Hmmm 12 registers not 9? Isn't it Gamma Gradient midpoint, lower and upper?

Also, aren't the values hardcoded into Franco's kernel?
[Nexus 4 General] lowtje:
Same here!
[Nexus 4 General] xdaShex:
what app are did you use to adjust the grays, mids, Saturation etc ?

By the way. Will changing the gamma on the Franko kernel updater burn your display? I saw a warning by Moles about changing the values.
[Nexus 4 General] malavi:
After all day "testin" I see whites a lil bit rose... so changed to:

RGB (LG): 255,250,245

GAMMA0: 15,15,5

GAMMA1: 0,0,0

GREYS&Grad: Google stock / untouched

VIbrant colors, good whites, and bright (@ 50-60% brightness) :good:

What do you think? :confused:
[Nexus 4 General] sarkozy:
I found a "translation" of the Halfbreed settings to use with Faux' App. The colors looked entirely too dark on my device though, even at max brightness. Played around and came up with this which looks VERY similar to my old SGS AMOLED screen minus some of the saturation. I'm using the "stock, enhanced" 4.2.2 kernel. The original converted values are in parenthesis.

RGB: 255 250 250 (255 255 255)

Yup, you're right. Really need more time off.

About them being hard coded in franco (I didn't look at his kernel long enough), then yes you can convert them to faux's but not vice versa, if a set of values has these 9 values differently.

On LG Presets for now.
[Nexus 4 General] Girn:
Seems I can get red green blue both to 2.0 but yellow and cyan stick around 2.6.. But the side effect is grey becomes totally out of whack.. Makes everything so dark so much contrast.. Wish there was more gamma settings
[Nexus 4 General] undercover:
That's pretty extreme. What are your settings?
[Nexus 4 General] AppReviewBros:
Using Amp0: 23/22/22 for now. All colors seem to be between 2.1 and 2.5, however, like Girn says, grey becomes out of whack.

I have been messing with the settings for like an hour and it is not fun at all!
[Nexus 4 General] undercover:
Yup. Mine are fairly close to yours. Grey is out of whack (just more contrast which I don't mind at all, especially if brightness is up from the lowest) , but I can live with it as long as other colours are more or less balanced. Mine are between 2.2 and 2.4.
[Nexus 4 General] Sebacestmoi:
I have tried your settings and all I can say is it looks wonderful!

I just want to know how you know that the gamma are 2.2?

You use a screen calibrator? How do you use it with your phone?

Why is it when I just opened up the spreadsheet for the first time it said a completely inappropriate racial remark?
[Nexus 4 General] kwerdenker:
Because some a**hole seems to have deleted all the information and put that stuff in. What is it with people these days.

Probably not a good idea to have a completely open spreadsheet that anyone can edit.

[edit: I have reset the spreadsheet to the last usable state I could find in the history. hopefully who ever edited is not coming back until someone can lock this down]

[edit 2: whoever it is, he/she/it has way to much fun editing the spreadsheet. no point in trying to reset it.]

[edit 3: i made a clean copy of the spreadsheet and locked it. for those of you who only want to see the values, you can see the racial slur free version here. will take this down as soon as the op has restored and locked his version.]

Thanks for doing this. What kind of loser a- hole does this kind of stuff? I mean seriously, get a life
[Nexus 4 General] kwerdenker:
No problem. Can't have that kind of behavior ruin a good effort. Probably just some bored kid who didn't get his daily troll fix on 4chan or whatever. At least it seems the troll is back under his bridge for now.

When you do have your sheet in order, just post here or send me a pm and I will remove my links so there is only one version of this with the guaranteed newest values.

Btw: really love the work here. The colors do look a lot better with the settings found by the people in this thread :good:

Never used trinity kernel before. Hehe. Hope someone can take a peek on what settings are Google preset on it.

You can't use these settings with franco's kernel. These are only for faux' kernel and his app 'Nexus 4 Advanced Gamma Control'.

But still you will find the halfbreed settings for franco over here. Just click gamma on the bottom

[Nexus 4 General] resynx:
Thank you much for translating these! :highfive:

Added :good:

Edit: Everyone I highly recommend trying the latest line, #38, in the Gamma sheet. These settings look absolutely gorgeous and the colors are practically glowing off the screen for me! ^_^
[Nexus 4 General] DirkBelig:
Something must be radically off with faux123's screen because the settings on line #4 of the Grey/Gradient tab look sickly, dark and return RGB gammas in the 1.8-2.0 range, so his comment of almost all being 2.2 doesn't match what I'm seeing. His "vivid" colors on line #3 are certainly vivid, but wildly inaccurate and unusable. :eek:

The best settings seem to be line #3, the "LG Presets", though when you load the actual LG Presets from the app's button, the RGB and Gamma Amp 0 and 1 settings don't load. Also, hitting the backup button gets a "backup failed!" toast and trying restore gives an error about no backup existing.

While it's great to have an app that allows us to really dig in, the spreadsheet is starting to get useless because it's all just personal preferences on top of wildly different screens with different color casts. I tried one user set and it could be best summed up as "turn everything up to full" with all 255s, 31s, and 7s.

I requested a guide as to what settings did what and all I saw was that block chart showing what modules fed what. I was hoping for something more practical like, "Increasing the value of the Grad Mid Point does [this], reducing it does [that]." Also, is it really too hard to make keyboard entry of values work? As brilliant a hacker as faux is, I can't believe there's a technical obstacle to make the fields work with the keyboard.
[Nexus 4 General] resynx:
Everything is personal preference, it's a dev forum. We all come here to choose what we like and set things up to our preference. Having a bunch of different screen calibration settings available to you to use is far from useless. And just because you found some settings you didn't like doesn't mean everything is useless. I for one have gotten some beautiful settings because of everyone's contribution to the spreadsheet.
[Nexus 4 General] faux123:
Update your app :D

If you CONTINUE to have issues with the latest version's backup / restore, update your busybox too :D
[Nexus 4 General] copi:
because using motley since his kernel contain both faux n franco color, when turn recommended color setting on franco app, it come out value in faux like this :

rgb 255

amp 0 : 23,23,23

amp 1 : 0,0,0

gr : 000, 444, 777, 777, 666, 777

gr : 000, 000, 777, 777, 111, 777, 666

when in franco app using this ( i think its obsanity value ) :

rgb 255

grey : 0

mid : 119

black : 119

contrast : 23

brightness : 0

saturation : 119

white : 103

then I flash faux kernel again and try this color setting with faux app,, it come up the same like those franco recommended setting hehe :D

edit :

1 more..

on franco app using ceejay83 setting (2.2 gamma)

rgb 255

grey : 0

mid : 103

black : 119

contrast : 0

brightness : 6

saturation : 71

white : 3

transform to faux gamma setting become :

amp1 : 6,6,6

gr : 000, 444, 777, 666, 666, 777

I showed my screen to two friends, (both being iPhone users). They were stunned by what they saw. One described it as,

'Looking at something that doesn't feel like a screen, but instead a photo caught between a frame; being the bezel.'

I agree with this statement. The colours make me feel so glad to use my N4.

Black are deep.

Images are sharp.

Colours are vivid.

Whites are bursting (which allows me to use my device at 20% brightness in most environments without underwhelming visuals.)

The balancing isn't professionally measured, but it did take me a good 2 hours of trial and error to finalize them.

If only one other person benefits from this post. I'm a happy man.

I'm stoked to share them!

Perfect *Almost 2.2 Gamma Settings

We all know that most devices should be calibrated to the 2.2 gamma range for ideal contrast / color. So, I have played extensively with the settings here, borrowing from Paranoid Android presets, and specifically sarkozy's tweaks a few posts up, and adding in my own, I have come to what I think is very close to the perfect 2.2 Range Gamma Settings for our device. It is very hard to keep the greyscale Gamma settings in check while still getting accurate color gammas. I have gotten as close as possible to a balance of around 2.2 in every single gamma category as I think I can get.

Here are the settings:

RGB: 255 250 255

GAMMA AMP 0: 18 18 18

GAMMA AMP 1: 8 8 8

GRAY 08-15: 0 0 0

GRAY 16-23: 4 4 4

GRAY 24-31: 4 4 4

GRAY 32-39: 4 4 4

GRAY 40-47: 6 6 6

GRAY 48-55: 7 7 7

GRAD LOWER: 0 0 0

GRAD UPPER: 0 0 0

TOP HALF 1: 3 2 3

TOP HALF 2: 5 5 5

MID POINT: 2 3 2

BOTTOM HALF 1: 0 0 0

BOTTOM HALF 2: 3 4 5

These settings net me:

Grey 2.4 / Red 2.2 / Green 2.0 / Blue 2.1 / Yellow 2.2/ Cyan 2.1 / Magenta 2.2

These values give really nice whites, good contrast in the greyspace and a very balanced color pallete (exactly what you should expect of a calibrated screen @ 2.2)

These settings are great for those who want accurate colors, but might not be for people who prefer darker and "moody" calibrated screens.

For comparison, paranoid android (contrast) gives:

Grey 2.8 / Red 2.1 / Green 2.1 / Blue 2.1 / Yellow 2.6 / Cyan 2.4 / Magenta 2.1

also for comparison; the Faux values using the 178 staring point for the RGB gives:

Grey 2.4 / Red 2.0 / Green 2.1 / Blue 2.0 / Yellow 2.4 / Cyan 2.3 / Magenta 1.8

[Nexus 4 General] faux123:
Don't worry about the names (BTW, those names are huge misnomers :( the gamma settings aren't named like those in hardware and don't behave as their names described). FauxDisplay has all 27 options open and allows for true independent adjustments. Just look up the tab for gray/gradient in the color spreadsheet and you will find all the settings you need.

[Nexus 4 General] cygnus56:
Yesterday I had the opportunity to compare the display of N4 vs HTC One X (for many the best display of 2012) and if indeed the HTC One X has the best display of 2012.

The truth is that the viewing angles are excellent X One where you see them (although for many it does not matter, ultimately means a superiority on the screen).

As for colors maybe all it would do to improve N4 screen would have a warmer color (something that can be achieved with calibration), but is that the colors of the N4 are cold so to speak but I have calibrated values that makes vivid the colors, the screen continues to be in cool tones, and One X has warmer colors.

I like to think that if this is the X One can not imagine the quality of the new HTC Screen One

Anyone who has compared these two devices have some gamma values ​​to be approached to One X?

from the display app or trickster mod, matching your setting with the Google or LG presets.

i noticed there are colors difference between stock 4.2.2 kernel and stock aosp 4.2.2 kernel. don't know whether google did improve color calibration on 4.2.2 factory image.

but if you're on stock rom then it must has been on Google preset by default.
