This objective satisfies the switch without any major problems.
I can direct the receiver to the TV and Blue Ray player to the projector even simultaneously. However, then the lowest common denominator for the HDMI options is taken.
Therefore, the TV (full HD 3D no but) must be switched off, if I on the projector (also full HD but with 3D) one wants to see 3D movie, otherwise the projector shows no 3D.
Occasionally turn the switch the signal is not automatically to the connected device. But that can then switch on the remote control.
The audio output I have not tried because I run the sound separately via an AV receiver, or pass on to the TV via HDMI.
