Hi denise58,
Welcome to the Roku Community!
Thanks for showing interest in our Roku devices! We're happy to assist. You will need a distinct Roku device for each TV. It is not possible to utilize a single Roku device on numerous TVs at the same time. You may, however, disconnect your Roku from the TV you're currently using and use it with another TV as long as the new TV is connected to the same Wi-Fi network. We suggest visiting our website for more information about our devices. Please click here.
If there's anything else that we can do to help you, please feel free to post.
All the best,
John
