DisplayPort™ - Features and Benefits
Dell, in collaboration with a group of leading PC, graphics, and
semiconductor companies, has developed an open-standards based, royalty-
free, and extensible interface, DisplayPort, suited for both external desktop
monitors and internal display interfaces.
By consolidating the internal and external signaling methods, DisplayPort
enables the introduction of "direct drive" digital monitors, resulting in the
most efficient means possible for delivering flat panel display technology to
end users.
DisplayPort is also suitable for connectivity between high definition content
applications such as optical disc players, mobile devices, personal video
recorders, and TVs.
Other features include:
•Higher resolutions such as WQXGA (2048x1536 pixels).
•Variable color depth (up to 30 bits-per-pixel (bpp)).
•Up to 120Hz refresh rate.
•HDCP v1.3 support for viewing Blu-ray disc content.
•Support for cables up to 15m long.
•A single interface and cable that accommodates two-way audio and video for
systems with built-in or external speakers, microphone, and camera.
•Better performance than dual link DVI (10.6 Gbps vs. 9.6 Gbps)
•High-bandwidth audio.

NVIDIA SLI and ATI Crossfire Technologies

In some graphics configurations, two or more identical graphics cards can be
configured to enable NVIDIA SLI (Scalable Link Interface) or ATI Crossfire
technologies. Doing so can increase gaming and 3D application performance.
Detailed information about the benefits of using these technologies can be
found on the NVIDIA and ATI websites respectively.
