Quick Note: Prerequisites and Basic Checks

• Ensure your Windows 10 PC is updated: Updates often include bug fixes that improve device compatibility.
• Check the adapter’s power source: The adapter needs to be plugged into a power outlet or USB port to function properly.
• Verify TV or monitor input: Make sure your display is set to the correct HDMI input where the adapter is connected.
• Keep the adapter close: For the best connection, keep the adapter within 15 feet (about 5 meters) of your PC.
• Restart all devices: Sometimes, simply rebooting your PC and the display device can resolve connectivity issues.

Step 1: Restart Your Devices

Restarting both your Windows 10 PC and the display device (TV or monitor) is the easiest and quickest way to fix temporary glitches. This refreshes the system and clears minor errors that may be causing connection problems.

1. Turn off your PC.
2. Unplug the Microsoft Wireless Display Adapter from the TV and power source.
3. Wait for about 30 seconds.
4. Plug the adapter back in and turn on your TV or monitor.
5. Turn your PC back on and try connecting to the adapter again.

Step 2: Check Wireless Display Settings on Windows 10

Windows 10 has built-in features to connect to wireless displays. Ensuring these settings are correctly configured is important for your adapter to work.

1. Click the Start menu and select Settings (gear icon).
2. Go to Devices > Bluetooth & other devices.
3. Click on Add Bluetooth or other device.
4. Select Wireless display or dock.
5. Find your Microsoft Wireless Display Adapter in the list and select it.
6. Follow the on-screen instructions to connect.

If your adapter does not appear in the list, make sure it is powered on and connected to the TV correctly.

Step 3: Update Wireless Display Adapter Firmware

Firmware controls how your adapter works. Outdated firmware can cause compatibility problems with Windows 10. Updating it can fix bugs and improve performance.

1. Download the Microsoft Wireless Display Adapter app from the Microsoft Store.
2. Open the app and connect to your adapter.
3. If a firmware update is available, the app will prompt you to install it.
4. Follow the instructions carefully and do not disconnect the adapter during the update.

Step 4: Run the Network and Hardware Troubleshooters

Windows 10 includes troubleshooters that can automatically detect and fix common hardware or network issues that might affect the adapter.

1. Open Settings > Update & Security > Troubleshoot.
2. Click on Additional troubleshooters.
3. Select Network Adapter and click Run the troubleshooter.
4. Follow the instructions to complete the process.
5. Next, select Hardware and Devices and run that troubleshooter as well.

These tools will attempt to fix issues like driver conflicts or network problems that can interfere with the adapter.

Step 5: Check Display Driver and Update if Needed

The display driver is software that helps your PC communicate with the screen and connected devices. If it is outdated or corrupted, the adapter might not work properly.

1. Right-click the Start button and select Device Manager.
2. Expand the Display adapters section.
3. Right-click your display adapter and select Update driver.
4. Choose Search automatically for updated driver software.
5. Follow any prompts to install updates.
6. Restart your PC after updating.

If Windows doesn’t find any updates, you can visit your PC manufacturer’s website to download the latest drivers manually.

Step 6: Reset the Microsoft Wireless Display Adapter

If the adapter still isn’t working, resetting it to factory settings can resolve deeper configuration problems.

1. Press and hold the button on the side of the adapter for about 15 seconds until the LED indicator blinks rapidly.
2. Release the button and wait for the adapter to restart.
3. Reconnect your Windows 10 PC to the adapter following the standard connection process.

This resets all settings on the adapter and can fix persistent connection issues.

Advanced Option: Use the Connect App on Windows 10

Windows 10 includes a built-in Connect app that helps with Miracast connections like the Microsoft Wireless Display Adapter.

1. Press Windows + S and type Connect.
2. Open the Connect app.
3. Make sure your adapter is powered on and ready.
4. Your PC should automatically search for available wireless displays.
5. Select your adapter from the list to connect.

This method is useful if the standard device list does not show the adapter properly.
