Chromecast has locked my TV on to a screensaver. Can't play anything from my laptop (MacBook Air) to the TV. I have the button in the top Chrome menu bar but if I say select Netflix and play something it doesn't appear on the TV.
Any ideas?
PS. I have no idea whether it's a Gen 1 or Gen3 Chromecast as it doesn't say on the box but I just bought it today.
