My current configuration: (And everything works "Nickel"):
5 input devices (decoder in 1, 2 PS3, Lacie-Cinema 3, Apple TV 4 MacMini 2nd screen Thunderbold Port HDMI converter + 5). A TV output and Overhead BinQ 3D output B.
REM: I have 5 meter HDMI cable between the PC and the Spliter and 12 meters between Spliter and projector, no amp and 3D works great from the Mac, the decoder and the PS3.
Only a small flat (not serious at all), the sound output (3.5mm) that goes to my amp is apparently considered as output A, I did not find how to select the output B except by putting the same inputs in A and B, eg, A3-B3, A5-B5, etc ...
Does not matter if is that the TV and the projector are the source in this case. anyway you look down 3 different things at the same time and in general like all my entries also come directly into the amp, I still do what I want.
But if it is possible, and that qqu knows how to do, thank you to know.
Maybe it would have been nice that the 5V DC power supply is integrated into the case, but in case of failure of the latter, it is perhaps no worse.
In any case this product is great and I am more than happy.
