The device works and recognize my Oppo 93 Bluray player only properly when it is connected directly. With my Denon Amplifiers This did not work, and the Darbee tablet can not be "interposed". Due to this, I have even a new AV Receiver with 2 HDMI outputs gained (Sony STR 1040). Here the same games, the 2.Output can not be used. On request of the incompatibility I got the following from BenQ answer: "It is unfortunately to the compatibility that is MH680 a business model for small Open to thought and not for home theater, why some receivers and home theater systems are not supported". The instrument itself is great and raises even in daylight a super sharp image on the screen! Go when you buy it from, to connect a Bluray player directly and an optical cable to the receiver. Disadvantage: I can not gamble or use other video sources, for which I have actually bought the Sony AV receiver str1040 now. Great device - Schei ... compatibility!
