A driver is a program that controls a particular type of device that is connected to your computer. It is the software that an attached device uses to work with your PC. If your PC originally came with Windows 8.1 or Windows 10, then it most likely has Miracast support. Those who upgraded from Windows 7 to Windows 10 may not have this support.
If your computer does not have support for Miracast, there are other options you can explore. For instance, you can make use of Actiontec ScreenBeam USB Transmitter. This dongle and similar USB transmitters from other manufacturers enable wireless display on Windows 7 and Windows 8 laptops even though they don’t have support for Miracast.
Even if your PC supports Miracast, you will need to have updated Miracast drivers for it to work. Wireless (Miracast) displays can only be supported by Windows Display Driver Model (WDDM) 1.3 and later models. The easiest way to update your Intel WIDI Windows 10 is to download and install the Intel Driver Update Utility Tool.
This tool automatically checks and updates your drivers to the latest version. If your Miracast drivers are out of date, this tool will identify them and give you the option to have them updated. Follow the steps below to download this tool.

Step 5: Once the installation is complete, click on the ‘Launch‘ button.
Step 6: Click on the ‘Start scan’ button. The system will scan your system for available drivers. It will then list all the available drivers that need updating so you can update them.
Also, if the display you will project to does not support Miracast, you will need to complete the connection by buying a Miracast adapter for TV. This adapter plugs into one of the HDMI ports on your TV and makes it possible for your PC to communicate with the display wirelessly. Your best bet would be Microsoft Wireless Display Adapter because it comes from Microsoft but any other Miracast adapter would be fine.
