[Q] Screen Resolutions??? - General Questions and Answers

hi everyone
I need to ask something that i was unable to find answer on internet or Google searching. I come straight to the point. It's basically a general thing about devices that i found different in aspect of screen resolution and i couldn't find difference.
There is one Android device which gives resolution of 540*960 on a 5inch LCD and there is an Android phone which gives 1080*1920 resolution on 5.1 inch LCD like S5 AND 1440*2560 resolution on 5.1 inch LCD.
I want to ask what is the difference that these resolution gives, i am currently using 540*960 resolution phone and what difference i would note by using 1080*1920 resolution? will thing appear small on it?
For example on a home screen, i have a gadget of weather, will it appear more smaller? because i didn't get the difference of resolution and their result difference.

firstly i can guess by the post that you are a noob but would like to help you change to pro so here it goes
the difference are
420*320 and below ldpi-small- 2-3inches - packed with 100 to 150 ppi screen
470*320and below IS mdpi - normal- 3 to 4.2 inches - packed with upto 200ppi
640*480and up IS hdpi- large-4.2 to 7 inches - packed with 200 to 300ppi
920x720and up IS qhdpi- extra large- more than 7 inches - packed with >300ppi
if that's unclear to you
try searching up screen support on google or api guidelines

i am sorry if i sounded noob but i was unaware of these things. I was just wondering what's the difference of resolutions when the screen size is same.
From your post what i got was, that it is basically the PPI thing, which makes screen more bright and colorful etc. so more PPI is based on more resolution or pixels.
I am currently using Huawei G610s and it has 640*480 with 220ppi. I thought that resolution is same as in case of computers, the more resolution the more smaller the pixel and picture size and more desktop area. I am currently using 1680*1050. So i thought in same context and was wondering and thought to ask.

firstly ppi refers to the pixels per inch
it in simple words is how tightly pixels are packed in a sq inch of area on the screen . the more the ppi count the smaller each pixel gets providing you with sharper and intense quality display
also if you did not search api guidelines on google
i am here to help you
here go ahead and just go through the detailed version and i think it will solve almost all of your query

don't forget to hit thanks :good:

Now. Don't get concerned on how you sound. We were all like that at some point. The resolution that you have probably is around 200 DPI (depending on screen size) My phone (Xperia SP) has a 4.6 inch 1024 x 720 display AKA 720p display. In person, how they look actually matters. Anything above 300ppi is crisp and extremely sharp. A Samsung galaxy s5 has a PPI of around 400. These numbers don't really matter but if you see them in person, they really look nice. Hope I helped you.

[Q] Higher Resolution Android Phones

I'm very surprised the Nexus S didn't come out with a higher resolution Super Amoled screen. Apparently, 2.3 supports higher resolution according to wikipedia. I'm just waiting for a new android phone with a higher resolution/pixel density to put the iphone 4 to shame.
Imagine, a Super Amoled screen with a 1024x768 or 1280x720 resolution would be the best mobile phone screen in the world.
When do you think we will realistically see android phones with higher resolution displays?
The current Super AMOLED screen already trades blows with the Retina Display. I'm sure there will be higher res screens at some point but whats the rush? Wouldnt a higher resolution screen be more of a burden on battery than the current screens already are anyway? I'd see resolutions that high being more relevant for tablets and PMP than phones.
Why? It will drain battery more and more, and higher resolution don't need for still small display. Just imagine, MP3 player with Desktop resolution.
Haha? Try push sensor button, wtf it's so small...
U wanna get more ability to use sensor keyboard? (sarcastic)
Well, android definitely needs to match or better the 640x960 resolution of the iPhone 4 to maintain feature parity.
The current SuperAMOLED screens are less battery consuming than old LCD and Retina, so bigger resolutions shouldn't be a battery problem.
But what's the point of having 1280x768 on a 4" screen?
I'm pretty satisfied with 480x320 on 3.2" and 800x480 on 4" looks also awesome.
The Meizu M9 have a 960x640 display, but (even if you are in china) this little boy is still difficult to find.
The next Meizu (M9ii) will have a 1280×854 or 1280×800 4" screen, and should be animated by a Tegra2 with 1Gb of RAM. They said that the release date will be on middle 2011, so maybe we will be able to grap it in the late 2011.
The two phones are running on a custom android 2.2 (the UI is very different from the classical Android).
For the battery, it's more backlight that drains power.
A higher resolution will only put a little more stress on the GPU, but if the OS is well coded, it should not consume a lot more.
DPI, its all about DPI
You can have all the DPI in the world, but all its gonna mean is LAG and Battery if we're still relying on the CPU to push pixels.

You have absolutely no comprehension of what resolution is. Look at the iphone going from 480x320 to 960x640. Did the icons get smaller? No I didn't think so. You simply put more pixels into an icon the same size. Because it seems you're under the impression that pixel count determines image size.
however, there is no need for a higher resolution because the display is that too small. better resolution would look like the same as the resolution looks on current phones.
I can see several reasons to be interested in higher screen resolution (but IMHO you will need at least a 3.5" display):
Games
ok, that's not for today, but with ports like the unreal engine on android, phones will become more like a mobile console (PSP phone, for example). A better resolution sounds like a better playing experience, but will still need more powerful hardware (and that's on the way with multi core SOC)
Video
isn't that obvious? and it's essential if you're watching videos with subtitles
Internet
I don't know for you, but on my 800x480 handset, i have to zoom out to have the full page, and zoom in, etc...
With a better screen resolution, the navigation will be easier
It's not interesting for everybody, but I think clivo360 and I are not the only guys looking for a higher resolution screen
Although 4.3" is probably the upper limit for what you'd consider "pocketable", I'd still be attracted to bigger screens and more powerful phones because there are things that can take advantage of them, such as video. Imagine 1080p screens on a phone!
At some point though, phones are probably going to suffer the same problem that PCs did - that hardware outdoes all user needs. Imagine a point where the hardware has reached such a point where for the average user, they don't need the most potent phone anymore. We're already well on the way there. It happened with PCs, where the average user needs office software such as word processing, a spreadsheet, and the Internet, but nothing that demands crazy hardware (the average user is not a high end gamer we're talking here).
A better resolution makes even more difference on an SAMOLED screen compared to an LCD/SLCD - due to the PenTile matrix configuration of pixels a 800x480 SAMOLED screen doesn't really have as many pixels as an 800x480 standard LCD.
Just take a close look at the screen of a Nexus One or Nexus S at some text and you'll see it's slightly fuzzy. See here for more info
Better resolutions aren't available yet because a) it's a relatively new technology and b) manufacturers are having a hard enough time making enough just to cover the existing devices that use them.
AFAIK, there is only one Android device with a larger screen resolution that, as long as you don't live in the good old US of A (and even there it can be done), can make calls: the Samsung Galaxy Tab. But not exactly small enough to fit in your trouser pocket (although it does slip easily into a jacket pocket).
PS: The Tab is fantastic for video (1080p MKV supported), games and general browsing (with plugins set to on-demand) plus the odd short book, although you do look very strange if you answer calls on it without a BT headset (very Trigger Happy).
Ugh, I won't flame people saying we don't need higher resolution, though I wanted to...
Here is one basic application where the higher resolution really does make a difference: Reading text .PDFs.
I tried reading PDFs on my 800 x 480 Samsung Fascinate (Galaxy S) and I wish the text was a little smoother. Sure, I'd like a slightly larger screen (no more than 4.3") but if the screen was larger I'd be even more desperate for higher resolution. I'd like to see 1024 * 640 on a 4" Android.
Higher resolution does not nesc. need more battery/CPU power: it's the brightness that uses the battery most.

Doesn't your phone's AMOLED screen use the PenTile matrix? If so, that's a huge factor. I have 2 Droid Incredibles, one AMOLED w/PenTile matrix, the other SLCD. The SLCD has MUCH smoother text despite both being the same 480x800 resolution. AMOLED w/PenTile matrix has a "screen door effect".
Anyway, Toshiba might make your dream come true, and even exceed what you'd like to see.
http://www.engadget.com/2011/05/16/toshiba-enters-pixel-density-fray-with-367ppi-lcds-for-cellphone/
its true about the screen door effect. texting the g2x is very smooth dispite the resolution being the same as the vibrant.
Not sure I could put larger than 4.3" in my pocket

5.3" device: question about cpu

Does a larger touch screen With same resolution need a faster cpu?
My doubt is about larger touch screen, not actual screen size. Would touch-scrolling run smooth With 800x480 resolution and 5.3" size?
This could be The case: use blu studio 5.3" screen With ZTE tania hw.
If the screen is of same resolution, the load on the SOC is the same.

Thanks. I hope bluproducts (and other minor manufacturers) will offer WP devices soon.
MS should give WP to manufacturers for free and ask a fee for xbox live/bing maps only (the way nokia is doing With its maps)
Displaying the same resolution uses the same CPU cycles regardless of physical screen size. However, a larger screen size might require a more detailed touch-sensor grid and I'm not sure if that would result in more CPU cycles or just greater battery drain (relatively speaking).
but on big screen lags are more visible!
so from user experience point, large screen devices need better CPU

that's exactly what I was asking.
I'd try produce a 5" WP with 1Ghz for 199 similar to the blue studio offer

That's right. Unfortunately ZTE didn't release a 5" WP but just another 4.3"
A 199 5" WP would sell very very well.
Unless they tweak the god damn OS to a new level with higher resolution... i don't want any kind of devices that i have to see my pictures as numerous of square pixels (visibly)
And i don't think that you would ever have WP on a tablet and 5.inch is something related to a tablet, not a phone anymore. my Titan is 4.7 inch and it has touch the lowest PPI and the size of my pocket.

resolution is fine imo. 10" netbooks are usually 1366x768 therefore 5" @ 800x480 are more than accettable.
regarding WP on a 5.3" tablet, why not ? you know women's purses sometimes are so small that no tablet could fit into them...

[Q] 1280x800 vs 1024x600 tablet

Can someone clarify this for me?
The biggest difference between 1280x800 vs 1024x600 tablets are more dots per inch for the 1280x800. So more detailed pixels for same area, so perhaps better picture.
Now I am not sure completely sure if 1280x800 allows more widgets. One of the limitation with 7 inch Galaxy Tab 2 is that screen area does not allow to put more than one 5x4 widgets in the same screen due to screen being 7 inches rather than 10 inches. Now if I get 1280x800 7 inch tablet, such as Nexus Tablet, would it allow me to put more widgets in the same screen? I would greatly appreciate if someone can answer this.
Is there other advantages for having larger 1280x800 resolution than what I have already mentioned?

If you are typing this on a computer, change your resolution and see what happens. That is what the change will look like between two tablets.
Technically the greater resolution doesn't allow more widgets, it's however many spaces your launcher supports. Download Apex and change your homescreen size to something like 8x8 which will allow much more than the default.

Not true at all. Changing the resolution on your computer is completely different due to dpi settings in android. DPI settings in android mean that only the physical size of the device determines the amount of icons. The size of items stay the same regardless of resolution UNLIKE desktop operating systems. A 4 inch phone will have a 4 columns whether its 720p or 320p.

Utilizing Space
With Galaxy Tab 2, I notice that a lot of the space in the screen is not being used. When I try to put widget in that space, it is not allowed. Is this due to the fact that our resolution is not 1280x800?
If that is true, is there any way to use the full space for widgets without buying Nexus 7 tablet or other devices with higher resolution?

wallapapers!?!

Hi all!
I've had many android phones but this is my first tablet. I'm trying to find a good background using the standard wallpaper apps on play store but they all look like crap on this giant screen! Any advice? Do I need to use an app specifically for tablets or do I need to somehow modify the wallapaper?
Also just out of curiosity can someone please explain to me why this is? If my tablet as similar ppi why does a wallapaper made for a phone look so bad on a larger screen? I'm know there's an obvious answer but I'm not that savey with hardware and am trying to wrap my head around it
Thanks!

Main reason is resolution only thing close to this resolution wise is the LG g3 at 2560x1440.
Some nice wallpapers here. 2560 x 1600, 2880 X 1800 and UHD 4K at a crisp 3840 X 2160 resolution.
http://www.hdwallpapers.in/
Here are some wallpapers at an amazing UHD 8K of 7680 X 4320. Hope you can find a suitable image.
http://www.wallpapersultrahd.com/
ppi density (pixels per inch) is not the same as the actual image dimensions. You need at least 2560x1600. Higher is better.
As for good wallpapers, moving ones are much more fun. Personally I'm using this one: https://play.google.com/store/apps/details?id=com.dualboot.apps.forest

367 ppi enough ??

Hi all, i want to buy this phone but i have one question. Is 367 ppi enough ? Is display sharp enough ? I have read many reviews and test...., in some reviews testers say that the resolution is absolute ok....., in another that is visible difference in sharpness when they compare the screen with higher ppi. What is your opinion ?? I have no chance to see the screen in shop. I want to buy this fone, but i´m worried about this thing. Thanx for answers
The screen is very good, excellent contrast and beatiful colors, for me is ok 367 ppi

DPI <> PPI. PPI is the physical amount of pixels per inch, DPI is the amount of Dots per inch displayed by the OS.
This phone has a great display. I wouldn't worry about the relatively low PPI compared to newer phones.
I switched from a Samsung with over 440ppi and could barely notice any difference.
Sent from my HUAWEI MT7-L09 using Tapatalk
I have the Ascend Mate 7 from May and after seven months I am not satisfied.
However, regarding the display I must admit that the difference is unnoticeable with 400ppi or more but the problem is not the dpi. Let's view:
- The screen manufacture
I have a big halo in the center of the screen on white colors (It is getting more annoying).
I have a "light" lightbleed on blacks
I don't think that it's a true IPS because if I look it from different angles the screen colors change, especially the black colors
- The Android UI
We have 367ppi on 6" screen and the huawei stock rom is set to 480ppi, so Android will render the screen as it is a 480ppi display. Big status bar, big everything (but this is up to you, I prefer a small UI). To make matters worse for now is impossible to build a custom ROM that it is not stock-derivative (See my post here).
