Display Connectors: DVI-D, DVI-I, DVI-A & Display Ports

Today’s lesson covers the connector types that allow us to transfer video between our computer or display device.  We begin with DVI.

The DVI connector comes in several types and we diagram to demonstrate to the differences between each type.  For example, DVI-a only transfers Analog, where DVI-D only transfer Digital signals, and the DVI-I transfer both.

From the diagrams you’ll be able to distinguish between the Analog and Digital type, discuss how each device transmits its signal, and articulate the benefits of the DVI-I (integrated) cable connector.

The display port connector is a 20-pin connector that resembles an HDMI connector but transmits fewer signals.  We’ll discuss what its function is, why it would be used, and how it works to transmit its signal type.
