Distribution amplifiers are used in applications that require multiple projectors or monitors to display the same source's image at the same time. For example, with a distribution amplifier, the single video output on most computers can be converted to two, four, or more outputs.

The above is an example of how a DA can be used. In the diagram, a computer with a digital video output is being input to a distribution amplifier (D/2 DA4 DVI). The DA is splitting the signal and distributing it through four, independently buffered outputs: a computer monitor, a digital monitor, and two digital projectors.

When more outputs are needed than are available on a single DA, multiple DAs can be looped together. That means the output of one DA can be fed into the input of another to form a daisy chain.
