There is no error message
Not even in the console?

@jsulm Yes, it works on pc ubuntu 16.04. The qt version on board is 5.9, but 5.12 on pc.
Here is another message sometimes it shows:
[ 13.884117] rockchip-vop ff930000.vop: [drm:vop_crtc_enable] Update mode to 1920x1080p60, type: 11
[ 13.919835] [drm:hdmi_config_hdr_infoframe] ERROR Not support DRM Infoframethe board is connecting an aoc 1080p monitor by hdmi.
I have checked the error msg, it just means no infoframe for hdmi version less then 2.11a, I dont know if this matters, because I can play video to the same monitor correctly.
Sorry I`m new so have to wait 600 seconds to send another text here.
