The Dual HDMI connection mode ensures that you can enjoy the highest possible video quality and resolution, in addition to high bit rate audio content. Use an HDMI cable to connect the HDMI OUT (Main) output to your TV, and another HDMI cable to connect the HDMI OUT (Audio Only) output to your receiver.
The configuration below will allow you to send the video signal (3D or UHD in this case) directly to the TV and send the audio signal to the receiver.
