Question: how do i connect my roku to my vizio smart tv?
Answer: The Roku device plugs into to wall for power, and then into one of your TV's HDMI ports. You will change the Input on your TV to match the HDMI port you have connected the Roku to (e.g. HDMI 2). Once you do this, you will see the Roku setup screen and will continue from there to connect to the internet.
