First post here, thanks for all the info so far.
So, my problem is this. I can access the Cromecast dongle fine, but as soon as I activate it to watch a film (I'm UK based, its FILM not MOVIE!), the screen on the tablet breaks up into what appears to be too high a resolution. The TV shows a perfect picture, but it means I cant get to any on-tablet buttons to start the film. Any ideas?
Cheers
