I used it to split my Dell G-Sync monitor, Razer USB headset, keyboard and mouse between gaming PC and MacBook. I can confirm it supports G-Sync 2560 x 1440 @ 144Hz You are using the mouse port to connect the mouse, the dpi and mouse movement will NOT be what you expect. However, if you use 2 other USB ports (2 not for keyboard and mouse) it works fine. The reason I'm bringing it back is sometimes (quite often actually) if you switch your USB device back and forth it might stop working. recognized by the PC. And you need to switch to another port or restart KVM. Removing the USB headset does not help.
