How to get PC to support Miracast?

His dxdiag.txt file attached to the OP states his display adapter does not support Miracast.

Didn't notice that, I just checked OP's system specs which only told about a desktop PC.

What those specs mean is it's time to get both, new display adapter and WiFi adapter.

But are we sure the WiFi adapter does not already support Miracast without replacing the display adapter first?

Kari said:

Exactly!




This is quite simple: To cast from PC to a Miracast display, both your PC's video adapter and wireless network adapter need to support Miracast / WiDi (wireless display). Miracast Wireless Standard was announced in September 2012, and almost immediately both display adapter and WiFi adapter manufactures started to support it. A rule of thumb is, if your PC came with pre-installed Windows 8.1 or later operating system, and it has integrated WiFi, it and its devices are new enough to support Miracast.

As mentioned earlier, it's not enough that your display adapter supports Miracast. WiFi is also required as can be easily seen in following two screenshots. As long as I have my laptop's WiFi adapter enabled (it does not have to be connected to wireless network, just enabled), I have the option to connect to wireless display:

If I disable my WiFi adapter, Miracast is no longer supported and Connect to a wireless display link will not be shown. My display adapter still supports Miracast but as it needs WiFi, too, I can't cast to wireless display:

I understand what OP wants, Miracast is practical. For instance in my case it's the only way I can use three displays on my laptop. In screenshot I am typing this reply on laptop's own display in the middle, streaming today's breakfast TV from my greatly missed native Finland on Miracast display (Smart-TV with a Microsoft Wireless Display adapter) on left, leaving the HDMI connected external monitor on right for running Hyper-V virtual machines, computer maintenance and so on:
