Connection and Video Properties
Dominion KSX's dynamic video compression algorithms maintain KVM console usability under varying bandwidth
constraints. Unlike competitive solutions, Dominion KSX optimizes its KVM output for not only LAN utilization,
but also via the WAN and dial-up. By dynamically adjusting color depth and limiting video output, Dominion KSX
offers the optimal balance between video quality and system responsiveness in any bandwidth constraint.
Power users of RRC should understand the following adjustable parameters in the Connection Properties and
Video Settings dialog boxes, and familiarize themselves with the effects of each setting – in different operating
environments, they can be optimized to your requirements.

Connection Speed
The Connection Speed selection box allows users to manually constrain Dominion KSX from using more than a
designated amount of network bandwidth. While Dominion KSX normally detects available bandwidth
automatically , users can use the Connection Speed setting to manually inform Dominion KSX of a bandwidth
constraint – whereby Dominion KSX adapts its behavior and simply refrains from even attempting to consume more
than the available bandwidth.
Color Depth
For most administrative tasks (server monitoring, reconfiguring, etc.), server administrators do not require the full
24-bit or 32-bit color spectrum made available by most modern video graphics cards. Attempting to transmit such
high color depths, then, would waste an enormous amount of precious network bandwidth.

Instead, Dominion KSX can dynamically adapt the color depth transmitted to remote users, in order to maximize
usability in all bandwidth constraints.

Progressive Update option: The extremely innovative Dominion KSX feature of Progressive Update can
enormously increase usability in constrained bandwidth environments. When Progressive Update is enabled,
Dominion KSX first sends an image of the remote desktop at lower color depths, and then provides higher color
depth images as bandwidth allows.

This option is very similar in philosophy as the common World Wide Web notion of "interlaced GIF" files.
Note: When Color Depth is set to Auto Select Color (default), Progressive Update is automated.
Dominion KSX will enable/disable Progressive Update as needed, disabling it for fast connections
and enabling it for slow connections.
