Quote: A four port KVM switch that also has the ability to distribute audio
and a microphone across four computers in or out of the OS can be the
ultimate tool for those of us with multiple systems. With a quality KVM like
the SV411KA there is absolutely no lag whatsoever. I was worried that mouse
lag or stuttering would show up with all three machines on but it certainly
didn't. Even at 1600x1200 the display kept up 100% when gaming and watching
movies. The other huge benefit to using this KVM over VNC is the ability to
switch between computers outside of Windows allowing me to jump into the
BIOS of any of the three machines without swapping a single cable; this is
priceless for an overclocker.
