I got an Amlogic S905 box, and when I play some video file, before the video is starting I got black screen for 3-4 sec than I see the CEC message on TV top right “HDMI 4” port and then video start. I don’t know why this happens. I tried to disable CEC from input -> peripheral, but with no result. I’m using latest version 9.0.3.
i made some shell test:
My Sharp have 4 hdmi, and the box is on hdmi 3
