Question Three screens on mac mini


Novice Member
I currently use a mac mini with a presentation program. There is a monitor connected via hdmi that is at the desk with the mini and I am sending a second signal via displayport to vga to the presentation television. I need to basically extend my first monitor and have a second screen at the desk. I know these only support two signal outputs but i have heard of someone using a USB to HDMI adapter to "trick" the mac into having a third display. Is this a viable option? I was shown this

Yes, this is usually a dock and connects to the Mac via a standard USB2/3 cable. The dock then has at least one monitor port, usually HDMI or VGA or DisplayPort (latest dock models). You then install a driver on the Mac - and then you have a total of 4 monitors.

DisplayLink is the company which pioneered such a technique with hardware and software and Dell, Targus, HP, have their names on these docks.
