Connection dropouts.

Have connected to a media player to the projector (BenQ W770ST) cable. Basically the connection works, unfortunately, it is not reliable. The projector loses off and for a short time the connection. At best, this is indicated by a short text message "source identified" without Bildausetzer. Unfortunately, it also happens that the connection is too long unstable. Then the projector from the 3D mode drops out and does the movie experience clouding readjust the 3D mode. Although the cable is very cheap, but worth it here probably spend a few euros more. I would not buy it again.
