Hi, @Taverett.
Greetings from the Roku Community!
We appreciate you reaching us about this. We're here to help.
You may use a Roku streaming device on your new TV, however, it will still depend on you if you want to replace it with a Roku TV.
If there's anything else we can do to assist you, please let us know. We're always willing to help.
Thanks,
The Roku Community Team
