What Samsung means when they said 'HDR'

In the Unpack event presentation they said it's an HDR like you never seen before, is that mean 10 or 12 bit display that must be used with content and apps that support HDR profile (example HDR10 Media Profile) or is it some kind of post processing that play with gamma profile dynamically?
If someone know the exact technical information, please share it.

I think this article may answer your question.
TL;DR - (from article) - "...HDR requires a screen capable of exhibiting brighter whites and deeper blacks than a standard screen is capable. In televisions there are differing levels of HDR ability, with Samsung's SUHD panels, such as that of the KS9500, offering greater-than 1,000-nits output (that's the measure of maximum brightness). In the case of the Samsung Galaxy Note 7, which uses a Super-AMOLED screen, it's capable of 800-nits at its brightest. As this is an OLED panel, however, that level of brightness is still considered to be a premium grade....."

EDIT: To answer your second question - It appears, per the article that it IS in fact dependent on the content / application as well. In other words - Its NOT always on.

Ok found it, this article explain it a litter more in detail.
As I understand it the display have a bit depth of 10-bits that support Rec. 2020 color space through HDR10 media profile, and it's driven by DNIe processing chips on the hardware side.
Thus only videos encoded in HDR10 profile and played using a video player that support HDR10 will be in HDR.
Netflix and Amazon Prime among the early adopters.

Clarity/resolution

The Sony Xperia XZ Premium has a crazy crisp display. Just kidding, this is automated text so who knows if this screen is any good. So, you be the judge! A higher rating indicates that it's extremely sharp and clear, and that you cannot see pixels with your naked eye.
Then, drop a comment if you have anything to add!

I do see pixels
We all do cuz of the pixel pattern...
Screen isnt as crisp as i expected in a 4k display, id say its as good as standard 1080 screen... Not even a good 1080 xD
When virtually emulated to 4k its better, its still on a 1080p level though thats how my eye sees it at least
Im only talking in terms of sharpness, i expected more details on a 4k display.
In terms of colors, brightness, id give it a superb level as it is very natural and realistic! Not like fake amoled crap, but super natural and its like looking out a window, yet i expected a sharper display concidering the 4k display

The screen is really crisp, at least through vr. When I use VR, I can see the pixels but they don't look huge like on 2k phones.

Have you ever try to change it's default resolution to 4k with 720-821 ppi density via adb command?
If you looking for "crisp", already try it and still say "isn't crisp as I expected", then i can't say anything anymore.
For my eyes, when try to change it's default res to 4k, in terms of crisp and sharp it's the top of the top of crazy display i've ever see. I've never see for real 8k display monitor yet, but I can say panel on this phone is really insane. You can directly compared with any phones in the world right now with that configuration (4k default res), and it's a champ! Yes, there 'unpleasant' bug layout for some apps because they aren't reach yet to develop on 4k native resolution. And the most important, the black recent apps fault lol. So I am not use that config for daily usage.
But if you just curious to see how the real performance of this phone screen, then that config is worth to try.
I've not said about 4k HDR content, there some example files you can download to see 'beyond the limit performance' of this phone. It's super crazy sharp and crisp with insane range of colour!
Instead, in terms of detail, i can't barely say it will fulfil your expectation, because for me it's hard to expect level of detail on small size display.

OMG finally someone on the internet sharing a same frustration as me. I wonder if there's any workaround for the black recent apps view glitch when running higher than physical resolution? It almost feels like a internal scaling issue where if I put the phone into landscape I can see partial app snapshot being visible in recent view. This is so far the only issue holding me off from using QHD or even UHD on a daily basis.

yes I can see now on 4k mod its insane but I can still see pixels, the phone sharpness look insane! but seeing pixels is kind of a draw back i mean the phone's crispness is on another level with 4k mod but why see pixels?

Hangon, keep in mind there are high density dots on the screen, these are not pixels. I'm sure these dots are from the manufacturing process of the phone.
I bet you actually can't see the pixels but are mistaking them for these dots scattered on the screen. The display, which is 3840×2160, is bellow the screen which has dots at a dpi (dots per inch) of around 200.
After a while these dots disappear

Question before buying - any black bar when playing video?

I have a oneplus 3 phone. Very happy with it, it's just I want to upgrade to a bezel less phone.
I wonder, for xiaomi mix 2 video playback, will there be 100% full screen or there will be two black bars on the left and right edges?
please advise.

Whatever you want, but what do you want
Before anything else, I think you need to realize that if you get a bezeless phone, you are going to have viewing differences then phones with a bezel, as it's a wider viewing area then the ratio most phones take video in (explained in more detail below). However, that does not mean it's changing the video from the way it's currently captured on your bezeled phone to the way it would be captured on a bezeless phone. The only thing that impacts the video capture is hardware such as the camera, megapixels of the camera and recording resolution or in terms of viewing, screen resolution and dpi. Therefore, that is probably what you should make any phone buying decisions based off of and you can use a handy website like gsmarena..com to get full specs on phones from all around the world in addition to a bunch of other useful tools like size comparisons.
With that said, if all your concerned with is cosmetics, then the Mi Mix 2 still has you covered as you literally get a button that says fullscreen. Tap it on, the video stretches to fill the screen, tap it off, it retains its proper ratio in letterbox (black bars). As that feature demonstrates though it's purely for looks, which is why I would caution you from making any decisions based off of it. It's like deciding whether a phone is right for you based on a phone case, which has nothing to do with the fact that your buying a pocket computer and ignores what it's used for or in your case what size pictures/video you want. The Mi Mix 2 takes video in 4k, 3840x2160 at it's highest resolution, that is a 16:9 ratio. Phone sizes are not typically made in 16:9 ratios, they are wider, but 16:9 is the most common ratio used across the entertainment industry from video distributed in movie theaters, TV, YouTube, to video being captured on most phones.. Consequently, any bezeless phone will have a wider viewing area then the video they capture in 16:9, yielding black bars.. However, does that matter? Have you ever decided on buying a computer based on whether you have black bars when watching YouTube in fullscreen, probably not, and most likely you do have black bars at the top and bottom of videos because computers tend to use more square ratios. Therefore, regardless of any cosmetic differences, which can be achieved by stretching a video to fill the screen (a technique often used when broadcasting non standard ratios on TV and even a setting you can trigger on most TVs through the display menu), the Mi Mix 2 captures video in the most widely used and distributed ratio of 16:9. Therefore, if you watch your recorded videos on most TVs, it will fill the entire screen and since the Mi Mix 2 shoots in 4k UHD, the resolution will be pretty good too.
Hope that helps. I own a Mi Mix 2 and honestly it's a fantastic phone all around, although the explanation above is really for any bezeless phone and for anyone making decisions in a similar fashion. Essentially you should decide what you need out of a phone first then judge how things look, which will help inform why they look that way and how much weight you should afford to any cosmetic aspect. I also work in the film industry and realize most people don't know or necessarily pay attention to things like video ratios, so I'm happy to share, but as mentioned above, regardless of your knowledge, you should not take for granted the fact that phones nowadays are massively powerful pocket computers capable of incredible things and instead reduce them to "black bars".

advantage of using 4K screen resolution on Note 10 plus?

Hi guys,well I want to ask you smart question and I really don't know the answer.
I got myself used Note 10 plus and because of the battery issue I switched to 1080p resolution to save some battery.
Then I opened some webpage like lets say webcam site chaturbate.
From what I know on monitors,higher resolution on monitor gives more web content on screen,so on my 1440p monitor I can see more webcam models on screen compared to 1080p monitor.
I thought then it's the same with phone screens,increasing resolution to 4K,I'll see more webcam models then 2 cams per line which was not the case,switching screen to 4K I haven't seen any difference.
So is it suppose to be like that,or I'm missunderstanding something here?
Why won't it work like on PC monitors/screen?
How can we take advantage of 4K on phones,in my case on Note 10 plus?
Does it have advantage switching to 4K when viewing websites,besides videos ofc?
Even when watching videos I doubt anyone (any human eye) will notice difference on 6.8 " screen with 1080p vs 4K on Note 10 plus.

"4K" or WQHD+ on the note does not really relate to extra space on the screen like computer monitors. as the computer monitor scale back the size of the Icons and increase perceived desk space (depending on monitor size and max resolution capabilities) as the UI on smartphones must be readable the gain is barely perceivable. You can adjust the size of the icon to make it look like you gained some space but it wouldn't be accurate.
The real difference and depending on you, you may or may not perceive it, is on the pixel density.
In 1080p the Note has a certain pixel density, when you shift to "4K", you have a higher count of stacked pixel density. It looks better with some content that supports it but its sort of a cheat. The screen is not actually 4K, kind of like the 7nm vs 10 nm wafers in Intel Vs TSMC foundries. TSMC says it's 7 nanometers and intel 10, but they pack around the same transistor density, the names are mostly marketing.
You wont notice a big, if any, difference due to our own limitations (eysight), you can get a better picture of the issue looking up (Googling) "Full HD vs Quad HD" from the Oled Association.
They break it down a bit ...

Oh okay.Thank you for kind explanation.

Doesn't seem to use any or just slightly more battery so I guess I'll sample it a while.
Forgot about the WQHD setting.
The 10+ still has one of the best displays. Lots of issues with the high refresh rate displays it seems.

Well, I barely notice a very little difference, very little indeed, and, mostly when viewing photos or videos taken with the best resolutions, for everything else, all look just the same

Went back to FHD. WQHD uses more battery (probably about 1%@hr more) and didn't make a difference I noticed doing what I normally do.
It's cool that it's there like many of the other 10+ options.
I have 20/10 vision.

Question 4k video worth it over 1080p?

I have been doing some video recordings today and noticed how large the 4k 60fps videos are (about twice as larger as 1080p 60fps recordings).
So I went ahead and did some 1080p recording to compare 4k and 1080p on my 4k LG CX TV.
Tbh, I didn't notice much of a difference.
So I am really wondering if 4k is even worth it considering its file size?

It mostly just depends on the camera used. I guess you used your phone to record. right? Most phones can't do 4K properly, it's just a feature they advertise. If to you 1080p looks fine, I don't see why you would bother with 4K60. Or maybe just try 4K30, in some cases it does end up looking better than 4K60.

i mean twice the size for 4X the resolution is worth it
you need to take into account the finer details and edging in 4K which will show better results.
also most smart tvs including the CX have resolution scaling and other filters to make lower res content look better on 4K panels
also dont forget thats an Oled tv thats gonna look great with whatever you pump into it

Ye but if most TV's (or small screens like our smartphones, or any 1080p screen) won't really show a difference in quality, why even bother with the bigger file size. No one will realistically notice? :S

One advantage would be that you could theoretically crop or zoom the video and still retain acceptable quality on most resolutions on screens. Just like you said, it won't make a big difference on standard FHD displays however it would be noticeable when the video is cropped or zoomed.

i mean by that logic why watch 4k and get 4k tvs in first place. why have a higher res screen.
I mean why get the pro should have got the 1080p panel 6
Theres a lot of content 4K video will shine
even 4k video downsampled to 1080p retains better details than 1080p does.
Sure on a phone screen you wont see the difference but on a tv thats 55inch or higher the gap is noticeably wider its a major difference.
There will be parts you notice also more so. take into the account if you want to focus on specific parts of a video or edit / crop edit
also your content is future proofed
open all the images in seperate tabs to see full resolution.
the latter 2 are 50% res of the original screencaps you can easily see the details are maintained scaled down

Real 4k movie content does look surely better on my 4k TV compared to a 1080p TV / content.
But that is real 4k movie material and not google pixel 6 pro 4k video content.
Are your screencaps from recordings done with the google pixel 6 pro?
Because I am talking only about the P6P recordings, not about anything recorder with smth else.

no they were not but the point still stands it was just a prime example
regardless i literally did test videos of still objects in my spare room with text from a distance.
in poor lighting conditions its literally dark and the bulbs ****
literally even look at the portrait still in gallery before you even play the video you could see the text on objects was actually legible and also sharper
if you fail to even notice the difference between 1080 and 4k on your tv you may need your eyes checked.
dont forget theres literally rated seating distances for screen sizes, distant seated and also resolurion of display
the closer you are the better the fine details you see
did you stand up and look or did you sit down and look so you basically looking at like a 20inch display
Sounds like you putting the LG CX to waste
it was the exaxt same situation with people when hd 720p and 1080p came out they coudnt tell difference from sd
also people who think FHD and 4K dont make a difference are the type of people who think you can see above 60fps.
One of these is 4k downscaled the other is 1080p downscaled both also limited to poor lighting conditions

Okay, then again: This is specific to the google pixel 6 pro.
Yes there is a difference between 4k and 1080p.
Yes there is a difference between 30hz,60hz,120hz.
But it also depends on the source equipment and how it is recorded.
I can use a **** camera to record a video in 4k but it won't look any better than 1080p due the camera being so bad. And this is exactly why I am asking this in regards to the google pixel 6 pro.
How good is the camera in videos really and how big is the difference with it in 4k vs 1080p.
Thanks, I know how to setup my TV. And due to my job I have to test my eyes every year.. still getting highest results :>
But if you can see a difference in the thumbnail of your image gallery, then the placebo is really strong with you.

Most people who cannot notice a difference either have reduced vision or use a small monitor. I dare everyone that can't make out a difference between 1080p and 4k source material to use a Monitor 40" or bigger. On my LG CX (48") that I use as a monitor the difference is night and day.
It should be noted, though, that the difference is rather minor when video footage has been shot by phones - their sensors are just too small to make out the minute differences, plus they can't take in enough light. If you compare professional video material shot by expensive dedicated gear in 1080p vs 2160p, the difference is HUGE, whilst smartphone camera footage isn't that "obvious".

At the end of the day it's what works for a given person. If 1080p video works then that's a great option, if 4k works then that's a great option.
If the 4k video is really only twice the size then it's because they're being more aggressive in compression. There's no magic bullet to squeeze 4x the data into 2x the space other than throwing data out.
Tangentially related - GoPro's 8/9 and probably 10 set (i.e. limit) the recorded video to 100mbs for higher resolutions. Ergo you get higher quality (less compression) with 4k24 versus 4k30 versus 4k60 because they're all recorded at the same bit rate.
The P6P may have throughput issues that limits just how fast they can write data that results in higher compression in order to reduce the file size at higher resolutions. Or it could be design choice to reduce file use since the most common ones are likely the 128gb versions.
In this case, specifically with the P6P's, the actual end result is that 1080P might be nearly as good as 4K if they're cranking the compression up and loosing the details that are the point of recording in 4k. So bottom line the OP could have a pretty solid case.
I should get mine tomorrow and the holiday coming up should make for some interesting testing.

At the end of the day it's what works for a given person. If 1080p video works then that's a great option, if 4k works then that's a great option.
If the 4k video is really only twice the size then it's because they're being more aggressive in compression. There's no magic bullet to squeeze 4x the data into 2x the space other than throwing data out.
Tangentially related - GoPro's 8/9 and probably 10 set (i.e. limit) the recorded video to 100mbs for higher resolutions. Ergo you get higher quality (less compression) with 4k24 versus 4k30 versus 4k60 because they're all recorded at the same bit rate.
The P6P may have throughput issues that limits just how fast they can write data that results in higher compression in order to reduce the file size at higher resolutions. Or it could be design choice to reduce file use since the most common ones are likely the 128gb versions.
In this case, specifically with the P6P's, the actual end result is that 1080P might be nearly as good as 4K if they're cranking the compression up and loosing the details that are the point of recording in 4k. So bottom line the OP could have a pretty solid case.

1080p30 is 19.8mb/s at 1080p
4k30 is 42.8mbps
1080p60 is 24mb/s
4k60 is 62mb/s
this was at h265
4k30 h264 is only 48mb/s
4k60 h264 is only 72mb/s
h265 uses a main profile @ 6.1
h264 used a high profile
4k60h265 is only 45.2mbs on my galaxy note 9

For me, the question is do you need 60 FPS over 30 FPS? I do 4K because I want the highest resolution I can get but I do 30 FPS because I don't need that smooth look.

That's interesting that the bitrates are on the lower, half the bitrate for 4K30 for example compared to any GP in the last few years. Is this user adjustable is a question.
I'm getting the P6P 512 with the hope that I can ditch the GP's I usually carry. I record VLOG footage during my ultra runs and I carry a phone with me regardless. One less device and its accessories to deal with would be great.
I have a selection of video recorded with my GP 8 and 9's, I can run the same run/route in the same resolution and do an apples to apples comparison of quality. It'll be interesting if nothing else to compare the stabilization quality of each. Hmm, I think I can probably mount both the phone and a GP to the same stick and get direct side by side as well. The wheels are spinning now on how best to compare the final product of each for my needs.

could be a heavier encoding profile than standard go pros that and action cams in general usually have a large amount of motion so bitrate is needed to compensate and gopros are generally used professionally so editing etc needs that kind of headroom
my akaso v50x uses the same bitrate roughly at 4k30 as the pixel but is perfectly fine in daytime except its cheapness shows in low light performance
