Each Roku player comes with both composite video and analog audio (red/white/yellow) cables to connect Roku to virtually any TV, right out of the box. Other Roku models also support HDMI, component video and/or S-video connections.
Tip: To order HDMI and component cables for the Roku Classic HD, HD-XR and all current Roku player models, visit www.roku.com.
The general rule is this – use a set of cable(s) that provides both video and audio signals to your TV.
Best: A HDMI cable delivers both video and audio signals to your TV in one single cable.
Better than Better: A component cable for video (red/green/blue) and an optical cable for 5.1 surround sound. (Note: this applies to the HD-XR and XDS Roku player models only)
Better: A component cable for video (red/green/blue) and composite RCA (just the red/white connectors) cable for stereo sound. (Note: this applies to the HD-XR and XDS Roku player models only)
Good: A composite RCA cable set for video (yellow) and stereo sound (red/white). This cable set is included with every Roku player.
You can use any option above to connect your Roku player to your TV. Remember to tune your TV to the appropriate source/input depending on which one the Roku player is connected into.
