• All-in-one PCs: All-in-one PCs, notebook computers, handheld PCs, and other devices use a display screen as the display device.

• Video game systems: Video game systems use a display device to show the games output.

Output devices are essential components of a computer system, and they convert the computer data into human-understandable form.
