How to modify the IMX8 Android's default resolution(the default value in Physical size of 'wm size')

We're running Andorid9 on IMX8mini, the default resolution is 1920x1080, we want to let this default to 1280x720

We already knew this can be done by 'wm size 1280x720', or use overlay. Both of these methods are for overlay way, i.e, when I execute 'wm size', it would show the Physical size is not changed:

# wm size
Physical size: 1920x1080
Override size: 1280x720

When I execute 'wm size reset', it would go back to the original 1920x1080.

So, I want to let the Physical size be 1280x720, can anyone help me? Because all what I searched are the 'wm size xxxxxx', this is not what I wanted.

 

Thanks

You may need to change the default resolution in the bootargs. Please refer to the Chapter 6.2 and 8.1 in the Android User's Guide for more details.
