Mac Mini now has two ports, Mini display port and Mini DVI video out...
Can I run dual monitor with this?
From Mac mini tech specs:
Extended desktop and video mirroring: Simultaneously supports up to 1920 by 1200 pixels on a DVI or VGA display; up to 2560 by 1600 pixels on a dual-link DVI display using Mini DisplayPort to Dual-Link DVI Adapter (sold separately)
