I recently needed to do a reformat & reinstall of OSX on my MacPro 12 core and in doing so downloaded OSX 10.8.5 since that's what you get in the process. Now my Decklink mini monitor, is not giving me any vido on my monitor. The signal is there since the monitor recognizes it's getting a 1080i/59.94 signal, but no video nor audio.
Any suggestions how to remedy this problem. Apple had the machine for 4 days & ran all their diagnostics, plus replaced the back plane board and the machine checks out just fine, just no video.
