Connecting Dell Laptop to iMac and Dell Monitor to have three monitors
I am going to be working remote, and wanted to know if there is a way to connect my Dell Latitude 7480 up to my 2011 21.5" iMac and Dell monitor at home.
Currently, I have my iMac 2011 at home connected to a Dell monitor using Thunderbolt to VGA cable. I want to to hook up my Latitude 7480 into that current setup, so that I may use the Dell laptop as the main screen, and my other two monitors at home as monitor displays. The iMac 2011 has four usb ports and one thunderbolt port. I currently have the thunderbolt-vga adapter plugged into the Dell monitor at home to use it as an extended monitor.
