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 and is basically is a miniaturized version of DisplayPort. 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]. In fact the Mini DisplayPort connector can be adapted to support a VGA, DVI, or HDMI interface. Mini DisplayPort uses a smaller connector than DVI, so thin notebooks benefit from the new connector. The Mini-DisplayPort connector is only about a third the size of the DVI connector.
Mini DisplayPort is [was] 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.

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.
HDMI [High Definition Multimedia Interface]
describes the video interface for consumer Audio Visual entertainment equipment
SVGA [Super VGA] offers more colors and
resolutions than normal VGA. However the term VGA is used to describe either VGA or SVGA.
In addition to DisplayPort, these are the primary video standards.
