Ок..

I made some modification in mDNIE profiles for Gnote

Now black level adjusted and no more blocks on video and android interface (unfort. deep black is gone too :( )

Standart profile turning on right after bootlogo appears - ("galaxy note gt-n7000)

It's a small step... but i'm think peoples can make second (i'm stick at this point, can't understend how adjust gamma at overall)

in profile files - mdnie_tune_standard_mode i found gamma settings and change it

Did some1 try this in ICS alpha version??... first i too believed my screen was awesome untill yesterday night i watched a True blood Season 2 Episode 7 video .. start of that episode there were same black bckgrounds which were totally pixelated.. i tried in almost all players.. it was the same... now i played the same video this morning.. i could not see nay of it.. so i think those blocks are visible only in dark places ... those who are saying no issues try it in your night time with no lights on!! and set your brightness to auto, screen mode to dynamic....
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Minor blockiness cant be seen when your viewing a dark movie with all that ambient light and reflections.

This issue is inherit to probably almost all of the Galaxy Notes, but also differ in the severity of the blocking like what my replacement screen is doing.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] indie:
can people start posting there dismay at the screen issue at http://www.facebook.com/SamsungGALAXYNote

I post there about the issue but no one responds. If more and more people start posting about the issue maybe samsung will respond and fix the issue. If we all complain here and not directly at samsung then they may never fix it.

Folow up

Yesterday I saw that a Gnote can have a perfect screen.

So today I went to my Samsung shop to try to find a solution.

So they kindly propose to exchange my Gnote for the second time , but they didnt' allow me to test it in the store , saying that if this didn't do the trick then they will send it to a repair centrum. I also asked them if this was a kown problem or if they already had a lot of return but they did not wanted to answer me.

So the new Note ( 3rd one I repeat )

has all the same defects

, banding in colors and clipping/pixelated blacks in video. But the blacks are slightly better and the banding is worse.

So the problem i even worse because a unique software fix will not do the trick ( depending on how bad is your screen ). It seems to me that the quality control done by Samsung is very poor. never had this kind of experiene with HTC .

I'm gonna take there advice and send it to a repair centrum.

Galaxy note banding / blotchy grey-blacks

Hi Earlz, it seems you are one of the only ones in this thread that has described the problem in precise detail, and after checking the screen of my brothers new Galaxy Note, I see it has the same issues. Banding when displaying color graduations, and blotchy/blocky looking very dark greys in videos that contain shadows or night time scenes. Additionally I noticed the same blotchy issues in photos or pictures that contain shadows etc also.

It seems to me that these screen aren't calibrated properly from Samsung's factories in the first place, like the gamma curve is set far too high for very dark greys/almost black colors.

The other possibility is that the screens have some physical defect in manufacturing that causes them to not be able to display these ultra dark colors properly, in this case I dont think a software solution can fix this problem.

Regarding the color banding, it is possible that ICS with full 24bit color support (dithering for 16bit stuff) might be able to be fix that, but I dont understand why someone on this forum doesn't just load one of the ICS ROMS onto their Note and see if this is actually TRUE or not?

Anyway, now that I feel I understand this issue quite well after having seen it for myself, I seek some advice from you:

I have a Galaxy Note on order myself and still have until tomorrow the possibility to cancel it. Im seriously considering doing this in light of these Galaxy Note display issues with UNKNOWN solutions (if any). What would you do ? Risk getting one with these display issues, or just keep my money and wait til this is officially resolved by Samsung or some very clever developer like SuperCurio?

I appreciate your thoughts.

Thanks in advance.

BTW: SuperCurio's Beta Screen Tuning app barely makes any difference to the very dark color Blotchy issue on my brothers Galaxy Note, so Im not sure this will help many people.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
IMO, If the black clipping is something you cant really live with cancel the order for now and wait for user feedback on supercurio's fix OR wait for samsung to actually fix it.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] kobralabs:
Thanks Earlz, I might end up doing just that. It just seems like a real shame that such a gorgeous high res screen has issues with something as simple as displaying shadows or very dark greys. If I wait a bit longer to see how this all pans out, the Galaxy S3 specs will probably be officially announced, so I can see if thats a better option anyway ( They might have an updated screen of similar size + Quad core CPU).

On a side note, did you end up getting yours replaced by Samsung under warranty? Is the replacement any better in regard to black clipping?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
The strange thing is,occasionally I will come across a youtube video that plays perfect even without using the app screen adjuster.Perhaps it has something to do with video compression as not all videos on youtube are compressed the same.

Here is an example of perfect rendering....

http://www.youtube.com/watch?v=T3tidwW1gGM

In fact,if you watch most of the video trailers by this same uploader,they play fine.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
The replacement screen is not really any better than the first one because I lost the great viewing angles and this one has a far worse black clipping, my wallpapers that were fine now shows black clipping. The only thing that was improved is the lesser visibility on the horizontal lines.. they are now only visible in greys and if you look for them.

Just a pageback the reason why youtube video's dont clip is posted. Only shows that people dont really read :p
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
I did read it but I don't get your point now.Youtube videos do clip but some does not,at least on my GNote.

If there is a software or hardware fault,why do some youtube videos play fine but some clip?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Use a color picker see if those clipped blacks are 0's or 16's

EDIT:

Or could you link me to some so I can investigate.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
I downloaded the rusty nail video direct from the link supercurio posted and there is some clipping on some parts of the video played back on my GNote.

The fact is though,that same clipping is also present played back on my notebook, albeit not as pronounced probably because the black level is so much deeper on the GNote.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Its been established that it clips on all Gnotes and those who say they dont have clipping are yet to prove it, i would classify the clipping on rusty nails as already massive..

On other devices though that uses SAMOLED (aside from the Nexus ) it does not clip, SGS1,SGS2,Samsung Wave,Samsung Wave3, Moto Razr.. ect ect
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
Earl,I see the same clipping on the display of my notebook.How do you explain that?

My notebook has a backlit lcd display.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
I honestly dont care about the clipping on your netbook, this is a Galaxy Note thread :)

The same video does not have any clipping on my cheap 22" TN monitor so yeah..

Actually the video has some greyish artifacts on its black background the gamma profile on the Galaxy Note/Nexus is making it more visible than it should be, thus producing this clipping that we see.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
Well you should care because the point is that it could be the source and not the phone if it happens on my notebook as well.

Other phones may not be good enough to see the clipping.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
If you are seeing the exact same clipping per frame on your laptop as compared to the Galaxy Note then they share the same common issue, incorrect gamma levels.

Previous generation SuperAMOLED devices dont show any clipping at all, the black clipping you see on that video is supposed to a very smooth transition from grey to black and vice versa.

My cheap TN monitor does not show any clipping, the Samsung series 8 LED-TV we have at home has no clipping either but these screens are 'not good' enough I guess.

The source files uses a mixed #000000 and #010101 for its black background and with the incorrect gamma on the Galaxy Note these #010101 light up too much.

load up the image bellow on your Galaxy Note using the stock gallery,web browser app and also load it up on your netbook.

The one good thing about this gamma setting though is that you actually see a lot more details in darker scenes that dont hit the black clipping point.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
Ok,I have loaded it.What am i supposed to be looking for?

---------- Post added at 05:48 PM ---------- Previous post was at 05:39 PM ----------

Perhaps my notebook is faulty as well.I definitely see the clipping especially around the 2.25 to 2.30 mark in the moderat video.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
If you cant find anything wrong with that image on your Galaxy Note then Im surprised you can even notice the clipping on vids. No offense intended. Just saying.

Those numbers represent actual RGB values and was originally posted by DaveC1964, on the Galaxy Note gallery you can see a complete cutoff from 4 going to 3 which is what is causing the clipping, on the web browser the cut of happens at 2 going to 1 which is still also causing black clipping.

The transition per value should be very smooth, to avoid any clipping.. even 21 on the Galaxy note is way to bright!

Your notebook maybe faulty or just using a different gamma profile to make things appear brighter than they are.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
The graduation from black to grey is definitely not as smooth or as great on the GNote compared to my notebook.

If it is just a gamma curve calibration,it shouldn't be a difficult fix for Samsung.

---------- Post added at 06:06 PM ---------- Previous post was at 06:02 PM ----------

On the plus side,the black background on the GNote playing that video is pitch black.I don't think any high end plasma or LED tv is going to come close to that.

If the clipping can be fixed,it is going to be a superb display.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Theres a big "if" they want to fix it, you should see the same video on the Galaxy S1 or S2, even with a 4" screen that video looks superb!

Galaxy Nexus also suffers the same issue.

Why does this software issue have such great differences on different galaxy notes.

Mine on the left, a friend's Galaxy note on the right. If you guys wanna contribute your photo get the same scenes from this link

both devices purchased on the same shop but at different dates, both in KL7. The demo units on the store also showed a different kind of black clipping.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] BerreZ:
Update

Still waiting to find the perfect Gnote I went today on a quest.

First I went to the shop where my friend did buy his Gnote with a perfect screen , there pretend to buy one if I could look at the screen first . I've learned now that you can easily see the banding in the calculator ad until now when you have banding you will have clipping. So there I've tested 2 phones , both had the screen issues. Then thsi afternoon went to another shop could look at one they had in display this one was the worst I've seen.

So as from today I had 3 different Gnotes , could look at 3 models in a shop all with defaults and have seen 2 models with what it seems a good screen.

So it's not looking very good for the moment with a only 25% of perfect phones.It looks more like a lottery.

Friday I'm gonna try the same approach in some other stores .

All the Gnote with the issues where not equaly bad.

I also mailed samsung Europe more than one month ago a claim.

They seem to have finished to sleep because I've got this response today , but I'm still trying to understand what they are saying ;

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] kebong:
unless it's gamma issue, it's the bitrate of the video file that's causing this, not the screen itself.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
Looking at those pics it seems my phone is not as bad.

If the gamma setting varies dramatically from phone to phone,I don't see how Samsung can come up with a generic software solution.

OMG I just found something. If I play the file in standard mode the screen is just like EarlZ. However, If I play the file in Movie mode there is a huge improvement, almost night and day. It's not 100% like it should but it is definately watchable. EarlZ try the same.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
It would not hurt anyone if you just downloaded the video, its not a bit rate issue and its something you can confirm, play it back on your galaxy note and check if you have the same issue. Post pictures if you have or dont have.

Pictures please if possible.

Its pretty hard to pin down right now since it is a difference per screen, if its a software issue then all phones must have the very same results but yet I see a phone not affected by this. It could also be the stored calibration profile that is with in the screen it self but it beats the whole point of calibration if they store random gamma profiles per screen.

Because people started to accept defects as 'normal' with the previous SAMOLED devices so samsung now thinks they can get away with it and just blame it on manufacturing. If customers what a better quality control then they must do their part as well.

Much better if they have pictures to back up their claims.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] indie:
As my post above states there is a huge difference between the screen modes. In Movie mode the result is much much better. When comparing images or screen shots I think all test pictures should be set in standard mode. I'm sure all notes will be showing poor shades like EarlZ's pictures. However in Movie mode it is almost gone.

EarlZ your second picture from your friends phone looks like he was set in movie mode, hence why yours look so poor in comparison.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] SAlmighty:
Ummm....

Do you think the extent of blockiness varies depending on Firmware, since there are different firmware for different regions? Just wondering...:confused:
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] indie:
Hi

I personally think it's to do with the screen mode now. I cannot be that all notes are pre-configured differently. Some people have set it to different modes and there will be differences in images as I have found out today !

I forgot to add that there will certainly be faulty screens as with any piece of hardware
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Settings are identical, standard mode, brightness at 15%, auto power saving disabled. KL7 firmware (SAME PDA/MODEM/CSC). But before this picture was taken I asked my friend to view the iron man clip on her galaxy note and she said it looks like on her S2 but only brighter (more details seen) with extremely minimal black clipping. I didnt take her word for it so we decided to meet up and I was amazed by what I saw.. color banding was less severe on her galaxy note, none to be seen on the calculator and lesser extent on the skype,angry birds and XDA app but what surprised me more is that the black clipping on her galaxy note is extremely minimal it only clips mostly on the edges of the video where is supposed to be #000000, we did this test in a semi-dark room as to eliminate any possibilities of the reflection giving skewed perception.

In movie mode mine shows no difference what so ever, also I noticed that when ever fade out effects are done on my screen ( Multi-picture livewallpaper ) it doesnt fade out properly into total black but shows a very rough transition like some colors are left over, on her screen its very smooth fade in fade out.

I would also notice movie mode right away as the yellow tint it adds to the screen is just horrible.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] indie:
How do I take a picture of the playing file? Normal screenshot shows just the player and not the file. I'm using the stock video player btw

---------- Post added at 11:22 AM ---------- Previous post was at 11:17 AM ----------

I can also confirm when in movie mode the banding is barely visible on calculator. On standard it definately visible. On my note if I keep it in movie mode banding is almost gone. It seems the mode does some sort of trick to hide the banding and clipping.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
This might not be the most accurate explanation but from what I can see with movie mode it limits the range of colors to RGB16 and only goes to RGB0 when the color information is actually 0, RGB1 is bumped up to RGB16 if you noticed movie mode is like playing in youtube web browser blacks are more lit and dark scenes have a greyish overcast.

We used a camera to capture these images, with a 2 second shutter speed, it just so happened with have the same camera as well.
