How to check if a Win10 computer supports Miracast screen mirroring?｜BJCast

Windows 10 continues to support Miracast on the basis of Win8.1. You can wirelessly transmit audio and video, and wirelessly mirror the display to the large screen. However, not all laptops or tablets with Windows 10 installed support Miracast functionality. Can we also test and verify whether it is supported by running the Dxdiag.exe command?

Does the Dxdiag.exe command support miracast on the computer

1. The WIN+R combination key starts “running” the program [the grid+R between Ctrl and Alt];

2. Enter “dxdiag. exe” in the input box of the “Run” program, and confirm that it will not pop up immediately. It usually takes 5-10 seconds for the DrectX diagnostic tool page to pop up;

3. Pop up the DrectX diagnostic tool, select “Yes” to start testing;

4. When the detection progress bar disappears, it indicates that the detection is complete and “save all information” to the desktop;

5. Open the saved TXT document, press Ctrl+F to search for “Miracast”. If the following words are found, it indicates that the Miracast function is not supported;

Miracast: NotAvailable means not supported, Miracast:: Available, with HDCP means supported.

PS：Computer Miracast screen casting requires our system, graphics card, and network card to support the Miracast protocol, which is indispensable. Computer hardware does not support Miracast:, so users can only replace hardware devices or use wireless screen mirroring devices as a “bridge” for screen mirroring. Wireless screen mirroring devices are currently the mainstream cross platform display devices.
