Scene 2. iMac screen turns black continuously no matter how many times you restart it.

Scene 3. When you are doing something on Mac, for example, watching a movie, the screen goes black suddenly, but the system runs still in the background.

Overscan

Overscan refers to a cropped image on your TV screen. Here are some examples:

A setting on your TV zooms in on movie content, so that you can't see the outermost edges of the film.
Your TV's plastic border blocks some of the TV screen, so that you can't see the edges of the content.

Underscan

Underscan is usually intended, and refers to black bars that appear around a movie or show. The bars appear because the content was filmed in a different proportion than your TV screen. Here are some examples:

Black bars appear above and below a movie because it has a wider aspect ratio than your TV screen.
Black bars appear left and right of a TV show, because it has a smaller aspect ratio than your TV screen.
