Does anybody have this working successfully? I have tried a Monoprice adapter: http://www.monoprice.com/products/p...=10428&cs_id=1042802&p_id=6904&seq=1&format=2 and Accell Adapter: http://www.amazon.com/Accell-UltraAV-B087B-002B-DisplayPort-Dual-Link/dp/B002ISVI3U and now are going to try a http://www.amazon.com/Kanex-MDPC30-DisplayPort-Adapter-Display/dp/B0045I85GY The issue is that it never really powers on the monitor. It tries, and the monitor turns on for a split second and then shuts off. It then waits about 20 seconds and tries again. THIS IS THE KICKER: I installed Windows 8 in a bootcamp partition, and the monitor works fine. There is something in OS X (Mountain Lion) that is not making this work. Does anybody have any ideas? The adapter hooks up into the Thunderbolt/Mini Displayport and a USB port. Why would this work in Bootcamp with the same hardware, but not in OS X?
