SERVSWITCH™

5.4.1.B Resolution

This item gives you maximum monitor-type flexibility by determining the resolution and refresh rate of the video signal that the ServSwitch sends to the shared monitor while the unit isn’t receiving any video from the CPU. The possible choices—all using 640 x 480 resolution—are “PC1” (60-Hz refresh rate—the factory default), “PC2” (72 Hz), and “PC3” (75 Hz).

To change the resolution/refresh rate, press [Enter] while “Resolution” is highlighted. An input box appears. Use the arrow keys to select the desired combination of resolution and refresh rate and hit [Enter]. The input box disappears and the new setting appears in the “Resolution” field.

5.4.1.C Screen Saver

The ServSwitch has a built-in screen saver that reduces the wear on your screen. When there has been no shared-keyboard or -mouse activity for the length of time specified in the “Screen saver time” field (see the next section), the screen saver turns on. You can blank the screen or choose one of three possible display patterns: “Fireflies” (the factory default), “Weaving,” or “Bounce.” Normal video is restored when any key on the shared keyboard is pressed or the shared mouse is moved. If you are not in an on-screen display menu, then the computer name (label) is also displayed as if you had just switched to a new computer. While the screen saver is on, all of the Serv unit’s “SELECT” LEDs (the left-hand red port LEDs) will be turned off.

To change the screen-saver setting, press [Enter] while “screen saver” is highlighted. A screen-saver input box appears. Use the arrow keys to select the desired screen saver and hit [Enter]. The input box disappears and the new setting appears in the “Screen saver” field.

If an access password has been set (see Section 5.5.2), this screen saver also appears when no user is logged in. The screen saver will remain on-screen, blocking view of any computer video, until a user enters the access password correctly.

5.4.1.D Screen-Saver Time

This item determines how long (in seconds) the ServSwitch waits for shared- keyboard or -mouse activity before turning on its screen saver. The factory-default value for this option is 600 seconds (10 minutes). To change the screen-saver time, press [Enter] while “Screen saver time” is highlighted. An “Input new value” box appears. Use the shared keyboard’s number keys to input a new number of seconds from 0 to 999, then hit [Enter]. The input box disappears and the new setting appears in the “Screen saver time” field.
