This is my second of Uniclass KVM. The connection is very easy, no driver, connect a power supply VGA cable purely, PC and running. I have chosen this KVM because here can easily connect the new USB keyboards. This also works fine. Since I already had other brands in use can draw a direct comparison and here's the best Uniclass. Of course there are also KVMŽs for 400, - / 1000, - these are certainly better for the professional sector. For private and semi-professional range is the Uniclass ideal. I run in total 7 PCŽs and 4 on the Uniclass KVM -. Bislnag no problems with the systems Linux, Win XP, Win Vista 64, Win 7 64th A failure I've recorded with a Win 7 64, which is not recognized by a merh WIN update. The problem I have to clarify with Uniclass - I start from a WIN / video card driver problem.
