Help getting started with Roku devices, including setup, connecting your device to your TV, linking a Roku device to your account at my.roku.com/link, adding channels, subscribing to services, and more.
If you want to use Rokus simultaneously on two TVs, then you need two Rokus. If one TV has been retired, or you are willing to move the Roku from one TV to the other between viewing sessions, then you'll be OK with one Roku. It's like a book. If you want to read it in the Den and on the Patio, you can either move one around, or get two.
Does this mean that if I have purchased a new tv since I set up Roku on my first TV, that I need to buy another Roku express at Best Buy or another store?
No. If your new Roku is linked to the same user account as the original, then any subscriptions you have through Roku will be available on the new Roku as well. As mentioned, providers that you have a direct subscription with, such as Prime Video, Netflix, etc., you can use the same credentials to log in regardless of the Roku user account.
And to perhaps cover a different scenario, if you have an existing Roku on a TV and you replace the TV (not the Roku), you simply connect your Roku to the new TV and use it without making any further changes.
