Mini DisplayPort Description

The Mini DisplayPort Video Interface was released in 2008. Apple uses the Mini Displayport standard as it's new video interface. The Mini DisplayPort contains the same pinout as the current DisplayPort specification, but the connector has been reduced in size. The Mini DisplayPort supports a QXGA monitor [2048 x 1536]. The 2048 x 1536 resolution requires 4 lanes of data [the maximum].

The electrical interface is LVDS. The Mini DisplayPort Video bus supports 1, 2 or 4 lanes, with 4 lanes transferring 10.8Gbps, or 2.7Gbps rate per lane [pair].

The Mini DisplayPort Video 1.0 Interface provides 2x the performance of DVI. The maximum cable length of the DisplayPort Video cable is 15 meters long.

Mini DisplayPort is being produced to replace the DVI interface and the VGA interface [SVGA and others]. Mini DisplayPort uses a smaller connector than DVI, so thin notebooks benefit from the new connector.

Mini DisplayPort is an Apply only standard, controlled by Apple, while DisplayPort is a Video Electronics Standards Association (VESA) specification. Mini DisplayPort is very similar to DisplayPort but uses a smaller connector.

Additional Personal Computer Video Interfaces

Refer to the main PC Video Monitor Bus page, or to the main PC Interface Bus page. Use the Buses icon at the bottom of the page to reach the top level index for all bus types. Use the Equipment icon at the bottom of the page to reach manufacturers of PC Monitors. A few other current Video standards are listed below, refer to the Monitor link above to see them all.

DVI [Digital Visual Interface]: DVI interfaces are currently in full production and can handle digital or analog signals.

FPDI [Flat Panel Display Interface] describes the electrical layer, logical layer, and connector interface between flat panel displays and display controllers in an integrated environment. Also FPDI-1, used with VGA and SVGA [800 x 600]. Followed by FPDI-2

HDMI [High Definition Multimedia Interface] describes the video interface for consumer Audio Visual entertainment equipment

SVGA [Super VGA] offers more colors and resolutions. The primary standard refers to the BIOS, and how the computer talks to the monitor. VESA Display Data Channel [DDC] is a VESA standard that defines how to read certain pins in a standard SVGA monitor to query the monitor's capabilities.

VMChannel [VESA Media Channel] describes a hardware interface for desktop multimedia systems. The VMChannel is a multiple master, multiple drop, clock synchronous interface designed for concurrent pixel data streams.
