as the ability to pick out detail can be averaged, indicating higher and lower levels of eyesight, sensitivity to motion detection and color balance are also can be judged on a scale. What this says is that the edge of a bright colored building as it moves against the background may have much more than just "detail" to those with heightened visual acuity.
firstly Normal is the perfect description for eye sight that is considered to be optimum, any deviation from that is sub optimal so when one talks about Normal, IE, what is considered perfect, eye sight, that may or may not be the average, but I couldn't give a monkeys about average eyesight, we are talking about the physical limitations of the human eye in a perfect environment.
Secondly, a moving image is even less likely to have higher visible detail. If you are sitting 6 inches away from our tiny 4k screens, the physical limitation of you eye prohibits you from being able to see the individual pixels, you cant see it, in the same way you can see the flag on the moon, even with the most powerful telescopes on earth or even in space, Hubble for instance cant see anything much smaller than a football pitch and yet it can see whole galaxies in what appears to be highly detailed images. your eye can also only see detail in a relatively small portion of your field of view anyway, our eyes are comparatively crap compared to other animals but they are very good multi functional eyes, more of a jack of all trades, master of none.
anyhow, thirdly, you will notice that I did say that the higher bitrate associated with 4K HDR videos along with much better compression algorithms do make a noticeable difference in image quality, which is what you are talking about when talking about colours, contrasts and motion. Its not the 4K that's doing that, its all the goodness that comes with it.
I have this phone, I have several 4K screens of multiple sizes and I can tell you that 4K isn't the be all and end all especially if you sit beyond the optimal distance, if it wasn't for HDR being packaged with 4K it wouldn't be anywhere near as successful as it is. HDR on a OLED is breath taking, hell, even on a decent LCD/LED screen it blows FHD screens out of the water. of course you need a decent HDR TV for that, one that can pump out 1000+ nits.
