I currently use a BMD DVI to SDI converter (via a DP to DVI cable) on the output of my mid-2012 15" MBP but, when I introduce an IoXT into the chain, the converter is recognised by the MBP in the Display Settings but will not output a picture.
I remember that this didn't work on the early IoXT firmware versions but there was the promise of an update to fix the issue. Did this ever happen? Anyone running this successfully? I know the BMD device can be flaky at the best of times so, maybe, there's the problem(?)
I'm running IoXT Firmware version 10.4.7 and Mac OS 10.8.5
