Wireless Display Not Working in Windows 11? Fix It

If your wireless display or Miracast connection fails on Windows 11, the fix usually involves updating your Wi-Fi and graphics drivers, restarting the Wireless Display service, or checking that your PC and TV both support Miracast. Below are the exact steps to diagnose and resolve the most common causes, from driver conflicts to disabled features.

What Is Wireless Display and How Does It Work?

Wireless display on Windows 11 uses Miracast, a standard that streams audio and video over a direct Wi-Fi connection. Your PC acts as the source, and a TV, projector, or another PC acts as the receiver. Unlike casting over your home network, Miracast creates a peer-to-peer link, so both devices must support the protocol and be within range (usually about 30 feet). Windows 11 includes the “Wireless Display” optional feature, which lets your PC act as a receiver too.

First: Check Hardware and System Requirements

Before troubleshooting software, confirm your devices can actually connect. Your PC needs:

Windows 11 with the latest updates installed
A Wi-Fi adapter that supports Miracast (most laptops and many desktops do)
A graphics driver that supports Miracast (Intel, AMD, or NVIDIA)
A receiver that supports Miracast – most smart TVs and streaming sticks do, but check the manual

To verify Miracast support on your PC, press Win + R, type dxdiag, and press Enter. In the DirectX Diagnostic Tool, click Save All Information, open the saved file, and look for the line “Miracast: Available” or “Miracast: Not Available.” If it says not available, your hardware or driver doesn’t support wireless display.

Common Causes and Quick Fixes

If Miracast is available but connections fail, try these in order:

Restart both devices – turn off your PC and the display, wait 30 seconds, then turn them back on.
Update your Wi-Fi and graphics drivers – open Device Manager, expand “Network adapters” and “Display adapters,” right-click each, and select “Update driver.” Choose “Search automatically.”
Restart the Wireless Display service – press Win + R, type services.msc, find “Wireless Display,” right-click it, and select “Restart.”
Run the hardware troubleshooter – go to Settings > System > Troubleshoot > Other troubleshooters, then run “Hardware and Devices.”
Check Windows features – go to Settings > Apps > Optional features > More Windows features, ensure “Wireless Display” is checked (if you want to receive, not just send).

When the Display Isn’t Detected

If your TV or projector doesn’t show up in the list when you press Win + K, the receiver may be off, not in pairing mode, or on a different Wi-Fi channel. Make sure the display is set to its “Screen Mirroring” or “Wireless Display” input. Also, temporarily disable your VPN or firewall – they can block the discovery packets Miracast uses.

Connection Drops or Freezes After Connecting

If the connection works but then stutters or drops, the usual culprits are Wi-Fi interference and power management. Try:

Move closer to the display and remove obstacles like walls or metal objects.
Disable Wi-Fi power saving – go to Device Manager, expand “Network adapters,” right-click your Wi-Fi adapter, select Properties > Power Management, and uncheck “Allow the computer to turn off this device to save power.”
Change the wireless band – if your router has both 2.4 GHz and 5 GHz, switch your PC to the 5 GHz band for less interference.
Update your display’s firmware if it’s a smart TV – check the manufacturer’s support site.

When Your PC Should Act as the Receiver

Windows 11 can receive a wireless display from another device, but you must enable the “Wireless Display” optional feature first. Go to Settings > Apps > Optional features > Add an optional feature, search for “Wireless Display,” install it, then open the “Wireless Display” app from Start. Your PC will then appear as a device on other screens. If it doesn’t appear, make sure your PC is on the same Wi-Fi network as the source device and that Bluetooth is on (some pairing methods use it).

Frequently Asked Questions

Why does my Windows 11 PC say “This device doesn’t support Miracast”?

This message appears when your Wi-Fi adapter or graphics driver lacks Miracast support. Update both drivers from the manufacturer’s website, not just via Windows Update. If your hardware is older than about 2015, it may genuinely not support Miracast – in that case, you’ll need a separate wireless display adapter that plugs into an HDMI port.

Can I connect to a TV that doesn’t support Miracast?

Yes, if you plug a Miracast receiver (often called a “wireless display adapter”) into the TV’s HDMI port. These adapters are inexpensive and turn any HDMI display into a Miracast receiver. Once plugged in, switch the TV to that HDMI input and it should appear in the Win + K list.

Why does the connection work but there’s no sound?

Miracast carries audio, but your PC might be sending it to a different output. Click the speaker icon in the taskbar, then click the current output name and select the wireless display. If it’s not listed, open Settings > System > Sound and choose the display as the output device. Also, make sure the TV’s volume isn’t muted.

Does using wireless display drain the battery faster?

Yes, streaming video over Wi-Fi uses more power than normal browsing. Expect noticeably shorter battery life on a laptop. To reduce drain, lower the screen brightness and close unnecessary apps. Plugging in the laptop is the only reliable way to avoid the battery dying mid-presentation.

Is wireless display the same as casting to a Chromecast?

No. Miracast mirrors your entire screen and doesn’t require a router – it’s a direct connection. Chromecast uses a different protocol (Google Cast) that streams specific apps over your home network, and it requires the app to support casting. Windows 11 can cast to Chromecast devices using the “Cast” feature in some apps, but it’s not the same as the native wireless display feature.
