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

Dear Xda Community,
i recently swichted from Hermes to Kaiser and I have one issue with my wallpaper. Its some kind of semi transparent and I dont know where I can change the setting to be not transparent ?
Greetings
fire
go in file explorer and open the file you want to use as your wallpaper
then go to options and click "set this as today wallpaper"
then on the next screen, click on the transparency % and reduce it to 0%
hope this helps
I had this same issue... But even after setting it to 0% transparency, it still looks goofy. The color still seems lighter, and it's very grainy. I made the image on my desktop and cropped it to 320x240. I can't figure out why it looks so bad. Any ideas?
Post it and let someone else try it.
I think my problem has to do with the image size. If I look at the image in the picture viewer, it looks great blown up to fit the screen. but it's also a different size.
When I set it as my today screen, I think it's squeezing it to fit between my task bar at the top and the menu bar at the bottom. So if I create a new image that is the right proportions for that area, would it look better? What is that area?
I'll try to get a screen shot up here in a bit.
Here's a side by side screen shot via myMobiler.
On the left is my today screen, on the right is the same image displayed in the image viewer. These are very good representations of the difference on the actual phone too. You can see what it is I don't like the best if you look at the gradient from the orange to yellow around her knees.
Is my problem just the format I used for the image? I just noticed I saved it originally as a .gif. probably would work better as a .jpg or bmp I assume
well, ok, so it doesn't show as much after I had to lower the quality to get it to upload... site contstrints made me drop the jpg quality down.
Yup, saved it as a .BMP and set it as the wallpaper. Looks way better now.
So, maybe its just me, but i notice that my nook, on any rom, does not seem to do well when displaying images that have subtle gradients. i have attached an image that i wanted to use for my background - it looks great on screen, but like crap on the nook. Anyone else notice this? I love the screen in general, but looking at that image makes it feel like i am using an 8-bit screen...

I've found it can display images fine, but that when setting it as the wallpaper it messes up the gradient and also tends to make the image blurry, as though its changing the resolution (despite the image being 1200x1024 or whatever its suppose to be(possibly 1024x1200)
Color Banding with live wallpapers enabled
Hijacking this thread.
Is anyone else noticing color banding on NC with live wallpapers enabled?
For example, take a look at your desktop with the two settings:
1. Livewallpaper + analog clock widget
2. Regular wallpaper + analog clock widget
The clock displays horrible banding in test case #1. I tested this on 7.0.3. stable and several nightlies since. I've see a few posts on this in the other device forums but most of them seem to be issues with the supported bit depth of the actual screen itself or wallpapers in general so I wasn't sure if they were applicable.
Is this an Android issue or an issue with the rom? Something else?

I recommend Wallpaper Set and Save, free in the Market, to fix that problem.

It's a funny old app, made for Cupcake I think and hasn't been changed since then. The UI is small and kind of odd looking. Changing the default settings won't stick on my Nook Color. It really wants your wallpaper to be in SDCard/wallpapers. So it barely works, but it does make wallpaper look better.
Thanks for the suggestion. I've tried that app before but it looked like it was only for regular wallpapers (where I'm not really seeing the banding)? That or I'm dense and overlooking something.
Also where are the stock wallpapers normally stored on cm7 install?

You know, there were a lot of people who noticed banding on the HD2 roms, and it did seem to vary between various roms. I never really noticed it (perhaps I used the good roms), so didn't follow it much, and couldn't say if there was a fix. But, there should be many threads on it in the HD2 android section.
I've also noticed pretty severe banding in gradients for both jpeg and png images.

As said, use something besides Gallery and it'll look fine. I use Wall Switcher and have some 20 jpg's in a directory and it switches 'em every 15 minutes, but there are lots of options.
It's not the NC, the ROM... it's the app you're using to set the background.
Just to clarify, the entire desktop starts exhibiting banding (icons, Widgets) and not just the desktop background. Almost as if the os is switching color depth. Can you guys reproduce this on your cm7 installs? Maybe I need to post screens or something.
This ONLY happens when I select a livewallpaper. Regular wallpapers dont affect the widgets and desktop icons like this. If its a matter or how im setting the live wallpaper, How do you set a live wallpaper using gallery or any other apps? What directory are they stored? Thanks.

7 replies and not one person mentions that the nook's screen is only 16 bit... of course there will be gradients, its a small issue and when I noticed it with a space themed background went ''meh'', and used a different one.

Ah. Well that would make more sense. I always thought the display was 24-bit because people are always comparing it to the Ipad screen. The clock does look distractingly bad though haha...maybe I'm just anal.
Just added some screenshots using the Grass Live Wallpaper versus one of the stock CM7 ones. For posterity.
Go to the app store and download "Large Image Viewer" it will solve all your problems. The nook color screen is an IPS display, the same as the ipad and much better than other andriod tablets. Large Image Viewer is a very fast hi res viewer and no, I am in no way affiated with them.

Errr...thanks but how is that related to this thread? haha
Dalingrin's OC kernels are 16-bit, stock is 24-bit. It's about that simple.
I campaigned for a way to switch live, and at one point he considered just such a kernel mod but I don't think it ever went anywhere.

Finally some info related to my question. Going back to the stock kernel fixed the banding issue with live wallpapers. Thank you! If anyone else is interested...details are in the OC Kernel thread (search banding, color bit depth, etc.). Wish this was explicitly stated in the OC kernel OP.

I'm noticing the same thing. The screen seems to handle gradients in regular wallpapers fine, but gradients in Live Wallpapers look horrible. Like someone stated it's like it's changing bit-depth. I'm on a stock, totally virgin Nook Color. Does anyone know how to work around this? I'm building Live Wallpapers and what looks fine on other devices looks terrible on the Color.
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
I can't seem to use a static wallpaper that fills the screen in portrait mode. If I try to add my own from a hi res picture it hangs for a few seconds then returns to the standard green leaf background regardless of which paper I had selected. The standard ones aren't big enough to fill the screen. Live wallpapers are fine though and fill the screen. Has anyone else noticed this and is there a work round?

Same here. I got CM10 installed and managed to get a nice full-screen background made from my gallery that was downloaded from Interface Lift. It is VERY annoying, as the standard backgrounds are smaller than the 1920x1080p screen, so I'm left with a black screen.
Any help would be appreciated!
I'm trying desperately to love my android device, but it keeps tripping me up with stupid things that I swear shouldn't be this difficult.
Latest issue is that I have a gorgeous 1080x1920 wallpaper that I would like to set as my background. Considering the M7 has a 1080x1920 resolution you'd think that this would be a match made in heaven, but NO for some reason both the gallery app and es file explorer are forcing me to resize the wallpaper to some awful square resolution that kills the quality of the wallpaper.
Reading around I understand that this may be due to the wallpaper scrolling feature, but if that's so I'd just like to switch that feature off and have my background be static. Can I find such an option....nope.
So please, someone put me out of my misery.

Funnily enough I've downloaded that and a load of other wallpaper apps and none get it perfect.
With the app above, if i select a 1080x1920 wallpaper and tell it not to resize, it looks perfect in the preview, but as soon as I apply it, there is a 15mm black border at the bottom of the home screen. It's almost like its reserving some space form the 3 dot menu.
It's driving me f**(^ing insane. I cant believe android is so retarded. Even Windows 3.1 could set a bloody wallpaper full screen.

Let's keep in mind that it's not Android that's stupid, it's Sense (at least parts of Sense). Stock Android/CM/etc can set full res wallpaper images without issue.. You could probably even set a full res wallpaper with a 3rd part launcher
