SERVMANAGERS
The ServManager will support SVGA (Super VGA) video, but with the original
Serv cables for IBM PC applications, the video quality will decrease markedly
at higher resolutions and distances. Table 4-2, below, illustrates this. The
distances in the table are total cable lengths measured from the CPU to the
monitor. The table assumes that one ServManager is between the CPU and
monitor; in a cascaded application with a ServManager and a submaster
between the CPU and monitor, video quality will always be lower.
