Hello,


I want to support HDMI resolution to 1920x1200 (WUXGA) for Android 7.1

So I modified device/rockchip/rk3399/rk3399_firefly_aio_box/system.prop like below, and then rebuild firmware and download it.


persist.sys.framebuffer.main=1920x1080
    =>
persist.sys.framebuffer.main=1920x1200



Fortunately, HDMI output looks good. It seems that HDMI output is set to 1920x1200 resolution correctly. :-)



I'm wondering that this is all? Do I MIGHT need an additional modification?
Because I used Firefly-RK3288 reload before, at that time I have to modify some kernel configurations (ie, dts file) for same job.

But for Firefly-RK3399, I couldn't find any resolution related code in dts file, so I didn't modify any kernel code or configuration.



Thank you in advance.


Best Regards,
Sinjin
