Did you really think we were done with DVI cable talk just yet? Well you’re wrong! We’re not through by a long shot. So far we’ve discussed what DVI is and the type of DVI technology that is out there. We’ve discussed the various connector types of DVI and the accessories related to DVI related tasks. It’s amazing what we haven’t covered yet considering what we actually have covered! Well let’s wait no further and get down to talking about our next DVI cable related subject.
For our DVI cables there exists single link and dual link technologies. They both exist in DVI-D and DVI-I connector types. With DVI-D and DVI-I cables information is sent via TMDS in long hand this is known as transition minizmied differential signaling. With single link one TMDS 165Mhz transmitter is used.
Dual link on the other hands needs two to work. The pins on a dual link DVI double the power of transmission and provide an increase in the efficiency of speed and signal. For example a DVI single linked 60-hz LCD can display a quality of 1900 X 1200 pixels. Dual link on the other hand can put out a display resolution of pixels that equal out to be 2560 x 1600. A most impressive number.
Entering the world of digital video technology is a simple step with the acquiring a DVI digital cable. The single link DVI cable is the most basic of these cables. It is the gateway from your video card to an LCD flatpanel or whatever digital display you are using. Single link cables however lack the same power or potential as its dual link counterpart.
On the positive side of things a single-link DVI cable is an uncomplicated and inexpensive way to get a digital display picture quality. This cable is usually included as a throw-in with DVD players and certain graphics cards. They provide the very minimum to enjoy a quality display.
Singe-link DVI cables are not as common to buy new as they once were. This because there’s only a marginal increase of production cost to manufacture dual link cables and because the connectors on both single and dual link are compatible. In many cases it’s best to use a dual link if the option is available.
The 1142 series DVI-D cable is a dual-link, DVI-D to DVI-D digital video monitor cable.
In constrast to single link DVI cables, dual link cables have a great pinset on their connectors. This allows for greater bandwith. This enables a better screen quality at greater lengths without quality drop-off.
HDTV, Plasma and LCD digital displays are more versatile in regards to the DVI standard. Dual-link cables allow for the highest quality of video display from your source. The use of high-bandwith digital content hardware is also taken into account with dual link cabling.
The connectors on a dual link cable are both DVI-D. has male DVI-D. These connectors allow for the highest quality of video display. However if you are not using fully digital equipment DVI-I and DVI-A are suitable alternatives.
