A computer display monitor, usually called simply a monitor, is a piece of electrical equipment which displays viewable images generated by a computer.
Screen size is measured as the distance from the bottom left corner to the top right corner. The actual viewing distance is slightly smaller than this. Most modern computers are supplied with a 17-inch monitor. A 19-inch or 21-inch large display monitor may be useful to view large print if a person has a vision impairment.

Monitors should generally be positioned no greater than an arms length from the user with the eyes resting in approximately the top third of the screen (standard screens). The monitor should be positioned directly in front of the user to minimise the need to rotate either the neck or lower back to work for sustained periods:
