Colorbanding defeated

Danishblunt

So as of today the 21.03.2021 color banding has been defeated. Now at the beginning I was under the impression that the crappy color banding was caused by pixelworks and guess what?
It wasn't.
Infact the reason this happened was actually because of ASUS not wanting to implement any type of gamma correction at all, while other manufacturers like nubia and oneplus have infact added gamma correction in their kernels. So today I simply stole some code from Oneplus 8 kernel like the naughty naughty boy I am and magic has happened. So what are the results of this?





Now as you can see the difference is absolutely insane. Blacks have returned, no pixelation and the screen looks absolutely georgous! Honestly this screen after calibration seems absolutely amazing, ASUS was not lying when they said that these panels are actually high quality. Granted the quality of the screen cannot be seen in those pictures very well as smartphone cameras have great difficulty catching stuff in the dark with huge amount of details. I took a closer shot as well to show that even the black crush is quite in check as well:

How exacly an absolutely new guy like me who has extremely little experience with kernel development could fix an issue i looked at in weeks while the experienced asus team didn't get the solution until this date is beyond me right now. I hope that the devs will fix it very soon now that they know they can simply nab code from nubia or oneplus and some modifications, today my SSD died with my ubuntu and kernel sourcecode on it, so only thing I have left is a flashable zip file that would most likely crash on 75% of rog3 devices due to extreme amount of undervolt, i will still share to those who want to try, but successrate won't be high :'D
At this point I want to thank Freak07 for introducing and helping me to get into kernel development much faster than I would have taken by myself.

@Anders_ASUS @Gustav_ASUS can you guys please reply something here..
If the fix is in kernel level whats taking you guys so long to fix this ?

You cannot expect mods to comment on a technical development issue, they are not devs but mods. Please don't ask them to explain anything they can't.

But they can communicate to dev team regarding information in this thread.Atleast I am expecting that should happen.

Asus must be sweating rn thanks to you,we could see a fix soon

But since I have no idea of rooting and such,do I need rooting? Is is a custom rom? Do share details or even a tutorial on how we can get the true rog 3 screen

If you can't do it here do It on your youtube channel which I'm interested in knowing

And about oneplus and Samsung, Can you import code from other displays like iphones or Red magic?

Why are you all acting like this is some sort of battle? Why would ASUS sweat in any way?
This is a custom kernel based on Freak07's Kirisakura kernel, meaning it will require magisk and such. Remmber while this is the definitive solution to the color banding problem this is still very undesirable for anyone who want to keep their warranty. Since unlocking the bootloader will mean your warranty is gone.
You don't import code from a display. ALso don't get the impression just because you calibrate a screen it can become a god tier screen. Calibration only means you get the most out of your screen, meaning if you have a cheap screen, even if calibrated it won't surpass a high quality screen.

First of all,I meant that they would be quite in a hurry now that there's been a solution and try to publish an official fix
And secondly,how much calibration can someone actually do on this screen? Is there a limit that the device specifies? Or is it just calibrating to a similar level as other manufacturers?
