Why Network Administrators Should Explore the “V” in K-V-M Switches

-P07-

Use a lower bitmap of 800 x 600 or 1024 x 768 pixels even though the IP KVM may support higher •

resolutions

Try a lower refresh rate of 60 Hz instead of 65 to 80 Hz•

Lower the color depth setting the computer to 256 or thousands of colors instead of millions•

While IP KVM video over the Internet may take longer to appear and refresh than local video, it offers

a better option than driving across town or ﬂ ying to a destination to control the computers.

Select IP KVM systems can redraw the screen at a lower image resolution than what is generated from

the computer video cards. However, this consumes processing time and

To optimize the video signals over an IP KVM connection, the key is reducing the video quality settings

on the controlled computers:

KVM on a 4-pair Cat 5 or Cat 6 cable, only 2 conductors carry the outgoing video signal along with

keyboard and mouse components. The video, keyboard and mouse control are carried through DSL

or TV cable internet connections either of which uses just two

wires.

To perform this conversion from a relatively fast analog video format to a slower digital format, “frame

grabbing” is used in conjunction with various compression methods to reduce the amount of band-

width required to convey the video.
