I use the HDMI switcher to my PC and my PS3 to connect to my projector. The switch works as promised. Once I turn on my PS3, the image will change the switch automatically on my PS3. I turn the PS3 off again, the picture is switched back on my PC. The remote control only works if it is directed at the IR Recierver. Since the IR receiver attached to a long cable, it can be fixed so that this is not a problem. A manual switch is located on the switch possible. 3D movies are also transferred without restriction. Connecting a power supply is not necessary. To summarize: The switch does what it promises and at a fair price.
