Want to cast your PC screen wirelessly to a TV or projector? Well, you can easily do so using  Miracast technology. Gone are the days when cables were the only means for transmitting media content from a PC or any other compatible device to an HDTV: Miracast is quick, easy and secure. In this guide, we will teach you how to easily setup and use Miracast on your Windows 10 PC.

What is Miracast

Miracast is a certification standard run by the Wi-Fi Alliance that allows mirroring of content wirelessly from a compatible PC, smartphone, or a tablets screen to a television or monitor. It can simply be described as “HDMI over Wi-Fi” since it allows content to be cast from one device to another display without the use of cables. Wireless streaming has achieved popularity and nowadays most streaming devices come with support for Miracast.

First offered in Windows 8.1, Miracast allows sharing of 1080P HD videos (H.264 Codec) and 5.1 surround sound, which means it can also give you a theater-like experience. Most new computers being shipped with Windows 8.1 and Windows 10 are Miracast enabled. At times, Miracast may not work for two reasons: either it’s not supported on your wireless display, or your PC has outdated drivers. To check whether Miracast is supported on your device, follow the procedure below.

How to check if your Windows PC supports Miracast

Here’s how to quickly check whether your Windows computer has support for Miracast.

Step 1:  Press ‘Win + R’ keys on your keyboard to open the Run dialog, then type ‘dxdiag’ and hit enter.


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

Step 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.


Step 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)

In my case , it showed Miracast not supported since I tested with Windows 7 which has no support for Miracast.

Get current Miracast drivers for your PC

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 wireless driver and software 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 1: Download Intel Driver Update Utility Tool from this link

Step 2: Locate the download folder and click on the .exe file to run it.

Step 3: Accept the license terms and conditions in the page that will open and click on the ‘Install‘ button.


Step 4: The system will display the progress bar. Wait for the installation process to complete.


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.

Miracast has become a very popular way of projecting content from PC to HDTVs and other large displays. Many manufacturers have embraced the new display standard and the market has seen a plethora of Miracast enabled devices since 2013 when the Wi-Fi Alliance first announced it at CES. Users can now seamlessly mirror the displays of their Miracast-certified tablet, phone, or laptop to any Miracast supported receiver such as an HDTV, monitor, or projector. Apart from mirroring your content to the large screen, Miracast secures your connection with WPA2 encryption so protected content can freely flow through it.
