This is the first DVI KVM I have owned, and it is also the first KVM I've owned that I have been 100% happy with. I've always encountered problems with the video of some sort. There has always been some type of flicker or horizontal placement issue when viewing any port other than #1 on any of my old KVM's. None of that with IOGear's 4-port DVI KVM, all computers look sharp on my Samsung 19 widescreen LCD. I'm also using the KVM with a USB multimedia keyboard and 5 button mouse, everything works great! The cables supplied with the KVM are top quality as well. There is a good weight to the unit which helps keep it in place. I have not had one issue with the device locking up and needing to be reset (which is nice because it is hidden under my desk out of view). I'm using a set of Infinity bookshelf speakers connected to an old Sony amplifier for sound out of the KVM. Audio sounds perfect out of any port on the KVM with no distortion whatsoever. I can't comment on the firmware port or USB sharing because I haven't used them, but I have no concerns when it comes time to from what I've seen thus far. Finally a KVM that works the way I wanted! Thanks IOGear!
