I thought it wasn't working properly but before I gave up I swapped input and output and it worked great. Not sure how to define input and output, so keep an open mind. But I'm using this to share a keyboard for my home computer and my work laptop. I have another splitter that allows me to use the same 32 inch screen for my home computer and work laptop. Push two switches to go from home to work. Perfect for those of us who work from home.
