With its latest update, Amazon has brought a blast from the past to its modestly-priced Fire TV Stick 4K. The $50 streaming stick now supports Miracast, letting you mirror programs to supported smartphones, tablets and PCs as if they were attached displays, according to AFTVnews. Amazon had dropped Miracast support with Fire OS 6 on the Fire TV 3, but has now re-introduced it with the Fire TV Stick 4K.
