Want to mirror your Windows 10 PC screen to a TV, a monitor or a projector? You could adopt the Miracast technology to easily achieve it. This article will introduce what is Miracast and how to setup and use Miracast on a Windows 10 PC.
According to Wikipedia, Miracast is a standard for wireless connections from devices like laptops, tablets, or smartphones, to external displays such as TVs, monitors or projectors, rolled out by the Wi-Fi Alliance. It can roughly be described as "HDMI over Wi-Fi", replacing the cable from the device to the display.
With Miracast, you could easily create a wireless connection between your Windows 10 computer and any external display devices.
Outdated device drivers or not Miracast-certified external display device will cause Miracast not working on your Windows 10 PC. Therefore, you need to check whether your Windows 10 PC supports Miracast. Here’s what you need to do.
Step 1. Press Windows + R at the same time to bring up the Run dialog
Step 2. Type dxdiag and hit Enter
Step 3. The DirectX Diagnostic Tool window will appear. Click the Save all Information button at the bottom once the tool finishes collecting all the information about your computer
Step 4. Save the DxDiag.txt file at your desired location on your computer
Step 5. Open the DxDiag.txt file and look for Miracast. The availability status of Miracast can be viewed.
Note: The status of Miracast will be either Miracast is available or Miracast not supported. If it is the former case, your Windows 10 PC screen could be cast to an external display device. And if it is the latter one, you can’t make a wireless connection via Miracast.
