Review on StarTech.com USB Powered Dual Port VGA KVM Switch - 2 Port USB VGA Cable KVM Switch with Remote Switch (SV211USB), Black by Ian Krump

I liked this thing at first - it worked perfectly with my PCs, switching between them was fast and the picture quality was perfect. After about 5 months of use, one of the inputs stopped working properly. There is a little hissing noise at the bottom of the screen, the signal drops randomly every few minutes causing Windows to temporarily lose the monitor. I've tried swapping which HDMI cable is connected to which computer to make sure the problem isn't with one of my computers and the problem is with one of the KVM cables - so definitely a defective device.
