EZ Cast M2 Dongle. Miracast not working, options missing. I recently purchased a Chinese KitKat android Tablet PC and dongle and I want to be able to get Miracast working, but when I go into Settings > Display > Wireless display/cast screen to turn on this feature, these options are missing so I can't select anything. I have the latest KitKat Android software, which is up-to-date, so don't know what's going on. Any ideas anybody? Your help will be most appreciated.
