The DisplayPort Video Interface released in 2007 and 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 DisplayPort Video bus supports 1, 2
or 4 lanes, with 4 lanes transferring 10.8Gbps, or 2.7Gbps rate per lane
[pair].
The DisplayPort Video 1.0 Interface provides 2x the performance of DVI.
The maximum cable length of the DisplayPort Video cable is 15 meters
long.
DisplayPort is being produced to replace the DVI interface and the VGA
interface [SVGA and others]. DisplayPort uses a smaller connector than DVI, so thin notebooks benefit from the new 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.
