How to remove the channel identification, volume bar and mute icon from the screen of my Philips TV?

The TV does not have an option on the TV menu to remove the channel identification and [Mute] icon display from the screen.

The volume bar can be permanently removed from the screen in the [Setup menu] -> [Installation] -> [Preferences] -> [Volume bar] -> [OFF].

You can also minimize the display to the top left corner of the screen.
