basically works the adapter by pulling the DDC pins 6 + 7. For me, the projector is the main output device (is recognized by the computer) and the Monitor for monitoring purposes only (DDC Pins pulled, no recognition by the computer).
I had the problem that the projector had a higher resolution than the monitor and was displayed on the monitor therefore "Out of Range". I swapped the monitor against a model with higher resolution and then everything worked as it should.
However, there is a problem: If the monitor is off, it comes on the projector image disturbance. It seems that need this constellation of computer and projector a kind of "mass" or "resistance" at the second output. As for me, however, the monitor is running anyway, that's not a problem with me.
