Dear Sir.
I update my Dasaita 1280x720 model to this file HA3_rk3399_10.0_ota(20211015)升级包 and used MCU : 3.78 from this post https://xdaforums.com/t/dasaita-latest-mcu-and-updates-for-dasita-px6-1280x720-max10.4173669/post-85845447
The result bad colors which I believe is not the right resolution for 1280x720 screen as in the photo attached.
Please can you direct me to the correct files to resolve this issue.
Thank you so much.

Hello.
Thanks for your message.
For further confirmation, please go Settings > Car > Factory settings(password: hcttest01),
and provide us with a picture of the screen parameters which is at the bottom.

Thank you for your answer.
I think I solve the problem by doing this:
I used DMCU.ext file along with MCU 3.78 mentioned above but I had changed the number on the DMCU.ext file from 12 to 13. And did MCU update, and the screen now is fine with the correct 1280x720 resolution.
DMCU.ext file I got from this post: https://xdaforums.com/t/dasaita-latest-mcu-and-updates-for-dasita-px6-1280x720-max10.4173669/
For the general knowledge: is this the right way to do it or there is another way for the general benefit.
