Why Network Administrators Should Explore the “V” in K-V-M Switches

KVM switches that are “DDC-ready” will pass the DDC data between monitor and computers – oth-

erwise, the DDC functionality that works on a direct PC-to-monitor connection will be disabled when

going through the “non DDC-aware” KVM.

Multiplatform Video

Microsoft Windows has long been the standard for many data processing environments, although Sun

Microsystems has carved a large niche and Apple’s Macintosh is on the rise again. Silicon Graphics

(SGI) made inroads into the data center with its high-powered graphics-intensive systems using a pro-

prietary video. One school of thought equated “multi-platform” with different types of video, but that

is not as prevalent except for DVI vs. VGA in limited areas.

Today’s Sun computers all have standard VGA connectivity which eliminates the need for an adaptor.

Ten years ago, Apple began shipping systems with VGA video out. In the last few years, Apple has

adopted DVI-I and includes an adaptor cable for users to connect its computers to standard VGA

monitors or KVM switch inputs.

Flat Panel Displays and KVM Switches – Words of Wisdom

In the past, a CRT delivered a sharp, clear image with a variety of incoming signals, making it an ex-

cellent choice for use with a KVM switch, particularly if the computers connected to the switch have

different video output settings.

The advent and mass acceptance of ﬂ at panel LCD is attributed to its ability to better display the pix-

els. Each pixel is controlled by a transistor that causes the liquid crystal next to it to become opaque

or transparent to light transmission. There is also a backlight within the screen. Energizing or de-ener-

gizing a given transistor twists the polarization of light by its liquid crystal and either allows or blocks

the backlight from reaching the viewer.
