Mac – Connecting two HDMI monitors to Late 2012 Mac mini

Alot depends on what Mac Mini you have. Early Mac Minis only had a single DVI out, later versions had mini DVI out, still newer versions had a mini DVI and a mini DisplayPort out, and the newest all metal version has a mini DisplayPort and HDMI out and comes with an HDMI to DVI adapter.

Negrino was correct in saying that you could get a USB to DVI adapter but you might only have to get one of them, depending on your Mac Mini's video out ports. If you have an early G4 or Core Solo Mini, you would have to get 2 adapters.

For a little clarification, are you planning on mirroring your desktop 3 times or having 1 desktop extended over 3 monitors? If it is the first option then you could simply get a VGA or DVI Y adapter that would mirror the image coming out of one port to 2 or more monitors.

It is able to do so, I'm doing this exact thing right now. I've got two 1080p monitors connected, one via HDMI (to DVI), one via Thunderbolt (also to DVI) - works all fine :-)
