What is Wireless Display?
As some Android users know that Miracast is officially supported since Jelly Bean 4.2. Most Android phone manufactures usually name this feature as wireless display. Of Course, some vendor give it a different name for marketing purpose, for example, Samsung uses the name of “screen mirroring” for Galaxy S4 and Galaxy Note 3.
Moto G wireless display simply does not work
Moto G come with Jelly Bean 4.3. In last December, Motorola updated the phone to Android KitKat 4.4.2. But you may find out that there is no option to enable Moto G wireless display no matter it is in Jelly Bean 4.3 or KitKat 4.4. There is no way to get wireless display in Moto G.
Of course, if we check the brother of Moto G, you can find out that Moto X fully supports wireless display.
So, missing Moto G wireless display is not an inadvertent mistake; it is done deliberately.

- WiFi connection and Miracast cannot be used simultaneously in Moto G. If the wireless display is enabled (it uses WiFi direct per Miracast standard), the WiFi connection to your router will be shutdown and therefore you have to use mobile data for internet connections. Some Sony devices (2013) suffer from this issue either. To avoid negative feedback, and inadvertent usage of mobile date (remember that Moto G is targeted at users with moderate mobile data usage), Motorola has to disable this feature.
- Even you manage to enable Moto G wireless display (root is needed, and it is not a simple task. Do NOT ask me how to do this. I do not show things that I do not recommend), the performance is not so good. There is noticeable delay and sound sync seems not good as well. Probably due to hardware issue, or Motorola did not do any optimization, or both (because it will
