eARC on Mars Pro


New member
Quick question,
Dangbei Mars Pro has 2 HDMI ports and one of them supports eARC. I have a console and an android tv box. Can I use both ports exclusively for video output from those 2 devices or is eARC exclusively for audio signal?


The thing is that earc hdmi does not display any output...I tried with everything
What do you mean? The HDMI of the projector is only the HDMI input source, it is not the HDMI output source. When the HDMI of the projector is used as ARC, an external amplifier is connected to achieve the function of audio output.
