36 D OMINION KSX U SER M ANUAL
Analog-to-Digital Settings
The following parameters are best left to Dominion KSX to automatically detect (on the RRC Menu Bar, select
Video > Auto-sense Video Settings), but a brief description of each is included here.
• PLL Settings: If the video image looks extremely blurry or unfocused, the PLL Settings for clock and phase
can be adjusted until a better image appears on the active Target Server.
-
Clock: Horizontal sync divider to produce pixel clock. Controls how quickly video pixels are displayed
across the video screen. Changes made to clock settings cause the video image to stretch or shrink
horizontally. Odd number settings are recommended.
- Phase: Phase values range from 0 to 31 and will wrap around. Stop at the phase value that results in the
best video image for the active Target Server.
• Color Settings: Gain control can be thought of as contrast adjustment. Offset control can be thought of as
brightness adjustment.
-
Red Gain: Controls the amplification of the red signal.
- Red Offset: Controls the bias of the red signal.
- Green Gain: Controls the amplification of the green signal.
- Green Offset: Controls the bias of the green signal.
- Blue Gain: Controls the amplification of the blue signal.
- Blue Offset: Controls the bias of the blue signal.
- Link Color Controls: Makes all the gain slide adjusters move in unison when any one color’s gain slide is
moved and all the offset slide adjusters move in unison when any one color’s offset slide is moved.
• Sense video mode changes automatically: Determines whether Dominion KSX will automatically update the
video image being sent RRC each time it detects a change in video resolution or refresh rates at the Target
Server.
Color Calibration
Automatic Color Calibration adjusts the color settings on Dominion KSX to reduce excess color noise and data
during digitization of video images. This data streamlining will increase the operational performance of Dominion
KSX, particular color accuracy.
A very simple procedure to execute, Color Calibration should be performed if the color levels (hue, brightness,
saturation) of transmitted video images do not seem accurate. Because Dominion KSX color settings remain static
and do not change when switching from one Target KVM Server to another, performing this Color Calibration
routine once on a single representational Target KVM Server will benefit all connected Target KVM Servers.
To Perform Color Calibration:
1. Open a remote KVM connection to any server running a graphical user interface.
2. Ensure that a solid white color covers approximately 15% or more of the target server's desktop. One simple
way to accomplish this is to open the Notepad application and maximize its window size.
3. On the RRC Menu Bar, select Video
→ Calibrate Color to perform the color calibration.
