If your display is showing “no display detected” it is not receiving the HDMI signal from Rockbot. You might need to turn the display off or swap inputs to reset the HDMI handshake and restore the image. You will also need to make sure the Rockbot is powered on and that you are using an HDMI cable shorter than 50’. HDMI signals will not go past 50’ unless boosted properly. In addition, most HDMI cables over 30' feet are directional, please make sure the output end of the cable is near the screen.
