VDUExample: "A digital projector is often used as a VDU for PowerPoint presentations." A VDU is a Visual Display Unit. It is another term for monitor or screen, but may also refer to a projector or other type of display. VDUs may be peripheral devices or may be integrated into a computer system. While early VDUs were mainly CRT displays, today most monitors are flat panel displays that use LCD or LED technology. Updated: October 29, 2009 |
