Ah-Ha....that’s not what you TV looks for. The picture on that will not be good-especially on a good TV.
I think what your system is looking for is access to the downloaded “apps” for the services you want to use.
I use a fire stick and I had to download the Apple TV, Netflix, and Hulu “apps” to the service. Only then could I watch them through the fire stick.
And, I had to download HBO/Max directly to my TV. There are resolution issues all around—but not relevant here.
I think the “problem” is the definition Roku is using for their interface. When I think media browser, I think of a “server.”
I would guess a quick search on Roku’s site for definitions would help you through this.
I have roku and a ton of apps. I get ustvgo.tv and pluto.tv beautifully on my tablets. But I would love the content and Choice on my main TV.
How if it is possible
