Well, unless Samsung can tweak their SAMOLED process/manufacturing then any new displays on their phones are likely to have a similar effect. So if they decide not to bother fixing it, there should be an ever growing market for such an app, despite us being the extreme vocal minority I'm sure.

here link of my video, sorry for crap quality, was filming with nokia 6720, maybe it doesnt show clearly but no more banding for me http://www.mediafire.com/?ijksasdo9i6ba0c
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
You should show them a picture comparison, of course they will never acknowledge the issue. A friend of mine got his screen replaced and says he has absolutely no banding and no clipping its like 32bit on everything but the down side is that the screen is quite dim even at max brightness. So I dont know, gonna see his screen tomorrow.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] indie:
EarlZ, let me know how the screen is and take pictures please. If it is Screen defect then everyone should be chasing to have it replaced. Teach Samsung a lesson trying to fob people off.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Because not everyone will watch movies on the Galaxy Note, 99.99% of the users dont. so its a non issue for them. I dont know what to each but simply take a picture, I showed them a picture of my screen which I already posted here with the iron man clip and a friends phone that does not have any banding/clipping as horrible as mine.

I understand but it affects pictures too. They look terrible if shades of black can't be displayed properly

Someone posted this on the Facebook galaxy note screen issues page

'We have a lot of G-note users in Korea, and as far as I know, almost all users have this issue. Only the severity of the problem varies from device to device.If you knew Korean, you would see lots of complaints in Korean internet cafes. Many of them got replacements but failed to get a good one.

No official response yet from Samsung. Some guess this may be solved by a softwware update.But the recent update didn't make any difference and this issue does't exist on previous AMOLED models. I will have my display panel replaced soon but I am pessimistic about the result.'

The download link in that other thread is broken. Did they pull it for some reason? Also, it looks like it doesn't let you adjust the gamma curve, so is it really a solution or just a band aid like screen adjuster?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
My request for a refund has been approved and I've been asked to wait for 2 weeks for the cheque to clear (same waiting time I had with the Galaxy S2).

They asked me not to have my screen replaced or any changes on the software as they want to examine my unit as is. I hope they can find a solution and I'll just repurchase later on.

It is not normal that a phone cannot displays colours properly. They should clearly mark this info on the box. A phone they mark as HD yet cannot displays colours is shocking and a scam.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
I dont see how that is normal when any other SAMOLED device can display it properly and if they get another Galaxy Note to compare with chances are its gonna have a different type of clipping. Do you have access to another Galaxy Note to compare with ?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EdgaBimbam:
not really. In my country where i live there are places where samsung is advertising galaxy s2,galaxy tab and galaxy note however note always is being shut down.You are able to watch,test s2 and tab and with note u cant. Maybe samsung corporation said not to show off turned on phone cause people could see this defect.

Posted by another user from a local forum, gamma curve is actually great with color information only dropping off at 1 to 0 and its not a sharp drop as well, so a screen lottery can have this issue fixed.

Using the voodoo tuning makes the results worse on his end.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Xindl:
Hi everyone!

I have had my note for about 2 weeks now and I was struggling with all kinds of formats and codecs because of the whole clipping-gamma-wathever issue here. This morning I found this thread and went through reading the whole thing only to learn that it was not exactly the problem, that i thought it was (it's not due to my encoding of the videos i'd like to watch).

I'm still pretty sure that this is a SW-problem. Or to be exact a problem concerning the communication between software and hardware.

I have some videos that give me heaps of pixels and artifacts and then again there is the "lightness and slimness" video from samsung which runs crisp and clear without any of the known problems. I can't wrap my head around that. I mean, it shows clearly that there must be some way to avoid the problem, right? Did no one ever figure out why the hell this video works so well and others are unwatchable? What did they frikkin do with that video??

I love the big screen and I traded in my iPhone 4 for the Gnote because I watch a lot of movies and now... this! I guess I'm gonna wait for the ICS update for this problem to be fixed. If it doesn't get fixed, I'm getting a new phone, although I'd really love to keep it, for the screen is awesome 90% of the time.

Boy, this is really driving me nuts!

Edit: I forgot to mention one experience, that I guess hasn't been mentioned before: I've had a 720p video in WMV. It seems to give me way less artifacts in that format compared to others, though the video had some dark areas as well. Don't know if this info is of any use for someone but anyways...
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
@Xindl

The demo video only uses #000000 for its black color information, no other shades. hence its looks perfect.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Xindl:
I might have accidentally skipped this while reading the thread. Do you know this for a fact, or is it just speculation? And if this is true, why won't there be any clipping on the border from the black background to the coins for example? Don't wanna bother anyone with my questions, I'm just trying to understand this as well as possible.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Fact, but don't take my word for it capture some screen shots and examine it under GIMP's color picker. The coins use an rgb value of more than 16, hence you don't see any clipping. I forgot the exactn value but I think it was 65 or higher. Actaully if you look at the end part with the dangling objects you can see clipping occur on the reflection depending on the screen quality you have.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Xindl:
Yeah, you're right, I could see little clipping in the end, when one of the object turns away from the camera. But that's about it, no clipping on the jellyfish scenes or the coins but that makes perfectly sense, if what you supposed was true.

Still... I need a fix for that....

Did no one at Samsung get the idea that this device could have been intended to watch movies? That's really some bad QC there. I can see though why they would say that no such problem is known, simply because if they'd admitted that, it would be all over the various tech-blogs and would give them some bad credits. Kinda reminds of "there is no such thing as an antenna-gate..."

I really hope that they do know about this and work on it secretly so we will get a fix, or if not a fix, maybe at least a gamma-control-option with one of the upcoming updates. Or maybe someone releases a video player with gamma control options or whatever.

I'm gonna send an email to Samsung now. Let you know, if something useful occurs.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
I honestly don't know why techsites failed to cover this as it happeneds on the nexus as well. Ihave my theories but that's about it.

I've tried to contact gsm arena about this and I never got a response. Even a local web blogger didn't respond. Samsung must have tied their hands about this?

Not just blacks...

I decided to watch a tv show tonight on my Nexus, and I was seeing the "splotchiness" (for lack of a better term) on everything, not just blacks. Would the gamma tweaks address that, too, or just the stuff in blacks?

Also, has anyone had any success with using something like ffmpeg to re-map the color space? E.g. crush all 0-32 to 32 or something so at least blacks are uniform, ala what happens with LCD playback so the artifacts aren't visible?

If his screen can show a correct gamma curve on the gammatest png then he will hardly see any clipping even with the iroman2 clip, but if he cuts off at 3 or 4 then its gonna be the same result as mine or the rest.

His video proves nothing though due to the conditions.

If you get this kind of gamma result on your replaced screen, then you will see minimal black clipping and almost no color banding in movies

But if you get a screen with this kind of gamma result

you will get this kind of output.. more or less...

Every time I see those pics it gets me more and more mad. How the F£*k can Samsung release bull**** like that. We all paid good money for the phone and shouldn't settle for less than anyone else's screen. Mine is similar to the bottom pics.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
And people say we are just nitpicking and its a non-issue, I dont understand how those comparison images are a NON ISSUE.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
The second set of pics are most certainly unacceptable.In fact,I would say that screen is defective and not just a gamma miscalibration as there should not be that huge a difference in shades going from 3 to 4.

The first set of pics is similar to my phone.The gamma calibration is already off in this case as you should not be able to see 1 to 3 and then barely see 4.When I calibrate my notebook to look like my GNote in the gamma test,I need to adjust the gamma number from the stock factory set 1.0 to 1.5.This is the point when I see artifacts occur on my notebook.

When I recalibrate my notebook back to stock factory 1.0 and look at the gamma test,I can't see 1 to 3 and then start to barely see 4 and 5.The artifacts dissapear.

Therefore in my opinion,the GNote gamma is set at 1.5 where it should be 1.0.

The display in Earl's phone looks defective and not just a gamma problem.I would demand my money back.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Does your phone cut off at #4 like mine (2nd image with the gammatest from 21 to 0 ) or like the first one ?

Yes refund is already in process and should be done by next week.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
Mine looks like the first one and even in this case the gamma calibration is incorrect.

The second one looks horrible.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Hmmm odd, thats against all that I've seen. The ones that display upto 4 craps out like mine all of them while the two that ive seen with a better gamma displays like the 2nd image.. clipping is there but I have to look for it, basically its almost perfect. So I guess the gammatest image is not a 100% indicator.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
I think a proper gamma test should show 1 to 3 too black to see and then a very gradual progression in shades from 4 onwards.

In your phone,1 to 3 looks correct but 4 is way too bright.

In my phone,4 onwards looks correct but I should not be able to see 1 to 3.

It probably wouldn't hurt to star this google bug:

http://code.google.com/p/android/issues/detail?id=23862

It's for the Nexus, but it's the same kind of issue. If we can get Google to provide a setting or at least a hook to allow developers to write an app to adjust the gamma, it could make things much better. I'm not sure if the gamma alone will fix it, at least on the Nexus, since I see the "splotchy" stuff in many areas of solid color or which are out of focus in the video even if they're not black.

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] ballfire:
photos were quite hard to capture what i wanted to show. note, s1, s2 all on max brightness. standard display mode. s1 has invisibleshield screen protector, s2, note both no name screen protectors.

first 3 photos from 1.5gb 720p terra nova episode. last from s2e08 lost girl 350mb

note, s1 bot left, s2 bottum right. the blacks on the s2, s1 are much darker.

some might argue it is a gamma problem but i dont think so. (not sure why photo is rotated into portrait when i have rotated into landscape before uploading)

close up of note around that scene

pixellation, blockiness. difficult to capture with camera. worse in real life

note on top, s2 below. pixellation/blockyness left upper corner, right half of image- the hair of the girl, blue top, top right , bottum right. much more so than the s2.

[/IMG]

s1,s2, note

difficult to see pixellation on the right of his head and shirt in the photo but quite obvious in real life.

based on above it is quite hard to tell the differences ,as the images have been downsized, but lined up next to each other the image seems nicer on the s2 than the note. best example here is photo 2.

hmm, starting to look like it may be an issue with your device. ive got that ep of lost girl and terra nova, and i dont see any issues with the blacks. using cheapo screen protector here as well (was a galaxy tab protector i cut to fit).
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] paulshields:
Generally I've found the Note to be extremely good at video. It's only when looking at low bitrate material that I can see blockiness, but that's a problem with the source and/or codec and not the device or screen. One thing I've noticed, which I've mentioned in another thread here about video playback, is that you can see differences in video quality depending on player - e.g. You Tube player can be quite blocky (lots of crunched blacks) with low bitrate sources, while the Browser version through the Flash plugin doesn't show that crunchiness.

On the other hand, Samsung have always been very good with being able to play high bitrate videos (ignoring their Tetra 2 device for a moment...). For example, the oringal 7" Tab could play High Profile encoded video without skipping a beat, and so can the Note. The device definitely doesn't have issues with video quality if the source is good.

Have you changed any of the settings under 'screen mode', in the display section of the settings?

To my eyes it looks like the Note isn't properly coping with the video colour space which is different than the computer colour space (video: 16-235, instead of 0-256). If this is the case it should be fixable in a software update.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] ballfire:
yeah i've tried standard, dynamic, movie mode.. doesnt help

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] qazzi76:
No don't send it back to clove. I have the same issue and so do others. They just dont understand it...

The fact that the video played back correctly when connected to the 55inch plasma is significant.. very significant as it proves that the internal rendering is correct which means this is definitely a screen specific issue that may be resolved with an update.

My eyes like yours are very sensitive to gradients and I noticed the strange gradient rendering when I first got the notr and as such travelled to the carphone warehouse in Oxford st to compare my note but the rendering on the 2 demo units they had there was the same so I know this issue is specific to all notes....
