title: What are the requirements for a device to support screen cast over Chromecast dongle
body: <p>This <a href="https://support.google.com/nexus/answer/2865484" rel="nofollow">link</a> lists the supported Android devices that can cast their screen over a Chromecast dongle onto a bigger display. Why aren't other devices like Moto X or E present on the list (both on version 4.4.4 as per the requirement) ? I observed that the "Cast screen" option appears under Settings -> Display on these devices. But it doesnt work.</p>
  
  <p>Are there any hardware requirements for any device to support screen casting?</p>
  
  <p>Thanks in advance!</p>
