user interface on the TV

Hello. I recently met Volumio. I have Led TV. (resolution 1920X1080) I want to see a user interface on the TV. Connect the HDMI output of raspberry to the TV. Installed the plugin “touch display” interface does not appear. The screen has a gray background and a mouse pointer. Help advice. how to activate the user interface.
Thank you in advance.

I think you misunderstand how Volumio works; it’s a ‘headless’ player, meaning it has no native interface of it’s own. Instead, it presents a web page as the interface/control surface. If your TV can access web-pages, then you need simply aim it at the Volumio player and your wish is fulfilled,
