Question: how to set up roku on my vizio smart tv?
Answer: Also make sure the HDMI cable is connected between the Roku 4 and the HDMI 2.0 port on the Vizio TV which is labeled at 4K@60hz. Turn on the TV and once you have the right HDMI input port selected, you should see the dancing Roku logo. The first step in the setup process is to pair the remote control.
