Overclockers Online has published a new review on the Startech.com SV411KA KVM

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.
