Hi. Never had one, never used such.
Seems there is dozens of models and cannot discern which is convenient for me.
Am after ethernet connection, able to update its firmware, internet browsing and if possible, working on 5V from the TV USB port. Cannot find which models have such features. Roku customer support seems only for owners, not for sales.

And with so many models, I wonder if older-used and new RokuTVs have restricted built-in Roku features that will end non-upgradeable, weird operating systems, soon obsolescence.
Suggestions, please ?

 

Our older model, does not have volume buttons in the remote. You must use the TV remote in parallel. Our newer model does have volume buttons.

I so not use for the "4k" versions because my TVs are not 4k and the programming is not either.
