If I buy a 16x9 wide screen TV, will I get rid of the black bars forever?
Nope.
You're wrong for assuming that a 16x9 set will completely eliminate the bars. The shape of your TV is 16x9. If you attempt to play any material that isn't 16x9 (either wider or narrower), without stretching or cutting off parts, there will have to be unused area (black bars).
A 16x9 set will perfectly contain some widescreen filmsand you will see them without bars. However, films with an aspect ratio of 2.35:1 (like Gladiator, Armageddon, T2, Harry Potter, etc) are wider than the 1.78:1 (16x9) TV frame. In order to present the film in the proper shape without cropping, a small amount of unused space will exist above/below the picture area.
You will have bars any time the content differs in size from the shape of your screen.
For example, to properly display 4:3 TV programming- there would be black bars to the right and left, this is just unused space because the program shape is different than your TV's shape. Some TVs offer a stretch mode which unnaturally elongates the 4:3 picture to the width of your set-- however without stretching it, the picture would be less wide than your set (resulting in unused picture on the sides).
The same is true for Movies with a 2.35:1 aspect ratio. These films are wider than your 16x9 set, so you will still need small bars of unused space at the top and bottom in order to properly present the width of the material.
So, the basic answer is:
If the content is wider than your set (2.35:1 aspect films) you will have small bars at the top and bottom-- if it is narrower (like 4:3 normal TV programming)- you will have bars on the sides.
So, buying a 16x9 set doesn't eliminate black bars- it simply gives you a wider aspect set. If you watch only 16x9 (1.78:1) aspect material, you'd never see bars-- but since many films are wider, and most TV is narrower- you'll never completely eliminate them.
So, it's best to watch the program, not the bars.
