Hey Friends,
I have noticed something rather strange yesterday on my DHD. When I view content with a black background on my DHD in Landscape mode 3 dots that appear to look like pixel errors show up on the screen. When I tilt the phone back to Vertical mode those red pixels on the black background vanish. So they are obviously not real pixel errors are they? They definitely have the size of a pixel but what I wonder about is the fact that they disappear completely.
What could be causing these artifacts ? I tried undervolting, restarting etc. but they will appear again. In the browser for example they show Up and when I scroll down they vanish for the time I am holding my finger on the screen.
Could someone try running set cpu, switch to landscape and look for those pixels? Any other ideas?
Greets,
Jan
Anyone?

Hi,
Search the Market for "Dead Pixel Test", its a free app that will cycle through LCD colours so you can identify, among other things, dead pixels!
Check to see if you get these same 3 red pixels/dots whilst on the black cycle.

When I chose calendar, i got a black pixel on the calendar bar (gray bar, just under the black start bar)...and when I choose Excel or contact, it's gone...but they are same gray background...
Doesnt make sense...my display passed all colors on PocketLCD ???!!!
and my two "stucked pixel" at Contacts are exatcly the same spot as the ones in the GSMARENA screenshot review...this is weird !!!
Anyone care to explain ? Do u have the same behaviour too?

I can at least confirm this. Same pixels occur on my device. No explanation to this here.

Same here on the contacts screen.
I've got the same, and looking at screenshots on the web, it seems specific to the HD.
ie this diamond shot seems OK:

but HD not:

Yep, got this on my HD too, weird. Perhaps a quirk of the HTC customisations?
i have a dead pixel too when i start my camera. it's strange because the same dead pixel does not appear when doing something else.
i can also confirme the 2 stuck pixels in contacts manager.
strage ....
I'm not going to look for it - if I see it once, it will annoy me every time I look up a contact.
Sounds a curious little feature though.
Yup had this problem once when i installed GSEN had to delete it because it cause my screen to display a dead pixel when their was none. so try uninstalling programs which might be causing it.
Regarding GSen, that is their way of showing the GSen app is running, small white pixel top dead center of the screen. If you soft reset you'll notice its gone until you re-launch GSen again.

Then, we need a new ROM to fix this issue... I wont be bother since it's a SW issue not HW one...
I have the same dots in contacts, doesn't look like dead pixels, otherwise it would have shown on the snowpicture on fullscreen.
its just some lame graphics issues when they made it.. dont worry
I've got the same thing, but it doesn't look like a pixel problem. I hadn't noticed it before, now I can't ignore it anymore

Hi,
i just recognized a blue pixel on the screen when i start the cam .
So i downloaded a tool called "smartUDPixel" to check the screen for dead pixels BUT everything looks fine.
What`s going on? Why`s the blue pixel only shown by using the cam? Any reason for that?
Thx for your feedback.
Stefan
I have one white pixel that shows up in while in camera mode and shooting a dark scene. Strange however as its not visible in any other programs.
Same here too addition to one black pixel dead appears when the screen on blue color :S
If you can capture it, it won't be dead pixel on LCD.
Hi
The pixels as per the original poster is something to do with the WVGA resolution I think as I see the same thing on the Topaz, but not on other devices.

WOW............are you all talking about those tiiiiiiiiiiiiiiiiiiiiiiiny teeeeeeeeeeeeeeny little dots that can barely be seen?
Man my eyes must be **** lol I have them but I had to put my glasses on (there for reading and even then I could barely see them)
Whats the big deal? Flash a new ROM with a different contact UI
And I thought I had OCD lol
Just wondering if anyone else is seeing this same problem. When on a white screen like a Google search or aldiko, where the text is displayed portrait mode to the left and right of where text is displayed there are like faint bleed lines where the text is displayed. I tried with brightness all the way up and for the most part they go away but around 50% brightness if you look closely I can see it. Do any of you see the same thing. Just wondering if the amoled screens are like that the Samsung behold II is like that. But godly enoguh in landscape I don't see it. Just portrait. Just hoping nothing is wrong with my cool new phone.
Here are 2 pix of what I see
http://tauruspc.net/pix/1.jpg

And a better one. Just look to the left and right
http://tauruspc.net/pix/3.jpg
I *JUST* answered your question on google support lol
I have the same thing but mine is definatly not that easy to see.
I just checked and i cant see what youre talkin about so i guess my answer is no
Talk about ironic timing. Weird will look then. And the weird thing is on xda page I don't see in Google support I do. LOL.
Also, I am using Dolphin Browser not default so that may be in play I'm not sure, try downloading it and see if you have the same problem maybe.
Yeh I will do that mainly seems with just black on white portrait mode like Google support. Not xda though.
Wonder if it has to do with power consumption. It takes more power to display white pixels. With the black on the same line maybe those lines with text are consuming less power on the line making the rest of the LEDs on that line of the matrix receive more power, making them brighter?
I tried for about 10 minutes to make that as unconfusing as possible lol
Makes sense. Weird only on portrait not landscape. but just spoke with HTC and they say that haven't heard of any problems like that and can send this in get a problems like that and can send this in get a temp one while they fix it and then switch around again
haven't seen much improvement setting manual brightness either.
I get the same thing, I think it is simply a scaling artifact. When you double tap to zoom the lines are no longer visible.
You can see this effect in the boot loader, but only adjacent (the right of) to where there is text at the left. if you look down where there is no text, and just white space, the ghosting lines across the white are not present.
either way, doesn't really bother me, you really have to look for them to see them.
Yeh double checking I see it there too. So yeh just not me then. Probably just amoled tech. the kind of blinky static lines is what bugs me. Don't happen that often and still kind of have to look to see those but since I have been using heavily since I got it about every 4- 5 hours I see where it gets like static lines horizontally about one pixel think blinky faintly in random spots all over the screen but kindof like static or noise from chip shielding or bad power frequency.
So to make it short. When you install any app with black icon like offitial 9gag app from market try to scroll left and right in app drawer and yo will see black trail behind icon. It also happens in some apps with blaxk background and in galery with zoom in and out. I wonder is it amoled issue or just software. Just try it for your self. And if sombody is on aosp try it too so we know if you have it too.
It's called smearing and it caused by the fact that the pixels are simply turned off when the display need to show black color.
The screen isn't quick enough to "wake" the black pixels so it looks like smearing on the display.
Google ROM doesn't have it, because Google replaced the black with grey, so dark that it almost looks like black. If you set your brightness to full though in a dark room you'll see it's grey. This way your pixels will never be turned off
Me Gusta!
Does it have to do with refresh rate?

Hi- this screen never appeared before and now it does -.- tried wiping factory resetting and this image wont go away from my homescreen. Idk what happened please help looked everywhere of how to remove this but no one has had this issue. This never appeared on stock until after i unlocked my bootloader and installed cm. Tried to use the repair assistant and its still there.
edit: idk why it does not show in my screenshots. here are some photos taken from my iphone... hard to show but there is a white line that is in the background of my homescreen. Shows an sms icon slightly transparent. Annoying **** to look at when I take pics on snapchat. As you can in google playstore and the snapchat photo a SMS icon appears behind the mic in play store and under the switch to facecam icon in snapchat. Does anyone know a fix??
I still have no idea what you are talking about.

lol. ok before on my screen it will be normal fine no graphical errors no visual glitches. pictures wont show it for some reason but if you had my phone in my hand it would show up as SMS icon at the top of my screen like right below the navi bar. Shows up in camera and on my snapchat. Never happened till now. Idk if my screen got messed up or if its the constant switching of roms etc that gave me that glitch. its like a white line that separates the navibar and the rest of the screen at the bottom shows a menu bar on the left corner and some icons. its very transparent under the homescreen display like if the stock rom overlapped
like it shows a small phone screen is under the home screen. in the background- get me?
It's screen burn in. It happens with amoled screens if they are left on a static image too long. You can try some burn in fix tools in the play store. That's why you don't see it in your screen shots it's a hardware problem.

thank you! do you recommend any that would work?
Hello guys,
I was hoping to know if you also have this effect on your oneplus 5's.
The best way to describe is when you are on dark screens like twitter's night mode and you have some images with dark margins.
When you scroll up or down, does it appear a trail that disappears after some miliseconds? Like the screen refreshing itself making that trail disappear.
If you wanna try do this: twitter, night mode, follow for instance Nvidia (his logo is black and dark). Then go to home screen of twitter and try to find a nvidia's twitt. When you find it, look to his logo and go up and down. Do you notice something on the image itself? Like a trail of black pixels or blur effect that disappear after a while?
Hope that you can understand me.
Edit: don't know if I can post links here, if not please tell me that I remove it. This link is from Reddit where it appears an image where you can try this effect:
https://www.reddit.com/r/GalaxyS6/comments/34t923/is_your_screen_defective_test_for_yourself_by/
Edit 2: it appears that the effect is more visible on low screen brightness
Best regards.

Yes, I have noticed it as well though I also had it on my OP3. I think it is more of a thing with OLED screens and low brightness.

Yes, I agree. As this happened on my note 4 as well as my axon 7, oneplus 3 and oneplus 5
Yep, I've experienced that once. Dark purple logo on black screen
It happens on Amoled screens when the backlight is low. I have seen the same thing on all my Samsung phones as well.
I also confirm, low brithness OLED screen (samsung s3, s4, s5, s7, op3, op5)
oled are good for low battery consumption and high contrast ratio (blacks).
Otherwise, lcd pannels will be faster and more accurate with colors.
