This switch features a VGA port and 2 USB ports that let you share the use of a monitor and 2 USB peripherals, such as a mouse and a keyboard, between 2 different computers. The plug-and-play design allows easy setup.
I purchased a new computer this last spring. It came with Windows 10. My old computer still worked fine, but the rest of the world was upgrading and moving forward, but my Windows Vista just didn't have the power or memory to keep up. Plus, it was taking Windows 7 or higher to be compatible with Windows 10. Meanwhile, I had years and years of files, photos, programs, stuff I used every day, but couldn't move to the new computer. So, every day, I would have to unplug most of the cables from one computer, and plug them into the other computer. I had never heard of a KVM Switch, of course, I had never been in this situation before. The KVM switch lets you run two computers at once, both using just one keyboard and one mouse. There is a small button on a six foot wire that attaches to the switch that allows you to place near you, so you can, at the touch of the button, go from one computer to the other. Great product! No more reaching around the backs of the computers plugging and unplugging!
