[Touch HD General] Raziel1:
again as i said. thats pretty normal. the reason you only see this on top bars of some application windows is becuse those window bars are made of very thin gray/black lines which are close to each other.
[Touch HD General] evilskanker:
Well,when I open the 'System Status' screen (by tapping one of the icons in the taskbar), the whole screen seems to flicker (if brightness is high). No idea what to do. May report it to Orange and see what they say.
[Touch HD General] Raziel1:
as far as i have seen, it also concists of small grey lines. but try it out and take a picture of your pc monitor. try do get a sharp one and then view it on you HD device. you should notice the same flickering
[Touch HD General] asci:
This is the question: if we had two HD side by side on 'System Status' screen and they both had the same behaviour, well that kind of "flickering" would be normal. But if one of them has that strange visual effect and the other one has not it, well the first one must be returned to seller.

WHO CAN MAKE THIS TEST ???...before I decide to return it?
[Touch HD General] asci:
I just got in touch with TIM Customer Service and I asked for the replacement of my Device...
[Touch HD General] atomikpt:
you think its not normal then?

was the other devices with same issue or you didn't tested it yet?

well I think its a minor thing, that you can live with, but for a perfectionist, its hard to live with ;)
[Touch HD General] asci:
I didn't test yet, becouse I didn't find another people with HD in my city to compare. Well, I'm a perfectionist...and thus TIM gives me the possibility to replace it I will...
[Touch HD General] evilskanker:
Any further news on this yet? Orange have agreed to replace my handset too which is nice at least.
[Touch HD General] miland:
I have exactly same problem. The top bar is flickering. I guess all devices has this problem.

HW reset is not a solution.

Ideas how to stifle:

1) change the top bar

2) fade out the backlite (using sensor or manually)

3) maybe newer ROM in the future
[Touch HD General] evilskanker:
I have had my device replaced and can confirm that I do not have any flickering on my new device. Being one of the few people to see both a flickering one and a non-flickering one, I can confirm that it seems some devices have a fault in them. There should be no flickering. It would be good if asci could also confirm. Sorry if that is bad new for any of you!
[Touch HD General] asci:
I will when it will be replaced. Your request was satisfied very quickly, I hope to get mine as well the next week.
[Touch HD General] Timbojames:
I also have the flickering screen and I'm considering an RMA.

Also when I look very closely at the top bar some parts look a bit purple, anyone else has this? Then again I have the feeling that there wasn't any flickering the first few days i received it, quite strange.
[Touch HD General] sectorlord:
Did you guys tried to turn off the light auto sensor...

How about comparing the flickering unit's ROM version to non-flickering one ?
[Touch HD General] asci:
I said it from the first post: the light auto sensor is turned off.

Evilskanker just copared it...
[Touch HD General] mrpetrov:
Got my HD today. When I go to Systems Settings by tapping the top row of icons, I do

not

see any flickering either at the top of the Systems Settings page or elsewhere on the page.

Just another data point.

Petrov.
[Touch HD General] Timbojames:
Well that page is flickering at my device, as well as the screen when I change the volume and the top bar at the home screen where my provider is.

Btw, my rom version is: 1.14.404.3 (22273) NLD
[Touch HD General] ez2remember:
Sounds like a bad manufacturing batch. Get a replacement...
[Touch HD General] mrpetrov:
Famous last words! Today (I only received it yesterday), I can notice the flickering in the screens you mention, when yesterday I could not! I can see it most clearly in the volume screen, but you can see it at the top if you look really carefully.

I have not installed any programs. I only noticed it when I took off the original screen covering (the one with the writing on it) and replaced it with the blank screen protector suplied by HTC in the box - only after this did I notice it!

I wonder if that has anything to do with it...?

I'm running ROM version 1.14.405.3 (22273) WWE

Radio: 1.09.25.14

Petrov.
[Touch HD General] lazyboy:
I noticed the flickering on my HD after I'd had it a few days. Then I needed another for development so a ordered another one and was delighted when I compared the two devices side by side and saw the new one wasn't flickering. However, after a few days the new one is flickering as well... So, it looks like it takes a few days... I have no explanation for this!
[Touch HD General] solod:
I noticed flickering with one program....a video tune up cab from xda dev...and stopped when I removed it.
[Touch HD General] sectorlord:
Looks like video driver problem or 3rd party SW messing up ...
[Touch HD General] mrpetrov:
I'm not sure it's abnormal - I think the people noticing it (like me) are probably just perfectionists (or another less nice term starting with "an..".:)).

If you have a look at the large high res picture of the HD on the Blackstone wiki ( http://wiki.xda-developers.com/index.php?pagename=HTC_Blackstone ), then the same area bar (where the "Weather" title is) also flickers on my new

laptop

if I look closely and carefully. I think it's just a product of having the lines so close together.

[Touch HD General] dz@:
Flickering

I experienced similar flickering on HTC Diamond. It appeared occasionally and was most noticeable at a screen with thin grey lines (like default home screen). It lasted through different ROM versions I applied.

They say that SPL is the cause of flickering.

So if it is same issue for HD you should wait for new corrected SPL version.

You may search Diamond part of the forum for more info.
[Touch HD General] mrpetrov:
Pardon my ignorance - what's SPL?

Petrov.
[Touch HD General] sectorlord:
So, is this a SW (SPL) issue ? a bad batch ? or HW ?

How to make sure I could order the good one ?
[Touch HD General] SomethingWicked:
I disagree as well. An LCD screen shouldn't flicker, unless it's specifically being told to (for an effect), or it, or it's controller/digitizer, is defective. Call the place you purchased it from and see if they'll exchange it for you. Otherwise, you may have to deal with HTC Warranty... :(
[Touch HD General] mrpetrov:
The whole screen doesn't flicker - it's only when there are black and white lines extremely close together (that make them look grey) that the particular part of the image "flickers" - at least for me. And it's only noticeable if you get up close to it or if the lines cover the whole screen.

Petrov.
[Touch HD General] dsm52:
Try this test...

This is how to see the flickering on your device - try this test indoors.

1. Set your device backlight to brightest (Start, Settings, System, Power, Backlight. Disable auto adjust backlight and set to Bright. Select OK)

2. Hold the HD about 10 inches (25cms) from your eyes

3. Press the volume up/down button and stare at the centre of the screen.

I can clearly see flickering in the gray areas of the screen, as though it's an interlaced picture.

Anyone NOT seeing this at all?

ps. Don't forget to reset your backlight settings back to what they were, or the battery will drain quicker with these settings!
[Touch HD General] kamilyo:
I also notice this flickering of the screen but it's not very disturbing and noticable only in dark. I think this is just the way this device is made. I say this because I saw other touch hd's with exactly same flickering problem.
[Touch HD General] asci:
But many others don't have it...
[Touch HD General] sumitescp:
Hi people. I just got my blackstone today. I see this flickering at the moment because it is night. In the day time i could not see any type of flickering.

This happened to my diamond with the MFG HARD SPL which is 1.40.

It could be related to SPL. We will only see if it fixes after new HARD SPL comes out and/or other newer spl.

This might be happening coz of rom/drivers. Again after HARD SPL comes out we will be able to test new roms.

I am not bothered about it as I am half blind:p(jkin)

BTW i have the UK version check for rom details on my signature.
[Touch HD General] sectorlord:
I think it's SW or driver issue.... since only on interlaced black and white lines its happen!!!

Everyone agree ? so what SPL ?
[Touch HD General] ez2remember:
Tried this and still see no flicker on mine.
[Touch HD General] sectorlord:
some people just dont look harder enough....

most of them can live with this flickering...
[Touch HD General] stepw:
It may have something to do with it, Petrov...

I doubt it;s a ROM or SPL issue. Chances are this effect is caused by a combination of optical parameters of the LCD matrix, digitizer and screen protector. High density LCDs used in latest devices in conjunction with low grade screen protectors are prone to light waves interference problem, see http://en.wikipedia.org/wiki/Interference

There's a command available in HD SPL to show LCD type:

display 2

So, my HTC HD with SHARP LCD and stock protector is flickering on grey backgrounds.

Someone with a screen that doesn't flicker, please post your

1. LCD type?

2. screen protector used?

3. stock screen protector?
[Touch HD General] asci:
That's a good idea...but if someone who has flickering with stock screen protector on, could remove it to verify if effect persist...would be usefull as well.

I didn't understand how to check my display brend...
[Touch HD General] stepw:
asci,

search the forum for mtty, start you HD in bootloader mode (press and hold "volume down" button while turning it on). Disable USB connections in ActiveSync, start mtty and connect to USB port to access SPL command prompt.

Type

display 2

and hit enter, it will output your LCD panel type.
[Touch HD General] sumitescp:
SO what does actually this do?
[Touch HD General] mrpetrov:
I would, but it took me too long to get the original protector on and I don't have a replacement protector...:) Sorry!

Petrov.
[Touch HD General] st3ch0r:
ive seen 4 different devices, all flickering in the same way.

(offtopic but maybe also interesting: ) all 3 phnes had exactly one tiny ding in the black frame of the screen in different locations. those were not easily seen, but if lamp light got reflected directly by the black frame of the screen, one could observe some kind of irregularity at one spot. the screen surface was not affected itself, but it seems like the black foil under the surface has these bumps quite often.

all in all i am not really impressed by the quality of the device. the production process seeems to be quite crappy and the materials used are not really top notch (which they definitely should be, given the price.) i will keep the phone because there is nothing really comparable on the market right now, but i will be reconsidering it more than 1 time before i will decide to buy another htc phone when it comes to it in 1 or 2 years.

edit:

if i check http://www.htc.com/www/product/touchhd/overview.html with my thinkpad t61 or x61s and look at the gray background, i also see that flickering on the screen. could someone give me a quick hint on how to replace the upper and lower menu bars backgrounds specifically?

edit2:

it also flickers after removing the screen protector. (apropos screen protector: cant believe that invisible shield is available for the new blackberry already but not for the htc.)
[Touch HD General] stepw:

[Touch HD General] Imperium:
It's not fairly uncommon for a LCD screen to flicker due to some colour mixture..

I've got it on some websites with my reguar 24" Samsung LCD screen.. (for example: www.tweakers.net, the 2 sidebars in some articles will flicker as well (lightly)

And since i flashed this "Manilla 2D" on my TyTN2 i've got the same issue, sometimes it flickers, sometime it does not. So i reckon the problem is software related instead of a hardware issue.
[Touch HD General] sectorlord:
dont think this is a HW problem.. it really depends how HARD you stare at your screen... The gray threshold between white and black it not on the midpoint (marginal white or black) that's why the driver switches between the two..thus the flickering..!!

It's SW issue...
[Touch HD General] asci:
Uhm...just confused now. I still couldn't have it replaced by TIM carrier, now they told me (after almost 1 month!) they couldn't replace it by themself, but they have to return it to HTC, I have to wait 20 days untill HTC send a new one to TIM, than I can have it replaced. It's simply scandalous!!! But that's the way TIM use to care their costumers.

So I decided to cancel my purchease so that I should send my HD back to TIM and they will refund my money (and it will takes at least 20 days!!!)

But... it is not an HW issue but a SW issue, than I could take it without returning it back to TIM...

Who can advice me???

P.S.

ADVICE TO ITALIAN PEOPLE:

NEVER NEVER NEVER BUY TO WWW.TIM.IT SHOP BECAUSE CUSTOMER CARE DOESN'T EXIST!!!!
[Touch HD General] tsungha:
Flickering is down to software

Hey all,

Right I have been reading this post for a while now.. The flickering will all be SW related and not down to the hardware. Its all got to do with the resolution and how the lines are set within the grey area. So people thinking that it is down to HW.. don't worry its not. I am 95% sure that it is sw.. and I will post something soon to prove this point! I am at work right now so I cant do that yet.. but it is SW related!
[Touch HD General] snoediewoets:
Flickering on the grey-lined bar on top of the Touchflow 3D

I have looked at this 'issue' too and my Touch HD has the same slight flickering. Its due to a rastering in the colours and the lines that causes a slight inteferance with the screen raster of the LCD (lines). The image is interlaced presented and not in progressive scan. So the picture is made up out of odd and even lines that are showen one at a time (first odd and next even lines switched back and forward).

I think that this 'hardware - limited' projection can not be fixed by software. HTC should change the colour to a normal (unrasterized) colour.

greetz,

Marc
[Touch HD General] asci:
Your opinion is very interesting, and it points to an hardware problem. But How could it be that some device has this problem while some others don't have it? Some devices have this hardware projection limits and some others don't?
[Touch HD General] fasty:
Perception of flicker varies greatly from person to person, so perhaps even if the hardware is all the same, some people notice it whereas others do not ?

As an example, I am very sensitive to flicker on conventional CRT screens. I can even distinguish between refresh rates of 60Hz, 75Hz and 85Hz and would find anything less than 85Hz unbearable, while some colleagues cannot tell the difference.

Another possibility: The response speed of LCDs varies with temperature. Are the people noticing flicker using their PDA in particularly warm of cold environments ?

- Steve
[Touch HD General] asci:
Yes...probably I am very sensitive to flickering...

I noticed it increased after some minutes of usage...so it increased with warmer status.
[Touch HD General] fasty:
Odd thing is, I have not noticed any flicker on my HD even though I generally tend to be sensitive to it...

Perhaps the LCD is slow because it is cold weather here in the UK at the moment... :p
[Touch HD General] CEPi:
I just changed the Wallpaper to a lighter green one on today screen, and can't see any flickering...so yes flickering is visible on default black/gray stripes.

Sure i can still see flickering a little through other default wallpaper tabs.
[Touch HD General] sectorlord:
I have check the display HD here in HK...they dont flickers whatever I looked hard...

But I can see some slight gray shadows on the most bottoms (caused by backlights) when the diaply is all white (eg systems-screen alignemnet...)

My eyes are sensitive to this..but not the flickering...could it be like people can here 20Khz sound others not ?
[Touch HD General] Iceman77:
i did some research of my own, held 4 touch HD phones in my hands today, all with the exact same problem. so it is not a single defective phone if it is a defect, it might be a production error or a software problem.

also made a call with HTC Netherlands. the person on the phone also had an touch HD and spotted the same problem. he told me this was a new problem and he could only send it to HTC hoping that more people will report on the same problem and that they will start working on it.

he thought it had to do with the refress rate of the screen. i don't whink it is, as it only has this problem with certain teints of grey. (like in the touch flow interface)
[Touch HD General] sectorlord:
Have anyone with this problem..reflashed their ROM with a new one (or at least with same version with units that's NO flickering) ?
[Touch HD General] lukexda:
I've had my new Touch HD for a few days now.

It didn't take me long to notice the horizontal bars flickering on the title bar. If I pay attention to it it drives me nuts. but if I don't pay attention I mostly don't notice.

I assumed it was either a perfectly normal artifact for some LCD, or something perfectly normal for the way our eyes work. I've seen it every now and again on my LCD PC monitor at certain web sites. I always assume that it is just bad art design and I assume the same this time.

Sometimes I can see it and sometimes I cant depending on the light... the angle of the screen and how close I put the phone to my eyes.

I want to just replace that graphic with something that doesn't flicker. I thought it would be an easy solution. However, after searching through all the many images in the windows directory on the devince, I couldnt' find one that looked like the horizontal lines that are causing the flicker... too bad. Maybe somebody else might have better luck
[Touch HD General] holzbaer:
Hi,

I can tell that there are different configurations that a LCD-controller is being programmed as I am a hardware developer for embedded Systems. The most important thing is the timing of the Hsync and Vsync -Signals which should meet the specifications of the Display manufacturer.

I have noticed different flickerings when these settings are not quite good.

Maybe it is a problem which could be solved due to a Firmware change...

But I observed the problem a few days after I got my device, so it could be a thermal problem too.

The only ting we can do is to wait for a feedback of htc engineers, and maybe a new firmware version!
[Touch HD General] mrpetrov:
To remove the flickering curtains on your screen, I installed this cab, attached in another thread:

Now the only flickering I see is when I change to the ring volume screen.

GOOD SOLUTION!

THANK YOU!
[Touch HD General] obender:
Everybody has it, not everyone admits it though :)

No seriously, it's there for all HDs.
[Touch HD General] asci:
Well, in few days I will verify it by myself. But other people who get it replaced, could verified that the new ones don't flicker...or they all are liers?
[Touch HD General] obender:
If you read all posts then you would notice that some who had those HDs replaced "started" seeing the issue after a few days.

My take on this, it is always there. It's a placebo effect for those who just got the replacement. Some are kind enough to mention it here, some are... well maybe just upset that they went through all these troubles for nothing.

Also in many posts here you can see that people describe the same effect seen on their laptops. In my opinion this not a defect it's just the way it works.
[Touch HD General] monte0815:
well, i also replaced my hd through amazon 2 days ago... really the flickering is still there... best to see in the system overview after clicking in title bar...

not sure what the nocurtails.cab do - but it's still there....

maybe its a failure and maybe we should wait till replacement 6month...

[Touch HD General] asci:
Yes that's all...but what is incredible is that if you open System State page by clicking on battery on the top bar, you will find another flickering page becouse of the texture of background. So what I would like to ask to all that geniuses is: was to change also this background too difficult for all you HTC developers?

:mad:

This is just a TouchFlo issue 'cause if you don't use it, and have a grey background (like the volume one) there are no flickerin.... So maybe a new version of TouchFlo needs to be released soon...

weldone htc solved flicker issue by painting black over the grey bar so you don't see anymore, really hd has disapponited me ,it shouldn't be more than USD500 its not a well built device ,looks like they made in hurry ,i bought 2 of hds one for ma bro and one for myself,we both have dead pixels on the screen,graphics arent really so called HD and i noticed one of my hd is bit loose in the bottom part plastic around usb doesn't feel so firm.

dfinately doesn't beat iphone's graphics or touch,thats for sure, anyways

we got rid off/hidden that flicker for now :)
