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.

Great work Danish.
I also would like to try it. Currently on .132 and freak07 s 2.1.1 kernel. Can your kernel be flashed over freaks kernel.

Thanks

@Danishblunt wondering is adding dc dimming possible on rog 3 screen? My eyes is more sensitive and found rog 5 screen with dc dimming more comfortable to view

It is based on kirisakura kernel, it's no problem flashing over it regardless of kernels origin.

Been on this kernel about 4h. Then revert back to stock for comparison. All I can say is, this kernel and its fixes really works. The "black crush" totally gone. Here some proof photo.

Brightness is set to 40. Lower than 40 tend to make camera unable to focus properly. If u see purple light in the picture, its come from OG Pixel laser focus . Due to my acc forum level, I can't post link yet, so here a couple of picture for comparison.

Here the link for other more picture. Most picture are from Batman Trailer. Some from GoT, and ZS JL.

If you see purple light on the image, it because capturing image in the dark is difficult. So i had to use laser focus on my OG pixel.

Not gonna lie, your photograph skills impress me, I know how dofficult it is to get good low light shots while having a small light source shining at the camera 😮
