Summary: I am having serious issues with this switch, my PNY 8600 GT, and 64 bit OS. Video does not work on that PC. Plug video card directly to the monitor it works great. Plug the card to the KVM no video. Same configuration was working great for years with XP, then Vista 32.
Pros: It was a really good switch. Used it for years without issue.
Cons: Does not appear to work with my video card and 64 bit OS (Vista and 7)
Summary: I was just a little upset that my mouse was only found as a generic 2 3 or 5 button wheel mouse, but when I tried to play UT2k4 it kept making me strafe left or backwards. My old 2 port KVM was and is way better.
Pros: Audio and 4 ports
Cons: It don't recognize my mouse though it. Makes me walk either left or backward in games. Seems slow at responding to keystrokes and mouse clicks. You can type and see the letters show up after and not while you type.
