According to Roku, Roku® streaming players (including the one built into the Roku Streambar™, Roku Streambar Pro, and Roku Smart Soundbar) can be connected to any TV with an HDMI® connection. If you have a pair of Roku wireless speakers, they must be connected to a Roku host device such as a Roku TV™, Roku Streambar, Roku Streambar Pro, or Roku Smart Soundbar; and will not work with other TVs or Roku streaming players.
All Roku streaming players, including a Roku Streaming Stick, Roku Streambar, Roku Streambar Pro, and Roku Smart Soundbar, will work with any television with an HDMI connection. However, certain features such as 4K Ultra HD or HDR require that you connect your Roku player to a compatible television that can support these features.
Aside from a Streaming Stick, when connecting a Roku streaming player to your TV using an HDMI connection, we recommend you use a High Speed HDMI Cable if your TV only supports 720p and 1080p, or a Premium High Speed HDMI Cable if your TV also supports 4K and/or HDR.
