You wanted 4.4, got the link, now asking something about v7, decide what you want before you start spamming questions.

Tap-a-talked from my Nexus 7
[Nexus 5 General] ali262883:
What's wrong with u? Stop behaving like an idiot.. I asked for 4.4 got it, i never said I don't want it.. I just asked whether it's the latest or v7 is the latest? Read before commenting
[Nexus 5 General] Tylog:
Yes, V7 is the latest
[Nexus 5 General] Luigi_2:
wait for google to drop lollipop kernel source. :eek:
[Nexus 5 General] gpvecchi:
So, now!
[Nexus 5 General] aaronsomek:
Thanks so much for this thread!
[Nexus 5 General] Hatshipuh:
Quite ironic coming from you considering your last few questions all over the forum :laugh:

On another note, stock Lollipop calibration looks a lot better or does it only appear like that due to the overall lighter hues.
[Nexus 5 General] ali262883:
Blah blah blah

Running ElementalX 2.0-test on the latest Developer's Preview and all color profiles which come with the kernel app are working perfectly! :D
[Nexus 5 General] Piereligio:
All my screen profiles are in my signature. ;)

P.S: yes, latest is v7, or better, the latest is the v7 code_blue edition, that is not available for download, but inside code_blue kernel.
[Nexus 5 General] anactoraaron:
Thanks for this thread!

Thank you so much for this! What a three day journey doing the calibration myself! I used my Colormunki Display - from what I've read the internals are the same as the Xrite Display Pro. For fun I wanted to check my calibration vs. the Xrite ColorTrue app (or should I say 'color true')

Just checking the rgb 255,255,255 (white)-

My calibration: R:435.2 G:435.5 B:436.6

ColorTrue app: R:434.8 G:418.3 B:378.7 Makes sense, using the colortrue gallery everything looks noticeably red.

Thanks again, my screen looks amazing now!
[Nexus 5 General] ali262883:
Any latest color profiles to try out?
[Nexus 5 General] fladson:
[MENTION=4809179]yorici[/MENTION] Thank you for the awesome thread :good:

I will try some later...

Do you have some gamma profiles for the new version of the Nexus Display Control?

The link with the [MENTION=1363323]vomer[/MENTION] profiles is off (http://192.227.135.147/N5_ColorProfiles)
[Nexus 5 General] Chaplan:
[MENTION=4809179]yorici[/MENTION] do you know if the lollipop stock profile is the same google used on kk?
[Nexus 5 General] yorici:
No, I'm extremely busy with my university and my job atm :/
[Nexus 5 General] yorici:
If I find time tomorrow, I'll have a look at it. Thz for the link update btw

Edit: The Nexus Display Control app seems to work properly? If your question is whether I have new profiles, then I'm sorry to inform you that I'm currently very busy with my university and my work.
[Nexus 5 General] yorici:
Seems unlikely to me. I haven't noticed any difference, but I also haven't tested for it either. With the new Nexus 6 and Android Lollipop, it would not be in Googles interest to tweak the display a little bit for the few users that actually notice and care. But we will see it immediately when profile support is implemented.

Edit: Checked - Nothing new
[Nexus 5 General] yorici:
You may want to share this profile with the people:) I think some of them surely want to try your version out!
[Nexus 5 General] anactoraaron:
Since updating to lollipop the free faux app in the op no longer works. I also don't know how to create a profile as that app doesn't seem to have that functionality.

I'm just going to post screenshots with the relevant info and if someone can work this into a profile I would appreciate it. I've been trying to make this into a profile for a few weeks now and can't seem to find a way to translate these numbers into another app to do so.

One thing I noticed when getting to the darker values is once it got to a certain point to match the spreadsheet as closely as possible the value needed to be 1, and even then it was very slightly bright (not significantly so).

White point was 28.
[Nexus 5 General] anactoraaron:
EDIT : I should also mention that I was shooting for perfect 2.2 with as close to perfect blacks as I could get. Throughout the spreadsheet my first 10 recorded values in HCFR were all within 1 (sometimes nearly spot on) and even the 20-24 were within .01 to .02 (sometimes I couldn't get closer as I was already at 1 in the gamma app).

Also for the gamma app the first 12 values work in reverse (raising the values lowers) and the last 12 values work 'as they should' with lower numbers lowering.

EDIT 2: Decided it was worth the 1.99 to get my calibration back. I'll post my profile soon.

EDIT 3: Here's my profile. Had to flash back to stock for my old neg values as the default neg values are different in 5.0. Hope the zip file works as xda won't let me upload the profile as is.

EDIT 4: This is just getting silly lol. For whatever reason the profile wouldn't save so I tried manually adding the numbers in the file and got blue and red mixed up. Fixing now and will upload when fixed.

EDIT 5: (Last one I promise) - Profile fixed and uploaded. Enjoy!
[Nexus 5 General] yorici:
You need to flash a kernel that supports this like Franco kernel (if didn't figure this out already;)
[Nexus 5 General] yorici:
I looked at your profile;)

The reason for the 1's at the end is because you had chosen a white point of 28. White point 28 is quite dark and the 1 actually means 255, like you noticed. So you hit a limit indeed as 255 is the maximum.

My question to you is: why did you choose wp 28? ;)
[Nexus 5 General] anactoraaron:
I thought it would help me get black as dark as possible. I picked that first before calibrating, and didn't realize that I would 'hit a wall' by the end. Even so, I'm still generally pleased with how it turned out the first time around (the values in the spreadsheet are very close), and if I get some time to do it again I will pick a white point of 32 (or maybe higher, who knows?)

Time is my only enemy this time of year, I'm just really busy with work.

When I do another calibration I'll post the profile here of course :)
[Nexus 5 General] yorici:
Best results are achieved with whitepoint 31:)
[Nexus 5 General] anactoraaron:
Ok so I was messing around tonight and I don't think white point 31 is for me (for my display anyway). I'm at value 17 and have my blue pos at 1 and I can't make it any closer than .3 (it should be at 2.375 but the darkest I can get is 2.615) without adjusting the blue neg (which I didn't really need to do the first time around). I can get it spot on, but from 17 on I need to adjust the neg as the pos is at 1 for red, green, and blue.

At white point 28 I still had some wiggle room at value 17. Personally I can't see much difference between 28 and 31. I'm going to keep tinkering :D

When I'm done with white point 31 I'll post a profile. Any suggestions for my next run?
[Nexus 5 General] yorici:
To me that sounds like a limit of your display. Maybe you should check extreme white points like 0 and 63 to see if you can change value 17 - 23 at all, before wasting time on those values. After that, I would check what white point gets you the best contrast and brightness combination. For me that was wp 31. I checked on value 1 (RGB 255, 255, 255) for several white points (28-34). Then calibrate normally.

Try to not have values 17 - 23 the same value. Doing this will make blacks appear the same color. So you can't really see shades.

Also: I usually keep pos and neg the same unless I really need to. Otherwise it's kinda hard to keep track of change and when making adjustments.
[Nexus 5 General] Mythos123:
hi guys

out of curiosity, which color profile do you use atm?

I have been using Yorici's punchy one for quite some time and loving it!

Nexus 5 & Tapatalk.
[Nexus 5 General] Tzfardaya:
Mag01 or fluid v4 usually...
[Nexus 5 General] yorici:
I think I found something like that too one time. I edited all values to 0 and found that there were two parts. One part being a constant rising line and one part being constant.

About the changing values; Do you measure the first value every time before measuring any other value? Because it depends where you measure on your screen. To counter that, I created the procedure that uses a ratio of first value : other value. So you have to change the value of the first value everytime in the spreadsheet to get the right value for 'other value'. It works like a ratio and the ratio is independant of first value (I assumed).

Very nice profile, will use for some time now, thank you.
[Nexus 5 General] electronicmaji:
Guys I was hoping you could help me. My friend recently purchased a Moto G 2. I became quite jealous very quickly of the very nice screen. I was surprised by it it looked clear and clean. I looked up the stats and to my surprise the technology of the screen was the same and the resolution was lower. So I asked my friend to compare my Nexus 5 screen next to his Moto G 2 screen. It was like night and day. Despite the lower resolution (which is noticeable but not nearly as noticeable as the next thing) the Moto G 2 has a much clearer image. Whites on the Nexus 5 have a very yellow tint. On the Moto G 2 they are as white as white can possibly be. The colors are more vivid too. Is there anyway I can get a Motorola Color Profile on my Nexus 5? Or is the Nexus 5 just made with a inferior screen?
[Nexus 5 General] Tzfardaya:
Contrary to popular (your) belief, the n5 is actually the better calibrated of the two... If you take a picture of a solid color then compare the picture displayed by both phones to the original, the n5 will be closer.. It's calibrated quite close to the sRGB standard, whereas most phones, tablets, TV's, monitors, and other displayed are calibrated for that fake saturation "punch" that people have been conditioned to think is right...

But, depending on what kernel you have installed, there are various community created calibrations that you may prefer..
[Nexus 5 General] Mythos123:
this was asked in the main thread of Franco kernel updater as well by another xda member...

anyone know, where to put the colour profiles in for new FKU (material design), i have put them in the color_profiles folder in franco_kernel folder in sdcard but its not showing up in the profile list in the app. txt extension is removed.

[Nexus 5 General] Thepho3nix:
Hi community! I'd like to set my panel in my nexus and tweak it a bit and look like an iPhone IPS panel. So i can achieve darker blacks and natural richer tones without a hype of saturation like Samsung. Any way or setting I can do this? Thank I'm advance guys.
[Nexus 5 General] Tzfardaya:
Buy a colorimeter and get to work. ;)
[Nexus 5 General] Thepho3nix:

Any settings to share ? Thanks :D
[Nexus 5 General] Tzfardaya:
That's only half the equation...you want a specific result, you need to be able to test your progress... That's where the colorimeter comes into play..
[Nexus 5 General] Thepho3nix:
I got your idea...

I meant maybe there's a setting shared in the past here in this thread in could be useful to me. Don't miss understand my request, I said iPhone look, because apple take advantage of IPS display, and for me its perfect. Thank you bro.
[Nexus 5 General] mrvtec69:
try yorics Punch profile, it should do what your asking for
[Nexus 5 General] TheForumTroll:
Holy crap this is confusing! Coming from calibrating with two numbers per colour (TVs etc.) to this is.... well let's just say I have no idea what I'm doing. I have hardware to profile displays and do so on everything I can come near but my phone is totally off. The profiles I've tried are wayy off for my display :eek:
[Nexus 5 General] yorici:

Reccomended values on code_blue, use kernel adiutor.

Go in screen tab, values to change are:

Screen value 132

Screen contrast 125

Screen hue 1534

Saturation 43

Bold values are only to set if you use stock code_blue profile, that is my TrueRGB, only a little bit tweaked.
[Nexus 5 General] yorici:
Tried them out. I then proceeded to talk to Savoca. They are interesting settings, but there are some more that need to be tested. I don't have time to measure anything, but in a week I might have;)
[Nexus 5 General] tanjiajun_34:
Sorry guys I totally know nothing about all those screen colour settings. All I know is how to download and load up profiles... :X

Anyway I have some questions

1. Is a colorimeter like dumb proof? I mean like for someone like me who have totally no experience will it be a total waste of money?

2. What is the difference between the new kcal and the existing colour controls?
[Nexus 5 General] yorici:
1. You should ask yourself if a nicer screen is worth your money. For pc's it's a breeze to setup (install software and follow instructions), for Nexus 5 it's actually quite a bit more complicated and it takes much more time. Tv i dont know.

2. New kcal are just a bunch of variables that can be applied to every qualcomm device. They are interested, but not fit to calibrate the screen in great precision. However, they are fit to make minor adjustments.

The values talked about in this thread are Nexus 5 only and are more precise.

(Note: There are more kcal functions to be discovered, so maybe the kcal is more fit for calibration in the future)

Sorry for the mess can't put pics on edits for some reason. These are from elemental X kernel app

It's by far the best way to set colors. There are tons more profiles. A good way to get color cards free. Go into the kitchen. A lot of color boxes have a reference colors section on a flap on the top or bottom with a wide selection of perfect colors.

Is anyone capable of reproduce dirty unicorns' color calibration? I think it seems almost perfect and would happy to replicate on stock rom.

Thank you.
[Nexus 5 General] Laggalot:
Well it might be kernel side so try and check with either FKU or ElementalX app which profile is being used right now. If not I have no idea since I havent used the rom yet... you can always ask the devs...
[Nexus 5 General] Tzfardaya:
Iirc the dirty unicorn color is a very cold set.. From when the devs were just starting to work out the colour system used on the n5... And the variable they were changing controlled the timing... All the devs except one decided *not* to change that particular variable... And no one that I know of has managed to reproduce that same colour shift.
[Nexus 5 General] Laggalot:
2 cold profiles I can think of are Pierelegio v7 and yori ;) but i guess thats not much help to you ...
[Nexus 5 General] Tzfardaya:
I use D65 calibrated... Or as close as I can get with my colorimeter
[Nexus 5 General] RoadToNever:
Would you mid sharing your settings?
[Nexus 5 General] Tzfardaya:
Heh, if I can track them down, I haven't used my n5 as a daily driver for a while now... Yorici has a pretty close set posted in this thread somewhere...
[Nexus 5 General] RoadToNever:
I'm using Yorici's right now. There was one other user that shared D65 settings. I'd enjoy comparing with yours when you are able to share them.
[Nexus 5 General] Tzfardaya:
Yorici's are pretty much the same as mine, as we were swapping the file back and forth to see how the different devices and colorimeters reacted to the calibration... We have different brand colorimeters. I think towards the end I was just being lazy and sending him the results from my testing and letting him tweak... :P
[Nexus 5 General] Sott:
So it isn't possibile to reproduce dirty's colors, is it?

Thanks for answering, btw. I'll stay with pierelegio v7, but I think the white is maybe too cold and '"bluish"... Maybe tweaking with rgb settings I can try to reduce this perception.

If it's the one I'm thinking of, no.. But I might be wrong.

Hi [MENTION=4809179]yorici[/MENTION] and [MENTION=4860519]Tzfardaya[/MENTION]!

Maybe it's not the right thread since I've got a question about KCAL but you two are very fond of color calibration theory soooo :P

I'm on Lollipop 5.1.1 with a kernel that fully supports Kcal. 'm using the app in this thread to calibrate my colors http://xdaforums.com/android/software-hacking/dev-kcal-advanced-color-control-t3032080.

Besides the RGB sliders there are also saturation, value, contrast and hue sliders.

I calibrated the RGB sliders to achieve perfect white using the 255,255,255 picture, but now I don't know how to proceed for the other sliders :(

Owning a colorimeter what's the process to correctly calibrate the other sliders? Thank you very much :)
[Nexus 5 General] Tzfardaya:
Pretty much yes... Even getting the white "right" requires a colorimeter/spectrometer... Because each colourspace uses a different shade of white depending on the temperature of the colours.
[Nexus 5 General] yorici:
All the sliders you mentioned don't work for specific RGB values. They affect the entire range. That's the problem you will face. If you improve A, you will deteriorate B.
[Nexus 5 General] Jeeza:
Thank you both! So you're saying there isn't a correct process to calibrate correctly each slider, right? If I calibrate correctly the contrast, white point will be off?

What would be the process to calibrate contrast? Reading with the colorimeter a certain shade of gray and tune accordingly?
[Nexus 5 General] RoadToNever:

[Nexus 5 General] franciscofranco:
Great write-up, I learned a lot! :)
[Nexus 5 General] nihil0:
Hi,

I am the developer of the Display Tester app and I would like to set a few things right, because I think, the author of the first post made some mistakes:

1.) First of all, the app uses a grid with 0 and 255 colour values. It is sure, because I wrote the software.

2.) The formula "50% gray = 0.5^2.2 * 255 = 186 " is not correct. It is "0.5 ^ (1/2.2) * 255"

3.) In the last release I added the 25% and the 75% gamma pictures besides the already existing 50% gray gamma picture. I hope, this way a better decision about the quality of the gamma correction will be possible (but still not a calibration quality!).

4.) The app was newer designed for calibration. The app is a set of quick tests to gain enough information about the quality of the display.

5.) When you would like to improve the app and the quality of the tests, please join the Display Tester beta testing community and discuss your ideas there.
