Display Calibration - One (M9) Q&A, Help & Troubleshooting

With root/boot unlock in mind, once achieved will the display be tweakable at all? I like everything about the m9 upgrade except for the display. The m8 is much, and noticeably better in my opinion. Thoughts?

Totally agree.
I have found two problems here:
1) Automatic bright level is too low, even setting it at maximum level.
2) Screen looks greenish, colors are dark, M8's vibrant colors are not there. Panel seems to be manufactured by another supplier. It seems cheaper than M8's. I am looking forward to a custom kernel to alleviate the damage.

Color Calibration?

Have had this phone for a few days and am adjusting to LCD again after a long stint with SAMOLED+.
The colors on the Optimus look a bit muted to me, and dark grays aren't quite as deep as I prefer them. No doubt I'm just used to OLED. Is there a way to calibrate/adjust the color or even the gamma level? I don't know of an app that does it. Some ROMs have this feature.
Also, anyone know what the color gamut on this LG is? I hope that it's not low color gamut like the iP4, but it doesn't appear to be (hard to say, different OS).
I'm the only one who wants to color calibrate his display?
Is there a script available similar to this for the Galaxy Nexus? http://forum.xda-developers.com/showthread.php?t=1521195
Even pentile matrix users want a color calibrated display!
I obviously can't speak for all users, but I've been completely happy with the color reproduction of the Nitro display. In fact, I'd say this is the best display I've ever used on a mobile phone. AMOLED's tend to be over saturated according to the experts whereas this screen scores really high in all tests of quality. Minus the HTC One X, we probably have the best display out there.
Out of the box, SAMOLED+ displays are horribly inaccurate and far too sharp, but after calibration (especially under 4.0+), colors can look quite accurate yet pleasing.
I'm not expecting this IPS display or any LCD to match OLED for black levels, but I believe that the Optimus' display, with some minor tweaking, can be better than it is right now. On LCDs, I prefer to turn up the backlight, turn down brightness, crank up contrast, and lower gamma: this creates very deep blacks and amazing contrast. Dark greys and minor details are slightly crushed, but this is a compromise that I'm willing to make.
Is there a script to lower the gamma level on the Optimus? I don't even need to do anything with the colors, though of course proper calibration would be nice too.

Washed out colors?

If I go to Display Settings -> Screen Mode and select "basic" all the colors show like pale or washed out (see attached screenshot). Is that normal?
Until now I had that setting on Adaptive, in which case colors look "normal". What is weird to me is that selecting "basic" makes them look so bad, I would assume that in basic mode they would look fine, without any kind of processing, but still like they would look with any other phone.
Is this normal?
Basic is very accurate. Give your eyes a few hours to adjust and then adaptive will look way too intense.
As dlongb13 said, Basic is actually more true to life coloring. Adaptive is more saturated. Checkout Display mate for more info: http://www.displaymate.com/Galaxy_Note4_ShootOut_1.htm
One of these modes makes your display look like a crappy LCD. I think that was the Basic or AMOLED Photo Mode. I've seen this on both AT&T and T-Mobile Variants, so definitely go with Adaptive Display (unlocks the full potential of AMOLED)
If you are used to overasaturation the basic mode may feel a bit bland but based on calibrations it is the most accurate mode and one of the few displays capable of reproducing such accurate colors.
Many manufacturers torch/oversaturate their displays to make them stand out initially aka. Sales mode.
That is the default on our phones as well it's called adaptive mode.
If that is your cup of tea feel free to use it no one is stopping you.
old lcds were striving for accurate colors their only issue was black levels.
There could be a long discussion about what "accurate colors" are, but that's not the point of this thread.
Here's the thing that still bugs me: in order to see the "nice" colors (satured) we need to use the Adaptative mide (the default one). According to the article that someone posted, that mode uses some real time processing to calculate what colors to show. Does that mean that using that mode requires more battery (more processing) than the default mode? Does that mean that to get "nice colors" (the ones you would expect to see instead of the washed out ones) you need to sacrifice battery?
I would imagine it uses more battery.
Switched to basic 3 days AGO. now it looks perfect to me and adaptive is too harsh IMHO

Nexus 5X Screen/Dull Colors

Hello everyone. I am planing to upgrade to a new phone, probably the N5X, but the problem is I can not test one myself. I have watched several reviews and on each one of them I noticed that the screen has dull colors, even when compared to the sony z3. Colors look washed out, with a yellowish tint. This is the only thing keeping me away from buying this phone. Is it as bad as it seems ? Did any of you notice this the moment you started using your N5X ? Any feedback is appreciated. :highfive:
I haven't really found the colors dull. The contrast and saturation is not good as the AMOLED on my Samsung but it wasn't annoyingly so.
It is a warmer display but the Mar or Apr update added a setting to use cooler calibration, which makes it comparable to other "cool" displays. I actually don't turn on that setting because it makes the display too white (for my liking) but it is mostly a matter of what your eyes get used to. Many people find the cooler setting to be preferable.

Actually, barring any weird manufacturing issues, the N5X has one of the most accurately calibrated displays right out of the box. The colors might seem dull when compared to an AMOLED or the Triluminous display on your Z3, but they're accurate, not oversaturated. People tend to like saturated and vivid color. ****, I like the saturated color on my Sony 4K TV (uses a similar "Triluminous" color gamut that your current phone uses). I calibrated it one day and hated the color and lack of overall "pop".
Luckily, if you do pull the trigger on an N5X, you can tweak the color settings on your screen to your heart's content using a custom kernel (which you should absolutely have considering it's a Nexus phone) and kernel manager app.

I've used color calibration for my m8 before, but when I went ahead and tried to calibrate the n5x display to my liking, I kept coming back close to the default settings.
Haven't used amoled phones in a while but I'm happy with the screen so far, left all calibrations to default.

Washed out Screen Issue

Did some comparisons between the Moto G5 plus and my old ASUS Zenfone 2. As soon as I started using it the colors seemed off, everything had this weird olive greenish hue and It didn't make any sense because launcher/homes seemed fine. But I'd browse a website, play pokemon go, or look at instagram and things were just washed out and dull while at the same time parts looked fine.
Finally found a test that explains what I was seeing and it's not good news. I was running the latest firmware with the volte fix. The app i used is called "DIsplay Tester" by "Brainntrapp" and open the test was "Banding, Contrast, Saturation" test. There are so many colors just missing on the G5 Plus the gradient looks horrible. The banding you see on the G5 plus was not visible in real life but the missing colors and hardness of the gradient was. Photos were taken with a Nikon D90 and Tamron 17-50 2.8.
The screen was driving me nuts so I didn't mess around with getting a replacement or sending to Moto to fix because I couldn't live with it if it didn't get resolved. I'll just have to keep looking/waiting for a replacement to my old zenfone.
Figured if any of you were having issues you could see if yours is similar, also curious to hear if you're _not_ having this issue as well which means it may make sense to buy once production issues are fixed.
I can't really tell any difference between Vibrant and Standard, but don't see any banding as in yours and think they look pretty decent imo.
The screen is on the less vibrant side than some others, but colors appear very accurate/realistic and the sharpness of detail is very good. My Moto X Pure screen is 1440p with more color depth but it has a yellowish tint to the whites in comparison. Coming from the Pure at first I thought the G5+ screen was going to be too bland, but after using it awhile I like its softer look which seems easier on the old eyes while still being very viewable.
I agree there's a really minimal difference between vibrant and standard. However, you took screenshots which will not show any issues as the actual data being sent is correct so we can't know if your screen does or doesn't have this issue. I had to take a picture of the screen with my DSLR and included my ASUS for comparison as a way to demonstrate the issue.
In the pictures I took, the hard breaks you see between the colors in the G5 are supposed to be smooth gradients and there is a ton of blue missing from the panel as well. This isn't just an issue of the screen being generally desaturated this is an uneven distribution of missing/desaturated colors. If it doesn't bother you that's certainly fine but it's very much an issue with the screen that should be addressed as it means that it is incapable of accurately reproducing colors even if the reproduction is pleasing to some. The banding I'm referring to is in the green section on my pictures and was not visible in real life and some form of artifact from taking the photo.
Sorry, I misread and thought you were referring to the banding as the main issue. I do see the more distinct color separation or breaks when looking at it directly in the app in either color mode. Just ran Display Tester on my Moto X Pure which shows the much more gradual blending (like on your ASUS) when looking at both phones side by side, although it should costing $150 more.
So it does indicate the G5+ lacks in color depth, something I noticed right away but which hasn't seemed like a minus after using it. The sharpness and wide viewing angles still seem like good quality, perhaps because it's IPS. But now I'm wondering if the KCAL features included in the latest extended stock kernel might help adjust things to look better.

That's part of why this confuses me so much. The sharpness and viewing angles are amazing for an IPS panel I'm not sure if IPS has anything to do with the colors (the ASUS is also IPS). I'd be very curious if KCAL helps as it seems like it should be able to, it could also be as simple as a bad color mode on the panel driver? I'd love to see a comparison from a custom rom to stock. I'm very split on thinking it's a software issue or it's a hardware issue. I don't have enough knowledge or experience to really do anything useful, but I'm hoping that providing the info gives others an ability/info to understand and look into it.
KCAL greatly improves the 'banding, contrast, saturation' result in Display Tester, which now looks as good as your ASUS or my MXPE once I found a good range of settings. Even on KCAL's initial settings the color gradients looked drastically better, so whatever was causing the lousy color depth definitely seems to be corrected by it as the screen looks excellent now.
I'm running on stock using the extended kernel btw. Maybe someone using a custom ROM can post on whether the colors are noticeably better than on stock and also test it in DT for comparison. Seems it'd be more of a driver or configuration error or bug than something hardware related, so maybe Lenovorola will be able to fix it with an update.

How can I activate srgb mode on Moto G5 Plus

What we have to help with the washed-out screen is KCAL support available in both custom kernels (ElementalX and Extended Stock) on this forum. After installing either kernel you'll need to use either EX Kernel Manager app or Kernel Adiutor app (both at Playstore) to access the color control settings. I also found the Display Tester app mentioned above useful for checking how the settings I made looked. My screen looks terrific now.
I found that setting Saturation to 45 brings the best improvement, while setting Value to 135 brings another slight improvement.

I tried that and looks pretty good. Going to tweak contrast and see too. We should start a thread sharing tweaks
There is no way to fix this without root or Custom Kernel?
So if I'm getting it right I have to run kcal v1.2 on my moto g5 plus and from there I have access to color controls, is that correct?
Unfortunately, I have this same issue, although I didn't realize it, because my wife used the phone on the wifi to talk on Facebook so I ran out of time to return it.
What makes it worse is that it's the amazon-ads version so I can't even root it.
I put this phone right next to 3 other phones (with all LCD screens to be fair) and the difference is kinda shocking. The G5plus looks like it's been bleached, all the colors are faded, like I pulled some sliders to make it less vibrant and more black/white.
My wife didn't notice it, since she was using a basic phone until she got herself a new phone and told me, that "how come this looks more colorful?" That's when I took a better look at the G5plus.
After using it as my daily driver for a week, this phone got some serious color issues. Interestingly the pictures I took looked awful on this phone, but when I looked at the same pics (uploaded to google photos) on my PC, they look ok, not missing any colors.
Another issue I noticed. I turned off auto screen brightness OFF, because it just doesn't work.
I walk out to sunshine and the screen won't brighten and when I walked inside it won't darken so I ended up manually changing the brightness.
Here is the interesting (or rather annoying) part: When I turn the brightness up, it seems like it makes the whites more glowing, while the dark /black (let's say a shadow of a tree) just either stays too dark or turns more grey, instead of brighter. It's like the brightness control is controlling the exposure and contrast only.
Despite I see youtube videos talking about its 4K video capability, I think this phone makes terrible videos, especially how the camera applies too much contrasts and the HDR doesn't help it.
I also believe, that it's not all and every single device have this problem, because I'm sure I'd seen more complaints. It's just horrible quality control, and that's Lenovo for you.
I tried color tuning apps, but nothing seem to work. It probably requires a root but since it's an Amazon phone, it won't help it. So the phone works great as a phone, it just have an awful screen and a mediocre camera
This phone may have been enough in 2016 and 17 with these weaknesses as a budget, but seeing all the new budget Chinese phones coming out this year, I would not recommend this phone unless you can pick it up for $100 or less.
This phone is going into my drawer as soon as my new LG G6 arrives and the G5plus will be only used as a backup phone. There is no way I would keep using this as a daily driver unless I have no other choice.

Screen Calibration

Can anyone share their screen calibration settings? I wanna get the best whites possible. On my N9 I used to decrease the reds all the way to zero and my greens about halfway but this is a new phone with a different display and those settings aren't doing the same thing. So I just wanted to know what everyone was doing. Thanks.
I think natural mode supposed to be pretty much calibrated already and if you still wanted to tweak it more there is cool/warm white balance slider and rgb sliders.
There is whole bunch of tests here http://www.displaymate.com/Galaxy_Note10_ShootOut_1G.htm.

Natural mode can't be further adjusted. You have to choose Vivid to adjust RGB and color temp.
As far as best settings, it's difficult to say what yours should be. If the Note 10 is anything like the Note 8 or Note 9, you can lay four of them down next to each other with stock settings and they will all be different.
My Note 10+ seemed to have too much green tint and maybe just slightly cool. I left temp alone and just knocked green down one notch. But honestly, these screens are so close to perfect you can just leave it stock. Just play around with it, adjust it back and forth until it looks good to YOU. You're the one staring at it.
I have compared four Note 10+'s side by side, and all had different white points. Also, Natural mode was significantly greenish (maybe slightly yellow too) on all four devices. Personally, I feel like my Note8 has a better panel.
According to article I linked above and here again http://www.displaymate.com/Galaxy_No...hootOut_1G.htm Natural mode supposed to be calibrated and automatically switch between sRGB and DCI-P3 depending on content. (I guess sRGB for pictures and web, DCI-P3 for 4k TV) and can't be easily adjusted. Then there is Vivid mode which uses full color gamut, display is capable of showing and you can adjust it with sliders to your liking or calibrate using instruments. I can't tell you if all phones are properly adjusted at factory (probably not), but according to article the one they had was right on the money and mine seems to be fine as well. BTW the eye can be easily fooled and calibrating instruments are the proper way to adjust it, if you need it. Yet, it is my phone, I don't use it for pro use, so I adjust it the way I like it and mine is set as vivid and gray seems to be neutral gray as far as I can tell without any tinkering. YDMW.

One of the failings on Android, no color calibration.
You simple can't do it by eye and get all the parameters right.
It's fine for viewing but not editing photos until a company like Spyder steps up to the plate with a 3rd party calibration apk and tool.
Mine seemed best in natural mode with a slight amount of red added with an overlay apk and night mode turned at about the 10 or 20% level.
Lol, enough.
Just don't edit photo colors, temps etc. with or you may get a very rude surprise.
