SERVSWITCH™ BRAND FIBER KVM EXTENDERS

6.2 Making Video Adjustments with the Remote Module’s User Controls

If the image from your computer that’s displayed on the remote monitor is badly distorted, this might be the result of a video-signaling problem. Refer to Chapter 3 (especially Section 3.2.1) or Chapter 4 for ways in which you can modify the way the ServSwitch Brand Fiber KVM Extenders handle the sync and color signals.

If the image is not distorted but the colors are off, we first suggest that you try tweaking the contrast and brightness dials on the rear panel of the ServSwitch Brand Fiber KVM Extender’s Remote Module. Once you get the image as close as you can to how it should look, try adjusting the image with the monitor’s controls.

If this doesn’t work, you might try disabling the Extenders’ automatic gain control (see Sections 3.2.2 and 3.3.2 for the ACS235A PC model or Sections 4.1.2 and 4.2.1 for the ACS236A Sun model), then using a tiny screwdriver to turn any of the three gain-control screwdials with which you can manually control the gain of the red, green, and blue color signals. These are also on the rear panel of the Remote Module: Each screwdial is just above and to the left of the fiberoptic connector carrying the color signal it controls, so the red screwdial is next to the red connector, green next to green, and blue next to blue. Be careful if you do this; when you make manual adjustments like these, it’s very easy to throw the color of your monitor display entirely out of whack.
