Hi, we bought a Matrice 30 T. After initialize and upgrade remote controller firmware, the controller doesn’t power the display. The controller can power and when I put the HDMI the image is shown in TV, but the image in display is black. I think it’s not a defect in display, but in the firmware. Could you help me?
