Hey guys,
I noticed something weird today and was wondering if anybody else had experienced it.
I was viewing wallpapers through my phone's browser and they looked fine. When I saved and applied them, however, they displayed incredibly strangely compared to how they looked in the browser.
The only way to describe it is transitions between colours have lines between them, like contours on a map. This doesn't happen with any of the default wallpapers so for comparison I downloaded our default rainbow wallpaper and when that's applied manually it also has these weird color transition lines. It's pretty ugly.
I tried transferring the wallpaper across from USB and it still had this effect.
Has anybody else experienced this? Everything displays fine in the browser but as soon as it's applied to a wallpaper it goes strange
I do!
sometimes i set a wallpaper and some time after it gets strange, like with some squares on all of the wallpaper.
No such problem. I change wallpapers very often, from various sources.

I've just found a solution for this on my HD2 running an Incredible S ROM and came across this thread whilst searching for the problem, thought I'd post here in case anybody is interested.
The HD2's screen has a color limitation, whilst the Legend's screen is AMOLED - both panels cause an image display problem known as color banding. As the OP described, it's when gradients appear chunky, "like contours on a map". For an example, see this image.
As I used to own a Legend, I was frustrated with how wallpaper images I applied would look like that - all except the stock HTC wallpapers. That's how I realised the fix for it.
If you're rooted, you can replace one of the standard HTC wallpapers in your ROM.zip's system/customize/resources folder. For example, I had a custom image I always used as my wallpaper that looked crap on my HD2. I replaced HTC_wallpaper_03.jpg in the folder I mentioned and, when applied through the default HTC Wallpaper options available from Sense's home screen menu, the image is dithered and looks perfectly smooth.
So if anybody else wants to smooth out a wallpaper you always use, just place it into your ROM's zip file and it'll be fine.
Hope that helps someone, someday.

(First, I'm trying to avoid HDwalls)
It has always bugged me that when you apply a wallpaper under Settings, that the wallpaper isn't as clear as if you were to view them in the "Picture" tab. In fact, the applied wallpaper is some what blurred at a lower quality.
Has anyone noticed this? Or is it just me because I can point out something you were not able to see.
try it yourself with some sharp jagged text as wallpaper. Then apply it to the lock screen as well.
You'll notice that the wallpaper on home screen is not as crisp and clear as the one on the lock screen.
Anyone know why?
you are right, I did notice this.
has it got something to do with the phone trying to squish the image into the right ratio instead of just cropping the image too fit?
not sure maybe some other members can offer their help?
See, you didn't even notice youself. And i think most people dont realize this as well.
Anyone got a fix?

Sense resizes the image to something smaller than 480x800 and then stretches it again (for some silly reason). It's a long-known problem - since the phone was first released. It's also one of the reasons that HDWall came about. The only alternative to HDWall I know is to install Co0kie's Home Tab. You can set wallpaper with that and it retains the original quality (as well as having a LOT of extra wallpaper options).
Try resizing or cropping the image to 480x800 then setting it as a background, that way the phone won't need to resize it for you.....

It still does it. The default way of setting wallpaper in Sense is just crap.

cookies wall doesnt work. never did.
home tab>menu>home wallpaper> etc...
that path doesnt work.
unless there is some other way...
resizing images dont work either.
I just also want to mention that Cookies Home tab 1.8 does improve the quality of the wallpaper over normal Sense BUT they are still reduced in quality and resolution somewhat so are still not full quality.
So for me - HDwalls is what i use - though i sometimes have trouble getting it to work properly.
Use SPB Mobile Shell. You will get mega sharp wallpapers (custom of course) and far better functionality than standard sense.
I got a problem. I've installed Hyperdroid1.7 on my energy rom HTC HD2. But it seems i cannot apply a whole wallpaper. When i select a wallpaper from the gallery ... i see the picture on full screen but there is a little crop window you stretch to only see a portion of the photo. Any ideas how can i fix this ?
Thx
This is normal. Select the whole picture.
Try "Wallpaper set and save" from the market (free). It's a much better way of setting wallpaper and fixes the colour & resolution issues that many people complain about.
For some reason, a wallpaper with the same resolution looks fine on my computer looks absolutely grainy on my DHD as wallpaper.. especially the smooth gradient of colour becomes layers of colour transition.
The quality/stock wallpaper on my phone looks completely fine, I was wondering is there a particular optimization design to be use as wallpaper on DHD.
many thanks

Download wallpaper set & save from the market, this should eliminate the grainy gradient on the wallpaper.. The phone compresses the image so that it uses less ram or resource for the wallpaper, with wallpaper set & save, the compression is reduce to retain the image quality..
I see, but what if its my custom wallpaper, is there a work around?
EDIT: sorry, i mis-understood what you mean.. I will download the tool and have a go!!
That tool hasn't been updated since android 1.0.. omg. I can install it but it doesn't work

Tried another app, wallpaper wizardrii, still the same. it compresses the wallpaper.. while it doesn't on the stock ones, very strange..
Wallpaper Set & Save works perfectly for me. For best results resize your pictures to 960x800 on your PC first.
Many thanks for the tip, but I figure that out as well
Hi, most people already know this but it doesn't hurt to mention it now and again for newbies.
If your wallpapers look terrible when you apply them using the stock gallery app, ie they look like they are showing in the wrong bit depth, this is a dithering issue, stock gallery doesn't apply dithering to smooth image. To resolve simply apply your wallpaper using something like es file explorer, takes a couple more key presses and you cannot resize but wallpapers look perfect.

i use it before with galaxy s, work great too
What about live wallpapers? That seems to show some banding and stuff.
I was wondering if anyone could help me out with a wallpaper issue I am having. I downloaded some 960x540 (or 540x960) wallpaper images and when I try to set them as the wallpaper using the stock ROM's cropping tool, the cropping tool displays the wallpaper image very large so that you are only able to crop a small portion of it to use as the background. I am wondering why it should not just be able to crop the entire image because it is the exact same size as the screen? Another strange thing I found was that sometimes I use Zedge to download wallpaper and they are not the correct size of the display and are usually larger (i.e. 800x480), but they show up smaller in the crop tool and I am able to crop a larger portion of them. Can anyone tell me how to resolve this? For now I am using an app called Wallpaper Changer which witll set the wallpaper to fit the screen exactly, but I kind of didn't want to have another app running for this. Thank you in advance!
I would l like some info on this too. Same issue here. Downloading correct resolution image but only able to display a chunk of it.

This is actually the Android OS's fault. Because Android is made to work in both Portrait and on Landscape (even if your launcher locks orientation), selling the wallpaper will encompass both. I ran into this problem myself when I went to make my own wallpaper. The easiest solution is to find a square image, preferably 960x960 or larger. I've included the wallpaper I made and how it looks on my phone.
