No this is not another one of those "I've got a screen issue" thread, For those who still have their Galaxy S1/S2 or even a Samsung Wave, how deep are the blacks on the Galaxy Note compared to them?
I ask this since I no longer have any other SAMOLED device aside from the G-Note and I noticed that the black levels are not very deep, infact they are like LCD's with backlit when you view an all black or watch a movie/picture with a good majority of blacks.
Can anyone be so kind as to test and compare in a dark room showing the phone stock test image found under *#0*# ( dialer ) I've been getting reports from other users that the black levels on the G-Note is not as deep as the S1 or S2, Trying to figure out if this is normal or some really bad gamma issue/hardware limits.
Since there has been a HUGE failure of people reading or understanding what this thread is, it is not a complaint thread its more of an inquiry thread on what you are getting with your screen. Those who dont have a previous SuperAMOLED device you guys cannot contribute anything on this thread since you wont have any basis of comparison so please stop trolling.
Darker than a black steer's tookus on a moonless prairie night.
Anyone else with a meaningful post comparing the S1/S2 vs the Note in black levels?
Like any other OLED technology, there is no backlight, so the blacks should be as black as if the screen were off.
What you might be noticing is fringing, the light leaking out from the neighboring pixels.
It could also be an optical illusion (you are seeing a black object with lighter surroundings it might make the blacks "not seem as dark"), I tested it myself, I got an opaque piece of paper with a small hole in it and placed it against a black part of an image, and compared it with the screen off. It looked the same to me.
I can't compare it with the S1 or S2 since I don't have them, but with as with any other OLED screen, as long as the black parts of the image is truly digitally black, as in that part of the picture is 000000 on the RGB color model, it should be equally black as if that part of the screen were off.
No difference in the black levels when they are properly rendered on the note vs gs2. The software bug though sometimes makes blacks grey so viewing the same video on both screens dark areas look better on the gs2. This will be fixed with an update and as others have said true black=off with oled so black will be black on any oled screen.
In gallery i get true blacks and images look the same on both screens apart from much bigger and sharper on the note. If i make this image a lock screen its sometimes grey with banding on the now instead of true black.

Don't know about black, but the screen it's forkin bright, too bright for day time use even on the lowest setting
The Black arent 100% fully black. If you turn the lights lights of you can see some very very deep grey. It black enough tbh, I am not complaining!

If you have a phone with a SAMOLED screen go to a black room and bring up the LCD test menu, the black is at 000000 and you will see a faint glow, you can very easily tell if the screen is displaying a black color or if the screen is locked. Why websites say their testing machines report infinite contrast ratio is beyond me.
If you cant tell the difference of the screen displaying black and when the screen is locked ( off ) either you got the most absolute perfect screen or you need to actually check rather theory craft.

The main point of my question is not about "when rendered properly" just bring up the LCD test menu on your galaxy note and galaxy S2 and check if the note has a higher glow on its black levels. mine is extremely high from what I can remember on the Galaxy S2, infact I can label it an an LCD backlight instead of SAMOLED blacks. But if im in daylight the blacks are pretty good.

Its not about complaining, I just wanted to ask for those who have the note and also have the S1/S2 to make a comparison if the black levels are similar.
Im at a loss as to why this feat is extremely hard for the people who replied on the thread so far, I guess I am asking to much.
No one has the S2 and S1 and the galaxy note. why would they? the note is amazing!
Galaxy Note black has more leak than previous Super AMOLED and Super AMOLED Plus screens.
I'll come up with measurements a bit later.
well, Kabayan i have both... i can confirm your finding that S2 does have deeper blacks... last night i viewed the Dota2 trailer video on S2 and Note side by side... @ the beginning of the clip where there are lots of black displayed, its noticeable in my eyes...
I decided to create a pure black wallpaper on photoshop, transfer it to S2 and Note, set both brightness @ max, go to the complete dark room and view the mentioned wallpaper on gallery; its positive that S2's dsplay shows deeper black than Note... Though i have the display tuning app by SUPERCURIO on my S2 which i think we'll also consider...

An OLED display works without a backlight. Thus, it can display deep black levels and can be thinner and lighter than liquid crystal displays (LCDs). In low ambient light conditions such as dark rooms an OLED screen can achieve a higher contrast ratio than an LCD, whether the LCD uses either cold cathode fluorescent lamps or the more recently developed LED backlight. Due to their low thermal conductivity, they typically emit less light per area than inorganic LEDs.
When the display is "showing" black, the "black pixels" are actually inactive. In other words, the black parts of the screen is off.
The black levels on my screen is also 100% black. If i go into a dark room with a 100% black wallpaper, i won't see the screen.
I have an S1, S2 and Note. Showed all 3 at Samsung service centre just to prove the Note's screen was crap. Should be getting it back to day with a new screen. The S1 screen still seems the best in terms of brightness and uniform white.

Yay supercurio. It's good to see you.
It does have more light leak on pure blacks, but coming from an Atrix (LCD) and an S2 (WVGA), I still love this display the most. The resolution is insane.

Did you happen to get a photo of it?
I compared both with a clear black test screen from walvisions.com min and max brightness blacks where the same to me. I must have a perfect screen or you have a very bad one.
But like i said in my previous post the blacks when actualy in use watching a dark video are much better in the gs2 for what i think is a software issue as they arent rendered properly and dark areas tend to look more like backlit lcd on the note when viewing videos.
Whites are much brighter on the note with min brightness settings then on the gs1.

It is not true, you really should try it before just quoting wikipedia or whichever website that quote came from. Even with a perfectly black image you can easily tell there is backlight.

This shows me what you know and how much visual acuity you have when it comes to things like this, I mean no disrespect or in anyway be offensive to you but I dont believe that its 100% black on your end. But I respect your opinion. Thank you.

Very true, the S1 screen was really great.. it really brought the expectation level at an all time high.
There's a lot of variation on the screens we are getting, my Galaxy Note screen has no color variation, banding, dead pixels, and the blacks are real black. In a dark room, displaying a black image, I can't see the limit between screen and plastic bezel. Exactly as with the screen off.
The same with video playback. I recommend to use BBC One Human Planet trailer in HD. It has a lot of colors and transitions to black screens. I see the screen completly back, no difference to the black plastic bezel.
This is a black Galaxy Note, on a black background displaying a mostly black image. Brightness set to maximum.
Now you tell me you can see the limit between SAMOLED screen and plastic bezel

No color variation is plausible, banding is SW issue so nobody is excepted from it unless you can prove it, dead pixels are pretty rare that its a non issue, black levels are lit let yours eyes adjust to the darkness for 3~5mins and you can clearly see a lit black its always been like that since the SGS1 days, your phone is no exception.
Your screen is perfect for you, I respect that and Im very happy for you, wish I had that screen. Cheers!
Response to your added image:
Your image proves nothing since the discussion is about black levels in total darkness while displaying the black image from the LCD test, your picture shows an image displayed making an illusion that the blacks are very deep, I also get the same black levels when im displaying even just a few pixels of white and you have ambient light since I can clearly see the bezel.
Basically we are comparing 2 different things but thank you for trying.

Seriously who uses a phone like that and whats the point of that test. OLED does show a little light in the dark when you do that but my GS2 and note are pretty much the same, during this test I notice some darker blotches on my gs2 screen. Does that mean its faulty? not to me as Ive never noticed it in real use and thats what the device is for not to sit in the dark for 3 minutes to find some obscure issue to complain about.
There are real screen defects that will occur to some people not matter what device you get, then get it replaced. There are confirmed software issues and these will hopefully be addressed soon enough.
Many more people have no physical issues with their screens then the ones that do but its funny how some people just wont accept that and have to believe every screen is faulty.
Seeing a little light through a screen in total darkness is not a hardware fault, maybe you should turn off your phone as it will save your battery and at the same time the screen will be perfectly dark, I prefer to have my screen on and use it but we all use our devices differently
I often see color uniformity issues on amoled panels especially on whites or in greys. For those who have a keen eye and know how to check, how is your screen uniformity? Post some pics on what image you tested it with.
I've had 2, I'm a printer( so see everything?) and have noticed the screen to have the top edge red and bottom green, sent one back but the new one had the same thing. Any one else notice it? Or maybe I should get some 3D GLASSES ?
Its a very common quality control issue on AMOLEDs even on the latest Note 7 it is still an issue, Aside from the Galaxy S1, I have yet to see a uniform AMOLED panel especially in whites and greys.
Hi all,
I would like to get some feedback on the AMOLED display quality in regards to uniformity when displaying a grey screen?
Did Samsung improve anything here or do the AMOLEDs still have clouding issues and the displays are not really uniform?
This can be seen using OLED tools with dark green or dark grey.
I have a Tab S3 and Tab S4 both with some clouding visible especially when displaying grey and dark grey.
Got some feedback that the S7 had also some issues. So any improvement with the S8+? Would like to upgrade, but would like to have a flawless display.
Thanx in advance,
am
This is all I could find.
Thanks for your feedback. It describes some older panels. Question is if the screen unifromity is better with Tab S8+ or if there are still issues with dark grey/near black as with previous devices.

That page is old. It refers about galaxy tab s generation 1 I think, about 8.4 inch and 10.5 inch one, it does not talk about new s8 series.
Looking to buy S8 as it is comparatively more compact & cheaper.
How is the overall quality of LCD on S8? Does it have any accuracy issue like warm tone?
Thanks

S8 has got TFT panel instead of OLED like s8+ and S8 Ultra has got.
Screen quality is better than Tab s5e
(especially if your have allergy and tears on Amoled)
UPDATE: screen is amazing
Screen of S8 is good, it's a TFT screen but is consistent even in the edges of the screen. Only issue i got is that Samsung doesn't have adaptative warm tones on panels that aren't oled, also don't expect perfect blacks.
It's great. I have no complaints with it.
Great quality (Samsung galaxy tab s8 ultra ).

He is asking for s8 which hasn't oled. S8 ultra has oled. If you like oled, you don't buy s8 regardless how good is the screen, it isn't oled..
You are right Sosimple, i respond to quickly. Sorry for that.
I've a Tab S8 since some months. The screen quality is excellent. It is a LCD display , one of the best.
In the past I had also a Tab S7 plus with amoled but I like more the Tab S8 because of the size. The LCD allows also better energy consumption compared to the amoled.
I may suggest to buy also the keyboard with trackpad (the one made for tab S7 , not the recently released version without trackpad) . It is a nice accessory that transform the tablet into a semi Surface expecially in the Dex Mode.

LCD takes actually more power than amoled/oled. Since black on amoled/OLED has got leds turned off which takes less power on black areas. While LCD keeps leds on and mixes colours into more like grayish black.

What you say it's true but S8 battery life is much better than S8+ (according to what i saw on the internet), this might be cause S8 is the only one with adaptative refresh rate
