Miracast is a WiFi Standard

A simple way to understand Miracast is "HDMI over WiFi". What that means is, rather than connecting a physical HDMI cable from your computer to another device, you use WiFi to do so.

Also, rather than going through your router or home network, the signal travels directly. For example, if you use Miracast to show your Windows 10 laptop on your television, your laptop connects directly to your television, with no network, or other devices, between.

Windows 10 Miracast Options

Windows 10 supports Miracast from a software perspective. Meaning, it has all the abilities for Miracast built-in, and it does not require further software.

However, the specific hardware inside your computer must also support the Miracast standard. This includes a WiFi adapter and driver that offers the ability, and a video card and driver that also supports using Miracast.

2. Check Miracast Support

There are three ways to check if your computer supports Miracast:

• Try To Cast
• While not 100% accurate, it can be a quick, easy way to see if there's any casting support on your system.
• Checking Display Settings
• Again, not perfectly accurate, but if key combinations are difficult, some may find this method easier.
• Check Using DxDiag
• DxDiag is a utility to get very precise information about your system and it's capabilities. This gives a definitive answer when it comes to Miracast support on your system. Though a little more difficult to access, this guide will take you through it step-by-step.

Check Quickly by Attempting to Cast

1. Press the Windows key and P key on your keyboard at the same time.
   

1. You will be presented options on the right to cast your screen if Miracast is supported.
2. Miracast Available
3. If Miracast or another screen share option is available, a couple choices to project to will be displayed.

1. Miracast Not Available
2. If Miracast is not available, a message recommending reinstalling drivers or using a different video card is shown.

Check Display Settings

1. Select the Start Menu, then select Settings.
   

1. Select System.
   

1. Select Display on the left.
   

1. Look under the Multiple Displays section for "Connect to a wireless display".
2. Miracast Available
3. Under Multiple displays, you will see "Connect to a wireless display".

1. Miracast Not Available
2. Under Multiple displays, the text won't appear.

Check Using DxDiag

1. Using your right mouse button, right click on the Start Menu.
   

1. Select Run.
   

1. In the Run window, type in 'dxdiag', then select OK.
   

1. In the DirectX Diagnostic Tool, select Save All Information... at the bottom.
   

1. Select Desktop on the left (so the file is easy to find in a moment). The file name will already be filled in as DxDiag. Select Save.
   

1. Open the DxDiag text file on your Desktop.
   

1. Under System Information, Look for Miracast.
2. Miracast Available
3. Miracast will say that it is available, usually with the HDCP feature.

1. Miracast Not Available
2. Miracast will state that it is not available.

1. You can safely delete the DxDiag text file from your desktop. It's just a report, and does not control anything.
