I believe you are referring to the display volume indication bar, correct? Most Samsung TVs have the volume displayed vertically on the left side of the screen. LGs have a circular volume display on the lower left or right side. I'm not sure about other manufacturers.
I saw one in the store but I forgot who the manufactuered it.
The volume control is on the left side and it goes from north to south instead on the bottom from east to west.
This makes it easy to change the volume and does not interfere with the closed caption when the volume needs to be adjusted.
