Apple's first 4K-capable TV box outputs through a single HDMI 2.0 input at 18Gbps, supporting 4K@60Hz and Dolby Vision for streaming content. The Gigabit Ethernet port provides rock-solid connectivity for streaming apps without Wi-Fi reliance, and the USB-C charging port is service-only with no external storage support. The optical TOSLINK audio output routes surround sound to compatible soundbars independently from HDMI. Here's every port and the cables you'll need.
4K HDR streaming media player with HDMI 2.0a output, built-in Gigabit Ethernet, and IEC C8 figure-8 power inlet. Supports HDR10, Dolby Vision, HLG, and Dolby Atmos audio via Dolby Digital Plus.
