[Q] Screen size in 16:9? - Samsung Galaxy Note 9 Questions & Answers

Did someone make the calculation for the actual screen size, when watching 16:9 content?
If it is at least around 5.7" I will update finally my beloved Note 5 !!!

How do we rank in screen Res??

How does the Jewel match up to other contenders in terms of Display?
All I know the screen on the Gem is looking GREAT!!
Anyone?
AFAIK 480x640 is the highest res available on a phone.

Actually look at my signature - I had a Toshiba Portege G900 about a year ago and it had an 800x480 display and it was just 3 inches. So info is not accurate. It also had a slide out keyboard fingerprint authentication and was kinda ugly but the display was breathtaking... Sony Xperia will also use the same display!

Some screen shots of such device I must see
Pic please!!
800x480 is kind of pointless.
The Diamond's 640x480 at 2.8 inch display equals 286 ppi. The naked human eye can't distinguish details beyond 250-300 ppi.
Should you have a higher resolution, you would need a magnifying glass to notice it. Hence a higher resolution on a display of that size is a waste of pixels.

I see your point - but I am designer and have been for 10 years and can easily tell the difference between 600 DPI and and 300DPI and that is also for PPI - as far as the display on the Portege is concerned it was by far the sharpest and best display I have used on any device also it was true widescreen so the extra pixels where definitely not a waste.
Put it this way a website when scaled down in say Opera will look noticeably better on the 800x480 screen than it would 640x480 and thats fact, when it comes to fonts as long as you have good eyesight there are far more readable smaller in that res. Also you can have a higher PPI setting for the overall OS allowing more info to be displayed on a today screen - but for that you need good eyes lol

Well, there is a significant difference between PPI and DPI. In the case of DPI it's actual dots surrounded by white areas (if the paper is white). Pixels on the other hand, when back-lighted provide optically more of a gradient. As a result you can spot difference in details somewhere between 500-600 dpi, while the limit for PPI is about 300. Of course it depends on the distance at which you are looking and how good your sight is.
The 800x640 on a 3 inch screen gives sqrt(800^2+480^2)/3 =~311 PPI while the Diamond's screen is sqrt(640^2+480^2)/2.8 =~286 PPI. So they are both in the 300 dpi ballpark.
As for the extra pixels on the Protege - well, of course - it has a bigger screen and extra screen space is always valuable, there's no denying that.
My point was simply that for a screen size like the Diamond's there is little use in significantly increasing the resolution - the human eye simply can't see the difference. If you have a larger screen, then of course you'll need higher resolution to get the same PPI. (Standard computer TFTs are by the way usually in the 80-100 PPI range).
Cool.
I put the Diamond next to its biggest contenders.
Fruitphone, BB Bold First in the world to have it in Chile!!!, Nokia 95 8gb. etcc..
All the mentioned above had a crappy screen compared to the Diamond on full brightness.
All the contenders ran away with there tails in between their legs
So yes simply with the naked eye you can really tell the difference between the high res we have on the Jewel.

[Q] iPhone 4 vs Note Display (Do I have a bad Note?)

Hey Guys,
It has been two months since I switched from my iPhone 4 to the Galaxy Note and I haven't touched the iPhone since I bought the Note until yesterday to factory reset it and give it to a friend when I noticed that the iPhone's display looked better (higher resolution) than the galaxy note!! I felt that my Note has a bluish tone to its display?!?! Is this normal or do I have a faulty note? Please help!!
The iPhone 4 has a higher PPI (Pixels Per Inch), so the iPhone's screen is sharper. But the Note's screen is far from bad. Can you post a pic of your screen? (Not a screenshot) And try to get a good pic.
I am at work right now. Will post pics of the Note once I get back home (Can't post pics of iPhone and Note together cos I gave the iPhone away). I am not saying that the Note's display was bad but when I placed them side by side I could tell that the iPhone's display was better easily. I thought the Note should beat the iPhone in display easily because of the Note's higher resolution.

iPhone 4 (and 4s) has smaller screen, but higher resolution: 3.5 inches 960 × 640 px at 326 ppi. So it's screen shows more detail than the one on the Note.
I played with iPhone 4s and the Note side by side and would agree that movies, for example, often look "better" on the iPhone, especially the darker sciens. Although the overall picture is smaller, the iPhone's super LCD screen tends to give "more natural" look to a video than the super AMOLED screen on the Note, especially if the quality of the video encoding is not that great. In my experience anyway...
That being said, the quality of screens on the Note appears to vary quite a bit. There's a couple of rather long and active threads here discussing the screen issues...

Nexus 5 screen size, real estate, and battery

The Nexus 5 looks and runs great, but everything's so big I feel like I'm using a toy phone. The PPI really would have made more sense on a 4.5/4.7" screen (or even a 4" screen for us small-handed), and for a budget phone I would have expected 720p (pixels) resolution. This would use less battery which would require less battery so it could have kept about the same thinness (but I'm perfectly happy adding thickness and heft for more battery).
I don't understand Google's thinking behind this phone. It's a great-quality phone, but it's just too big for the things on the screen. They look great about 10 inches away but normal distance from my face, about 7", everything just looks oversized. I feel like at this screen size they could have added another column or row to the launcher and had them match up to the bottom dock shortcuts.
I know how to change the PPI, but I would just more like to know what made Google decide to go with such huge icons and fonts on such a large screen with full HD (1080p) resolution and not add any more real estate to things like Chrome or Settings or anything.

You don't change the PPI, you change the density lol
The Nexus 5 isn't really meant to be as much of a "budget phone" as it is a "developer device" (officially for AOSP, and unofficially on here) or "reference device for other OEMs", hence why it has a 1080p display and a Qualcomm Snapdragon 800. It just happens to be cheaper as they also cut some corners (and probably to make it burn a smaller hole in developer's wallets).
Anyways, nothing looks "oversized" without changing the density. Most (if not, then all) Android devices have the density set relative to the resolution (NOT physical screen size nor pixels per inch) as well as what sort of device it is (phone or tablet). It's a standard, not "whatever the OEM wants", if an OEM wants something to appear smaller or larger in their bloated system apps, they're going to modify the app itself, not change the density (which affects ALL apps rather than just the intended). I also have a Note 3 (which I never use and just gathers dust), it's the same resolution but much larger, and the stock density on that is also set to 480 (same as the Nexus 5). I also know that the HTC One (M8) and OnePlus One are also set to 480. Just about ANY Android phone with a 1080p display uses 480 (stock, at least), I don't know of one that doesn't.

Nova Launcher is the solution
I liked more the Galaxy Nexus size. Based on my experience "width" is what matters for one-handed phones.
However....5" is not bad. The only f***** thing here is the resolution. 1080p is a waste for a simple 5" screen.
It must be something slightly bigger than 720 without jumping to 1080.

1080 isn't a waste at all. Its HD. If it makes sense on a 32" TV several feet away, it makes sense on a 5".screen several inches away. Its called "viewing distance".
Choosing some arbitrary resolution between 720 and 1080 is a silly idea. These resolutions are a global standard and media content is created to these standards. Choosing something win between would mean no content was optimised for our display so something would be lost in the downscaling or upscaling.
1080p is perfect for the distance you view it. If you sit 1 metre away from a 50" 1080p TV, it won't look HD. It will look lower blocky. That is because the pixels are literally bigger than a 32" TV of the same resolution. Its designed to be viewed from further away. As you move the TV further away, the image gets clearer as the pixels appear smaller.
All PPI is about is measuring the amount of pixels in an inch. This is a fixed value. A 1080 screen always has the same amount of pixels. This means the pixels are bigger on a bigger screen, so the PPI decreases. The smaller the PPI is, the further away you would expect to view it from.
1080p on a 5" screen would be ridiculous if the device was intended to be used at over 1 metre away though. Because that is beyond the optimum viewing distance. It would mean that the image again lost detail.
I think 2k and 4k on this size screen is over kill. But that's not because of these reasons. We would definitely notice a sharper image on the display. The problem is that there is a massive performance hit. The GPU works harder meaning its slower than it would be on a lower resolution. It uses battery because of this.since there is very little content, its not a worthwhile trade off at this time.
That said though, visually it would look better. The screen may need to be 6" to really get the benefit though. Otherwise the PPI would be too high for the viewing distance and your need to move the display closer than the screen closer than the usual distance to get the full effect
DPI is something entirely different. That's what causes the assets on screen (buttons, icons etc) to appear bigger or smaller.

Yeah I know all that. Just saying...1080 is a waste for a 5". A waste of GPU and resources.
We don't really need more than 330ppi on a Phone....

Your first sentence directly contradicts your last sentence. If you understood optimal viewing distances you would know that we do need a higher PPI. Why should we be restricted to lower quality videos on a mobile phone?
Yes,it uses more resources to play higher resolution content. But its not a waste because a majority of content is at that resolution

Well at the distance I use the phone 330ppi is optimal!
I think 330 is ok for phones. Look at the iPhones they've a good screen without having 400+ PPI.

I can see you're still a bit confused about your argument. PPI is not the unit of measure you should be using. It does nothing to tell us resolution OR screensize so as a number on it's own is entirely useless.
PPI is just a result of resolution and screen size
PPI = width squared + length squared, divided by the square root of screen size.
Optimal viewing distance is about resolution and screen size. The bigger a screen, the further away it needs to be for the resolution to be correct. You can't say "330ppi is optimal" because that's not how it works. You can have 2 completely different resolutions with the same PPI.
For example, on a 5" screen, 720x1500 would be 330 PPI.
Similarly, on a 10" screen, 1500x2950 would be 330 PPI.
The optimal viewing distance of both these example screens is completely different so to say that 330PPI is optimal for a distance is wholly wrong. You cannot use PPI as a valid unit of measure unless you first specify a screen size. There is no such thing as optimal viewing distance for a PPI.
Optimal viewing distance is about resolution and screen size. If you stick to 1 resolution (lets use 1080p as the obvious example), the optimal viewing distance of a 5" screen is less than the optimal viewing distance of a 10" screen. This is because the pixels are bigger on the 10" screen. if you compare an image on a 10" screen to an image of a 5" screen at the same resolution AND distance, and at the opwholeytimal viewing distance of the 5" screen, the 4" image will be crisp and share where as the 10" image will be blocky. You have to increase the viewing distance of the 10" screen to get the same crisp image.
wholey
You can practice this yourself. Put a 1080p movie on your Phone and TV. Watch the movie on your phone at 5" from your face. Watch teh movie on the TV at the same distance. Forget the fact you cannot see the entire screen. Focus on the centre of the screen. You will be able to pick out individual pixels and the section of the screen you are looking at will not appear as a single image. Just a series of blocks. The bigger your TV, the more noticeable this will be.
To get a 330 PPI value on a 4.95" screen like the nexus 5, and maintain 16:9 aspect ratio, you'd be looking at 1450x816 resolution. There are ways to work out optimal viewing distances, but it's quite complex. If you're interested, you can find that information here http://en.wikipedia.org/wiki/Optimum_HDTV_viewing_distance

CVR: Vertical resolution of the video being displayed (in pixels)
The optimal viewing distance for a screen the size of a nexus 5 is 7.2 inches (0.6 foot) - which is about what we hold it at.*
*based on:
http://www.calculatorpro.com/calculator/tv-screen-size-calculator/
http://myhometheater.homestead.com/viewingdistancecalculator.html
Now I suppose when we get up to 2k and 4k, there will be a problem. At that distance, the human eye may fail to recognise a difference between 1080p and higher resolutions. To get benefit, the screen would need to be bigger and further away...although some say for those holding the screen right up close to their face, characters will look better
All that said, I can recognise a difference between 720p and 1080p at that distance. So yeah, 1080p is about for a screen our size. Or also for a tablet, which typically would use ant a slightly further way distance than a phone.
So really, it all depends on your eyesight or how short your arms are. If you hold the phone too close to your face, 1080p is not optimal on a 5" screen. You would probably want a smaller screen or a higher resolution, otherwise it may appear blocky. At the appropriate distance for a mobile phone, anything over 1080p may be pointless but bringing it closer may prove beneficial, but that could cause eye strain as you're focusing too close.
There is a really useful chart here
In summary:
If you hold your phone further than the optimal distance, you may get away with losing some resolution as the further away it is, the less you'll notice. OR you need a bigger screen to make it the optimal viewing distance for that resolution
If you hold your phone closer than the optimal distance, you could need to get a higher resolution OR a smaller screen
Like TV's, you should buy the size or resolution based on your fixed viewing distance. For a TV, its the resolution standard of 1080p (because most of our content is that resolution) then you look at the distance your sofa is from the TV stand and buy the correct size. Assuming you need the same resolution for content on your phone, you look at the distance and buy the appropriate screen size. People who hold their phones closer will want a smaller screen for 1080. People who hold them further away will want a bigger screen at that resolution. This trend will continue as content resolution increases, but this cannot go on forever.
Yeah sorry, when i said "phone" i was meant aproximately 5"... Not 4" or 6" or much more.
I was trying to say that I prefer a 5" screen with 720p than a 5" screen with 1080p. Regardless of the lose of quality.

Ok no worries.
As I say, it depends on how good your eyes are and how far away you hold your phone. 1080 is about right for a 5" screen if you have 20/20 vision and hold your phone an average distance from your face, so the 1080p resolution is the average for our phone.

So then this probably means that you hold your phone a little further away than average... and if you do that's fine. It just means that you're outside the bounds of what a Nexus 5 is catered for, which is the masses (average)
EDIT > I'm like you though, but with 1080. 1080 is great for me with a 5" screen. A higher resolution at that size would be almost pointless for me as I would need to hold it closer, so to get a 2k phone, I would need a bigger screen size as holding it closer isn't really an option.

Just thought I'd say I agree with you lol 1080p is enough on a phone, for most. On a tablet however, higher than 1080p would be pretty nice if the specifications support it decently.

Yeah. I also forgot to say that bigger than a 5" screen is also not an option for me as I cant reach everywhere one handed. So I cannot increase screen size and I cannot ergonomically reduce viewing distance, so I am stuck at 1080. With a tablet, one-handed operation wouldn't be a restriction, so I could increase screen size. My viewing distance would be largely the same, so the 1080p resolution could get blocky with a bigger screen if I don't increase the resolution.
Not sure what the next gen of phones I buy will offer. I'm possibly willing to go up to 5.5". BUT I don't think that increase in size would warrant an increase in resolution for me. So if OEM's start to make 2k the standard, I'm going to have a problem.

The Nexus 5's 4.95" and 1080p already feels perfect.. I have a Note 3 and never use it since I hate the size (and not to mention being a Samsung product). I have a feeling that if newer devices are going to be larger, I'll be sticking with my Nexus 5 for a little longer.

Its a compromise. LCD is better colour reproduction but then Amoled have individual pixel lighting, meaning pure black saves energy and also can be used as a night clock without the entire backlight panel lighting up the room.
2 ways to address this.
1) Colour profiles for AMOLED.
2) LED backlighting like TV's for LCD
I love my lcd screen more than my friend's s4 amoled screen [emoji14].. Its colorful but not as sharp as that of nexus 5.. And whites are completely dead..

How will 1080p movies look on a 2K screen of the Note 4?

I am debating whether I should upgrade my Note 3 to the Note 4 in part from movie watching. I am afraid that 1080p movies would look blurry and less sharp due to the pixels being stretched out to fit the 2K resolution. I do not think that the note 4 has upconversion of 1080p to 2K. I do a lot of 1080p movie watching on my note 3 on the go.
If the 1080p movies look worse on the Note 4, I may just get the iphone 6 plus to try out the ios system since I have never own an iphone before. My previous phones were the HTC HD2, Note 1, Note 2 and I am currently using the Note 3.

do you have a phone with greater then 1080p?
I have a note 12.2 with 2560 x 1600 resolution and 1080p content looks like standard 480p maybe a little better.
I would find the best resolution as not to take it too big that it take up space on my device or rip too low that I see jagged edges. Definately not 640x480 rips.

No, I do not have a phone with resolution greater than 1080p but if you look at the post right after yours from a poster named Natienn then you can see that 1080p content would not look good in higher resolution screen. Maybe because the Note 4 is only 5.7" , the image quality may not be as bad as the bigger screen tablet with higher resolution.
Having a 2k display won't make a 1080p video looks worst, indeed it can look even better.
It will look like normal 1080p
720p movies look great on my 1080p nexus 7 2013, so I'd suspect 1080p movies would look great on a much faster device with a better display.
1080p videos look good on the G3

This.
After 3 pixels you get one more (1920 = 3*640 -> 2560 = 4*640). So regulary after 2 pixels, the 3rd one will be streched to match the next 2 pixels (3rd one and 4rd one). So every 3rd px is a double one.
But in reality, there is anti-aliazing and some others algorithm for upscaling, so videos will look even better. So I think, 1080p will look great on Note 4.
Now we are getting mathematical... That's just sad. The quality is dependent on the content. It will either look about the same or slightly better. No need to get all technical or defensive. It's the content that decides.

You are wrong. If you put a lower resolution source into a higher resolution screen the picture quality would look worse.

Hmm, I believe that in this case you're wrong buddy. Even the source being a lower resolution video than the display it will look better due the pixel density than it would on a Galaxy s4 (for instance) that have a 1080p display.
Obviously to take full advantage you should look for a 2k resolution video but the 1080p video will be better on n4 display (not because of the resolution alone) but because of the screen itself.
Both is same size 5.7" which means the video will look identical, plus side 2K display due to it higher density will make the 1080P movie look much better on Note 4.
my only theory is that if you take standard TV and put in on a HDTV it looks like crap, but if you put it back on a 4:3 old school tv then it actually looks good. But things have changed from back then so we wont really know until we receive the device and see how the hardware and software works with upscaling the video. That's what it all comes down to really.

The resolution of Oculus cinema for Gear VR illustrated

I bought Gear VR for Note 4 based on positive review, but after using it for two nights, I decide to send it back due to low resolution. Here's my illustration of how resolution is archived and my thought on it:
Movie watching experience: Low resolution ruins it. It's bad to watch anything on a 480p screen at a size of 200". Plus No DTS/AC3 support, no smb support in Oculus cinema.
Kodi supports DTS or AC3, but it also reveals that the field of view from Gear VR only covers part of Note 4's screen. See my illustration in attachment. The header, footer as well as 4 corners are not covered, which means that only central part of a movie is viewable.
Ideally, 720p (1280x720) resolution for each eye can be achieved from Note 4's 2560x1440 screen if the rectangle of half screen inscribed in the the field of view like some cardboard does. But the way Samsung's implementation of it's Gear VR makes it unable to fully take advantage of Note 4's screen. The best movie resolution that Gear VR can archive is 972x546. I understand that Samsung's take is good for VR for there is no unilluminated area within it's field of view.
I wish Samsung would come up with a new product that allow the rectangle of half screen inscribed in the field of view instead of the other way around. I think this can be archived by another set of lenes with less multiply factors than current ones. Even at 720p, the screen doesn't need to be 200". 150" would suits the pixel better.
When it comes to VR, Samsung Gear VR also suffers from low resolution. Plus 360 degree video makes me dizzy. I downloaded and watched almost all 360 degree video from youtube but I'm not impressed enough. The people figures are larger than real life. Everyone looks like giants in these videos. Among videos, I prefer those taken from a steady position. First person action view just makes me dizzy. I think it's due to my brain can't process it when the vr scene is moving around but my head is not.
360 degree picture is quite a pleasure to view though.
Sold mine to a colleague due to the exact same reasons

Not questioning the validity pic you put up, but can I ask how you came to the conclusion that it only uses 972x546 pixels of the screen? Is it official information, or did you measure it somehow?

That's based on my calculation given my understanding of how it works (as illustrated) is correct. Samsung claims the resolution for each eye is 1440x1280, which is misleading IMO. Same reason as explained in the illustration.

Just put my N4 in my Gear VR holding my thumb to the proximity sensor, so that I could see observe the screen when connected and they are not using a completely square image - it looks more like this (except there's a gap in the middle):
It also doesn't the entire width available, but it looks like it's using more than what you have in your picture. The gap between the images is about 4mm and the gap between the image and the sides is about half that (2mm). The top and bottom gaps are about 5mm. So it's definitely using more than 720 pixels for the height, but less than 1280 pixels for the width.
EDIT: I measured it using a tape measure (not any exact numbers, but more accurate than those I came up with).
So based on these measurements the screen would use about 1190 pixels at its widest point, and 1240 pixels at its highest.
The graph shows the best scenario, where movie screen fills your entire FOV. But this is not comfortable for most viewers, and you are likely to "sit back" a little. Since you're looking through the same matrix of pixels, you are then effectively losing screen resolution, going somewhere to 480p like OP mentioned.
What's also sad, when we reach the Holy Grail of 4K (with Note 5), the movie screen would still be only 1460x820.
If you want best experience with 2D HD content, you're better off moving your chair closer to a TV than strapping Gear onto your head.

Actually just tried to measure the screen in the cinema mode, and came up with ≈ 45mm. The screen width is 125mm, which means that half that would be 62,5mm, which would give us an approximate horizontal resolution of 45/62,5*1280 = 921pixels. Pretty much explains everything right there. Even with a 4k screen the horizontal resolution in a comfortable mode would only be 1382 px.
The screen height (screen is not a perfect rectangle) at its highest point is ≈25mm. So with a screen height of 70mm that gives us a vertical resolution of 25/70*1440≈514px.
So based on my measurements the resolution you get is pretty much 921x514 (screen is not a perfect rectangle) at the widest and highest parts.
When it comes to watching movies, the screen will be cropped to the aspect ratio of close to 1.78:1, that's how I estimated it at an effective resolution of 972x546 (the biggest 1.78:1 rectangle inscribed in the FOV circle).
You just showed that the actual FOV is not exactly a circle. Now the question is, is the actual FOV inscribed in the theoretical FOV, or the other way around. I guess a way to find out is to look through gear vr at a picture with measurement markers.
And again, in best scenario the effective movie-watching-resolution based on Note 4 screen is 720p (1280x720) considering the aspect ratio of 1.78:1. This best scenario is achieved when the rectangle of half screen (1440*1280) inscribed in the FOV. This is the case in my Chinese version of Google cardboard where the movie screen is smaller (equal to 150" from 10 feet away, more or less) and the pixel is less obvious. So the difference of this Chinese version of Google cardboard vs Samsung Gear VR is like 150" 720p screen vs 200" 5xxp screen.
Not sure about the original Google cardboard for I don't have one.

In theory (if my theory is not faulted), to be 1080p movie ready for each eye, the width of the half screen needs to be 1920, which equal to 3840 in whole screen. The height is already more than enough (1440 available, 1080 needed). So the resolution needed from the phone screen is 3840x(1080 to 2160, the former may make the phone too long, but who knows right? The latter will keep the same aspect ratio as Note 4).
Can the lenses on gear vr be replaced so that it will make the screen through it smaller, for watching movie's sake?
I love mine as a great start to mobile VR and i have watch lots of films via oculus cinema. Can't wait for note 5 and new gear vr but perfect start samsung

Here I'm mainly talking about movie-watching ecperience. The experience is ymmv. For a guy used to watch movie on a 120" projector screen, or a 60" 3D Samsung TV, gear vr experience is unbearable, while Chinese version Google cardboard is very impressive except for it's build is not goog enough.

I have a 120" movie screen (only 1080p though), and I personally don't find the experience "unbearable", just not as good. Still think it beats watching the movie on just your phone though or laptop.
Totally agree Toss3

Right, I realized that unbearable is too much of a word. I meant to say that I still prefer to watch movies on 120" projector screen or 60" LED TV over current gear vr. It's a pity because gear vr would have done better. I'm impressed with it's build and the quality of lens, but the lens is not of the correct multiply factor for watching movies.
The gearvr resolution actually gets better overtime as you start not noticing the screen door effect the more you use it. Sure it's not perfect but heaps better then the oculus rift dk2. I'm can't wait for note 5 version
Average viewable res is 540p. Void mode shows more content at about 640p since no VR graphics (depending on video format).
I prefer Void due to more of the video res shown, can view laying down and at least 30% more battery life.
