NOTE: Before I get into the how-to, I have to say that this technology is incredibly hit or miss. What do you need to wirelessly mirror your device screen to your TV? Likewise, if you’re watching a video and you suddenly decide you want to check your email, that’s what will show up on your TV screen.
