Question 2: What should I do if the video receiver is too wide to fit into the HDMI port on my TV?

  • If the video receiver is too large to fit into your TV’s HDMI port because of surrounding cables, use the included 6” HDMI adapter for a better fit. Connect one end of the adapter to the video receiver, then connect the other end into an HDMI port on the back of your TV.
