video display unit (VDU)

Contributor(s): Shahid Sattar

A video display unit (VDU) consists of:

  • A computer output device that uses a cathode ray tube or other technology to present visual images
  • One or more input devices, such as a keyboard , a mouse , or both.

A synonym sometimes used in the United States is video display terminal ( VDT ). VDU seems to predominate elsewhere. The term is widely used in ergonomic discussions, guidelines, and standards related to worker safety and efficiency.

The "classic" VDU is the desktop display and keyboard. However, as personal computers and workstations become more portable and smaller in size, the safety and design guidelines for VDUs call for continuing reconsideration.

VDU ... isn't it an old (pre 1990s) term for monitors?

it's what Computer monitors were called back in the day, before monitors became so common.
