External monitor to iMac

Awsmits · 06-26-2019, 01:14 PM

Hi, I have a 2012 27" iMac that I love, running El Capitan (10.11.6) and I wish to connect a single external monitor (VGA and DVI inputs) to it. I thought I could just use one of the two Thunderbolt ports, but System Info says they are not working, so I would like to use one of the 4 USB ports to connect to the external monitor. Can you recommend the best one, and what drivers/software I need?
