SERVSWITCH™ JR. MP

4.1.3MONITOR

NOTE

No keyboard/video switch can provide perfect video. You will see at least a little fuzziness on your monitor no matter how close to ideal your ServSwitch Jr. MP system is.

While PC-type CPUs and VGA monitors normally use two separate leads to send/receive sync signals (one lead for horizontal sync and one for vertical sync), Mac CPUs/monitors normally send/receive a composite sync signal on a single lead. This means that either your monitor must be capable of accepting both H/V and composite-sync input, or you will have to attach a Mac Adapter for ServSwitch (our product code KV99MA) to the Mac in order to resynchronize its video-port output.

For maximum compatibility, we recommend a 17" or larger, high-quality multisync monitor capable of (a) displaying a maximum resolution of not less than 1280 x 1024 at a maximum refresh rate of not less than 75 Hz, and (b) accepting both relevant types of sync input (H/V and composite). Such monitors are available from many manufacturers.

The ServSwitch Jr. MP 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 Jr. MP is also designed to support SVGA, although we recommend coaxial cabling for this, especially for higher resolutions. With coaxial cables, the Switch will also support XGA.
