The standard ratio of TV is 4:3, and the widescreen is 16: 10, so playing TV with broadband will definitely be stretched and deformed.

However, most TVs provide the function of forcibly locking the aspect ratio. Although there will be more black edges on the left and right after use, the characters will not be deformed.

The latest TV also provides intelligent stretching function, which stretches different parts in different proportions according to the principle that the concentrated observation area of human eyes decreases from the center to both sides. So the picture distortion is not obvious.
