We have a Xyboard 10.1 running Android 3.22. We have the tablet connected to our TV via the HDMI output on the tablet dock. We're trying to watch a streaming Netflix movie. The Netflix user interface is visible on the TV. When we select a movie to watch we see the red Netflix screen on the TV while it buffers, but as soon as the video starts playing we only get audio on the TV, and the TV screen goes blank other than the playback controls across the bottom of the screen (which disappear when they time out). The movie video is visible on the tablet. Any ideas?
