Video is via HDMI with stereo sound fed from the analogue jack to an amp. I have cut a section of cable insulation off the HDMI cable to get the cable to bend neatly to a hole cut in the base.
I will change out the countersunk screws on the mount to round heads and also fit a right angled PSU connector when they arrive from ebay/amazon.
