Super Amoled question...

Happy new year everybody,
I was wondering about the energy consumation (do i write that right? Sorry I'm from Germany) if the Galaxy S' SAMOLED. I watched a Video and noticed that the Black Colors look exactly the same as when the Screen is turned off.
So my question is: Does the phone turn the Blackpixels of so that they don't use any power?

You are absolutely correct, it preserves your battery to make it last longer.

SAMOLED still displays backlit blacks, you can test this by making a pure black image and store it into your gallery and go into a room thats complete dark while you have the black image on screen, lock the phone.. see the HUGE difference.. the blacks on the SAMOLED is good but no where close to true blacks.

Thx for the hint EarlZ. Now I can see the difference.

[Q] Is there a gNote WITHOUT black clipping/crush/color rendering, etc.??

The question is simple: is there a Note with a good screen? Simple test: is there a note that shows 11 as a first noticable number on this picture? (If you can barely discern below 11, that's fine)

You have to be in a dark room to test this. I tried 7 different Notes and they all show from 4 and one from 1.
(tried this on an S III and it shows from 11)

yes it shows

a person with a Note (or S3) without the black clipping issue would be very lucky. it's hard to find a stock that has a perfect screen. it is after all the sickness of SAMOLED screens.

Yes, I know, but there are many people claiming to have no issue at all. Here is one YT video that shows 90% reduced black clipping

So, there is hope..

I've read somehere in our Note's forum that just by changing kernels on your phone would change the MDNIe on your Note, thereby decreasing the black clippings on your phone.

lol pixelation in dark areas is that black crush, or not being able to read a specific number because screen brightness/contrast/gamma is low?

Mine looks fine but how does this prove that my screen is fine? Gonna watch a 'dark' video and see if I do get the black crush, I don't remember if I do or not.
Edit: Mine is all good!

Post a picture or it did not happen. Test in a dark room. Proofs needed:
1. picture with the numbers showing on the screen
2. Take a picture of the calculator running
Don't use screenshot, you have to take a picture with a camera

It is crush or clipping. The settings of the screen are set by Sammy to pull all values to zero after a certain threshold like 4 in that pic. They do this because they think it improves contrast. It is stupid, and even more stupid on an OLED screen that has good black levels anyway. It is not the "screen" as in hardware, it is the way the low level drivers are set.
The right way to do it is to ramp down smoothly to zero with zero the only level that shows nothing at all (pure black).

Nexus 7 causes eye strain :(

Hello, I own N7 3G version and I have very annoying problem. My eyes hurt when I read texts. They look little bit blurry and the white is too saturated. I noticed that the greens and yellows are very pale compared to my LG OPTIMUS Black that uses LCD too..Is it me or my device has bad display?

Try screen filter?

I used to use screen filter, but I ended up shelling out for Lux Auto Brightness. It's just so much easier to use. I thought Screen Filter was a hassle and it needs to be disabled in order to sideload apps because it won't allow you to click the install button if it's enabled.

Lux does that too, but it's smart enough to disable itself for that short time you're installing.

If the text you are talking about are web pages, you might consider getting the (stock Android) Browser.apk out of a AOKP build that matches your ROM base (4.1 vs. 4.2) and installing that in addition to Chrome (if for instance you are using a near-stock ROM).
The one thing that was an immediate disappointment to me for the N7 right out of the box was with the Chrome browser's lack of text reflow when zooming.
The Stock Android browser does text reflow nicely, so there's less eyestrain looking at larger text. Nicer bookmarks than Chrome IMO, too.
It does seem a little more prone to crashing than Chrome - but I use it anytime I want to read web pages where zoom+reflow makes the reading easier.
cheers

Silly question but have you thought about going to the optician? Maybe you have bad eyes and need corrective glasses.
From my Nexus 7

I'm short-sighted - that means I see close objects fine opposed to distant objects. I'm corrected with glasses Anyway. I don't have such issues with ipads, xoom despite the bad PPI of the latter. The color reproduction is wrong with nexus, especially the black fonts on white background - they look too grayish and blurred and kinda blend with the oversaturated white background. Interestingly reds and blues look fine on white background; the same is valid also for the white texts on black background. Not to mention the device has very weak greens and yellows even compared to many mediocre LCDs. No ASUS again

To answer your question. I've used my N7 heavily....hours and hours every day, for all kinds of tasks, and have never experienced what you describe. Each person is different, it sounds to me maybe you're sensitive to something on the device that few others are...maybe its the high PPI? Go try an iPad Mini

I think it is the scrolling, wat makes my eyes hurt. The tekst is building up in a way that I have to focus again and again. The xda app is a example of it.

I get big eye strain using the N7, especially at night !! But only one white pages. This aint just the tab though, I get it from my computer screen also.
Is it normal to be getting eye ache and headaches from whites onscreen?
I ended up getting a browser (Maxthon) with nightmode for my tab, but doesn't help for the PC.
Any ideas how to cause less strain to myself? My brightness is low etc.

for your computer download and install F.lux - at night your eyes will thank you. it takes ~15-30 minutes for your eyes to get adjusted to the color shift. If you really want to see the difference it makes after using it for 2-3 hours at night, disable it and see the results for yourself.
Anyone know a good flux alternative for android? I would assume if they have a jailbroken app for ios they should have had a android .apk.

[Q] Color (black) scale on GT-N7000

Hey there,
I just bought a GT-N7000, and I am quite dissapointed with the display quality. I have a lot of experience with Super AMOLED (plus) screens from Galaxy S and SII, but I am facing an issue on my new Galaxy Note.
You can see it on dark pictures, photos or mainly videos. It looks like the screen on the Note were more sensitive of brighter tones of black then the screens on S or SII. Let's say I am watching a video. If the scene is full of light, everything is all right and you can definitely see the breathtaking quality of the Super AMOLED screen. But when the scene goes dark - everything got different. On the S or SII, all the dark led pixels were inactive, so the screen was absolutely black on dark places. But, it looks like my new Note is a lot more sensitive of light, and the result is, it finds a not-absolute-black places all over the screen, and the scene is not Black at all. There is around 50% of the screen's area which is not Black, but just dark grey, consiting of small squares. Also, these squares flicker in a very high frequency, which makes it even more annoying. This is also happening with photos taken in dark, but, of course, the squares are stable.
Are you facing this issue too or am I the only one? I hope you did understand my words, if not, I could provide some photo samples of what I'm talking of.

This is called black crush and present on all Note 1s to varying degrees. Samsung refused to acknowledge it as an issue.

Search for the thread in the n7000 forums with 'black clipping' in the title If you don't find it as black crusg. Lots of good reading there. You will find all the info you desire in this topic.

What screen mode are you using?

As with previous Samsung devices you can choose between various display modes, some are more accurate than others and different people prefer different look. Which mode are you running?
Adaptive display- Far too saturated colors, white point is too high(blue)
AMOLED Cinema- less saturated than Adaptive display but white point is still too high
AMOLED Photo- colors are slightly too saturated, white point is pretty good(right around 6.5k).
Basic- This is suppose to be the most accurate mode according to display mate but the UI and icons look washed out(perhaps because the UI colors were designed with very high saturation in mind?) . This mode is great for photos and videos though.
Update - I've started using basic mode. It took much longer than expected to get use to it but once I did I won't look back.

I'm using cinema as I think it looks the best

I personally always go for the most technically accurate, which is funny cause it's called basic mode lol.

I just use adaptive. Then it aaaaaaaaaadapts. Which is fine. Basic is too washed out for me. Maybe Ill do a week basic and see if it grows on me, though.

I don't think adaptive display does a great job at adapting lol at least not from what I have seen....I've compared Note 4s side by side at work and adaptive doesn't really seem to adapt at all regardless of the type of media that is being displayed, still looks far to saturated and the white point is too high. Some people like that though which is why it's set to that by default.

I though the same thing as well, at first. Cinema mode looked more like my Galaxy S4 which I was use to. I decided to give photo mode a go though since its significantly more accurate and it grew on me after a few hours. It takes a while for your eyes and brain to readjust.

Yeah I think I'll try out basic for a while and see if it grows on me.

I've just switched to basic. I used the equivalent of it on my Galaxy Tab 7.7 which also had an amoled display and I soon got used to the correct colours. Every time the phone rebooted it would start in the default before switching and you could see just how over saturated the colours are.

Yeah, same here. After using the stock color mode for years, it took me a while to get used to the accurate colors. But once I did, I could see the difference in how over saturated the colors were on stock mode. But it's definitely a preference, some people like the colors to pop.

Oversaturated colors are the best thing about AMOLED in my opinion.

Still using basic here. HAHAHAHA. But planning to try Cinema soon

I use adapted display. Don't care how accuracy color is Basic, it just wash out to me.
Cinema is crazy saturation.
Photo mode a bit yellowish, too warm.

I like cinemas cool color as photo is too warm for my tastes. I never use adaptive and basic looks off to me.

Trying with adaptative... will see how it behaves or I'll go back to Cinema.

Cinema for the best white.

Using Cinema, loving it!

Do you think adaptative display, for obvius reasons, consumes more battery than the others?

I use photo for now because I like the high saturation that comes with it (it's not that high anyway since I use it dimmed back a bit).
