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.
@sw1 Thanks for the question. You will need to have a Roku device connected to each TV in order to watch streaming content via Roku. You can either move your existing device between each TV, or purchase a second Roku device to have access to streaming on both TVs simultaneously.
To add to what Tanner said. If you buy a TCL Roku TV, then no you don't require an additional Roku player, as the TV has Roku built into it.
It is possible to watch the same content on two different TVs, but that requires an HDMI splitter and running a cable to both TVs. These splitters can be problematic, so it's really wiser to use a separate Roku player on each TV. More than likely, less expensive as well.
There's no restriction on how many Roku devices you can register on your Roku account, and Roku does not charge a fee for registration or accounts. Beware of some scam web sites that try to sell you something.
Also, if you have multiple Roku devices on the same account, they will all have the same channels installed automatically. Remove a channel from one device and it's removed from all. Same with a new channel installation. They can be used independently, but the channels will match. If you prefer having different channels on different players, you need separate Roku accounts for each player. Again, no cost, but you need a different email address for each account.
