Yeah, we know, i was just interested on how two screenshots of the xda startup screen look different, they should not.

John.
[Galaxy Note GT-N7000 General] jkc120:
AFAIK, the screen in the SGS III is the same as the Note/Nexus. Same new HD Samoled (NON +) screen. So it will likely have the same blocking/gamma/crush issues.
[Galaxy Note GT-N7000 General] npras42:
Not necessarily or 2 reasons:

1) The screen technology may be the same but that does not mean the screens are the same. Samsung have already showed off the fact that the red subpixel is smaller than that on the Nexus in the SGS3 screen.

2) Most of us agree that a lot of the screen issues are down to software setup problems rather than the actual screen technology. Samsung may have put more effort in to setting up the screen better for the SGS3.

Not saying you are wrong. It may have exactly the same problems but it may not as well.
[Galaxy Note GT-N7000 General] jkc120:
Good points. Sorry, just bummed that I am basically never going to be able to watch a video on my Nexus without cringing! hahah
[Galaxy Note GT-N7000 General] yiannisthegreek:
I too don't think this is the case as my GNex did not have this black crush issue and the screen was similar / the same.

I have also noticed that on my note the only videos this black crush happens to is on YouTube. When I watch a flash video on the browser it is clear as a bell but on YouTube it is block and blotchy.

Also the Samsung Note introduction / advertisement video that came with my device plays in the native video player clear as a bell as well.

Could the issue actually be with YouTube app or perhaps a combo between the Note and how it processes video from YouTube?
[Galaxy Note GT-N7000 General] jkc120:
I don't know what you want to call it, but videos (even 1080p 12Mbps bitrate) look like ****e. Blacks have color banding (like a thick gradient) and even normal "solid" colors show this effect and blockiness. I understand the blockiness is largely due to compression artifacts, but they're hardly visible on LCD but really prominent on the Nexus screen (and the Note, I'd imagine). I guess it's just a limitation of the screen tech. :(
[Galaxy Note GT-N7000 General] shaolin95:
On my Note running GB it looks like that with the banding. I tested on my Galaxy S (Captivate) and it looked perfect.
[Galaxy Note GT-N7000 General] noteworthy:
I have tried all of the video players available on the app market and I have found 3 players that improve black rendering over the standard Samsung player.Kascend video,Moliplayer and Movie Player Vista.

These players don't fix the issue completely but they can make otherwise unwatchable videos at least bearable.On videos where the black clipping is not too severe,they can play them perfectly,at least on my Note.Black clipping seems to vary from video to video.

Try them and tell me what you think.
[Galaxy Note GT-N7000 General] PaulF8080:
I get all that and that is why I was surprised that a screen shot showed banding. I am guessing that some banding is totally different from black crush.
[Galaxy Note GT-N7000 General] PaulF8080:
Let's say the XDA app's flash image is smaller than the Note's screen. To enlarge the image to fit, they spread out the image's pixels. Could the algorithm that fills in the gaps between the spread out pixels cause banding? Is the unique size of the Note's screen the reason for the banding?
[Galaxy Note GT-N7000 General] paleh0rse:
it is. ;)
[Galaxy Note GT-N7000 General] truelies1:
4.0.3 also improved this problem.
[Galaxy Note GT-N7000 General] generator_g1:
Updated my Note to ICS a couple of days ago, the banding in the XDA app has been significantly improved since GB. Also the banding on the Angry Birds Rio screen is gone already.
[Galaxy Note GT-N7000 General] noteworthy:
There is also an app called Toys Player.It has a gamma adjustment and it's free.Adjusting the gamma almost completely eliminates black clipping.The only downside is that this player has lag issues.The sound lags behind the video making it useless.
[Galaxy Note GT-N7000 General] PaulF8080:
That kind of shoots down my scaling algorithm guess. Is there no banding in a screen cap?

I convinced myself that scaling up can't work on a color gradient that steps the neighboring pixel by adding an integer 1 to the color numbers. The Note has more pixels so you have to add pixels in between and you can't increment less than 1. Assuming I am making sense, where did I go wrong?
[Galaxy Note GT-N7000 General] QuadLight:
To adjust render quality in ICS (official firmware) select chechbox - "Force GPU Rendering" in settings - develorer options and reboot device

Now you can see "1" in gammatest picture in quickpic
[Galaxy Note GT-N7000 General] Tinderbox (UK):
I thought the less numbers you saw on the left side of the test pic the better, seeing more should be worse or do i have this back to front.

John.
[Galaxy Note GT-N7000 General] QuadLight:
"1" must be visible - allways.

But problem amoled screens (with incorrect callibration profiles) show it too bright or not shown.

my friend in GB can see only 4-5-....

after voodoo R&D 2-3-4... but it more darker

after ICS and Force GPU Rendering he can see "1" but only in absolute dark room or night - this is correct !!

but anyway gamma little wrong

all who have black blocks in video or artifacts - go to samsung service - and replace display module.....

supercurio upcoming apk is not solv your problem - its real hardware problem with gpu

it can be particaly solved by software tweaks but not complete
[Galaxy Note GT-N7000 General] Tinderbox (UK):
This thread seems to say the opposite.

http://xdaforums.com/showthread.php?t=1559800&highlight=black+crush
[Galaxy Note GT-N7000 General] onetonnoodle:
You are wrong about this. It should be "darker" on the left side with even transition of gradient. You can check it with your computer/laptop screen by viewing the gamma test png file.
[Galaxy Note GT-N7000 General] paleh0rse:
You realize the goal is to NOT really see box 1 in the gammatest, right? In fact, most of the left side of the test image should be too dark to see, and you definitely should not see too much of a contrast difference between any two adjoining boxes -- especially between 0 and 1. The transition from black to grey is supposed to be VERY gradual, so much so that the left side of the image should be mostly "black."
[Galaxy Note GT-N7000 General] paleh0rse:
you're mostly wrong.
[Galaxy Note GT-N7000 General] kusanagisan18:
I get that this is wrong for the gamma numbers, but what about sending the phone back to get it fixed if we see these splotches and black blocks?
[Galaxy Note GT-N7000 General] noteworthy:
Just updated to ICS and it has made no difference to the black rendering.No better or worse.

Checking "force gpu rendering" makes it worse.It is not a solution.
[Galaxy Note GT-N7000 General] Tinderbox (UK):
I sent my first one back, the second was much better, some have taken four or five swaps to get a good one.

My new good one, had all the updates already on, and it had a stylus video, i don't remember the first one having that :confused:

So try to get a new stock one, how you do this is another thing, i just waited a few weeks and then ordered a new once, as the price had dropped and i though i would give it another go as i really like the note.

John.

---------- Post added at 06:09 PM ---------- Previous post was at 05:57 PM ----------

I had heard that ICS made not difference to the black crush, but that it did reduce the graduation problem, that you can test for using the calculator app.

Though still on GB, and both the black crush and graduation, are a lot better than my previous note, though still not perfect.

Having watched a few movies and series on my note now and i can now resist the urge to throw it off the wall now. :)

I just hope ICS does make the quality worse once it is released in the UK, whenever that is. :(

John.
[Galaxy Note GT-N7000 General] noteworthy:
Banding has improved after updating to ICS.I no longer see any banding in Angry Birds Rio.There still is banding in the calculator but has improved.

The black rendering is mostly a problem with the gamma curve set too luminant.I suspect Samsung has setup the Note to be highly viewable in bright environments where most Notes will be used.Only a very small percentage of users will be watching movies sitting in the dark.The Note has a very luminant display and the gamma curve is the culprit.

However,I suspect even with the gamma curve set correctly,the black rendering problem will still be there albeit much less noticeable.It just might be a limitation of the pentile amoled technology.
[Galaxy Note GT-N7000 General] clandestino123:
Well, my wife has an SGS and there are no black clipping problems. I won't pretend to be an expert in this field - but I don't think this is a hardware issue at all.
[Galaxy Note GT-N7000 General] noteworthy:
The GS2 does not have a pentile matrix display like the Note.It has a proper true HD RGB display.The S2 is also not as luminant as the Note so the gamma curve is set correctly.
[Galaxy Note GT-N7000 General] clandestino123:
Not really sure why you are mentioning the SGS2 in this thread?

As you say, the SGS2 has a different display from that used in the SGS and the note.
[Galaxy Note GT-N7000 General] EdgaBimbam:
lol sgs and note screens are also different...
[Galaxy Note GT-N7000 General] noteworthy:
No,both the GS And the GS2 uses an RGB display so my point is still valid.

The Note and now the GS3 uses pentile matrix.

edit: Sorry,I was incorrect about the GS having a RGB display.It is also in fact a pentile screen.
[Galaxy Note GT-N7000 General] Barkotron:
GS was pentile too.
[Galaxy Note GT-N7000 General] clandestino123:
I thought that the technology being used is identical? Size and resolution are different.
[Galaxy Note GT-N7000 General] eRode:
Another one of his vapourware lol
[Galaxy Note GT-N7000 General] pboesboes:
I don't see how black levels have anything to do with the subpixel layout... Banding, I can understand.
[Galaxy Note GT-N7000 General] Tinderbox (UK):
It has to be an hardware issue, my last note had terrible black crush, my new has hardly any, both are running the same software, unless it`s the display controller software, that`s maybe not normally included in an update.

If it is a calibration issue, every note is going to need an different calibration profile.

I have had a few hardware calibrators to do my notebooks screens, and it made the colors really washy, for anything other than photo edition, i crank up the saturation.

John.
[Galaxy Note GT-N7000 General] slinbin:
My note had absolutely no isues on stock GB

Now I am on stock ICS and I have terrible bandings in blacks.

Setting screen mode to "standard" helps but does not solve the problem.

So my take is that the problem resides in the software settings
[Galaxy Note GT-N7000 General] Tinderbox (UK):
I have been worried about the ICS upgrade, making the black crush worse :eek:, what do you do then after you return period has run-out.

I am going to wait a week or two after ICS is launched in the UK, and see what problems arise if any with other peoples notes, but ICS has all the new apps for the pen and that, it`s going to be hard.

EDIT : are not black crush and banding different, just you say black banding?

John.
[Galaxy Note GT-N7000 General] betoNL:
In the meantime, I think Supercurio just forgot/ gave up the GNote a long time ago...

I haven't been following ( Forums, twitter, etc.) so I wonder on which device(s) he is busy right now

Gladly I have one of those GNotes with a good screen...just some black clipping in some videos.....

.
[Galaxy Note GT-N7000 General] paleh0rse:
Supercurio posted the following in this thread just 7 days ago:
[Galaxy Note GT-N7000 General] betoNL:
Oh yeah, now I remember...

He said sometime ( I think) he was waiting on the ICS source codes...

It is not just I havent been following, my memory also sucks :rolleyes:

[Galaxy Note GT-N7000 General] liutszho:
If that is true I hope its in progess!
[Galaxy Note GT-N7000 General] black818pro:
really hope that this screen issue can be settled or improved. look forward to good news soon
[Galaxy Note GT-N7000 General] jezza333:
Quite frankly, I'm over this rubbish. I'm done waiting for supercurio, I'm done hanging on a limb waiting for some magic fix that supposedly he'll decide to release one day. And I'm over the superiority complex that seems to surround him; granted he did some great work but pride stinks and he can keep it.

I'll simply get the Note 2 when it's released and sell the Note 1; heck, I've waited since October until now so I have no issues with waiting a few more months.

Case closed for me. ;)
[Galaxy Note GT-N7000 General] Dark Sol:
I want this to be fixed SO MUCH
[Galaxy Note GT-N7000 General] Rezz:
No need to talk him down like that, its not like its an easy thing to fix so lets just wait and see what happens.
[Galaxy Note GT-N7000 General] Dark Sol:
just a note : with the voodoo adjuster if you pull it to the left my note goes completely rubbish with black turning purple or whatever. If i pull about 80% to the left i cannot see pattern 0-8 at all . Completely black.
[Galaxy Note GT-N7000 General] lagittaja:
Updated to the polish ics (lpy)

Banding is still there but the black blocks in shadows have reduced a tad.
[Galaxy Note GT-N7000 General] Dark Sol:
a tad is kinda not enough i guess.. my note shows complete rubbish.. i am gonna go back to the shop and see if i can find a good one..
[Galaxy Note GT-N7000 General] lagittaja:
Yeah it is not enough. It is still blocking quite a lot but it is not as bad as it was in GB.

Hopefully supercurio can come up with a solution at somepoint :)
[Galaxy Note GT-N7000 General] Dark Sol:
Just for reference - i have a french note. And it shows like total crap
[Galaxy Note GT-N7000 General] skorpioneMM:
No news...
[Galaxy Note GT-N7000 General] drake19:
The only thing that im reading in Supercurios tweets its about the new voodoo sound louder that is making for GSIII!!!

He hasnt answer to any of my tweets about the GNote and that app for the screen,nothing at all,so im not w8ing for him either,i care about it anymore and im gonna go to the samsung service to change the screen,thats it.

But if he was making any progress he will told us,but nothing said about the progress!!!
[Galaxy Note GT-N7000 General] pingling:
To see how much the banding problem was improved in ICS I've made a very quick comparison of three apps in GB and ICS - http://photobucket.com/n7000banding. Just open pictures in full size to see them properly, otherwise the browser may distort them. While some of the banding is still there (exit screen of ABR, red background in Bag-it), the improvement is really BIG. It maybe also fault of application that some banding is still present.
[Galaxy Note GT-N7000 General] Dark Sol:
much better for sure!

[Galaxy Note GT-N7000 General] PaulF8080:
Do you use the XDA app to read the forum? I'm still wondering why the banding in the XDA app splash screen. Anyone know where the splash image is stored on my phone? Or the apk?
[Galaxy Note GT-N7000 General] Markuzy:

He actually mentionned that the.banding and black crunching are solved on the SGS III.

I wonder why not on our beloved SGN .
[Galaxy Note GT-N7000 General] eeyunopper:
It seems as if this issue will not be fixed by Supercurio, probably because he has moved to a new device, or he's pissed at some of the rude comments earlier in the thread. Would be nice to know either way though.

If not by him, surely someone with "the knowledge" can work on fixing it. I'd gladly pay £25 for this fix....

Maybe we could start a bounty threadand hunt for a programmer?

[Galaxy Note GT-N7000 General] PaulF8080:
My first opinion was if a guy with a colorimeter can't fix it no one can. I kind of still think that, but only with driver help from Samsung.

I worked for a company similar to Samsung and occasionally a bug would be "roomed". The bug could only be talked about in a restricted access room. Talking to Samsung may be futile.
[Galaxy Note GT-N7000 General] Spo0f:
So, if i use BS player for an example, the video quality is great. When I do this with youtube for an example - black looks awful.

I also generally have blended colors in games ...
[Galaxy Note GT-N7000 General] hagba:
I think when the light is too faint on all switched off screen (which means total black out in the Amoled screen case) the power is not enough to wake the pixels on in a uniform way but it does it randomly since the pixels are too big on a large screen , so the bloating appears.

I think its a hardware issue, more pixels should solve it since it means smaller pixels lower voltage.
[Galaxy Note GT-N7000 General] drake19:
Man you have wrong and i will tell you why,the issue is software,today i have download Multipicture Live,its an app that changes wallpapers every 30sec,and in options it had image quality 16bit and 24bit,i set it to 24bit and vouala no black cliping on photos at background!!

So thing is that samsung software using 16bit of colors and not 24 or 32bit!!

I test it to 16bit and then i saw the black clipings again at background!!
[Galaxy Note GT-N7000 General] hagba:
Actually I dont have any black cliping or bloating or whatever anywhere on my device except when I use the Camcorder to record a video and that is under very low light,only then is that I have noticed that the light emitted was not powerful enough to awaken the sleeping black pixels except randomly which caused the phenomena.
[Galaxy Note GT-N7000 General] Latoc:
Supercurio is finalizing his DisplayExpert application.

Even though he doesn't talk about the Note on his twitter posts, he has mentioned a few devices, like galaxy tab 7.7, S3, etc...

So it is entirely possible that his app will take care of many devices, including the Note.

I don't think he worked that hard on the Note's display to just throw his work in the trash in the end.

I remember reading one of his tweets a few months ago saying something like:

"With proper calibration, this is the best mobile display on the market right now".

He has the knowledge and the skills to bring our displays to the max, so I have faith he will do it.

Of course, I don't know what Supercurio is really going to do so this is just pure speculation on my part, based on a few gathered facts.

Let's keep dreaming guys !!!
[Galaxy Note GT-N7000 General] liutszho:
Hey guys just wanted to share my workaround.

I downloaded Tasker and setup a few automated tasks with Screen Adjuster when I watch videos on tubemate or mxplayer etc.

Basically whenever these apps open screen adjuster does too and I enable it and press back key to go back to my video.

Then I turn off screen adjuster with the widget in my home screen when I am done. Since I press home anyways.

Btw I am a total Tasker noob so if anyone can improve on this. Please help. I would like to make this automated whenever I open mxplayer etc but I dont know how to do it.

Here are my profiles and Tasks in screenshots. I dont know how to export Tasks out.

Well guys.... 6 month ago i talk all of you - supercurio never solve problem with Galaxy Note screen - Voodoo R&D this is all what he can.

First, he promised us all release the application immediately after writing their own system - an alternative to Google Play

Late - As soon ICS will be released

he had forgotten about it

Now he Promises in his blog - "Soon and free but for Galaxy s3" - Just because that is easier to do all for s3 -

Now he promise - "Sometime later for Galaxy Note" - I think it will never happen

no Alfa or Beta or PreRelease version of Display Expert for Gnote - nothing. Its realy Very bad

Galaxy Note2 will be out - winter 2012-2013 - trust me - he next post will be something like - "I see no sense to develop an application for a device that is no longer relevant"

I am currently on GB unrooted because I don't know if I should change my Note while it's only 1 day old, or ICS should fix it.

I did about 3 hours of research, but is it confirmed that it's either a hardware or software problem?

I love my note, I don't want to get rid of it... because if it's a hardware I'm going for a refund and wait for the next version of the Note.

Also, the three first are actually pitch black, not varying degrees.
