Unfortunately, the first device was broken, but was exchanged quickly and easily. Now everything works. He supports HDMI 1.4, I can now also watch BluRay's in full 3D. The projector automatically switches to 3D. When you switch between input sources, it takes about 3-5 seconds to come back an image. But this is apparently all so (Previously had a Digitus). Does not matter, because you normally do not so often switches. The workmanship is very high (metal housing) and the remote control is working properly. Very good is also that the LED's are not too bright as when Digitus.
I can recommend the Matrix Switch all those who want to connect up to three devices on two TV's or projectors.
