Apparently, the people here are very divided as rum of distribution at all supposed to work. After I announced myself to the seller from which I have received it write this now as follows:
"Unfortunately, the adapter is only suitable to connect two devices to an LCD TV. Conversely, it does not work. The plug must be plugged in the LCD TV. Then, two playback devices (eg satellite receiver and X-Box to the two sockets ) are operated. Always the each running appliance is switched through to the TV. "
Another customer wrote the following, however:
"This Y-switch is working properly. However, only in one direction. For example, if a signal to two devices to be sent simultaneously.
However, Will you connect two devices to a screen does not work the Y-Soft. (Eg PS3 and Blue Ray Player) "
Certainly appears not to work well with many people. I had it as well:
From my AVR HDMI-out in the Y-junction and then insert the plug into the LED TV and one in the projector. That definitely works not really. Too bad. Have it returned.
Conclusion: do not buy!
Who really wants to operate multiple devices somehow should buy the following:
HDMI Splitter: to split a Eingansgerät on several terminals, eg AVR / X-box / satellite receiver to TV + projector (1 to 2; there are 1 to 3)
or
HDMI Splitter To connect multiple input devices in a terminal, such as Playstation + X-Box + satellite receiver to TV (2,3,4 1)
Hope I could help.
