Hi Everybody,
I got the HTC Desire HD from a time, just i am asking about something
There is a matrix of dots which is visible under the screen in certain light conditions (when the Screen is off), I know this is the Multitouch Matrix and this is normal
but i have other Grid of Dots on the surface of the screen itself, you can see it when you illuminate the screen and there is a white background for example or any solid color, is this considered normal
what is this other Matrix
Note : this one appears on the surface of the Glass of the Screen, I also noticed it on HTC HD7 but it was very strong than the Desire HD Case
What is this Matrix
Thanks
If I'm honest I think it's the exact same matrix of dots...
If I close either my left or right eye, I can't see it any more, but when they're both open I can see it, though it flickers between alternate dots.
If I then tilt the screen then some appear and some disappear. i think it's just the white background playing tricks with the eyes. They appear red to me also...
I think it's the same one, just looking a bit weird because of the backlight...
There are two layers/arrangements of dots. A grid of dots about 1mm apart and a grid of dots about 5mm apart.
you should see the matrix/diagonal lines on the screen of the Archos 101! very visible at any angle when screen is off

I noticed on my diamond..that if I don a white display, I see some gray triangular shadows on some side... it is caused by the backight not perfectly distributed...
And I could see the light margin inside those four sides...
Some screen (like Samsung Pdas) is just perfect...
Is HD having this imperfection as well?
Hi,
I wonder if anyone else has noticed this in the blackstone; I can see a grid of dots all over the screen when it's turned on. Ok, you have to look closely, but it's a bit annoying. I can see the dots better when I have a white or green background. For example, going to Start -> Programs I see the dots in the space between the icons.
I know the dots are from the 'resistive' layer, the dots are the sensors of the touchscreen... but they become visible and appear as small green dots perfectly aligned. I don't see them all the time, only when I have a white background or looking with a certain angle.
Should I be concerned? Could it be a problem with my screen?
Thanks!
Sounds a bit strange to me, the only time I can see the dots/grid is in bright sunlight. Then they look like small pin points in plastic.
i've never noticed that on mine...
That is normal, those are touch sensors for the screen. They allow the screen to recognise a touch.

Agree, but I had other PDAs before and never seen the dots when the screen is turned on. I don't care about the dots being visible when I'm under a bright light; my point is that I can see the dots when the screen is turned on, no matter under what kind of light. When I have a white backround, it looks like there's dust on the screen. If I look closely, I can see the dots in green colour, as a result of the reflectied light from the screen. I know they are the touch sensors, but it seems no one else can see them--
Any idea?
Thanks!
it is indeed normal especially under bright sunlight. However if you insist that you can see them when you switvh your device on, no matter the external light conditions, there might be something wrong with the screen. Have you seen other HD phones recently? Do you see the same dots there when they're switched on?

I haven't had the chance to see another HD; I've looked at a Diamond and Cruise, the dots are NOT there. I've tried to take a picture, but seems impossible to see the points in a picture (at least for the N95's camera).
I found an old tread talking about old PDAs that had the same issue, maybe they explain the issue better: http://forum.brighthand.com/showthread.php?t=207321
I'm not sure if I should send the HD to the service. Anyone knows how the 'worlwide warranty' works? I sent an email using htc.com site, but they don't respond.
Thanks!
Any advice on this matter...?
I don't know about colored dots, but every pocket pc I've ever owned had the dot grid visible in sunlight, it is normal, they should be clear dots though.
Hello everyone.

Are someone has same issue? and how to fix it? thank you very much.

The best I could to to check mine was to open up my email. The whole screen is white. I did not see anything except white along the edge.

thank you very much.
please try in LCD Test(*#0*# in Diagnostic Mode) select RED you will see a white border but on my device left-border is green (other sides are OK).
It's very hard to be absolutely sure on red, but on blue and green the edges are definitely all white.

I loaded your JPG onto my Focus and the left side is green. The left side is always green, but the right side and even the top and bottom can also appear green if you hold the phone at certain angles. The green can also appear purple at extreme angles.
Is this a manufacturing flaw, or just a characteristic of AMOLED screens? Could it be some sort of back-lighting source that's located along the left edge that's causing the green tint?
I loaded the picture after downloading it and then attaching it to an email.
It does have a strange tint on the left side.
I then created my own version of the image. I started with a 480 x 800 blank image in Photoshop. I filled the entire image with black at 100% opaque.
Then I stroked the outer edge with 1 pixel of white. I repeated this using 2 pixels and then 3 pixels. As you can see, it is still visible at 3 pixels, but it is starting to turn white. I think we are seeing a consistent result that means the AMOLED screens have a slight design problem that is not considered to be worth holding back this technology from the market. I know I like the display and this is minor.
Sometimes I see it less, sometimes more, it's most noticable on dark backgrounds, BlackPlayer for example. It looks like colors are washed out but not the whole screen just around the edges of left, right and upper corner. I tried taking a picture of it but it doesn't show so I had to draw it to give a clue on how it looks like. It's pretty accurate. Could the screen be failing or is it an issue with connectors or something?

My xa2(h4133) turns off the light at night and looks at the black picture,the brightness is the highest,it can clearly see four color pixels: white,red and green,one in the upper left corner and two in the lower right corner of the screen,my version number is 50.2.A.0.352,I tried to take pictures,it was too small to capture,do you have any of them,please?
By the way, look at the black picture. Is there light on both sides of the screen?
RMA, I also had some (much more) dead pixels. They replaced the screen, now everything is perfectly OK.
