Hi @geto25,
Welcome to the Roku Community, and thanks for the inquiry.
Here are a few things that you can take note of. Roku streaming devices run different software. So when connected to a TV, automatically, the TV will work as a display, and the processor will be your Roku streaming device. All features, accessibility, and functionality can be accessed and navigated directly to the device and not on the TV. But there are some inputs that need to navigate directly to the TV. It seems like a lot of information, but you can visit our Support page here: How to set up your Roku Ultra.
Hope this answers your query.
Thanks,
Rey
