Hi,

The default resolution of rk3288 is 1080p @ 60fps, my project may need 720p@30fps to save much of the system resources e.g. GPU/CPU power even maybe acceleration of surface rendering.

Would you guys give some tips, thanks in advance~

sincerely

Maye

Hi,
To set the resolution to your needs, you have to modify the Drive Tree file of Kernel located in <kernel_source>/arm/arch/boot/dts folder and compile the kernel again after setting your required resolution.

This is same for both Linux and Android.
So read the manual of how to compile the Kernel for Android or Linux and you can get it done.

Cheers,
