How to check if your Windows PC supports Miracast

1.Press Win + R keys on your keyboard to open the Run dialog, then type dxdiag and hit Enter.

2.DirectX Diagnostic Tool window will open. After the tool finishes collecting all the information about your computer, click on the Save all Information button.

3.Now you have to choose where you want to save the DxDiag.txt file on your computer. You can save it on a quick to access location such as your desktop.

4.Open the DxDiag.txt file which is usually in notepad format. Scroll towards the bottom of the report where you will find the status of the Miracast on your PC. It will either read Miracast is available, in which case your TV will be ready to cast its display to a compatible device or read Miracast not supported in which case you might want to explore other options (described below).
