Display banding/striping issue

I can't take a photo of my screen but I clearly see horizontal banding in black-on-white text pages...they're like this:
text-text-text-text-banding-banding-banding
text-text-banding-banding-banding-banding
text-text-text-text-text-text-text-text-banding
and so on...sorry for this weird explaination but couldn't find a way to describe them since english is not my mother language....
those stripes are white, more white than the page background...
i took a screenshot, and viewed it on the pc...no white stripes there, so it's not software related ...
anyone else have/had this issue????
send to htc is the only solution? (obviously it has unlocked bootloader)

yes this has been discussed before. the best example is when viewing google's forums, you can see alternating bands that line up with all the text rows. and in between is pure white, while the text rows show slightly darker.
that's just the way it is for now. no fix has ever been released.

thanks for the answer =)
so is my phone defective or is it like that for every nexus out there?
EDIT: sidenote-to me it's the exact opposite, the stripes where text sits are more white than the rest of the white background that is a little darker

[Q] White or Black background?

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.

[Q] All Black Everything

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

Ok, i still think you should try mine, it's black lines, white text inside, near black top selection, only thing not are the right downtime with all the letters i think Marsou77 has implemented it in his prada theme

shure,give me the link and i will try and when i like it build in one of my Roms maybe;-)

Grey mark, bottom right?

What is this?

No idea. Is it always there.

It was, though I could cover it up with apps... Led me to believe it was something to do with the wallpaper. Changed it and the grey spot is gone. Odd.

It's not there on mine.
I've changed my device's wallpaper and that area of the screen shows the wallpaper that I've selected - try changing yours and see if the grey mark disappears.
