Question: are vizio tvs compatible with roku?
Answer: Roku devices generally attach to a TV using an HDMI port. Your Visio smart TV should have at least 1, and possibly as many as 3 HDMI ports. Your home must also have WiFi so that the Roku device can connect to the internet. The Roku device plugs into to wall for power, and then into one of your TV's HDMI ports.
