Appendix C: Getting Peak Performance

Choose the best video mode

•We recommend using 60Hz refresh rate and 1024x768 resolution. Using a smaller resolution like this allows you to fit multiple windows on your remote desktop. Higher refresh rates stress the video card's quality and do not provide any additional information or benefit.

Noisy video cards

•A digital KVM works by converting the analog video signals emitted by your video card into digital data. If there is noise on that signal, then it must be digitized and sent over the network too. The name brand, quality video cards have, in our experience, better performance simply because they don't add analog noise.

•Some external KVM switches generate video noise too. Try to keep cables short to reduce the effect.

•Enable the Noise Filter option (on the Video Tuning menu) to mitigate noise issues.

Network performance

•The Server Remote Control will always send as much data as it can, given what's happening on the screen and the actual network performance. When nothing is changing on the video screen, zero bytes are sent over the network. If the whole screen is changing, then the module will send as much data as your network connection and VNC client can handle while not allowing it to fall behind.

•Network latency, which is the total time it takes for a packet to get to the KVM and come back, has the biggest impact on perceived performance and usability. Network bandwidth has a lesser effect, particular when just moving the mouse around. Only a few bytes need to be sent when the mouse is moving (and nothing else is changing on the screen), but the round- trip-time limits the hand-eye coordination of the user if it is too great. Both actual bandwidth and measured network latency are shown in the Main Menu.
