Hola!
OK, at some point I will finally update the calib.cfg file again. But for now here are the settings I am using with a KCAL enabled kernel to remove ghosting from my screen as well as drasically improve contrast and colors.
I use Kernel Adiutor:
-------------------------
Under 'screen' section >
Screen Color (This kills the ghosting a lot of users are experiencing as well as removes the blue tinge the screen has):
Red = 250
Green = 250
Blue = 235
Minimum RGB value = 35
Saturation Intensity = 27
Screen Hue = 1520
Screen Value = 112
Screen Contrast = 132
---------------------
I have been running it for awhile and it looks fantastic and I have not had anymore ghosting. It also makes the screen look similar to my Note Edge when I first got it. Contrast is improved a LOT. Colors are better. They are not over saturated. Very close to natural. Whites are white and not blue (at least on my display) etc.
Please let me know your results.

Works good here!
any way to change these values without root as I updated to the new tmobile update and atm there is no root method

I don't think so, no. These require a kernel with KCAL integrated. You can kinda adjust the screen values without root by going into settings > general > accessibility > vision > screen color adjustment > manual
But that's about the best you can do beyond nonroot screen filter overlay like cflumens supports etc
Thanks Helf. with this tweak, the display looks great!
by ghosting you mean image retention right? if that is the case, well this is awesome! Thanks
A little bit over 15 hrs and no ghosting. My only beef is how the blues look but it's a good configuration overall, easy on the eyes.

How do the blues look? I need to put the phone with a color calibrator and check it. Mine look pretty close to natural when I eye ball it. I'll keep working on it

You're doing a great service for us all. Blue's and greens come off slightly dull like they could use a little saturation but if it's at the cost of prevent the ghosting effect i understand.

hm. The colors in general are probably a little duller. The vibrancy and contrast and all is usually cranked up on phones Samsung is especially awful about it. People like the 'pop' though. I just compared several shades of blue and greens with the screen at max brightness using the camera app, the colors are almost dead on to my eyes. Granted i have to manually drop the ISO a couple notches because the phone wants to automatically crank it too high (like true-to-life brightness/colors around my work desk it wants to use an ISO of 600 and ISO 200 was real world accurate. heh).

You have spectrophotometer? I would love to see some values to use, but wouldn't it be different between devices? No panel is exactly the same, or?
I seem to remember that being reiterated quite a lot on various display discussions I've followed in the past.

Yeah. I don't have a fancy one. It's old but works lol.
There is a variance between panels but it's not as severe as it has been in the past.

Been trying these settings for a while, personally I really like them. Thanks Op!
Anyone else have any settings to try?
Do you use these settings along with Comfort View? Or do you leave the Comfort View setting turned off?

Just tried it as well on H918 running WETA with stock kernel and it installed and activated properly but nothing changed. Tried a few different configs and reboots just to see but nothing. Thanks for the share though. It'd be just what I'm looking for if can get to work
Is there any chance applying these changes would cause auto brightness to stop working? Possibly it's coincidence, but I changed my screen settings to exactly how it was in the OP, and since then I've noticed auto brightness no longer works on my phone? I don't see how making these changes would cause that but I figured I'd ask here to be sure, or to see if anyone else has the same problem.

Does anyone know if there is a way to adjust the display's color saturation and color balance? While the screen is eye popping to look at, the colors are not accurate. They are distinctly warm and oversaturated. This is great for looking at icons, but not so great for photographs. I know the international Galaxy S II has something called "background effect" where this can be set to 3 presets with varying saturation levels. But this option is missing on the AT&T SGS2. I found an app called Screen Adjuster in the market, but that only lets you increase saturation or change color balance by increasing the intensity of the Red, Green, or Blue values. There's no way to turn them down.
So has anyone figured out a way to adjust this? Thanks.
bump. also hoping to find a solution for this but not having any luck yet
+1 on this.. I am a professional photographer and I used to use my I4 to present my portfolio. As of today I can't do that, or I have to do re-do my portfolio specifically for the SGS2's display. Which I really don't wanna do.
"app called Screen Adjuster in the market"
Thanks for this! At least with that the color temp is somewhat fixable, but overall colors are still terrible. As long as Samsung insists on locking these devices into torch mode we're just screwed. It's a shame that this didn't ship with several selectable profiles like the regular version (although I never seen it so dunno how good that implementation is.)
Working on hardware calibrated monitors all day and then looking at this phone is a bit jarring.

This would be great. Caartoonish is exactly what it it. However, we need to keep in mind these displays are far from professional grade. I won't argue that some software could help bring a small level of 'professionalism', however.
I just read around the web that the international version of this phone has Settings, Display, Background Effects to calibrate?
------------------------------
Well I checked out Screen Adjuster and it has the ability to change R,G,B values along with the brightness and Contrast ... so that's enough to for me to use me Eye-One Pro to calibrate the screen. I just need to put grayscale and R,G,B targets to the phone.
This should work just fine
can you post your settings when you calibrate it?
I also found this
Calibration Hack for Nexus One
Which I am now using. Since it has the grayscale bar built in. But this one requires Root access as you need to put the apk in to the /system/app.

Great find! Do you know if CM7 is a requirement for this? This may be the best option for color correcting the display.
I just realized that with Screen Adjuster, you can change the color balance by adjusting the relative values of RGB, then turn the Brightness down to compensate for the elevated brightness levels. Without turning down the Brightness, the black pixels are no longer black. So it's a pretty decent solution.
Just got Screen Adjuster, are there any recommendations for "optimal settings?"

I'll look into this - I'm surprised you find yours too warm, I think my phone is a little on the cool side - without a doubt bluer than my Infuse.
If it's supported by the I9100, I can probably find the relevant kernel interface.

Problem is... just like calibrating a TV/Monitor is that it doesn't have High Bias and Low Bias R,G,B. High Bias changes the whites and Low bias changes the black.
Also, unless you plan on using your display at a constant brightness level, you will get color shift in the lower end of the spectrum
For what I have done is create an 18% gray jpg and a 82% gray as well as a 50% gray.
ON MY display the whites is on the warm side... but there is nothing one can do about it, because the apps just don't have those value to change
ON MY display the blacks are also very warm...
I WAS able to use my i1Pro (spectrophotometer, unlike the cheap colormeter) to get it pretty damn close to 6500k in the Black and Mid-tone.... again nothing one can do in the whites.
I am 90% happy with the results (I'm anal, but I can't do anything with the whites!)
My settings might get you close to 6500k (most likely not.. because ever display is different, and from what I see here some are too warm/cold..etc).. My settings are to use with Calibration from the Nexus One thread, and they are set up to have a warm mid-tone
Red: 627, Green: 623, Blue: 665
Mind you that I also am using CM's 7.1 with the brightness custom level set to my likings...
But it's night and day difference (if you are looking for realistic color representation). A lot of untrained eyes like the eye popping colors, while a calibrated display is much more subdued.

I keep getting a force close after I install the apk. What version did you use? The app installs fine and will open but when I try to adjust RGB, I get the forced close. Thank you!
My prime has always had this issue since I got it and has seemed to stick thru resets and new firmware. It looks to be a gamma issue washing out light colors. Any idea what I could do or need replacing?
AOKP has some gamma options, don't know if work though.

up your device to performance mode, and max brightness. see if it looks better. ive noticed the auto settings from asus dont just change brightness and processor voltage. it seems to change the OLED power. on power saver its obvious on mine.
all icons looks muted, hard to read. turn to performance and its sharp.
dunno
You know what? Changing to performance actually changed the gamma a bit and its much better looking now. That's crazy, I had it on balanced. I'll test it out some more and see if its good to go and see if I can get some shots of the difference.

My brothers has cool whites and I have warm whites...yet our panels are both Sony...so I don't get it.
mine is also a warm-toned screen, nonetheless it looks great
I posted about this yesterday but it already got buried. Unfortunately you can either hassle with taking it back and hoping for a more blueish white panel or you can get used to it. I hated the look when i unboxed, I have the same yellowish tint on white. But im already used to it for the most part. There is an app on the play store called "Screen adjuster" that you can add some blue back in but its not perfect and it has to run in the background i haven't tested to see how much of a load it puts on the phone if left on all day. Also a good app to use to visually inspect the colors your panel is showing is "dead pixel test". So software can be used to help the tint, but as far as a permanent solution, I believe that would be up to HTC. Maybe some devs can do it eventually once we have s-off.
I've just starting to really notice this, and its driving me nuts.
The whites are not white at all, they are more yellowish eggshell (or as I like to call it 'light puke'). You can really notice it when your in natural light. I held it up to something pure white and you can see an epic difference.
Does this not bother anybody else? I forget, but don't some ROMs (for other phones) have options to change screen tones? Is this something that I can look forward to ? Or perhaps my eyes (and mind) are just playing tricks on me.
I dislike 'warm' tones a lot. I wish I gotten a 'cool' tone phone instead, I can handle the blue tone a lot better.
I wonder why this is I mean it isnt like amoled n the screens should be.the.same.... Maybe dim lights inside?
Root it and try chainfire 3d, it has the option to change screen tone in I believe the pro version. Added bonus, works with all roms to my knowledge. I haven't tried it yet myself as I'm completely happy with the tone on mine, but I used it on the og evo for a long time.

Thanks, I'll give it a try since I'm already rooted. I messed around with 'screen adjuster' and 'filer your screen' and neither seemed to do the trick.
EDIT: Looks like I'll have to wait a bit longer to play with chainfire 3d. Requires S-off (or probably just unlock bootloader). Only have root. But chainfire looks promising.
This was a problem on the One X for AT&T but most of them cleared up after a week or so. My advice would be to keep the brightness up for a while when using it.

We have two EVO LTE and one of ours is much cooler and blue and the other is much warmer. How do you check if the display type to see if they are different?
My screen is warm also. At first I thought it was the ZAGG HD screen protector that was causing that yellowish tint, but after I removed it, it was still there.
If anyone with two EVO LTE phones can post a side-by-side picture of the warm and cool screens, I'd greatly appreciate it.
TIA
Here is a picture. Its not the best quality so it might be hard to tell a difference. The difference is much more apparent in real life.
Supposedly its due to the adhesive. There is a thread about it in the HOX forum. My screen seems to be whiter than it was a week ago but that may be a placebo effect- I need to do another side by side comparison with my iPhone to tell.

I was dreading a problem like this. I can deal with blacks not being black (have to deal with it with the very nature of LCD) but whites... Yeah, they need to be white.
Here's to hoping my device doesn't have this issue. I will update this post with news.
get an app called screen adjuster
then increase the blue a little bit, to about 15 or so
woooooorks wonderss!!!
On my NS4G, there was a kernel mod developed by SuperCurio that allowed you to adjust gamma levels. I always ran my phone with very cool blue whites.
Maybe something like that would be possible for the Evo?
I think I have the warmer screen color. Things like this doesn't bother me at all. I've seen thread like this everytime a new phone comes out. After a few week your eyes and OCD levels will adjust.

You can def tell the one on the right is the warm though. I'm sure in direct natural light the difference is huge.

Same. I can deal with the black but not the whites. Whites need to be crisp and clean not yellow. I repainted all the eggshell whites in my house to pure white. To me it takes away the crispness of the screen.

Man you hit the nail right on the nail. I had mine set at 14 for the past three days. It helps but it still isn't ideal. Plus its consuming resources.
dont think its an adhesive bonding process still "curing"
i think the color temp is permanent.
hopefully a dev will allow color temp change because its a little awkward staring at my pc monitor, then looking at the phone's brown and yellow drab lcd tint.

This is what I am praying for. But enough people have to be annoyed by it for somebody to do something.
The best test is to open the settings menu (Evo white) and compare it against a piece of notebook paper (real white). Its gross.
Just received by OP2 today. Initial thoughts are that it looks and feels very similar to OPO but the screen is a definite step backwards. Colors seem washed out, and even at full brightness it is dimmer then my S6 at ~40% brightness. Viewing angles also seem poor.
In my mind this is a bigger issue than lack of NFC or quick charging. The screen is the one thing you're constantly looking say on a phone, not some feature. It almost seems like the screen on this phone was an afterthought.

AMOLED screens have infinite contrast which makes them bright and punchy. Going back to just about any LCD it will look washed out.
KCAL COLOR PROFILE Amoled Style:
Colors: 255,255,255
Saturation: 285
Hue: 0
Display: 255
Contrast: 264
Gamma: 0

Yes the screen is washed out compared to my note 5....not surprising really given the technology. However the more annoying screen issue is the constant dimming of the screen when darker screens are presented even when the adaptive brightness is off. The screen is constantly fluctuating and it bothers the heck out of me. Might need to use a custom rom just to get rid of it. Or sell the phone. Whichever comes first. Haha.
I'm disappointed as well, coming from the OPO. The lack of color tuning - no, that placebo slider in O2 2.1 doesn't do anything - leaves the screen with a too low gamma and too high color temperature, resulting in washed-out and cool-looking images. Stock OPO wasn't that great, but at least could be tweaked. No, I'm not looking for the overhyped Samsung AMOLED look that people equate with proper color rendition. I'm a photographer and all you need to do is put the same photos up on a computer monitor - even a business grade one - as on the phone to see how lackluster it is. By itself, it doesn't look terrible, but it's clearly not accurate.
I've got my opo2 yesterday and:
1. Screen is yellowish on the bottom! I read about it before, it was opo1 issue, but it seems to be opo2 issue too :////

Well, not at all... Unless I slide it 100% to the right, then whole screen is yellowish and bottom part is even more :/
I'm hearing many complaints about the screen from folks who haven't removed the factory pre-installed hazy plastic screen protector, either because they don't realize it's there or if they do don't imagine it makes much difference. Captain Obvious' pro-tip : take it off, the difference is huge (or YUGE if you're from Brooklyn).

One interesting thing that most people aren't talking about is the fact that Samsung's new displays are actually TUV Rheinland certified for significantly less blue light emission (advertised 42% reduction), while still maintaining optimal colors and picture quality.
To me this is a huge selling point. Most people probably don't care, but blue light is shown to cause significant eye strain, and slow the development of melatonin in the brain., destroying your sleep quality. Just curious on everyone's thoughts about this.
Here's some more info if anyone's interested;
https://www.samsung.com/global/galaxy/galaxy-s10/design/
https://news.samsung.com/us/samsung...rp-reduction-blue-light-emission-oled-panels/
Samsung discussed it at their event. Reviewers/Youtubers and tech sites rarely comment on blue light emission. You'll come across more articles on how to kill Bixby! The Honor 8X was certified too, but few speak about it.

Blue-light filters usually make things yellow, but I checked the s10/s10+ in a shop and the display is PERFECT, the white levels are incredibly pure and it looks cleaner than my XZ1's IPS which I thought would have unbeatable whites when compared to oleds, that's no longer the case.
I always hated OLED but Samsung found a way to reduce its drawbacks while creating a super accurate panel, if you want to buy one last AMOLED device while waiting for Micro-led to be a thing in mobile, this looks like a very wise choice.

They're still trying to shrink it for the average TV size, I hope it will come soon.
Did some more research on the Honor 8x, it appears they are advertising blue light reduction with their "eye comfort mode" which tweaks the colors you are seeing. While on the other hand, Samsung is pointing out the 42% reduction from previous OLED's still maintains the same colors you're seeing. So based off that, the S10 is capable of reducing exposure without software tweaks.
It also appears that out of the box, the S10 is defaulted to the "Natural" color setting, and provides a "Vibrant" setting, which does increase color saturation. I wonder if the higher color setting changes your exposure by much...

Then the Honor 8x's solution is nothing more than a software re calibration tweak, I'm glad the S10 comes with a hardware solution that doesn't impact viewing experience.
But yeah using Vivid mode will increase your exposure to blue light depending on the displayed colors, I wouldn't worry that much, it is in no way as dangerous as the exposure to TVs, Desktop monitors or even daylight.
Can someone link to a bluelight study that shows its harmful. I lost my ebsco access when I left college. I always thought this was an overreaction. I've been staring at cool temp computer screens since the 90s, and my recent eye exam says my eyes are still perfect.
I've found the press release, but no peer reviewed papers.

Glad to know I'm not the only one. I even wear reading glasses with blue light filter due to my extreme light sensitivity, so yes, totally big deal for me too
Pwm is for losers. Now Sony is also on the oled bandwagon.
