Colorbanding defeated

Hall of Fame I
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.

Pretty sure he will soon implement this solution in his kernel as well, hence I'm not to worried about my dead SSD, only thing annoying me now is that I have to get a new one, reinstall crap and start from scratch again with my kernel, ohwell 😞

I totally agree...but experience is to just fix the issue but experts like you find the root cause which helps experienced guys to fix them 🤣

Seriously don't call me an expert 🤣
It's like calling a truck driver who has basic knowledge over medicin a doctor 🤣
I do programming in different languages that's all there is to it, all I'm good at is connect dots and debugging, if i had to actually add something (from scratch) instead of modify for instance I'd have a hard time due to the extreme lack of C knowledge and linux kernel development as a whole. As mentioned people like Freak07 and tbalden stomp my knowledge into oblivion.

Batman 2021 trailer, make sure its non HDR as otherwise you get a disgusting yellow tint. I used the one named: THE BATMAN Official trailer 4k (2021) Ultra HD.
I used that trailer specificly because it caused by a large margin the most color banding. Especially at 55-80% the color banding was insane.
Make sure to watch in a dark room so it's even more emphysized. You'll see it looks like on the images linked in the topic.

Sometimes this forum makes me wonder whats going on lmao. Edit -> mod approcal needed: Ohwell here we go again:
I used the batman trailer titled: THE BATMAN Official trailer 4k (2021) Ultra HD
Make sure you watch a batman trailer that isnt HDR as otherwise u get a disgusting yellow tint, the color banding is especially noticable in 55 - 80% brightness. Make also sure you watch in a somewhat dark room so you can notice them even more, it should look similair to the picture above where blacks are washed (at higher brightness) out and pixalation happens all over the video.

I wonder now with your basic knowledge, you are so good at it . what happens when you become perfect? So being a truck driver you know how to drive..but guess Asus made an accident here lol..😜😂😂😂😂
