Hi. I've got astigmatism and a high white point makes it very difficult to read on the screen. If I could describe it, the white and the black will mix together and create halos on the screen and this puts strain on my eyes. Is there anyway to reduce the white point on the pixel 3 XL? I think this will make the screen flow easier on my eyes. Thank you.

I have. I don't think they make a difference. The iPhone does have a setting to adjust the white point. I don't know if rooting and a custom kernel will enable me to do so.

There is Color Control in EX Kernel Manager. I'm not positive if it's available with the stock kernel so you might need one of the custom ones. It's under tools/color control.

Hello to all!!.. is possible to find an application to tweak the saturation of the SGS2 screen!!?... it has the worst color rendition I saw in a cellular screen, I work in photography I can not even show the pictures in my telephone!!... I like this phone but with the screen of the iphone, miles away better.
Best regards!

Thanks for your feedback, the only problem is the Saturation slider, it does not work on my SGS2 and that slider is the most important
Besides that, that application is not done in good way, the RGB sliders has to modify de levels of color not the levels of brightness as the application do.
Moving all the sliders to the left has to decrease saturation not brightness as it does in a wrong way.
Regards!
I`m disappointed too with the screen colours.If I take a picture of white walls it seems to have a white-green colour.In my old HTC HD2 with HyperDroid-CM7-2.3.7,the white was brilliant white.If I put the same picture that I taked with the HTC in my SGSII,the white looks a lot greener.Is there a fix for that problem?

The colors of SGS2 are pure crap, I dont understand why there are lot of people interested in develop a firmware but they forget this part that is really important, you pay lot of money for a phone that gives you crap colors, totally biased and has no possibility to calibrate them.
Totally agree...My old HD2 with 5MP camera takes a lot better photos than SGSII.The problem is RGB calibration of the screen,not the camera.

Yes, I refer to the color rendition of the screen.
+1 for this... couldn't find any screen tuner/gamma adjuster/saturation adjuster or whatsoever for i9100 that work in ICS...
And my screen is way too blueish... and color is washed....

The gamma should not be modified, if some app is modifying the gamma is doing the wrong thing, it should modify RGB values or saturation remaining the brightness constant.
Hmmm, i thought it was gamma thing also... since I hate the blueish tint... I prefer warmer color.... >,<

What you are looking for is the Kelvin temperature to change, changing the gamma curve will change the behavior of brightness and color and that is not the way.
The controls that should have the telephone are real RGB controls without modifying the brightness, Temperature and Saturation, even better Contrast (but it should not change the colors), with that controls you could calibrate the screen the way best fit to you.
Maybe that's the control that included in CM9...
Is there any way to change this? I mean having a white background on phone contact when dialing or when going to change some setting or whatever isn't exactly 'battery friendly'.
I remember the very old HTC UI back in the Diamond days being black, why cant we have it in black today? Or at least the option to change it to black.
If there is an obvious way to do this already then I apologize ahead.
Cheers

Didnt think of that, but still I think alot of the Sense stuff are on the One X are unecessary.
Will check it out, thanks!
white is acctualy more battery friendly on a LCD screen.
With much black you need to increase brightness to have higher contrast, making battery life worse.
What you are saying are correct - if you have a oled screen like the one on one S or sgs2. But the specific color on one x doesn't affect battery, the brightness does.
Just to share this with you guys..
With every display that I use, I try to have it calibrated and I was trilled that with the nexus I had so much control over the screen!! Never had a phone with so much control
You have here my results.
Just be aware that the "before" is with trinity kernel stock color scheme and I'm really grateful that his market tool and not to forget franco.kernel tool too,made possible for me to calibrate...
I used a 18% gray card to make sure white balance was spot on when converting the raw files into smaller jpg.
I did find that sometimes the changes did not apply so I did a double check by exaggerating the values when making the changes. Contrast was one of them..
On the graphs, the white dotted line is the reference
Only problem with this is that not all screens are the same so these settings will not work for everybody
My calibrated values
tint
red 200
green 169
blue 178
gamma
red 2
green 0
blue 0
disable dynamic contrast
contrast value 0
If you use franco.kernel tool
gamma 1.0
If you like image with more contrast, i would set it between -6 to -10
Very interesting and the before/after photos look good. Is there a problem with burn in?

Looks a little red for me. Your results look great though.
The improvement in the color of the dog photo is drastic. Trinity kernel does come with the blue really cranked up for some reason. Looking good now.

for whatever reason trinity seems to be giving me better screen color, but im sure I could do the same with franco, anyways, my gamma settings are untouched, I found that modifying the color to these values makes the purple tint go away for me:
Red:135
Green:135
Blue:190
Trinity Contrast -15 to -25
If you look at the calibrated rgb graph, red is a few points bellow reference. And again if you look at the color temperature line it is a little above 6500k. It is normal for first reaction about red when actually your missing blue because almost every screen you are used too has to much blue on it..yet again there's the tint problem on a bunch of nexus too.. if I get my hands on one of them I'll post here the results
Edit: for you "red guys" try to invert the red with blue values
Red 178
Blue 200
BUT keep gamma the same.

you're welcome.
Outstanding. I was wondering if using my colorometer would work on the phone. Looks like I have a nice project for this weekend I need to revalidate my HT and PC too so might as well throw the phone in there too :O
Use hcfr and the color swatch app from the Market..
If you get stuck on gamma, don't sweat it too much.. I spent an hour trying to get it right, no luck with this screen. Colors are bang on though.
For those who don't know, 6500k is the reference color temperature. To most people it looks too red or even yellow, but it's what the whole publishing and photography world uses.

or you can install mxplayer,
get from here:
http://www.avsforum.com/t/948496/avs-hd-709-blu-ray-mp4-calibration
the mp4 version, extract it, goto to:
ColorHCFR Fields folder,
10% Grayscale folder
and use that files with mxplayer.
My gamma is 99% spot on. I go for 2.3x since with amoled screen the black mml is almost zero, you will not sacrifice shadow content and have a great contrast
I don't get it, how you use hcfr with android? I tried but I just can test my monitor (pc) =/ is there a guide or something?
the way I do right now is testing with http://www.lagom.nl/lcd-test/ and setting manually parameters on phone until it looks great.

you don't !! you use a laptop with the colorimeter connected to it.
your phone just plays the mp4 for calibrating your screen.

Yup, just like you use it to calibrate your HT screen. I run a long usb cable to my PC and use a DVD I burned with an ISO of test screens.
Thanks for the tips on test screens for the phone. saves me the time searching them out
I was searching on web I found that I need a meter, for that is the usb port right? (like spyder2 or EyeOne) mmm I was conecting my phone XD first time trying this tools. Now I understand what all this is about.
That looks that I will be doing this as usual =/ with my only 2 eyes :cyclops: meter XDD ohh wait that's just one of them xDD
well thanks for answer and that pic looks great. Right now I'm on CM10 and config my screen with their "advance" tool and comparing to the webpage I shared. That looks good too but I perceive a little bit reddish on dark colors. Thats so F******* better than blue one XD now looks like Super Amoled plus the contrast is pretty similar to SGS3.
Great post, thank you!
Excellent information, thanks!

Has anyone figured out how to adjust the screen tone to make the screen appear less of a cool or bluish tone? Coming from another more color accurate LCD device, the blue tone instead of white bugs me.

Care to elaborate further? I just tried the different options listed under the Vision menu, none of them had any impact on the blue tinting.

Tap it and it will show a picture of jelly beans or M&Ms or something. Think of it as a grid. Center is the neutral zone.
However this will NOT change the color the white balance, only the gamma of the colors.
My LG G Tab X8.3 has a high red HUE. Comparing the G4s blueish tone against the X8.3s redish tone, is horrible. I prefer the softer bluer tones. There is an app in the Play Store to actually adjust the colors, but it is basically just an overlay. It caused me lots of lag, delay, missed touches, etc.
A custom kernel is the only way to properly adjust the LCD colors on a low level, without an app.
Actually My G4 H811 has Screen Mode hidden in settings but it does not make any effect. I wish it works on other models or at least on the rooted H815. To enable hidden feature, Need to create a Widget with Nova launcher a choose Activities. Then scroll and expand Settings and look for Screen Mode.
Gotcha thanks. I'm debating on trying this phone again, my S3 died and honestly I've had way too many uniformity and inconsistencies with AMOLED displays, so I want to stick with an IPS display. I've been using my old iP5s and I can't stand it, I need to get something ASAP. Just wish I could bring the white balance back to a neutral white, then maybe I'd be more content with the phone.
That... and better gaming performance.
I know this isn't really light bleed, given its an AMOLED screen... But when on the home screen with a black image, there is what looks like light bleed across the top of the screen. This only happens on the home screen. Any ideas?
I have the same effect up top... It's like the notification area is glowing a bit so you know it's there.

If you took a screenshot of your phone's screen and the effect is there, it means it's not your hardware. Screenshots don't actually capture what you see through the panel. Just like you can't see burn in with a screenshot you can't see light bleed or any kind of panel deformation as well.

Yes, I understand it's not hardware... But it's an issue none the less...
You can see it in the top of the image I attached in my original post. It is only persent on the home screen, and it's really annoying. It's extremely obvious with a black wallpaper.
Yeah it's that particular wallpaper of Pluto or Earth. I get the same thing. In fact, try sliding over to the left where Google news feed is and put it in between screens. You can see it sliding to the top. It's even more pronounced when you switch the display theme to daylight instead of automatic.
In other words, Google has to fix their wallpapers. Nothing to see here. It's not light bleed and I would change the title of this thread to make it less confusing.

It is not just the Google wallpapers... It is literally any wallpaper that's dark enough.
Then it's the Google launcher. The point is there is nothing wrong with the display.

I'm well aware is not my hardware. Read my original post, I clearly said I know it's not the display. Light bleed is not possible on an AMOLED screen... And also not selective to the home screen only.
Just because it's software doesn't mean it's not an issue..
It's not a bug, it's here to prevent Burn-in. It's also visible on the bottom. I saw it with a grey wallpaper, I didn't see the line of the nav bar but on the home screen I did. Like I said, it's here to prevent Burn-in.

This is correct. It is there for a reason from Google.
