Technically working. And I can't say exactly how big the problem was compared to my computers. But I have a gaming tower computer that is 7 years old and a laptop that is about 2 years old. If a tower or laptop dock is enabled but not selected as an input, the switch will not work to subsequently identify them. Also, the mouse and keyboard buttons I have connected work for a while and then stop working and essentially have to reconnect. There should have been a 20-second pause between actually continuing to type or click/move the mouse. It also only supports HDMI, which I was aware of prior to buying, but this meant I couldn't choose which monitor I used it on (I have two of them) as one of the monitors only has an HDMI Monitor cable supported (tilted only). with one side). and it will not support it.
