I have both a Touch HD (Blackstone) and a HD2 (Leo) with stock ROMs and I noticed that the letters on the home screen of my HD2 are slightly unsharp compared to those on the older Touch HD.
The difference is even visible in screenshots of xda-users who have posted their screens of the two phones (check the corresponding threads on xda).
There, you can compare the sharpness of the letters in for example quicklinks text between the screens of the two phones and you will notice a slight difference where text on HD2 is slightly blurrier that the one on Touch HD. The difference is quite noticable when I hold the two phones next to each other. It is mainly the case with white text on black background throughout the sense tabs where text is blurrier on HD2 than on Touch HD, whereas there is no difference when reading for instance email (black letters on white background) or browsing the web in Opera (colors).
Can someone confirm this difference and explain it? Does it have to do something with HD2 resolution and its big screensize, compared with Touch HD that has the same resolution but on a smaller screen?

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
I'm not sure whether this is a problem with Android (doubt it), HTC Sense in general or the HTC Photos app..
But what I'm finding is that pictures with gradients (usually ones computer generated) have their gradients shown very bady and makes the picture look terrible. Instead of doing a smooth colour transition, it sort of does it in chunks..

As you can see here, isntead of fading smoothly from the red to black, it does those ugly layers. I first noticed it when I had this picture set as the lock screen picture because it does it there too. In bright light its almost impossible to tell, but in the dark it tooks terrible.
Sometimes when I look at the full picture in the Photo app it doesn't do the gradient so badly, but when I go to pinch zoom the slightest it instantly changes to look like that. (isnt just a problem with the one picture btw). I thought it might be something to do with the large picture being resized to fit the screen, but I resized the picture on a computer to be smaller than the screens dimensions and it does the same thing.
Another slight issue I picked up is that black areas in a wallpaper picture don't show as 'true black'. When I view the picture with the black background fullscreen in Photos, the black areas are true black (tested at night - true black of AMOLED screen). But when the picture is set as background, there is a noticeable difference between the blackness of the background and the 'true blackness' of the bottom of the notification bar...
Might be hard to see, but to show what I mean:

Does anyone have any explanation for these problems, and even better, fixes?
I've got HTC Legend unrooted
Cheers
Since the Epic uses SAMOLED and the pixels are self-lit which uses more energy when displaying white, would there be anyway to modify the browser to display white text on a blackground as default?
I was also wondering this, there is an add on in dolphin HD but having a browser that does it would be easier.
Whats the resolution of 5 home screens linked together?
I'd like to know so that I can make some backgrounds for my device, making computer backgrounds is a hobby of mine that I hope to extend to the phone, so to make the background stretch across 5 home screens how big would it have to be?
Thanks
Screen is 480*800, all backgrounds should be 960*800. The number of screens just affects how far one swipe scrolls the bg.
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?
