A fullscreen may refer to any of the following:

1. A full screen is any object or window that occupies the whole computer screen, covering up anything in the background. When a window is not fullscreen, it is known as a window. If the program and operating system support the ability for a window to be full screen, click the maximize button to make the window occupy the entire screen.

What is window fullscreen?

More commonly referred to as maximized, window fullscreen is any window or program that is using the entire screen but is still a window. With computer games, it's not uncommon for the game to have both a fullscreen (borderless fullscreen) and window fullscreen mode. When running a game in window fullscreen mode, you may notice a performance increase and be able to switch between other programs quicker.

How to enter and exit fullscreen mode

In a browser, you can enter fullscreen mode by pressing the F11 key on the keyboard. In other programs, the keyboard key or options to enter fullscreen mode van vary depending on the program. A game or other program that supports fullscreen mode has display options or settings that allow you to specify if you want to run it in fullscreen mode.

To exit out of fullscreen in most programs, you can press the Esc on the keyboard. When in an Internet browser, you can press the F11 function key to enter and exit from a fullscreen.

Should I use "fullscreen," "full screen," or "full-screen" in my writing?

As an adjective or when describing a mode or setting "fullscreen" or "full-screen" should be used. As a noun or when describing anything that is occupying the entire display or screen, "full screen" should be used.

2. The fullscreen format is a display format that modifies the original movie to fit the aspect ratio of your TV or another display. When a movie is displayed in the full screen format, a notice is shown indicating that the movie is formatted to fit your screen. During this formatting process, the edges of the movie are trimmed, allowing it to fit on your screen. In this format, the film is not displayed how the director originally intended it to be viewed.
