[Q] Screen Resolution !! - Android Q&A, Help & Troubleshooting

I am new to samsung, i want to buy samsung galaxy 3 but when i check the specification, i saw that it has 720 x 1280 pixels,
how can i play videos thats 320*240 pixels, or 640*360 pixels, it seems loosy!!!
how can i play videos without loosing the pixels???, give me solution?
and why samsung creates high resolution mobiles like that!!!

Videos of lower resolutions will be scaled to fit the display in most android video players.

Any difference b/w 1920x 1080 and 800x 480

Hello guys I've been converting my videos to 800x480 for awhile and their all fine. I was wondering if I convert them to 1920x1080 would there be a significant difference since the SGSII's native resolution is 800x480. Thanks for answering my question. Oh yeah the resolution the videos come in are usually low quality like 704x400 usually in .rmvb format. Sometimes I do download 720p videos and convert them to 800x480.

I've been converting mine as well, no difference at all. I just maintain the bitrate and it also reduces the file size.
GS II's screen resolution is 480x800. So anything above that resolution is practically meaningless, let alone 720P or 1080P.
Regards.
I can argue about that.

max HDMI output resolution?

what is maximum output resolution over HDMI out? it is the same like screen resolution 720 x 1280 with optional upscale to 1080p?
i will connect it to 1080p PC monitor, so i'm wondering about resolution, and picture sharpness
I can't find anything that says exactly what it is, but I'm pretty sure it's whatever resolution the phone is (for the Samsung Galaxy S3 that would be 1280x720). Hope that helps.
P.S. This should be in the Q&A section, not the General section.
If the video you are playing on the S3 is a 1080p video, even though on phone it will be rendered at 720p it will display on the external display at Full HD (1080p).
Same with the videos recorded on the phone. They render on screen at 720p but on external display via the cable will be at 1080p
1080p
Over 9000.

disappointed with screen

I just sold my transformer prime infinity...and coming from that, im disappointed with the screen. How could a lower resolution screen on the prime look sharper than the one on the nexus?
Well I was just looking around here and I don't have a Nexus 10. I got a Galaxy Note 10.1 and from my experience the picture matters a lot.
I mean there are a lot of wallpaper sites with ultra HD and optimized wallpapers for retina display, but the same resolution is not always the same sharpness. some are crappy cropped or zoomed.
Use quickpic to set your background picture. The stock gallery app sometimes crops the pictures false.
And pictures with a resolution below the maximum resolution will always look a bit crappy. that means that when you are using a fullHD picture, which was nice for transformer prime, it can look less sharp on a display with higher resolution like nexus 10
I too come from Prime and there is no contest, this screen is sharper than Prime by miles.
How stuff looks will depend on what you are seeing.
If you have set regular wallpaper, it will look all blurry thanks to resolution. Even so called HD wallpapers will look blurry on this. You need to go search for wallpapers for MacBook Pro retina and use those on this tablet using quickpic. None of the apps from Android market have good wallpapers that are having native resolution of this tablet.
Text is sharp and crisp on this.
Most arcade games are not optimised for this screen and look terrible or blurry. That is not screen's fault.
Desktop web pages look nice full and crisp. So only real issue of lack of sharpness comes into picture when the content is not ready for screen. That includes apps, images and games.
I also come from Prime.
I wouldn't say the Prime screen looks sharper than the Nexus 10. Reading text on the N10, for example, the resolution is really amazing, very nice on the Nexus 10.
The colors and brightness and blacks is a different story. The Prime had those 3 much nicer than the Nexus 10. I loved playing Marble Blast on the Prime, the graphics looked amazingly vivid. On the Nexus 10 they appear as meh.
Its the prime infinity. Drastic difference. What a shame. Gonna put the nex up 4sale.

It's mainly because a lot of apps and mobile sites and such aren't made for the resolution. It's made for a smaller resolution, so to make up for that, the apps, mobile sites, and whatever else are all upscaled to fit the 2560x1600 resolution. While upscaling allows you to view things bigger, it will also make everything else a slightly blurry. There are upscaling algorithms to make it look better, but basically it's impossible to make upscaled images look as good as a native 2560x1600 image.
A 720p 10" screen (Note 10.1) will show a 720p video the cleanest because the video outputs a ratio of exactly 1:1 pixels.
A 1080p 10" screen (TF prime) will show a 720p video a bit blurrier because the video outputs a ratio of 2.25:1 pixels.
A 1440p 10" screen (N10) will show a 720p video the blurriest because the video outputs a ratio of 4:1 pixels. (I know the N10 has a 1600p screen, it's just to make calculations slightly easier)
Now when using a 1080p video, a 720p screen will show no improvement because the screen can't output those extra pixels.
When using a 1080p screen, the screen will look sharper than that 720p screen because you have more information. Consider watching TV of a 10x10 resolution vs 1920x1080 resolution. The 1920x1080p resolution will look far better
Once again, the 1440p will look slightly blurry.
Now when you use a 1440p video, you can probably guess which screen will output that video the cleanest.
So basically, this high resolution thing is good mainly for texts as of right now since nothing is really optimized for a screen beyond 1080p.
Anyone who thinks its possible for a much lower resolution screen to be sharper is a fool. This screen is absolutely dazzling. Though content displayed is obviously going to have an affect.
And just to shove some numbers in your face:
N10 - 300.24 PPI (2560x1600 @ 10.055") 4,096,000 pixels (78% MORE)
Prime Infinity - 226.42 PPI (1920x1200 @ 10") 2,304,000 pixels
That's a huge difference.

I actually have to disagree with you a little bit here. 720p video should look just as good on the Nexus 10 as it does on the Note 10.1. 1280x800 times 2 is 2560x1600. Because of that each pixel of a 720p video will take up exactly 4 pixels on the Nexus 10; however those 4 pixels on the N10 are the same area that would be a single pixel on the Note 10.1. This is a clean ratio. On the TF700 you got to 1920x1200 which is 1.5 times 1280x800. This is not a whole ratio and means that pixels of a 720p video will take up between 1 and 4 pixels on the TF700 display (determined by a fancy algorithm for scaling images).
The Nexus 10 playing 1080p video should have about the same blurriness as the TF700 playing 720p video.

You can most likely blame that on googles new font rendering in 4.2. They turned down the font hinting a lot. It would be nice if it was configureable like in Linux. It the same way on the galaxy nexus and nexus 7 in 4.2.

The problem with this screen is calibration and black levels.
Colors are extremely washed, red is a poor red, same with blue. This totally kills the screen. If you compare this with ipad screen, you will cry. Not because of viewing angles, not because of brightness, because of colours. Google was really smart when they decided not to calibrate their screens, same with nexus 4, while other OEMs take care of this thing deeply.
And black, despite numbers of the reviews, its quite poor, mostly because every single unit has light bleed (some with a hard mess, others this problem is smaller)
As a result, a top screen with such a poor implementation. This could be best screen in an tablet ever, and now it is a mediocre one, with many pixels, but nothing else. And it's a ****ing software issue, thats so sad.

Yep, meant the calibration thing, it's about software. Black thing is because a bad manufacturing process, probably because of low price tag., or crappy manufacturers.

Wow...that blows. Maybe we need a 4.1 ROM??
I saw light bleed as soon as I turned my N10, but that's not the reason I just called to return it -- it was the uneven brightness. The top 1/2 inch of the screen is noticeably darker than the rest of it -- not visible when watching a movie or playing games, but very distracting when surfing and reading books, especially in portrait mode.
Since I haven't seen anyone else complain about this issue, I'm hopeful the replacement will be better.
Yep, I completely agree with one of the previous posters, this is definetly a black level issue. I put the iPad with a Retina Display right against a Nexus 10 both playing the same 1080i MKV. The iPad clearly won.
I still like the Nexus 10 a lot and I find it very comfortable to use because of how thin it is and how light it is, but to improve the product I think Google missed it some here. They could lowered the resolution considerably (1920 x 1080 is more than fine), improved on black level, and used the same processor. The lower resolution would have allowed that processor to scream since it wouldn't have been as taxed to interpolate so many pixels.
I don't know if it is a software issue or not, but if it is I really hope Google releases a fix. If there was a way to adjust Gamma or Contrast it might help considerably.

There's no way on earth text (or other computer generated content like the UI and icons) will look better on a 147PPI display (Prime) vs. 224PPI (TF700) or 300PPI (N10). The reason is as 404 Error did a great job of explaining is that text is a 1:1 match pixel wise; the more pixels the sharper the image. Photos and videos display even the clearest content over multiple pixels so the advantage of a higher PPI becomes less pronounced. And the human eye (even yours) can't resolve sharpness over 229PPI beyond 15". So, your 20/20 eyes are decieving you. The N10 has less contrast and isn't as bright as older displays so that might be what you're reacting to.

Video playback and black bars

Hey,
I got my Galaxy Tab S3 today and to my surprise, Youtube videos and Twitch streams have black bars on top and bottom of the video. I knew the S3 had a 4:3 ratio before I purchased it, but I didn't think that it would affect video playback.
My question is if there is a way to make it show 16:9 videos without black bars at top and bottom?
You could chop off some of the stuff on the sides and convertting the video to a 4:3 format. Shouldn't have any bars that way...
I guess I just bought the wrong tab for viewing videos. The black bars is annoying as hell for me.

Surely you realise it's impossible to fit a 16:9 image within a 4:3 screen without either compressing the image vertically or chopping the sides off?
Mxplayer will let you adjust the ratio to whatever you want if you wish to fill the screen.
If you want true 16:10 then the Tab S is still the best option.

Try this:
* Jedi hand-wave* These are not the black bars you are looking for.
In the event of a sub-par connection to The Force, you could try watching in a sufficiently dark room to trick your mind into not seeing the black bars.

That didn't work.
I went with Ashyx's suggestion and found a cheap used Tab S. The screen is about the same just with 16:9 aspect ratio.
I'm only going to use it for movies/series, watching streams and Youtube. Don't need all the other fancy specs the S3 has for that.

I honestly didn't think it would matter. I thought it was just a matter of using a program to change the aspect ratio and resolution to go with it and it would work. Like on a PC monitor or TV. Tried that and didn't work like I thought it would.
I went with your suggestion and found myself a Tab S 10.5 for cheap. I only care about the screen and not the other specs. Only difference between the S3 and S is the aspect ratio and HDR capable. I get my HDR fix on my TV.
Thanks for the suggestion.

The Tab S is still a great tablet, with a plethora of custom ROMs. If the battery in mine could hold a charge for more than 30min of light usage I wouldn't have upgraded to the S3

This is exactly the reason I decided on the tab s3. My tab s 8.4 is a great unit plugged in, but dead within an hour or so doing anything other than playing poweramp with the screen/wifi off. It does amuse me that 16:9 content on the S3 is only a little bigger than on my 8.4, but the faster specs are nice for casting Kodi or Amazon Video content to the tele.

I prefer the screen on my old Tab S 10.5 to the one on my Tab S3. It has a higher resolution (2560x1600 vs 2048x1536) and pixel density (288ppi vs 264ppi).

I think they both look good. I can't say I notice the ppi difference, but I don't exactly bury my face into the screen. I prefer the 16:10 ratio and the tab s 8.4 size, but unfortunately there doesn't seem to be any decent spec'd tablets currently available.
I have both now.
Side by side when playing a 60fps youtube video, the image movement is smoother on the S3 compared to the Tab S, but the black bars is gone.

I'm not convinced, if this would be visible. Probably depends on your visual acuity.
Mine is not the best, and for the life of me I can't see the difference between 1440p and 1080p on such a small screen.

There IS it, I ve paid for it, and I WANT it.
And experience will be different for me when viewing large size image in 1:1 scale.
It is just like refresh rate, since there r people cannot get the difference between 120hz and 60hz(or lower). But you cannot just disable higher refresh rate FOREVER just because there r some people cannot distingurish.

It's also to remove unnecessary downscale/upscale when watching a 4k movie. Since most app view the screen as a QHD one, VLC for example, will render a 4k video as a QHD one by downscaling it, then the phone will upscale it back to 4K.
Sure you will probably not see a lot of difference with native 4k as the upscaling technology from Sony is pretty good and you still have the 4K screen resolution giving extra sharpness.
Also, what some people seems to forget, is that the image displayed will always be 4K on this screen, a FHD image will be upscaled to 4K by the phone, and the higher pixel density make it far better than the same FHD content on a QHD screen especially for AMOLED screen that are somewhat blurry on the edge due to the subpixels arrangement.
This being said, you can put the screen in native resolution all the time, just going in the developper option and setting the screen minimal width to 1644pixels to match the 1644*3840 pixel resolution. Doing this, VLC that I tried perfectly render a movie in 4K, but your overall UI is ****ed up and you can barely use the phone. That's not what is wanted. Sony is just boring us for 4 generation with its 4k white list apps. I don't even know what is the recommanded app to watch their 4k HDR spiderman extract.
It's stated that the screen only runs at 4k in certain apps and scenarios, Theres no option to change that.
More accurately: The phone only render graphic at 4k in certain apps and scenarios*
The screen always runs at 4K since it's hardware and number of pixels can't physically be changed. The phone upscale every content to 4K all the time but render some whitelisted app directely in 4K. Still better than proper 2K as the pixels are smaller, but also mean your 4K videos on VLC will be downscaled to 2K by VLC then upscaled back to 4K by the phone, only because Sony didn't whitelist VLC that is perfectly able to run native 4K.
I almost have the same question, but instead of 4K I want to set a global 2K resolution.
4K is way too overkill, but 2K is the best middle ground between display clarity and battery life.
that is what you basically have, 99% of the time your phone won't render 4k. Doing that for all scenarios in which things are rendered in 4k would make absolutely zero sense because then they would need to be upscaled again to fit the 4k reselution
