Works fine with an Alienware PC and a System76 laptop, using Linux on both. The laptop had occasional problems detecting the monitor on a cold boot, but works fine with a reboot. Sound works fine. The switching is pretty fast. All buttons on my Razer Deathadder mouse work, including DPI changing (though I haven't tried controlling the mouse's LED colours). My keyboard is bog-standard with no extra keys, so I couldn't test media control buttons and the like.
