I have two monitors. So 2 of them came out. Use 1 for kybd/mouse + 1 mon and 2nd for another monitor. 5V USB power adapter connected to ph:850mA cellular adapter, otherwise switching was unstable. You have a mac kybd so 2*ctrl + [1,2,3,4] on the 1st switch works. I shift the 2nd manually. Sometimes monitors respond with a 2-4 second delay, but that's not a problem. Switching between Mac, PC and Linux works flawlessly. There are 2 monitors LG 32 inches 1920x1080. The resolution is suitable for everyday use. The only problem I've encountered is that when I put the computer to sleep it doesn't wake up to kybd/mouse.
