Hi,
I recently got a used HD to replace my Hermes and started flashing new winmo 6.1 and 6.5 roms aswell as the latest 1.17 radio, after flashing HSPL 156Olinex.
After looking at some pictures on the HD i was suprised to see really strong color banding in some pictures.
Please have a look at this sample picture of the HTC gallery:
I see really strong banding in the dark green area of the stem of the flower underneath the yellow head.
Also a lot of standard background pictures eg the standard grey circular gradient of the manila interface show banding "rings".
Recently i flashed the Rom Topix 3.2.2 and observed the a strange effect:
After an Hard reset, during the configuring process of the first boot up a orange windows mobile screen with a circular gradient is displayed. at first the gradient is smooth and just before the first stylus calibration the screen suddenly changes and the circular gradient is now broken up by colorbanding rings.
I do not know why i did not see the banding problem at first sight before flashing anything, so i am not sure if it is a hardware problem with the screen or a bug resulting from my flashing marathon. Or is this just the normal banding resulting from the windows mobile 65k Color limitation?
The only information about a color banding problem i found was:

My pictures do not look that bad, but this blog post concerns me even more, that this could be a hardware problem.
Thanks
My Nexus 7 (2012 model) display got broken and I've purchased new Full LCD display+Touch Screen Digitizer (from: http://www.aliexpress.com/item/Orig...itizer-for-ASUS-Google-Nexus-7/767556272.html).
Touch screen is working fine, but the display is not working correct.
Problems:
Images is pixelated all the time. Always
Display is not coming properly. Ex: settings screen is supposed to be smooth gray gradient, but coming as color palette (color bars) instead of smooth gradient. (see image 7)
Previous screen is seen next scree. Ex: in settings screen I can see home menu icons (highlighted with red lines)
Sometimes pinkish color is coming, and sometimes whitish tone is coming
I've attached few images I've taken using my Mobile and few screenshots I've taken directly from Nexus 7. In the screenshots you can see the images are pixelated.
Where could be the problem? How does the screen capturing works in Android? I mean as I've taken direct screenshots and those images got pixelated, does that mean problem is with GPU or does Android will capture the image some home from the display?
Can any one tell me how Android screen capture works?
If Android captures what it is sending to display, then the problem is with GPU.
If Android captures the pixels from the display (some how after shown on the screen), then the problem is with LCD.
Can anyone suggest what could be the problem?
(I've attached images as zip file, as direct image upload is lowering the image quality and one may confuse about the actual problem)
Okay, I think I got an answer (or at least part of it).
Answer: Android captures what it is sending to display (technically, from something called FrameBuffer).
So, I think I've problem with GPU connectivity (may be some loose connection?). Can any one confirm?

Hi everyone, just a quick question. When my screen is set to +3 brightness or so I can see that in some menus (for example settings) the colour at the top of the screen is darker than on the bottom!! Please note, you can only see this when the screen is very bright. The more you are looking down on the screen the brighter it gets. When I look at Internet and the backcolour is white it also is darker at the top than on the bottom of the screen.
Is this normal or do I have a defective screen?

Hi,
Few days ago I purchased a new unlocked n910f from a nearby retail store and I noticed something strange with the display.
The issue is - vertical lines are visible if a gray image is displayed. This is visible at brightness levels above 50%.
Same can be seen if a white image is displayed (i.e. a white page in Chrome or in Settings) and the notification tray is pulled down so the visible content of the previous screen becomes dim. This problem is really annoying...
I've created an image with photoshop, 2560x1440 with a #2f2f2f Gray and opened it with Gallery.
The display settings are: Screen mode - Basic, Auto adjust screen tone - OFF, Brightness at 100%.
A screenshot doesn't show any vertical lines...
These are links to full sized images:

2. Photos taken with another camera (same image displayed, different camera exposure)

I've searched for this issue on the web and XDA, found about Mura effect, but nobody pointed out this issue on Note 4 and if this can be fixed. Is this issue present on Your device? Should I request a device replacement?
Thanks,
