Roku's entry-level 4K player streams up to 2160p at 60fps with HDR10, passing Dolby audio through its single HDMI 2.0a output to a compatible TV or receiver. There is no Ethernet port, so it relies on 2.4/5GHz Wi-Fi for every stream. A Micro-USB port supplies power from the included 5V/1A adapter, and Roku recommends the wall adapter over a TV USB port for reliable 4K. Below you'll find each port and the cable it needs.
