The main consideration when selecting a VDU (or monitor) for a computer is whether the display is monochrome or colour. Monochrome monitors are cheaper than colour monitors and are suited mainly to showing text and high-resolution CAD and desktop publishing applications where a single colour is adequate. Colour monitors are the most common these days, and can display colour drawings, multi-layer CAD drawings and graphics-based software.

The higher the resolution, the better the definition and the more expensive the monitor! As well, a monitor must match the video driver card inside the computer.
