Hey, OP here. So you are correct, a computer needs to have WiDi support to be able to support Miracast. WiDi support, if I remember correctly, falls in with how old your processor is.
Miracast is not the same thing than Intel WiDi. All my laptops for instance support Miracast allowing me to cast to one of my two Microsoft Wireless Display Adapters on two different TVs, yet not a single one of my laptops supports WiDi.

Miracast has also nothing to do with CPU, it's a feature in modern wireless WiFi Direct network adapters (list of WLAN adapters supporting Miracast). Additionally the display adapter must support Windows Display Driver Model (WDDM) (almost all modern display drivers support it).

For laptop buyers there's a simple "rule of thumb": If the laptop came with Windows 8.1 pre-installed, its WiFi adapter supports Miracast. This is not a factual rule per se, it's just that those laptops manufactured mid 2013 and later usually have WiFi Direct wireless network adapter. Windows supports Miracast starting from version 8.1.

Desktop owners without built-in WiFi adapter need to check that adapter they get is a Wi-Fi Direct CERTIFIED Miracast device.

For laptop users like me Miracast is really practical, allowing use of more than one external display. In fact, Edge browser I am using to browse the forums and type this reply is at the moment on an external display connected with Miracast.
