A:Answer I can unfortunately confirm this user's experience. A 2013 MacBook air has a mini display port (v1.2 out) but this monitor refuses to show the Mac. The Mac "knows" there is an external monitor connected, but the monitor remains black. I tired changing the display port version down to 1.0 in the monitor settings, running monitor diagnostics did not help either. I've tried this with two different mini DP to DP cables, one of which is new, so it seems this monitor will not work with older Macs. Only the mini DP to HDMI seems to work, so you've got to downgrade your resolution.
