It has 3 HDMI ports, one of which is eARC. If I understand right, the eARC output carries both sound and video, so you can connect to game consoles, sound systems or other devices without using a separate audio cable. You can see the HDMI ports in the attached photo. Two have access from the side, and the third has access from the back. The back-facing one is in the middle, just above the optical output.
