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.
Hello there.
When I installed ICS (RC4.2) to my Galaxy S (GT-i9000), I noticed that the screen's gamma value had changed just enough to make all the colors look a bit darker. I know it isn't really that big of a problem, but I'd prefer to have the gamme value back to what is used to be. So I'm asking if there's a way to change the gamma value back to the way it was in, say, in Android 2.3.3?
I did a quick search and couldn't find any solution.
Thanks in advance!
sure dude, you can download Voodoo Sound App from market, you can manage gamma colors from there
it works for me
I have currently CM12.1 rom installed on the Fire thanks to ggow and everyone else who made is possible and loving it. The default font seems ok because of the low res display. Has anybody any font suggestions for better font readability (like better hinting or something). I know the display is kind of weird on this one, it appears that it squezzes the display in vertical mode and expands it on the landscape mode.
Only seen people mention changing the dpi to get it to look better, hadn't thought about simply changing fonts.

I tried Segoe UI Semilight (Don't hate on me just because it is Microsoft related, Segoe is my favorite font ever.), but it was very skewed and not clear at all. I have to agree with you that the default font is the best for it in all honesty.
i'd stick to chaging the dpi setting, it will look less as a tablet and more like a phone but the overall experience es better. and let's be honest, with 1024x600 it's better this way. i currently have mine set to 200dpi
Hello
I noticed that after installing beta 14, colors are awful, they are not as vibrant as they were before, what can I do to adjust them?
Move back to Stable build or an older beta build because as of OB14 the default color profile will be less vibrant and it's really good and accurate now red are red instead of that old neon colour.
Read the changelog before flashing. The colors are not awful. They are better.
They could have left one of the choices in the screen calibration settings as the original saturation. Something like default, sRGB, vibrant, and custom. I personally liked the vibrant colors, with the deep blacks it really made the AMOLED display pop.

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.
