People, by watching others do stuff on the screen, kind of feel their company.
It depends what type of screen you're watching it on ! A 'standard' TV set uses 4:3 ratio. A wide-screen model uses 16:9 ratio.
Even though wide screen is superior, there are still some people who don't like the black bars, especially if they're watching on older televisions.
TVs are usually sold in inches or centimeters (the diagonal measurement of the screen size).
Most often on the bottom right side of the video there will be a box that represents a tv screen. It may have arrows at the corners. Click on that.
Use the ASPECT button on the remote to make the picture fill the screen. This will not always work. The program was made in the wide screen format and not necessarily made for the aspect of your TV screen.
People who have Monochromacy are only able to see in shades of grey, much like watching a black and white television screen.
