This 4K HDR disc player uses a dual-HDMI design so you can keep video and audio on separate cables: HDMI OUT 1 carries 4K HDR video plus audio (HDMI 2.0a, HDCP 2.2, Dolby Vision), while HDMI OUT 2 is audio-only for older AV receivers that can't pass 4K. An optical TOSLINK output adds another digital audio path. Wired networking runs over a 10/100 Ethernet port rather than gigabit, and a front USB 2.0 port plays back media files. It powers from a figure-8 mains cord.
