Is there a quality difference between the HDMI outputs? There's a cheap tablet at Walmart for $80 with HDMI output on it. Figured I'd save $10-15, but also get use of the tablet too. Also: Obviously if the USB came undone the FPV view would be lost to the HDMI output on the tablet, but what happens with the DJI controller since there's a separate connection on it for the HDMI and USB? Would you lose video connectivity then? If running Litchi and you've programmed in Waypoints would it come home or continue the programmed mission if the controller's connection were lost?
