CHAPTER 3: RARITAN REMOTE CLIENT 27

Connection and Video Properties
Dominion KX’s dynamic video compression algorithms maintain KVM console usability under varying
bandwidth constraints. Dominion KX is unique in that it optimizes its KVM output for not only LAN
utilization, but also via the WAN and dial-up. It also adjusts color depth and can limit video output,
offering an 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.

Opens Modify Connection Properties dialog box to
manually adjust bandwidth-correlated options (Connection
Speed, Color Depth, etc.).
1. On the Connection menu, click Connection Properties. The Modify Connection window appears.

− Connection Speed: Use the Connection Speed setting to manually tell Dominion KX of
bandwidth constraints. Dominion KX can adapts its speed and not use more than the bandwidth
that is available. Dominion KX detects available bandwidth automatically, but you can adjust this
use.
− Color Depth: Dominion KX can dynamically adapt the color depth transmitted to remote users in
order to maximize usability in all bandwidth constraints.
Progressive Update option: Progressive Update can increase usability in constrained
bandwidth environments. When Progressive Update is enabled, Dominion KX first sends an
image of the remote desktop at lower color depths, and then provides higher color depth
images as bandwidth allows.
Important: 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.
Note: When Color Depth is set to Auto Select Color (default), Progressive Update is automated. Dominion
KX will enable/disable Progressive Update as needed, disabling it for fast connections and enabling it for
slow connections.
− Internet Flow Control: When using Dominion KX over an unpredictable public WAN
(particularly in international scenarios), checking the Internet Flow Control check box ensures
that packets transmitted by Dominion KX are received and reconstructed by RRC in the correct
order.
