People were talking about Srgb in the nexus 6p .. I tried it and the colors looked weird to me. Why would I use this feature ?
sRGB is a method of rendering colors to which the colors drawn are, in a sense, more basic and more true to the central RGB color matrix. Newer display technology is capable of rendering a wider range of colors which can increase saturation and give things a more "popping" visual as they are "truer than life". Using the sRGB setting will tone down those exaggerated colors and bring them closer to what you would see in the real world. I doubt you would see much if any performance impact be it positive or negative to the processor or battery since the technology being used can handle these varieties of colors easily. So if you find your screen to be more appealing in sRGB mode as you like LCD-like visuals versus the heavily saturated Samsung-like AMOLEDs, then you may benefit from using it. In a real-world application, I can see it being useful for seeing how your photos would really display on print or a standard LCD screen as it is reducing the range of colors and saturation created artificially by screen enhancements.

Hello.
Anyone else noticed that the display is lower quality than sgs ?
I mean in terms of gamma.
I am a photographer and I was amazed how good the contrast and brightness f the first galaxy was, however this one seems to have way too big contrast, making everythig that is dark much darker, giving a fake and strange appearence.
Also the auto brightness in general is lower than sgs.
Does somebody know if it can be tweaked through a kernel recompile, like sharpness and color in voodoo ?
Go to options-->display-->uncheck automatical screen power adjustme(don't know the exact english term, got it in dutch). I bet it is this again...
Let me know... you're not the first one.
No, it's not that but thanks
It's the actual gamma of the driver I think
However I did notice there is now a "background effects" that can adjust saturation and hue so there is access to the drivers. Maybe a bunch of new effects added there like "classic gamma, normal saturation..."
I came from the captivate, and ran just about every rom that was out there. One of the ubiquitous mods was the color fix. I noticed when I first booted the SGS2 up, the color was off (in relation to my expectations) sure enough in display settings there was an option to change it. Without looking I believe it's called "cinema", which perfectly returned that color richness I loved.

there is something wrong with auto brightness , it doesnt work very well , but its not true that SGS 2 has a lower quality display than sgs , Super AMOLED Plus displays are an upgrade to Super AMOLED. They use a real-stripe subpixel matrix and not pentile - and so has 50% more sub-pixels. The PPI is a bit larger but Samsung will soon make them at much higher resolutions. Super AMOLED Plus displays are also thinner, brighter and use 18% less energy than the older Super AMOLED displays.
Bought the 10...love the way it runs but I bought it to show my photography work on (would use an ipad but I really detest the ios software).
The entire screen seems to be washed out overall with weak black levels and reds in particular are low saturation.
Sharp as a tack for sure....is it just mine? I see such conflicting reports in reviews although I am seeing more now about low saturation and contrast.
Very frustrating....unless someone out there knows some way of calibrating this display which I haven't found?
you are right
i am also a photographer (Canon 5D MkII)
i have watched some photos now(got my N10 yesterday) and as you said the screen is sharp as hell
i have never seen this amount of details with my DSLR photos.
im also doing hardware calibration and i see whats wrong right away and i have also tested it...the problem is that the gamma is to low.
The N10 has a Gamma Level around 1.4 - 1.5 where it should be 2.2!
(yeah that should make some attention hehe)
thats a fact and thats why we have washed out colors and bad contrast
but the good thing is that even at that low gamma we have a decent picture quality with good black levels!
i dont think the black levels on my device is washed out
it shouldnt be this good with this crappy gamma but it is
thats amazing and that tells that this is a quality screen above normal.
with correct gamma at 2.2 this screen will rock for sure.
so lets wait for some kernel guru to make some gamma adjustments
i have said i before that im willing to pay that person that makes gamma adjustment possible for the N10s.
You are correct...gamma is definitely too low.
As far as washed out reds go, I suppose I could process specifically for display on this tablet but that's a pain in the butt.
I wish the darned ipad wasn't such a restrictive ecosystem for the software. The colors rock on the ipad unfortunately but it's just too darned restrictive.

im waiting for a i1 Display Pro colormeter
when i get it i will do a hardware calibration.
but i have checked some stuff already and i think that the colors is right for its low gamma.
also the brightness for the colors seems the same for Red/Green/Blue and thats a good thing
also the contrast and black level is reference.
i also think the color temp is close to 6500k
that means that the grayscale is correct.
so the only thing that messes up this display is the low gamma.
(or wrong gamma curve/line)
you have some tests here that you can do without a colormeter,if you want to check it out
http://www.lagom.nl/lcd-test/
also you can download the AVSHD 709 Patterns here.
http://www.avsforum.com/t/948496/avs-hd-709-blu-ray-mp4-calibration
just copy the mp4 files to your N10 and run them.
one note that i can see is that it seems that the gamma is higher at the lower shades
it seems to be around 1.8 there
that could explain why we dont have completely washed out blacks.
but what you want is a plain straight gamma line at 2.2
the N10 seems to have a hill shaped line starting high at lower shades and lower around maximum white.
I have tested the N10 with a Pantone "hocky puck" and can confirm the observations posted above. As compared to overly saturated profiles most normal users are used to, it's no wonder many see the N10 as flat and dull. My N7 is horrible, not only flat but had a color temp that was blueish green.
Much of my publicly displayed work for general web based consumption, has the saturation pumped up farther then I like, but my "fans" (sarc) seem to enjoy my photographs when contrast and saturation is pushed high. Ironically, my over saturated photographs look good to me on the low gamma N10, lol.
Either way, most all of us would benefit from being able to adjust our N10s. As many of you know this is best done at the kernel level and the master of sound and color Samsung kernels is SuperCurio and his project Voodoo. I have heard hearsay that he is working on kernel code and color profiles that can support adjustments for the N10, but I have yet to confirm this myself.
As usual we are given hardware that needs code improvements to be fully realized and that seems to always be done by the development community. It will taken time but I am confident we'll get there to some degree soon.
As far as I could tell there is no gamma correction in the kernel because the Nexus 10 uses a new display port interface thats in the Exynos 5. Most devices I've seen have at least a static gamma table in the kernel but that doesn't appear to be true for the Nexus 10.

give him my money!
that sounds great
post in this thread if you hear more about it!
as i said in other threads i will pay around 50$ for the person that makes gamma adjustment possible for the N10.
btw: hockey puck?
are you serious ?
I do appreciate the sharper quad hd amoled on the S7e over the one on my Op3.
However, much (most) content we work with daily, especially net content is not quad hd, often not even hd.
So the phone has to perform some serious scaling.
Result; a (good) non-quad screen can actually look better/sharper.
Need proof? I also have an Elephone P9000 which IMHO happens to have one of the very best displays, LCD or not. It looks clearly better on most Web and off-line content. The difference is not subtle. That goes for sharpness and colour (despite of the S7e measuring close to perfect in SRGB. Perhaps the ability of the P9000 to display great whites as well as superb blacks has something to do with it). It uses a new LG super thin layer screen. Needs to be seen to be believed.
Samsungs amoled are very good but there is still room for improvement.
To put it into perspective though, the S7e's display is superior to the Op3's in every way.
Or maybe it's that the Elephone screen just comes closer to matching what you consider "best" in terms of color, contrast, etc., even if it's less "accurate" when measured? Sharpness on text content may have as much to do with contrast and anti-aliasing as real resolution. LG tends to apply anti-aliasing in its phones, maybe it's built in to the drivers it supplies to Elephone?
I agree that QuadHD and 4K aren't remotely necessary for most of the things we look at on a phone sized screen, but neither does the higher resolution make sharpness, color or contrast worse. The real reason for the Samsung's push to higher resolution is VR, where 2K is really inadequate, and 4K marginal.
It's a new feature in N and from what I can tell it noticeably lowers the saturation levels of the OLED to more of an LCD style. I've always preferred LCDs over AMOLEDs simply because they look more natural in color accuracy. What do you guys think and has anyone settled on one specific mode or are u switching based on the screen content?

Its not a new feature on the 6p. We've had an srgb option forever.
I personally use ex kernel and tweak saturation to around 22. The srgb mode is too desaturated on my screen.
I wonder if the shield can, through a custom kernel, adjust rgb, gamma, or color calibration. similar to a nexus 6p with a custom kernel like franco or elementalx i can adjust to a much cooler screen similar to the galaxy series.
Also I saw in the shields display settings there is a dynamic range setting which i changed to full and the screen seemed to have dramatically changed. the darks seemed much darker. i dont have an hdr tv but a sony bravia about 2 yo so i didnt think it was actually hdr but only the output from the shield.

full vs limited is in the range that the device will output colors to the screen. with limited the normal range of 0-255 values per color is limited to 16-235. (256 values per color ^3 equals 16,7million colors (3 colors: RGB)
most particularly (older) tv's won't process the full amount of 16,7m colors, in comparison to monitors which almost always do. Reason why is probably cost, to make them cheap, and to save bandwidth. So they compressed the output, losing some of the detail in between (more like MP3 in comparison to using 160kbps vs 320kbps mp3's, most people won;t notice the difference, but it is there unconsciously)
Anyway. by compressing the range, the tv then stretches these out so that those values become the new white and black. Else everything would look greyish and faded. But now you have less detail because you miss some information, because some of the gradient is missing.
Your TV is set up to the limited range, so that it stretches those to be the new black and white. But when you switch the incoming signal to the full 256 range, the tv will still stretch these as if they were the limited range, and it basically cuts off black and white information, making everything higher contrast but losing a lot of information because it's cut off. And then you'll have to set your TV to full as well, but that's not always possible. Because most tv's can't process more color information.
That's why HDR is such a big improvement, more color information, more visible dark and bright gradients and the overall brightness contrast is wider.
But I think in your case by setting it to full you will get the feeling of more contrast, but essentially you are cutting off a bunch of information. You'll probably notice in dark scenes that you can't see much, because it's clipped out.
If this makes sense to you. (I may have made some mistakes explaining this)
Regarding calibration, you should calibrate your tv in stead. There's no use in calibrating your shield. That's only necessary if you can't control your screen, which TV's can, but phones can't. So mess around with your tv color settings.
