Anyone tried tweaking the white balance? - Xperia Z5 Compact Q&A, Help & Troubleshooting

It's no secret that the white balance of the screen is a but awry on our devices. The image has a bluey-purply tint to it which should be correctable with the white balance settings. I've had a go at this with limited success. Has anyone been able to get something that looks correct?

In a dutch review that was published on tweakers.net, the reviewer did the following:
Red to 183, green to 145 and blue to 0 for the best result. The screen is not perfect, but at least it's less blue.
Calibration looks like some sort of screenfilter. Luminosity and contrast suffer.
Luminosity goes from 629 to 450cd/m² and contrast from 930:1 to 650:1

Mine was reddish. So i just pumped up the green a little

I find the screen almost dead on white, pretty good really compared to the previous z1 and z3 compact.

Screen calibration. What works for you?

I have an E5506 with 5.1 root and Innolux and the screen looks a little washed out. Someone facing this same issue? What works for you?
Go to Settings, Display & White Balance.
Red 24
Green 5
Blue 49
Each person will have his own personal preference. However, after spending quite a bit of time tweaking the white balance, my best results were the ones posted above.
White levels are good, blacks and colours all look great. Give the above a try and report back.

Green tint to screen?

Not sure where to ask this, so here goes. Picked up a Z Play for my wife and it's great. Then picked up a Z for myself and while it looks and runs great, there seems to be a definite green tint to the screen when viewed off-center. And I don't mean 30-40 degrees off, but as slight as 5-10 degree off center, in any direction and it has a definite green tint, regardless of brightness setting. Previous AMOLED phones for either of us never had issues until extreme angles, and her Z Play is far better, not turning green til about 40-50 degrees, which is what I would expect.
Is this common or an issue? It's only been a few days, so I can go change it if it's a known issue of any kind. I guess I can also go compare it to display phones.
Mine doesn't appear to have this issue, perhaps a slightly noticeable change when 40° off but not at 5/10.

Me neither, nothing remarkable happening when tilting it in either direction.
When the Moto Razr XT910 was new, there were many reports of varying panel quality problems, such as strong green or yellow tints
They did get new phones when they returned them, as it was a quality issue, could be the same thing now.
If I'm not mistaken, those with lots of green had field/cloud faults when viewing a black image in a dark room at full backlight, as they failed to reach zero brightness.
It was described as the pixels leaking electrons to surrounding pixels.
Viewing angles on the Z is worse than my old Moto X 2014 for sure, but it's probably due to the smaller pixels.
Nothing beats the old HTC One M7 though, that thing never faded, but it had an IPS screen.
However, in standard colour mode, it's heavily yellowish to reddish (some would call it warm colour temp)
In dynamic it's closer to white, but with a strong nudge to the blue spectrum.
Can't wait to get the custom colour temperature setting with Android 7.0!

Contrast (true blacks)

How well do you know your fifty shades of grey? Rate this thread to express how good the Xiaomi Redmi Note 4's display contrast is. A higher rating indicates that black is true black, rather than a very dark gray.
Then, drop a comment if you have anything to add!
Contrast is decent levels.But there is a pinkish tint on my display which looks ugly
Not pinkish but a slight reddish tint but nothing major gets quickly adjusted to ur eyes
It's good, but when you are in really dark environment (like under blanket in the middle of night lol) blacks are gray.

Yep, even TN LCD's will still glow in the dark. It's because LCD displays have a backlight in the back that is always on, then the Liquid Crystals on top of that can let light through or block it. Then a polarizing filter because liquid crystals only orient light in one direction and without that you would only see white light.
And by having 3 differently colored subpixels for each pixel, colored red, green, and blue, the primary colors of light, it's able to show a couple of million of colors.
Because the liquid crystals only let light through, not produce it, the white backlight's always on. If it's always on, even when the liquid crystals are blocking all the light, some light from the backlight will come through, making the screen appear greyish or blueish, especially in a dark room.
The only modern type of display to produce true blacks is OLED. Many phones tend to have AMOLED or Super AMOLED displays which are just a type of OLED.
OLED displays have little LEDs made of organic materials that produce their own light. Because of that, if an OLED display shows something black, all the pixels will turn off and no light is produced, showing an actual black image with no glow.
OLEDs also have no ghosting, which happens in LCD's because the liquid crystals can't change their orientation immediately to display a new color.
Unfortunately, while OLEDs do sound like the better choice, they are very expensive to produce compared to LCDs and also, the blue OLED subpixels tend to lose their brightness faster than their red and green counterparts, shortening the life of the display. There are some methods to prolong their lifespan like using a 4th white subpixel, but I've only seen it on very expensive TVs.
I have my original Vita from 2012 and I can see that the blue subpixels have lost their intensity because whites look a bit yellowish now. Makes sense because a brighter green and red will make yellow.
I hope that wasn't too long but I wanted to explain about the different types of display technologies and why most screens glow in the dark instead of showing the color black
not to mention the burn in issues that amoled displays have.... thats why I prefer not so deep black over the burn in.
It's not true black for me considering Xiaomi haven't used an OLED or AMOLED display.

colour gamut and contrast?

Which setting do people use and why?
Default, it's more than good enough.
I have mine on default. I just wondered if anyone preferred the other settings
Compared to z5 the display seems a bit more on the yellow side. Ive increased the blue level.

I think increasing the blue color will damage the screen in long term use if I'm not wrong
sRGB profile is more realistic and "white color is white color". On standard color looks very pleasing but the white color is broken to kind of yellow tune. which is very visible on Settings for example.

I have read in somewhere that in IPS LCD yellowish screen work better than blue one to show black color.
maybe this is the secret behind the crisp looking screen of the XZ1 !!!!!!!!!!!!!
iPhone 4 had the same issue !
now it is Sony turn to tell us about the yellow screen ?!

I think longevity is rarly a factor when designing phones today

Question Do you have a green or grey tint on minimal brightness?

The mk III series was infamous for that.
The screen has a green tint in general, the white balance isn't perfectly D65. I still need to calibrate the white point. But there's no additional tint when I turn the brightness all the way down.
EDIT: After messing with the white balance I can see why they made the factory white balance so green. There is a serious bug and tinting the whole screen green hides the problem. Full thread detailing the problem here.
Not on mine
there's quite a difference between standard mode an creator mode. The former is more "cold" so with lower back light it looks like grey/blue but it is not a tint, just a dim colour
Pixel 4 had the green tint issue. If I recall correctly, it was related to the high refresh rate.
I do. It's super annoying. Aside from generally having a green tint, it's pretty bad at low brightness. It's very distracting
@zpk787 i had the issue, but it seems to have gone away after tweeking the white balance settings.
I have my phone set to standard mode with auto creator mode on for image quality, and then try your white balance to the attached image.

That's pretty interesting, thanks. I want to buy the 10 IV - skipped on the 10 III due to the screen issues, but there's nothing better on the market anyway and my current phone is way too old now so I'll just have to deal with it. Zenfone 9 is interesting, but it's gonna suffer from the same battery/heat issues as all sd 8 phones.
