I have dual monitors, each with two inputs (HDMI and DisplayPort). I have two laptops, one with two HDMI outputs and the other with two DisplayPort outputs. I have both laptops outputs connected to my dual monitors' inputs at the same time, but I have to unplug the outputs from one laptop when I want to let the other laptop use the monitors. I need a switch with four inputs (two HDMI and two DisplayPort) and two outputs (either HDMA or DisplayPort) and a button that I can press that decides which laptop is to control the monitors. I have not been successful in my online searches and figured I should post in a forum and see what advice other folks may have. I'm not looking to spend more than $150. Thanks for any help!
