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.
Hey guys just installed cm7.0.3 on my new nook color last night. I noticed today theres some pretty bad banding on it. For instance, if I open up the stock android calculator app, the buttons that have numbers on them have a clear distinct line about halfway down where as on my phone (nexus 1) it's just a smooth gradient. Is there a way to fix this? It's also very noticeable on the music widget
Hello everybody,
I have an issue with color clipping on the actionbar in every app that uses it (e.g. Gmail, Google Play, ...).
After marking items and the actionbar changes there appears a color clipping issue (see attached screenshot).
I got this problem with Stock Sense 4.1.2, Stock Sense 4.2.2 and even now with CM 10.1.
I haven't ever changed anything that would cause this behaviour. Stock Sense 4.1.2 was non-rooted and had this issue.
I already checked my dpi settings and they are correct: 480 dpi.
I hope anybody can help me with this. What could be the reason for that? How can I solve this?
Thank you all very very much in advance!
After flashing custom roms such as L-droid and AOSB 1.3.7 , everything works fine except for messenger apps which now shows hyperlinked text (typed phone numbers/weblinks/emails) in white. This is problematic as the white text becomes hard to be seen with the green and white chat bubble of whatsapp.
Other apps experiencing this problem includes facebook messenger.
This problem is not found in Gapps such as gmail and hangouts where phone numbers and hyperlinks are still displayed in blue.
Its a very peculiar problem which i can't find solutions anywhere. my hunch is that system font style needs to be changed.
Tried changing style using themes from CM theme showcase, problem persists.
Can anyone point me to the file that needs editing or any solutions available?
Hi all, I have an AT&T Galaxy Note 5. I was wondering if anyone has played around with the Theme Store. It seems after I applied some themes (Material Design, etc.), it reverted my dpi so that I see bigger home screen icons (the icons had been smaller). I immediately switched back to the Default theme, rebooted, etc. but the big icons stuck. I painfully wiped the cache partition and even factory reset the phone.... still bigger icons! Anyone else have a similar issue?

I don't have the phone, so I can't say I've had the issue, but have you tried checking if the actual DPI has changed? If it has, you can change it without root at the link below. I've used this method before and some samsung phones will have camera issues when changing the dpi. I believe the stock dpi is 560. Hope this helps.

I installed Material Dark and the DPI didn't change.
Thanks for the link to check. I'll do that and see what I get and report back.
Screenshots?
Likely a stupid question, but are you sure it didn't just reset the grid layout to the less dense grid?
Looks like it maintained the density. Guess my eyes just play tricks on me. Screen grid remained 5x5
