Warmest welcome here in the Roku Community, @Cool182!
Thank you for contacting us regarding the use of a remote control to operate your TV. We'd be happy to provide further information about this.
Before proceeding, may we know what specific Roku streaming player is connected to your Vizio TV? Please be informed that you need to use and pair the Roku remote that comes with your Roku player successfully to navigate to your Home screen.
You can use your Vizio remote to select the HDMI input where you plugged in your Roku player. However, you need to use your Roku remote to operate your TV screen.
We hope this information is helpful. Please let us know if you need further clarification.
Best regards,
Carly
