Digital Visual Interface
Digital Visual Interface (DVI) enables you to connect your computer to displays such as at-panel monitors, projectors, and so on.
There are three types of DVI connections:
• DVI-D (DVI-Digital)—DVI-D transmits digital video‑signals between the video card and the digital display. This provides fast and high-
quality video output.
• DVI-A (DVI-Analog)—DVI‑A transmits analog video‑signals to an analog display such as a CRT monitor or an analog LCD monitor.
• DVI- I (DVI-Integrated)—DVI-I is an integrated connector that can transmit a digital or an analog signal. This port is more versatile as it
can be used in both digital and analog connections.
DisplayPort
DisplayPort provides digital connection between your computer and display devices such as monitors, projectors, and so on. It supports
both video and audio signals. DisplayPort was designed specically to be used with computer displays.
Mini DisplayPort
Mini DisplayPort is a smaller version of the DisplayPort.
NOTE
: DisplayPort and Mini DisplayPort are compatible with each other but the ports and connectors vary in size. If the port
sizes are dierent, use a converter.
Advantages of DisplayPort
• Supports high resolutions and high refresh‑rates.
• Supports 3D transmission.
• Supports multiple display‑devices simultaneously
• Supports High-bandwidth Digital Content Protection (HDCP).
• Supports plug-and-play adapters that allow you to connect displays using older connection standards such as DVI, HDMI, and VGA.
• DisplayPort cables can extend up to 15 m (49.21 ft) without requiring signal boosters.
HDMI
High Denition Multimedia Interface (HDMI) provides digital connection between your computer, display devices, and other multi-media
devices. It supports both video and audio signals.
HDMI ports are commonly available on computers, TVs, set-top boxes, DVD and Blu-ray players, gaming consoles, and so on.
Advantages of HDMI
• Supports high resolutions and high refresh‑rates
• Supports 3D transmission
• Supports HDCP
