Earlier TV was a TV, just a television set. Yes, there where sets with some extra features, standalone speakers for example, but it was easy to pick your choice. Now you have a lot more options to take into consideration and a number of terms to learn.
Those wall mount TV’s sell more and more but are considerably more expensive. They are so thin, 2-5 inches, or 5-10 centimeters. The picture is completely flat and the set should be connected to digital systems. The number one reason to buy a wall TV mount is the fact that it doesn’t require any space on the floor. And these TV’s can also be connected to your computer.
