Walmart's onn. 4K Pro is a set-top Google TV box that outputs up to 4K over HDMI 2.0 (not HDMI 2.1), with Dolby Vision and Dolby Atmos passthrough. It stands out at its price for a wired 100Mbps Ethernet port and a full-size USB 3.0 Type-A port for external storage or accessories. Power comes from an included 18W AC adapter into a DC input, so there is no USB-C or figure-8 mains cable. Below you'll find every port and the cable you need to connect it.
