I was just wondering if a white background would consume more power than a black background for the theme settings.. Anyone have any thoughts on this?

Depends on what phone you are using. The samsung and dell with their samoled screen consume more power with a white background. The htc phones are using s-lcd which means it doesn't matter if it is white or black. I prefer the white background on my HD7 it looks nicer.
Oh cool.. Im using a HD7.. Was using black in thinking that it will prolong battery life.. Now that you mention that, i'm switching to white =) Thanks =)
Black looks best.
I like black but it annoys me that the fonts on black look horrible. For instance, in settings, the small fonts distort when scrolling up and down. This doesn't occur on white. Nor does it occur on the Omnia 7 even when on black. So perhaps this is a HD7 issue, or perhaps it is just my HD7. Am interested to know if others have noticed it.
I hadn't noticed that. Now I'm bugged by it. Thanks.

LOL.. Infectious thoughts.. =)
On side note does anyone have their notification LED on when there's a text message? I only have the LED on when i have missed calls..

Could you elaborate on this distorting text? I haven't noticed anything on my HD7 with black background. Text looks wonderful on this screen and Windows Phone 7.

just open the Settings page and scroll up and down slowly. Notice how the small subtext is a lot tougher to read while scrolling. That's what he is referring to I believe.
The text issue is called "ghosting" and is due to the low quality LCD panel on the HD7, which has a very low pixel response time.
It bugged me a lot on a black background. It's not noticeable on white.
Yep, as the other guys say. A better description than my original one is that the text has a "shimmer" when scrolling. It sort of fades out.
Rather than it being a panel issue, I think is might be a cleartype or font smoothing type of issue. Later on I'll do up a bitmap image with some text on it, and see if the problem occurs. If yes then it's a crap panel and if no then maybe fonts/cleartype/software and hope.
Another problem with the black background is you do see the backlight ever so slightly. Yes, I knew this, when I (now somewhat regretfully) chose it over the Omnia 7. Be good if Microsoft gave us more colour options, I'd probably use a very dark grey if available. My £99 ZTE Blade has far nicer blacks than my HD7 Sorry to rant. No need to flame. I think the HD7 will be the great WP7 hacker/modder device and this alone is enough for me.
I created a bitmap and emailed it to myself. The shimmering effect did occur when moving around. So it does seem like a screen or a screen driver problem, and nothing to do with fonts and the like.

I thought it was because grey on black has less contrast than grey on white. Could you do the same but instead of grey use white.
I have just again compared the scrolling of the settings page on my HD7 with my Trophy and there is a huge difference!!
On the Trophy's SLCD screen there is no ghosting and everything just flows and stays readable all the time.
Everything is just so much more vivid and vibrant on the Trophy !
It is indeed a shame that HTC have not used a SLCD screen for their flagship model
I've stayed with white I tried black for a bit but it did not look as contrasty as hoped.
Sorry tbk21, I can't try it as I sold the phone. Got loads of interest on Gumtree. HD7 is not the one for me. The speakers, the screen and the slow loading of sdcards. Sticking with my clunky Android for now. Maybe I'll be back for the second wave of WP7 phones.
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.
https://market.android.com/details?id=com.android.wallpapersetandsave
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
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

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!
