Well not simultaneously of course, but you know how there's the ability to have multiple input peripherals through the same...serial port? Is it possible to have multiple output (monitor specifically) into one output? I'm imagining a device where I just turn the knob and it flips between two computers' visual outputs. If such a thing existed it would make my life 0.00000002% (approx) more easier. As for my computer time, it would improve my productivity quite a bit, because every time I remove my monitor plug I risk hanging my machine
