The world of digital video begins with a DVI digital cable, and the
single-link DVI cable is the standard entry. This DVI cable is an
effective bridge between your computer graphics card and an LCD flatpanel
or other digital-compatible display, suitable for most situations.
The single-link DVI cable is a simple and economical solution to digital display
connectivity. These DVI cables offer the basic throughput necessary
to carry an all-digital video signal from source to destination, and are the minimum
requirement for connecting two DVI devices.
However, they are not the ideal solution. Single-Link cables have limited resolution
and are often perceived to be the budget-conscious alternative to a 'standard' DVI
cable, which is a Dual-Link DVI cable.
Dual-Link cables, with all their pins connected, offer twice
the throughput of data, and are recommended for use with computer monitors 30" or larger as
well as for resolutions higher than 1900x1600.
