Hi Mikey57,
If Windows reports that Miracast is not supported by the graphics card, the most common cause is that one of the required hardware components or drivers does not currently meet Miracast requirements. Miracast relies on support from both the graphics adapter and the wireless adapter.
To help identify the limitation, please check the following:
1, Press Win + R, type dxdiag > Enter and save the report. Review the Miracast entry in the generated file.
2, Open Command Prompt and run: netsh wlan show drivers
- Check whether Wireless Display Supported is listed.
If your device hardware does not support Miracast, Windows is unable to enable the feature through software changes alone. In that situation, a practical workaround is to use a wired display connection such as HDMI or consider hardware that supports wireless projection.
I hope this helps clarify the situation. Let me know if you need further assistance, feel free to ask me by clicking "Add Comment" or "Add Answer" if you cannot add comment so your response will be visible. Thanks for your effort.
