i bought the adapter and it came with a CD with display link software. i just downloaded the new software, looked identical to the last install and still nothing on the 3rd monitor.

do you know if my mac mini can even handle 3 monitors? thats what i am trying to achieve. the other two screens were plug and play through the HDMI on the mac and the other though a thunderbolt to HDMI adapter. i was hoping this USB to HDMI adapter would also just be plug and play
