Technically Speaking

Digital Visual Interface (DVI).

The Digital Visual Interface (DVI) video standard is based on

transition-minimized differential signaling (TMDS). In a typical

single-line digital signal, voltage is raised to a high level and

decreased to a low level to create transitions that convey data.

To minimize the number of transitions needed to transfer data,

TMDS uses a pair of signal wires. When one wire goes to a high-

voltage state, the other goes to a low-voltage state. This balance

increases the data-transfer rate and improves accuracy.

Although there are four types of DVI connectors, only DVI-D

and DVI-I are commonly used for monitors. DVI-D is a digital-

only connector. DVI-I supports both digital and analog RGB

connections.

According to a survey by Data Communi cations magazine,

90% of network managers surveyed say that getting the techni-

cal support they need is extremely important when choosing a

vendor. But even though network managers pay anywhere from

10 to 20% of their overall purchase price for a basic service and

support contract, the technical support and service they receive

falls far short of their expectations—and certainly isn’t worth

what they paid.
