What is Projecting to this PC and How To Use it on Windows 10

0

In a nutshell, Projecting to this PC is a feature that lets you wirelessly connect to another computer’s monitor and use it as your second monitor. For example, if you have two Miracast supported computers, you can use Computer A as your main computer and link Computer B’s screen via Wireless Display technology as your second monitor. That being said, in order to make Projecting to this PC to work, you will need both computers’ hardware that supports Miracast.

How to check if my PC supports Miracast

To get Miracast to work, you basically need two things, a display adapter that supports Windows Display Driver Model (WDDM) 1.3 and above and a Wi-Fi adapter that supports Wi-Fi Direct.

To check if your display adapter supports WDDM 1.3 and above, click Start menu, type dxdiag into the search box and select dxdiag from the search result. When the tool opens, go to the Display tab and check the Driver Model. If it says WDDM 1.3 or above like below, the display adapter is Miracast-ready.

Now, run this old-school command line in a Command Prompt window. If you see a wireless adapter with the description of “Microsoft Wi-Fi Direct Virtual Adapter“, your Wi-Fi adapter is also Miracast-ready.
