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.

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.

I've resized many images for my lockscreen perfectly, but every time I set one, they get horribly decompressed.
Is there a workaround for this?
Attached is what I'm talking about.
Just making sure, is your image 320x455?
And in your screenshot, should we be looking at the artifacting in the background? Or something else? Because it looks like that's present in the whole image, in the lock bar and the notification bar too.. just a result of jpeg compression.

Yes, size 320x455.
I've attached the original for comparison. A lot of the red around the gun is distorted, instead of the smooth quality that it should be.
The problem is, or I think is, the phone compresses images no matter the size for lockscreen wallpapers. When I set the same image to my Home screen background, it appears perfectly fine.
So, would there be a workaround for the lockscreen wallpapers?
Anyone?

Not familiar with this but look for someone named impaler, he is into themeing and such. If he doesn't know he may be able to point you in the right direction.

You might want to try an app called 'CropWallpaper'. I use it for my wallpaper, but you may be able to use it with your lockscreen. I'm on CM6 right now, so I can't check how it will work with sense, sorry.
I think you need to size it for the actual screen size of the Hero. On the home screens it is larger because it has to scroll through several other screens.

No worries, and thanks for the suggestion. Sadly it didn't work. But it's handy for normal wallpapers.

That didn't work out well either. The exact size of the screen is 320x480, 320x455 is when you take into account for the notification bar.
Sadly, there's no current fix for this ( that I've found ), if anyone else reading this thread comes up with something, please post.
Thanks to everyone who has commented thus far and to theimpaler747 for trying very hard to help. I really appreciate it guys.
I know there was another thread similar to this, but this is getting kind of annoying. Android seems to assume that your device is portrait and when setting up wallpaper, this is apparent. The majority of wallpaper I've tried have been cut off one way or another, most annoyingly is the one I wanted to try today. Absolutely unusable.
http://content.wallpapers-room.com/...com___Matte_Wide_by_SaizenMedia_1680x1050.jpg
When I saved the image, looks perfect. When setting it up for wallpaper, the sides looked to be cut off, no problem. That's tolerable. When I actually applied, I barely got the top half of the image.. lol
I know android isnt really built for tablets just yet, but there has to be a better way.. if someone has an idea and I have to write an app for it myself, I'll do it... lol I can't be the only one bothered by this.
Actually i kind bothered with a similiar question.. i read wallpapers should have 1024x600.. then i made some of my own. NOW i cant apply them. Stupid androind always asks me to crop them, so they look horrible. Dont know how to apply a simple wallpaper. Anoying...
Thank goodness it's not just me!
Was having the same issue, but thought it was just me. For the life of me I couldn't figure out why all of my images looked borked up whenever selected as wallpaper.
Download multipicture live wallpaper from the market. I use this and am now able to see high res wallpapers in their entirety. You can set it up so that each time you swipe between home pages a different photo is shown but I just have one photo as my background.
I really have searched alot for this answer. I run a CyanogenMod based ROM on my HD2. When I go to select a wallpaper there are four options; Wallpapers, Live wallpapers, Gallery and CyanogenMod Wallpapers.
Ignoring the live ones for a moment, when I select a Wall from the Wallpapers or CyanogenMod I'm not asked to resize/crop it and I get a lovely sharp Wallpaper on my Home screen.
Selecting a Gallery image I am asked to resize/crop it, even if it is already the correct 960x800 resolution. And no matter what I do the resulting image that appears on my home screen has lost lots of detail.
Thinking some redundant rescaling might be happening, and considering the original sources of the walls were higher resolution anyway, I made bigger images which still had the correct aspect ratio. I was hoping they would retain more detail but no, it's like the images are sized down to a resolution below 960x800 and then scaled up for displaying on the home screen losing detail in the process.
The quality drop is nothing like what Sense used to do on WinMo, it's quite subtle, but it's definitely there.
Anyone else experienced this, any solutions
Note. I've also tried Nexus One based ROMs on the phone and got same result.
The remedy you're looking for is called "Wallpaper Set & Save" and is available on the Market for free.
Make sure though that your Wallpaper is in a 4:3 aspect ratio (640x480, 960x800) and you can set wallpapers in full quality.
As far as I can tell, pretty much everyone who in some way customizes his mobile phone is using this piece of software.
Hope that helps
Wallpaper Set and Save in the market.
Cheers guys, that worked like a charm
CAn someone upload it here .. CAnnot found on market .. mini pro.

this will blow your mind on how crystal clear the wallpapers can be when we use native 1024x600 resolution. this is not some blown up 480x800 blurry wallpapers we always see to acheve wallpaper scrolling wich I always have off cus it lags my scrolling
1. download multipicture live wallpaper
2. download a highdef wallpaper here wowallpapers.com/show_wallpaper/world/england_wallpaper_01_1024x600.jpg
3. go to live wallpapers and select multipicture live wallpaper
4. go to common settings - picture source - single picture and select the high def pic
5. then select crop resize ratio and select Show Entire Picture
6. go back and under drawer settings select transition type and select None.
7.go back and under picture folder selection uncheck double tap to change picture
8.then go to picture change interval select Never
enjoy the most unreal wallpaper on your nook. if u have adw select landscape oreintation only . because potrait kills the wallpaper
Or just check the long-standing steps posted in the OP of a stickied thread in this very forum There is a quick & dirty solution there, but also my steps to get a pixel-perfect wallpaper.

PS: 1024x600 is too small. You need a bigger image than that if you want to have it move in the background a keep an un-stretched image. We use the same size as the Galaxy, which is 1200x1024. That seems to give me the best results.
that method involves cropping the picture. my method SHOWS THE WHOLE 1024x600 picture (no croping)and its a tottaly diffrent way of the one that's posted on there. and I also mentioned I dont like having the wallpaper scroll at a cost of performance. if u wanna do it your way by all means I'm just sharing my way of doing things. cheers

Well you only need to crop the image if it's not the right size already, which is true of any method of setting a wallpaper, including yours. Not to mention that your method breaks in 50% of supported orientations Hardly "tottaly diffrent..."
And I have no idea what performance hit you are seeing from having a scrolling wallpaper. I've had no issues at all on Android 2.1 or 2.3, both at stock or with an OC'ed kernal. I mean, you're of course welcome to use whatever settings you want, I just dont know what performance hit you're talking about.
Either way, this just seems like a bunch of extra steps to accomplish the same thing that has been posted previously, just with less functionality. I dont mean to sound malicious; I just dont understand what advantage you're offering people.

You are a genius cowballz69!!! Not only did this solve my problem and keep me from having to crop, resize, etc, etc, it also allowed me to have random wallpapers, different size wallpapers, etc. And they all scale excellently and look wonderful on my Nook Color! I was even able to mess around with the program settings and get an accpetable workaround for the wallpapers in portrait mode. (I have the mirror effect above and below the image, looks nice.) Thanks again!
Is this 1-1 pixel mapping when done either way?
I haven't even tried putting a wallpaper on other than the defaults yet, too busy exploring other NC features.
I tried every single method out there, this was the only one that really came out nice and crisp. Thanks man.
After reading up, i also tried ES File Explorer's Wallpaper function and got very good results, not as good as your method, but i would prefer to not run a live wallpaper if possible and got good results. I hope a surefire solution to this wallpaper situation shows up for the nook one day. I force the nook to landscape btw.

I just tried Wall Switch with 1024x600 wallpapers and it still insists on cropping and otherwise adjusting the pics.
edit:
On the subject of the thread, I'm kind of surprised that this hasn't been fixed yet. Usually you guys jump on wallpapers and themes right after root.
I don't understand why the settings aren't built in that will allow us to just go choose a 1024x600 image, apply it in the correct orientation, and not let it move no matter how the screen is tilted. I don't want my wallpaper to scroll or change at all. That seems like it should be easy to do.

I followed this to the letter, picture came out cropped severely.
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.

I dont know if in the latest version is fixed.
But ill try cause i love black lockscreen in our huge super screen...

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
