Anyone know why only audio and not video plays when using miracast from my tablet to the projector? Bought the thing 3 days ago and setup went fine. I downloaded movie from my Amazon Prime account to tablet and everything was working great on test run. Suddenly there was no picture only sound when pressed play. Is this a technical issue with the device or connection issue. Downloads are legitimate from the Amazon app and same happens with Netflix. Why have a wireless device if it won't play content from your device? It's the only reason I opted for the more expensive wireless version of the player. Thanks.
