Executive Overview
Computer video signals have continued to evolve over the last several decades during which an
enterprise reference to the “computer” shifted from mostly mainframe and larger “minicomputers” to
the distributed client-server model that prevails today. In parallel, the TV has come a long way from the
small black and white consoles of the 50s to color to large screen TVs and now HDTV LCD TVs.
For data center administrators who are responsible for monitoring the screens of hundreds, and po-
tentially thousands, of servers and PCs, video resolution becomes paramount for effi ciency in the data
center or server room. One such tool to aid in this effort is the KVM (keyboard/video/mouse) switch
that enables IT professionals to easily and effectively manage servers and other network devices –
within the data center or from remote locations.
This white paper will offer a technical glimpse into the “whys” behind the “V” in KVM and the impor-
tance of video resolution. The paper will also offer a historical perspective on video signals and chart
the continuum to high video resolution resident in the KVM products of today.
