Access HDMI of Unitree A1

Are the HDMI ports of both Raspberry Pi on the Unitree A1 robot active? Connecting them to a monitor gives no video stream of the Linux OS running on the Raspberry Pi.

There are two pcs on the robot. The front side of the robot has some ports they are for Rasberry Pi. Here you can connect the HDMI cable and than restart the robot because if the robot is turned on and than you connect an HDMI adapter it will not show anything. So you’ve to restart after HDMI connection.

I think getting connection to Rasberry Pi and its ip is enough but you can do the same procedure for the other main PC for robot communication.

Canceled. My monitor has trouble to connect to any computer with its HDMI-DisplayPort cable. HDMI connection worked with a different monitor.
