What is Miracast

Miracast is a standard technology for wireless connections. It enables you to mirror your devices (such as PCs, tablets, or mobile phones) to screens like TVs and projectors, wirelessly and seamlessly. To simply put, it’s regarded as HDMI over WiFi.

This is a widespread technology that has been adopted by many device manufacturers, and Microsoft has been one of them. As a result, for Windows 8.1 and Windows 10, Miracast is supported and you can use Miracast easily.

If your computer came with Windows 8.1 or Windows 10 OS, you can just add your TV or projector wireless.

If your computer has been upgraded to Windows 8.1 or Windows 10 from an older version, you can use a Microsoft Miracast adapter to connect.

Before setting up, you should check your computer and see if it supports Miracast technology. Follow the steps below:

  2. Type cmd and click OK.

  3. Copy and paste the follow command in your cmd, and press Enter.
    netsh wlan show drivers

  4. In the result, find Miracast and see if it’s supported.

If you see Wireless Display Support: No, your computer doesn’t support Miracast unfortunately. But you can still streaming your screen to your TVs via Google Chromecast, which is the alternative for Miracast.

If you see Wireless Display Supported: Yes, then your computer supports Miracast and you can use Miracast directly. Then continue to the next part: 2. Update avaialble drivers in your computer.

If Miracast is not supported, your computer doesn’t support Miracast unfortunately. But you can still streaming your screen to your TVs via Google Chromecast, which is the alternative for Miracast.

If Miracast is available, that’s great. And you’re good to go.

2. Is device drivers up to date in your computer?

Since Miracast is available in your Windows 7 computer or laptop, you can connect your computer screen to TVs or projectors wirelessly. Before setup, you should ensure that the drivers in your computer are up to date, especially your graphics card driver and network adapter driver.

There are two ways to update your drivers: manually and automatically.

Manually update drivers – You can manually update your drivers by downloading the latest version of your drivers from manufacturers, and installing it in your computer. This requires time and computer skills.

Automatically update drivers – If you don’t have time or patience, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

  1. Download and install Driver Easy.
  2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
  3. Click the Update button next to flagged devices to automatically download the latest drivers (you can do this with the FREE version). Then install the drivers in your computer.

    Or click Update All the automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).
  4. Restart your computer to take effect.

After updating device drivers in your computer, you can now start setting up Miracast for Windows 7.
