Hi guys,
I currently have a 9.7 inch ICS tablet which has a pixel density of 132, just like ipad 1 & 2. I thought it was not that bad until I got a phone with pretty high ppi (HTC One V), and now it suddenly makes my tablet look so cheap when I look at it. So I would like a tablet with higher ppi, and I thought how about an 8 inch tablet with 1024 x 768 resolution? So I tried the ppi calculation online, and it gave me 160. are 160ppi and 132 ppi a big difference in text sharpness? Currently, on my 9.7 tablet, even the blue digital clock in the status bar is somewhat pixelated.
Also I like to use 4:3 tablet in a portrait mode only, so when I'm web browsing with my 9.7 inch tablet in portrait mode, some small texts are kind of readable, BUT uncomfortably... like you can go on Yahoo desktop website in portrait mode, and try to make out the smallest text in that website, and it's kind of garbled looking. So I was wondering, IF PPI is higher, EVEN THOUGH the screen is smaller, will that make the texts sharper for the same webpages? If I had both 8 inch and 9.7 tablets, I could test it out, but I don't, so I need expert's knowledge..
Also, 8 inch tablet is cheaper and lighter than 9.7 or 10.1 tablets so I am considering this option more now.
Please answer my questions above!
Thank you.
Don't get too star struck, htc devices are meant to beautiful and only other htc devices can give you that premium look and feel, ( no company tops htc in the beauty department). My htc sensation resolution is 540×960 and has a 256 pixel density and 240 dpi. It come down to the quality of your tablet, by increasing your dpi (almost like zooming in) you will see more pixels (BAD!), but you will see the difference is you increase the ppi, however it depends on your display. Right now the top android phones (htc one s/v and sgs2 & 3 and etc) have better displays than tablets and those 7 to 8 inch tablets aren't recommended also. They are build to be budget friendly and the display quality won't be too good either. Maybe you should get a better android tablet (asus transformer prime the BEST) or iPad+Retina Display= Big Smile
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.

Did you have a prime to compare it to? Sorry, but text IS crisper on the prime. I see it with my 20/20 eyes.

Lol as a former owner of both (returned Prime C1 for 700 a C6 then returned that, and I started the thread in Prime forums for users who Asus lost our first mailed GPS dongles)- your fooling yourself or you got a N10 with a bad screen

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.

Mine has this problem and so do at least a few others. See http://forum.xda-developers.com/showthread.php?t=2007676
I'm still debating if it annoys me enough to justify an exchange.
Hi,
1st off I love this phone. I am extremely pleased and have zero complaints so far. Buttery smooth too....
My Question is how is it possible that the screen resolution is adjustable? Does the display turn off pixels? Does it merge pixels? Please enlighten me..
Thanks,
Joel
I'm pretty sure it must be 'rooted' first to allow those changes.

Sorry even though u r pretty sure. This info is wrong. U DON'T need root. Just like samsung graxe ui. On LG V30 u go to display - screen resolution and switch between 720,1080 or qhd+.
But the OP never asked if changing resolution was possible. He most know that we can already change res in the setting. What he is asking is HOW does lowering resolution works.
Im not sure about this but from tv or any pc monitor u can upscale to max reolution of the monitor or downscale to a lower resolution. The pixel are still on but the screen is not push very hard.
Amoled are very power effecient and this has been discuss in the S8 forum for quite sometimes. After all the testing the xda members have been doing it seems that going from QHD down to 1080(full hd +). Doesnt save that much battery (around 5% better battery)
Actually I'm wondering because on a 1080p TV, when you feed it a 720p video, the TV stays 1080p. The video is just enlarged to fit the 1080p display. On the V30 I'm under the impression that the display will actually change. Kinda like having a 3 displays in 1...

U wont see a smaller screen. The screen will stretch out edge to edge but it will look very blurry if u do 720p. Not so much in 1080p mode. So u can say that the software upcales lower resolution. Just like riptide 2 which u can lower or max res in the setting of the game.
Wait, so the software downscales? You sure? Just Android or all apps too? I don't think so. How could software down scaling effect battery life?

The screen is cap at 60 hz. Let say u are playing a game ( this goes with the ui smoothness aswell). Since the screen is cap at 60hz means that the fps is up to 60fps max/cap At 1080p is you play a game that can reach 80fps(cause is not pushing QHD pixel) the cpu/gpu doesnt have to work has hard. So instead of doing 80fps it only have to do 60fps meaning that cpu/gpu doesnt have to work 100% since is able to maintain easily the frame per second require from the 60hz screen.
This is why the new RAZER phone with 120hz screen can do 120fps.
Now if u increase the screen to qhd (1440p+). The same game with higher resolution the frame rate will be much lower. Now. The game probably is reaching 55fps instead of 80fps max (is an example). The screen is 60hz (60fps). So the cpu/gpu is gonna be working 100%. Much harder cause is trying to reach 60fps but it cant. Which equals more power comsuption, hotter device and also cpu/gpu throlling cause of the heat.
I was just wondering what display settings does everyone use and how to get the best performance out of the display. If anyone can tell me all the things to turn on and off for getting there, it would be great.
Thanks

I use the best settings possible, what's the point In having a good phone with the best display if you ain't gonna use it
Exactly. When you say best performance, what are you looking for? Higher synthetic benchmark scores to brag to your friends who also don't understand benchmarks, or the best looking display to actually USE the phone?
Do what makes sense for you. I keep mine on HD+ (720 pixels in the short direction) because my eyesight isn't great and I can't tell the difference. Samsung pushes the higher resolution because it looks good on paper (specsmanship), however I am doubtful that most people (even with good eyesight) can tell the difference between FHD (1080) and WQHD (1440) pm this size phone.
Other people don't matter, check for yourself. I would look at straight diagonal lines and text. If it looks jagged, then go to higher resolution. If not then try lower resolution.
There is a small battery gain from using lower resolution. You can see what Samsung thinks the battery gain is by going to the battery power saving screen and note the savings projected in the "apply" button at the bottom. Change the screen resolution and the projected savings in the apply button will change immediately. The change in projected savings between two modes presumably represents the difference in power consumption that Samsung estimates. For me it is rough ballpark 10 minute life saving from 1440 to 1080 and another 10 minute saving from 1080 to 720 (when checked with battery near full)

I was referring to display performance, which includes having the best visually appealing display settings. I do not care about any benchmark scores. I believe most people have stopped caring about that a while back.

Thanks. I do keep my resolution at WQHD at all times. I was wondering about all the other settings such as Settings -> Device Maintenance -> Performance Mode -> High Performance (I've heard this is needed to get the best display) and other things such as what screen mode looks the best and most saturated (Adaptive, AMOLED cinema, AMOLED photo, etc.) or if there are any other settings.
Guys what settings you keep in adaptive display?
The difference between HD and wqhd is easily noticeable, I have mine on mac settings and the screen is stunning

I want to buy S21 Plus but I know that Ultra has a higher screen resolution. Has anyone been able to put the two side by side and examine them? Is the difference in resolution visible to the naked eye?
I am currently using S8 Plus in FHD mode. In theory ,S21 Plus has lower PPI than S8 Plus when use it FHD mode bcz of bigger screen.
It depends on your visual acuity and what you're viewing. You can try for yourself by comparing an image at two different resolutions (of the correct ratio) side-by-side on your monitor, viewed from a distance that creates the same pixel density in your visual field as your phone has.
I've got 20/15 vision, I can't tell any difference. Even holding the s21 ultra an inch from your face and changing resolution, you can't tell a difference. The benefit of the ultra is better zoom camera and battery life (mostly from the lower power display).

Some can't, some can. It depends in part at what you're looking at. If there's text or other visual detail that's just at the border of what can be resolved at the higher resolution, then it's illegible at the lower resolution.
I can tweak the resolution back and forth on my Ultra and there is a difference, it's very subtle but it's there, to be fair FHD+ is more than good enough for everything though.
