Alright so the screen resolution for this device is 320x480, and the default android home features 3 screens. Wallpapers are stretched across all 3 screens..so you would think 3x the width with the same height. However, most information I find says that the correct wallpaper size would be 640x480.. which would only be 2x the size.
It's easy enough to just say double the width, but that only works for 3 screens(?). I'm interested in the formula here so I can determine the correct wallpaper size for 5 or 7 screens.
Is it the obvious +1/2 width for each additional screen? For instance:
320x480 resolution, 3 screens. 320+(320/2)+(320/2)= 640, 640x480
320x480 resolution, 5 screens. 320+(320/2)+(320/2)+(320/2)+(320/2)= 960, 960x480
400x854 resolution, 3 screens. 400+(400/2)+(400/2) = 800, 800x854
Am I on the money with this?
I dont think it actually adds anything to the size with more screens. I think it just divides it differently. I have used the same wallpaper with 3/4/5 screens and the pic is always the same.
You have to remember the wallpaper doesn't get stretch rather the space on top of the displayed area gets divided depending on how many home screens you have. In all the final wallpaper is still 640x480 but it overlaps in 3, 5, 7 etc places.
Just think of each of the 'screens' overlapping to understand how the homescreen works.
So then the proper wallpaper size for any Android device is 2x width x height? Or is it device specific.

i think now with the Tattoo being available it depends on the device.
i think i would go with 'device-specific'. i'm curious what resolution builds like the pulse version uses.
it's rather apparent that the current 320x480 devices just use a shorter pan across a 640x480 image when the number of homescreens goes up. i suppose we could all just use larger wallpaper images, since android will crop oversized images to the appropriate resolution depending on what device it's on.

I read the Pulse uses a 2:3 ratio, it uses two rows of three screens after all. I read something like 512x768 works well.
As Prash said.
For the G1, wallpaper is 640x480. If you had 50 screens, it'd still be 640x480.
However, different devices have different screen resolutions.
Not even worth reading

Just take the original width and multiply it by the number of screens you have. No need to do this /2 crap. Makes no sense....regardless of what you read. Now...if you wanted to have say 5 screens with less wallpaper scrolling when you transition from screen to screen...then you could implement your division tables as stated in your original post. It really functions no different than a desktop with multiple monitors....other than the fact that you have one screen and wallpaper scrolling on the Android device.
EDIT:....I guess I have been working too many hours....totally forgot about the fact that you have to crop images when setting your wallpaper. That being said....stick with 640X480. I am gonna go punch myself in the face now.
Size of the background does not matter. The ssytems will scale it when you choose the wallpaper. Or you can manually select what you see in the gallery.
If you need the background to look a specific way then yes the size matters.
Since the system will stretch or shrink as needed.
Proportion is more important. 640x480, 1280x960, 800x600 They will all scale to the same appearance.
As for screens:
What changes is the amount of the background that shifts.
On 3 screens the left screen see 0-50 of the picture, the right sees 50-100 the center screen sees 25-75.
On 9 screens: These numbers are off because it actually takes like 6.22 or something but this is close.
screen 1 = 0-50
screen 2 = 6-56
screen 3 = 12-62
screen 4 = 18-68
screen 5 = 24-74
screen 6 = 30-80
screen 7 = 36-86
screen 9 = 42-92
screen 9 = 50-100
I would be impressed if someone can figure out a way to make each screen a different wallpaper. A single image would be fantastic but probably unlikely.

Launcher Pro has a stationary-wallpaper option.
So i have been trying to get a black background that is truly black.
everything i have tried has left a slight hue on the background. back 2 black is not supported or i would have tried that.
is there any way to get background to remain off completely and only light the pixels for the icons, clock, notification etc etc. i notice the info bar at the top is darker than my black background and no matter what i cant get the background to go completely black.
my reasoning is if i make the icons into line art, and keep as much of the screen off wherever i can i can stretch battery life even further. it worked wonders on my gs2. But having a slightly glowing background ruins all that.
I'm not sure whether it's supported, but you can try making a monochrome bitmap-file (.bmp) in MsPaint. At least you are sure this way that the black is truly black.
Have you tried using different launchers? Are you sure the hue is not just your icons giving some 'bleeding'?
thanks, i will give that a try.
its the same with go launcher and touchwiz. its actually magnified on the lockscreen showing lots of banding.
Try this pic. I use it on mine and looks black

My first Note did this so I sent it back. My new one does not do it.
still no luck, apps with black backgrounds look fine.
i tried an all black bitmap and that didnt work either.
is there any way to turn background off and just leave it blank? would that give me a pure black background?
like i said i dont think its a hardware problem since the app backgrounds look deep black unlike the wallpaper. i did see something about the note only being 16 bit and that was causing weird display issues due to scaling or something, blah blah.
its using 24bits
thats right, the note is 24 bit and the os operates in 16 bit currently, right? either way i need to find a way to fix it.
I used a plain black GIF. Works fine for the home screen background, but on lock screen it has barely noticeable dark gray lines in it until you touch it and the unlock symbol appears.
here is the one i made
this black is one color 24 bit png on my note it is completely black at any brightness. let me know if it works. 800 x 1280 black correct dpi blackground

or download "no wallpaper" from the market - simple app that just adds a wallpaper that is totally black. Works a treat.
Try an app called COLOURS by Tim Clark
Hi to all.
I cant find a solution to my problem and maybe someone can help me.
I have found some wallpapers for our Note in the right resolution (800x1280) to use these in my lockscreen.
The problem is that when i choose a wallpaper with lot of black color and choose it as lockscreen wallpaper i can see some horizontal lines on it.
If i choose the same image as phone wallpaper everything is ok.
Where is the problem?
Thank you all.
I have the exact same issue. Horizontal lines on lock screen, but looks fine everywhere else. I don't have the solution, but maybe I can help you out a bit.
I did some searching, it turns out that there's some sort of software bug that doesn't allow black images to be truly black but rather very dark grey. The thread is somewhere in this forum.
Also the native lock screen resolution is actually smaller than the screen resolution because of the notification bar. Per this forum: http://androidforums.com/htc-hero/37268-lockscreen-resolution-compression-issues-false-info.html
Also when you set an image to be the lock screen, it seems the picture is re-scalled and saved again (in another directory), which means compressed again.
Android phones usually don't display images in 24 or 32 bit color but rather 16 bit color, which means color banding. More on that information somewhere in this thread also.
My suggestion is:
1. Find out the native lock screen resolution. I'm also searching for the figure.
2. Edit your photo, change it to that resolution, and make sure the black areas of that image are truly digitally black (000000), and save it as an uncompressed image.
Maybe the horizontal lines are because the image is being re-scalled, re compressed, and the image being displayed at 16 bit color with a "true black but" is resulting in horizontal lines.
The solution is this. I'm using it and black is perfect.

Not bad idea at all...I have used widgetlocker in my previous phones but somehow i had some little problems like small lugs or battery draining.
I dont know if in the latest version is fixed.
But ill try cause i love black lockscreen in our huge super screen...
edit:Not working properly for me cause i have lower destiny...
Ah, what a shame! But WL does work, so if you ever go back to the stock density i highly recommend you using it.
Magick locker is free so you can test that, get a theme and customize wallpaper, set any black image and its fine. so its samsung lockscreen software bug
One simple solution, use wallpaper wizardrii!!
It solved all my wallpaper problems!
Wicked app & highly recommended. Link - https://market.android.com/details?id=com.twistedapps.wallpaperwizardrii&hl=en
Functions of wallpaper wizardrii:
Wallpaper Wizardrii, "Changing the way you set wallpaper" ™.
Twisted Apps just bought an Asus Transformer to make WW work for tablets. We have a beta so if you want to try it e-mail.
Set your own images, Portrait, Landscape, and Crop; all with No Scroll or Scroll. Check out set Exact or Crop Exact! Set images from WW, file browser, or Android's Gallery (Share as). Check Home App compatibility with No Scroll option (only).
The Nexus 4 display allows for significant variations in its colors, all you need is root(;
So therefore I decided to make this thread, to see what others people setting are, currently my colors are set to 255:240:221, I like it very much because it makes by brighter colors such as red and orange stand out a lot, but what are your color settings?
Post Below
P.S.
If you want to compare your color settings to some one else's I included a few images below, you can screenshot them and post them below with your color settings, after that you can easily see how different the display looks
There is actually already an enormous thread with a spreadsheet of everyone's values. Also, everyone's screenshot will look the exact same since you're changing the properties of the screen, but not the image itself.

Hi.
Whats the stock setting on cm10.1 ?
Thx
Just a pet peeve of mine; the UI on Pixel 7 in dark mode isn't actually black, it's more like a grey or brown depending on what style you choose. Makes it look like an LCD not an OLED. I've attached 2 screenshots of app drawers to illustrate. One is from my Pixel 7 which isn't exactly black, and the other is of my Galaxy A53 which is pure black. Just looking to change that if possible.

I bought Nova Launcher Prime a couple years ago, may as well use it. But for what it's worth this option should come stock.

You are welcome to try this if you are stock-rooted. Flash in magisk app.
The drawback is that upon rebooting your phone, your phone relocks itself (not reboot). When you unlock it the second time, the mod takes affect. Without that post script, the phone would bootloop. This happens everytime you reboot your phone. Because of this, this mod is incompatible with the magisk module that is a "bootloop protector" as it sees this mod as bootlooping instead of relocking and disables the mod. This mod is using cool_modules installer from here:

I tweaked it to use with Pixel Launcher.
To get your settings background black, you go to settings/ display/display theme and choose stock-black.
Might be worth a shot.
Also repainter app has this feature.
The reason why the color of the dark theme is not black but something similar to gray is because when you move white text on a completely black background, an annoying color plot is perceived due to the delay that the screen pixels have. OLED to go from completely off to on, and it is precisely here where the grays fulfill a very important task, since they generate a contrast that "hides" the phenomenon described above.

So Google is using inferior OLED panels? I find my A53 has a much nicer screen & no issues with text in black background scrolling.
I mean, look at the fingerprint. I don't understand how this is a "Flagship" UI. My A53 is slower for sure, but the UI has nice blur effects, pure black backgrounds, the fingerprint isn't an icon; it's a pure white translucent fingerprint. I just expected better. I don't feel like rooting it and bending over backwards to get it to look decent. I put it up for sale and no one wants it. Will trade it in at Best buy for a discount on a Samsung. The pixel 7 takes great pictures, it's fast, but the battery life is mediocre and The UI is too bland for me; it's washed out.
