How to Connect Windows 10 to TV Wirelessly Miracast

Authored by: Support.com Tech Pro Team

1. Introduction

There's multiple ways to mirror your Windows 10 desktop to your Smart TV. This guide will walk you through checking for Miracast support, and if any other methods are open to you.

2. Check Computer for 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.

HDMI Connection
If your computer does not support Miracast, you can still use an HDMI cable and connect your computer using a wired connection.

3. Check TV for Miracast Support

If you know the exact make and model of your television, you can check online if it supports Miracast.

Otherwise, you can check in the menus of the television itself to see if Miracast or casting is listed as an option.

Check Online

The WiFi Alliance, the group that controls and sets the standard for Miracast support, maintains a list of Smart Televisions and other devices that support Miracast.

If you know the make and model of your Smart TV, you can search for it on their site to verify your Smart TV supports Miracast.

Check on your Television

Every Smart TV is slightly different, and each menu is slightly different. This guide will provide the best places to look for Miracast support.

If you'd prefer, there's a few places you can check on your Smart TV directly, to see if Miracast is supported.

Apps

Check if your Smart TV considers Miracast an app you can run.

1. Press the Menu button on your remote and select Apps for your Smart TV.
   

1. Look for "Miracast", "Screen Casting", or "Wi-Fi Casting" apps.

Input

Sometimes, Miracast is considered another input, rather than an App in and of itself.

1. Select Input or Source.
   

1. Look for "Miracast", "Wi-Fi Casting", or "Screen Casting".

HDMI Connection
If your television does not support Miracast, you can still use an HDMI cable and connect your computer using a wired connection.
