SERVSWITCH™
4.1.3 M
ONITOR
NOTE
At resolutions up to 800 x 600, the video quality for most ServSwitch
applications will be excellent. At higher resolutions, however, you might
see a little fuzziness on your monitor no matter how close to ideal your
ServSwitch system is.
If all of your CPUs are of the same type, we recommend that you use the
corresponding type of monitor. If your CPUs are of different types, the monitor
must be a multisync model, able to sync to every CPU’s video-output frequencies,
and compatible with all of the CPUs’ video cards.
For maximum compatibility, we recommend a 17" or larger, high-quality
multisync monitor capable of displaying a maximum resolution of not less than
1280 x 1024 at a maximum refresh rate of not less than 75 Hz. The NEC Multisync
5SG is one such monitor, and others are available from NEC, Sony
®
, CTX
®
, etc.
The higher the resolution you use, the less distance you can run; see Tables 4-2
and 4-3 on the following pages.
The ServSwitch is designed to support standard VGA video, including VGA
monochrome (“page white”). It does not support PCs that use CGA, EGA, or
proprietary versions of VGA that depart from the original specifications. Consult
your PC’s manual, and if that doesn’t tell you whether or not the PC uses standard
VGA, consult with the PC’s or the video card’s manufacturer.
The ServSwitch is also designed to support SVGA, although it doesn’t handle
higher resolutions or longer distances very well without coaxial cabling (see the
next two pages). With coaxial cables, it will also support XGA, RS/6000, and SGI
video (RS/6000 and SGI require cables with 13W3 connectors—see Appendix B).
