[Nexus 10 Q&A, Help & Troubleshooting] pg_ice:
Hi!

im going to get the N10 in the next week and the first thing i will do because im a color junkie is a calibration test so se how close/far it is from

reference.

i have been into hardware calibration for displays for some years so i see myself as a pro.

i have X-Rite Display 3 Colorimeter and Chroma Pure calibration program.

http://www.chromapure.com/

the test patterns i use is from AVSHD709

http://www.avsforum.com/t/948496/avs-hd-709-blu-ray-mp4-calibration

i have already calibrated my LG Infinia LED TV to reference quality,so if only the right (ISF/CMS) settings is there i can calibrate any display to near reference quality.

but its all about the settings how much you can change.

so the question is:

is there a App that i can change the RGB values and saturation/hue also gamma settings?

or do i need to get a custom rom?

i know some custom roms for the SG2 has some screen/gamma adjustments in EX tweaks.

if its not i will still post the results from the calibration so you can check it out to see how good/bad calibrated the Nexus 10 is

Edit: i just found one

http://xdaforums.com/showthread.php?t=745248

but i need this for the N10

[Nexus 10 Q&A, Help & Troubleshooting] vitaminxero:
Apps on the market only apply a filter on top of the screen. You're going to want a kernel with proper color calibration support to prevent performance loss.

Here's anandtech's review of tablet displays.
[Nexus 10 Q&A, Help & Troubleshooting] pg_ice:
thanks for the link

interesting

damn the Nexus 10 is WAY off in the Gamut Chart!

how the hell can they release a screen thats is so off?

surley needs some calibration there

fix a kernel with RGB adjustments and i will fix a calibration that is better than on the iPad4.

after that you can just copy the settings and BOOM you have a reference display.

(that is if the screens dont differ to much)

i have the tools and the Knowlegde to calibrate displays but zippo knowlegde in hacking kernels

so Kernel Experts

MAKE IT HAPPEND! :)

Edit: first thing you will start with is the grayscale

when the grayscale is right (whites is white and not blue) then automatic you have your 6500k color temp (6500kelvin is messured from daylight in california if someone wants to know)

Also the Gamut is adjusted in position.

so its easy

with a correct grayscale everything (almost) else becomes right on spot.

one setting that they dont test there is Gamma

gamma at 2.2 is important if you want to see all details in darker parts of movies or photos.

gamma is adjusted with all three sliders Red/Green/Blue locked

So what i need is RGB adjustments and Saturation/HUE adjustments if its possible

comon hackers

we must beat the iPad! :)
[Nexus 10 Q&A, Help & Troubleshooting] thunderger:
If you want to have ICC support in kernel you've to ask a kernel dev. But I don't think that someone will implement this feature. Because the majority of users doesn't know or care about correct colors.

As the test results of your linked page show the N10 reaches a "good" neutral in white, gray and black. But the contrast is very low and by calibrating and profiling it you'll reduce it more. You've to calibrate D65 at 120 - 140 cd and after this to write a correction profile especially for blue and violet tones.

Apple does such things because their customers want to have and need good colors. But I don't see a market for android users. Photoshop touch is crap and there is no other "real" graphics suite / app. Given gamut is okay for daily use, e.g. viewing movies and surfing around the web.

So, don't be disappointed if your wish to cailbrate and profile the N10 won't be possible at all. An google seems not to have plans for ICC support in android, see https://groups.google.com/forum/?fromgroups=#!topic/android-developers/Ifnsdbkqxqo

The only thing that really seems off is that it has very washed out purples. Its fine other than that. It strange as it can display blue and red just fine.
[Nexus 10 Q&A, Help & Troubleshooting] AztlanUnderground:
Fortunately a lot of devs seems to think different seeing the amount of stuff they've coded that average Joe doesn't know or care about.

I for one would love to see the OP succeed as i see nothing wrong with getting better colour accuracy on my N10.
[Nexus 10 Q&A, Help & Troubleshooting] beerope:
I personally really hope that a color calibration app/kernel becomes available.....devs PLEASE make it happen!! I like the punchy (albeit 'ficticious') colors of the amoLED display on my Galaxy Note....Please devs, give us the option to control/enhance the color of the Nexus 10's screen! :D
[Nexus 10 Q&A, Help & Troubleshooting] Nuwidol:
Another shout for some calibration tools on the nexus 10. All my main displays are calibrated & it's quite a shock to pick up my nexus 10 & the see the washed out colours :(
[Nexus 10 Q&A, Help & Troubleshooting] Fidelator:
Indeed, the guy who mentioned the fact that the average Joe doesn't care about color reproduction is forgetting the fact that not a single one of us here is an average consumer, I also own an iPad 3 and I really loathe the washed out look on our display, the iPad looks very similar to the calibration I have on my Sony TV while the nexus looks almost like a color less gray when its put beside them, they all look like crap when you put them besides my SGS 2 though, all I really need to be completely happy with my Nexus would be a way to calibrate our screens, I have already pretty much given the iPad to my little sister but I hate to admit that the colors there look much much better than on the Nexus.

And by loathe I mean that I completely hate and despise it, such a great display ruined by the damn color calibration, the option should be built into Android for ****s sake.

PLEASE devs make it happen, color calibration seems to be an issue shared between all of the recent Nexus devices, for example, the screen on the Nexus 4 doesn't look as good as the one on the LG Optimus G (Or so I've read)
[Nexus 10 Q&A, Help & Troubleshooting] RoadToNever:
It's a shame Google are apathetic on this issue. Users that want do photo work are forced to go to Apple. Small OT aside: It's the same deal with audio creation apps/interfaces, Google doesn't care. I'd rather set my sites on Ubuntu.

Another vote for getting some kind of good calibration tool for the N10. I can put up with a lot, but the black levels are killing me. I would even put up with some loss of detail if I could get better black levels.

[Nexus 10 Q&A, Help & Troubleshooting] Fidelator:
Nah, the screen on the Nexus 4 doesn't look as good as the one in the Optimus G and the screen on the 7 is kind of washed out from what I've read, and from past experience I've seen that Samsung tends to calibrate their screens pretty nice, (albeit a bit saturated) on factory settings across all devices.

[Nexus 10 Q&A, Help & Troubleshooting] Straf:
It's a shame for Google not calibrating any of their screens. Nexus 4 has those ugly washed colors, same with the nexus 10. And black levels, despite as many synthetic tests you will post (anandtech etc) are quite bad.

I'm so sure this is software... and 0 upgrades from Google. Its ok they will push next version of android as soon as avaliable, but nothing else, no OTAs for bug fixing. Any other brand would have already pushed several upgrades to new devices, bugs appear and samsung, htc etc gives you solutions (not always, but...)

That app isn't able to adjust the gamma settings which is the main problem, although it would be a useful app to have.

I emailed the Dev about this & he replied (in one minute!) with this:

The Nexus 10 doesnt support the same interfaces that are present in the app, so until I manage to code something in the N10 kernel, no.

Bummer.

Don't give up hope yet! Franco has already cranked out an awesome custom kernel for the Nexus 10 so hopefully he can figure something out.

Nexus 10:

(most options depend on the kernel features, if X or Y feature isn't present in the kernel the interface in the app won't show up)

* franco.Kernel's auto-flash

* Detailed franco.Kernel changelogs

* Kernels backup/restore on the go interface

* CPU clocks interface

* Governor Control

* Color Control

wonder how many peeps that have bought his app thinking they get color control.

[Nexus 10 Q&A, Help & Troubleshooting] JupiterdroidXDA:
lollollollollol i cracked up at this;) ^^^^^^
[Nexus 10 Q&A, Help & Troubleshooting] Palmadores:
I didn't think the gamma was too far off on the N10. The greyscale is OK too. Any DE2000 score under 3 is fine, and for greyscale at least the N10 got 3.5 in the Anandtech review

However for the saturations it's way way off with a DE2000 score of 8.1 . The blue really wrong, it's half way to cyan!

So primarily it seems the N10 needs to make use of that amazing screen is a colour space tweak. I'll get mine soon and will run the measurements, but I'm prepared to be dissapointed.

As an aside, to those who say most android users don't care, there's an important principal which is often overlooked. People will use an iPad to look at photos and love it. Everything is glossy and smooth and the photos The Times newspaper app are really involving. They don't know why they are, but they just are. And it's mostly to do with having a well calibrated screen:

The human brain can perceive a poor image and see a representation of reality that we know is not real. That's the norm. However, when the screen is calibrated it's so much closer to reality that the eye is fooled into thinking it actually is real. This a like an ON/OFF switch in the brain. Either we're fooled into thinking it's real or we're not. When you change your display to enable this leap the results are really surprising. I've calibrate my Pioneer Kuro plasma and been bowled over with how involving it is now. Same for my N4.

When we think the scene is real we're sucked in and involved. You go to a good cinema (which will be calibrated very well) and you are drawn in and involved and immersed in that reality.

So people don't generally know they want a calibrated screen, but boy, they like it when they get it! So come on Google! (or Faux123 - pleeeese) let's make a display that draws people in an makes them all emotional with the Nexus10.
[Nexus 10 Q&A, Help & Troubleshooting] Fidelator:
Who is this faux123 everyone has been mentioning? And yeah, prepare to be disappointed by the color reproduction... Sadly most people don't notice it's wrong and as there isn't too many people complaining the devs don't make it a priority.

[Nexus 10 Q&A, Help & Troubleshooting] Fidelator:
Does he have a N10?
[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
Doubtful, otherwise I bet we would have seen him around these forums already.

Morific is around though, and he did some great color contrast control on the Galaxy Nexus. Before we get to things like that though we probably need to have someone find a way to gain better access to color control in the first place. Ktoonsez is probably the farthest along, and unfortunately that isnt very far yet. But at least we have some minor adjustments right now that do improve things somewhat
[Nexus 10 Q&A, Help & Troubleshooting] 12paq:
This is very true. Additionally, to touch on why Nexus devices seem bland, most companies have created their own proprietary screen calibration settings that have had a scientific true calibration and then a real world in person survey. Often they sit people down in a room and give them example to choose. The end result is often pumped up in sharpness, gamma and saturation. These manufacturers take pride in there displays and there color profiles they have created. They value these profiles as company property and they are result of much marketing research and are used to compete with other companies. Even if the displays are made in many of the same factories, the individual companies developing products can control the end user experience by developing their own proprietary display profiles to better their devices and further their product sales.

Then comes Google who ask these companies to make Nexus devices. I can only assume from personal experience, but my N7, N10 and N4 were all rather calibrated "true" or less then true compared to there manufacturer brand devices that I have owned. If you color calibrate a display scientifically or just for a good workflow for photography, it will often look flat to the average user who is conditioned to experience an engrossing display that is often pumped up a bit.

I can only assume it was very difficult for manufacturers to make competitive devices from their own factories to help Google. I am sure they all met good agreements and found good business sense to make Nexus devices for Google, but my assumptions are that Samsung and Asus held back their proprietary color profiles and just sent Google bland, flat and somewhat close to "true" or worse color profiles for Nexus Devices.

Now, this is why we root and add custom roms and kernels for devices. More importantly is to support our development community. Those guys rock.
[Nexus 10 Q&A, Help & Troubleshooting] beerope:
Correct me if I'm wrong guys......but doesn't ktoonsez kernel give you the goddamn color calibration?!?!
[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
nope it does not. No one has unlocked color calibration completely. The best we have so far is ktoonsez' kernel in that it does modify a few values that he found so give a bit better (truer) color reproduction, but it is not configurable and it is not really what we would consider true color manipulation on this device.

[Nexus 10 Q&A, Help & Troubleshooting] mrsato:
Why would he be banned? For trying like hell to get the N10 screen calibrated right?? For being a squeeky wheel? o.O

I'll go ahead and put my vote in for a kernel that allows for calibration. Not having it doesn't stop me from using and valuing my N10, but it WOULD make me LOVE it. I honestly find it hard to believe it hasn't happened yet.
[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
It hasnt happened yet because the necessary code is missing on the Nexus 10. Samsung removed the mDNIe functionality to control colors that most of their own products have. The reasoning for this is suspected to be because it is a Google brand tablet and not a Samsung brand, even if Samsung manufactures them. ALthough we have a couple small tweaks that are done now in Ktoonsez' kernel, it isnt very much. In the end someone will probably have to port over all of the mDNIe code from a Samsung device that has the same hardware as our tablet and insert it into our kernel (and possible roms). It has already been looked at for porting the code from another device, but it didnt work out. I cant remember why.

And PG was banned for his attitude towards others and causing problems between members on the forums. Being helpful by taking good measurements of the screen doesnt outweigh terrible member behavior.
[Nexus 10 Q&A, Help & Troubleshooting] 12paq:
. This ^^

EniGmA,

I have a pantone screen display calibration sensor or "hockey puck". I might consider offering to help Koontz, if he wants to get any more readings and do anymore color profile calibration of his N10 kernel. I have the time, but I just hate to bother devs when they donate so much free time for us. I'll feel it out and see what he thinks.

...and thanks for all your input on the kernel threads. I have learned a ton lurking and reading. :thumbup: :)
[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
Im glad to hear people are finding use of things that I post :)

Ktoonsez frequently sends out a test kernel to people when he is doing something new and needs feedback, I am sure that when he gets back to digging into color control again that Ktoonsez would be very happy for your help in testing of color tweaks.
