modify the kernel source code from 1920x720p to 1280x720p

How to modify the kernel’s source code from the screen resolution 1920x720p 60Hz to 1280x720p 60Hz?
How do I turn off the adaptive resolution of the screen in the kernel’s source code?

Thankyou very much

Dear 2284810331,

Please see “Display Resolution Configuration” in below link. Thanks.

Dear SteveNV,

Thank you very much for your answer.
I can successfully change the resolution in the first way of the documentation which you tell me.

Thanks again for your answer.
