I bought a Pioneer VSX924 - this AVR is having trouble with the HDMI handshake to the projector. A Benq TH681 I could not be persuaded to a picture show. The Optoma HD141x worked only after repeated switching on and off of the AVR.
Then interposed the speck here and behold the works connect hitherto always 100%!
Delivery was as always top. Product does what it says.
