Overview

The Roku 4850R streams in 4K UHD and connects to a TV over HDMI, with Ethernet, USB, and Bluetooth on board along with Wi-Fi 6. It targets anyone assembling a home theater setup that wants a wired network option alongside wireless.

Roku's own spec sheet lists this unit as part of the Ultra line with Wi-Fi 6, which is worth knowing since the color field in the data just says Ultra rather than naming an actual finish. Ethernet plus Wi-Fi 6 support matters most for anyone streaming 4K content on a network with other heavy devices competing for bandwidth. Bluetooth is on board too, which typically covers private listening or a Bluetooth remote rather than just casting from a phone.

Who it's for

Suits a household setting up or upgrading a TV that lacks smart apps, especially where a wired Ethernet connection is preferred over relying on Wi-Fi. Also fits anyone who wants Bluetooth audio support built into the streaming box itself. Less relevant for a TV that already runs its own smart platform well.

Performance notes

Video output reaches 4K UHD over HDMI. The combination of Wi-Fi 6 and a physical Ethernet port means the connection method can be chosen based on what the router setup actually supports, rather than being locked into wireless only. USB rounds out the port selection for local media playback.
