HP Dragonfly Pro Intel Core Ultra 7 155U Wireless Display Not Working Fix

The HP Dragonfly Pro is a premium business laptop built around collaborative work features. Wireless display (Miracast) allows you to project or extend to a compatible smart TV or display adapter wirelessly. When Miracast fails to connect — the display search finds nothing, or connections drop immediately — presentations and screen-sharing sessions become difficult.

This guide covers the most effective fixes for wireless display not working on the HP Dragonfly Pro with the Intel Core Ultra 7 155U processor.

Why Wireless Display Fails to Connect

• Wi-Fi driver not supporting Miracast or using an incompatible mode
• Target display or adapter does not support Miracast or is on a different network
• Windows Miracast service has a software conflict
• Outdated Intel Wi-Fi driver with Miracast bugs
• VPN or firewall blocking wireless display protocols

Step-by-Step Fixes

Fix 1: Verify Miracast Support on the Laptop

First confirm that the system supports Miracast:

1. Press Win + R, type dxdiag, and press Enter.
2. In DirectX Diagnostic Tool, check the System tab for Miracast: Available.
3. If it shows Not Available, update the Intel Wi-Fi driver — Miracast requires a driver that supports Wi-Fi Direct.

Fix 2: Update the Intel Wi-Fi Driver

An outdated Intel Wi-Fi 6E driver is a common cause of Miracast failures:

1. Open Device Manager and expand Network adapters.
2. Right-click the Intel Wi-Fi adapter and select Update driver.
3. For the best version, visit the HP Support page with your product number and download the Wi-Fi driver package.
4. Install and restart, then test Miracast again.

Fix 3: Disconnect VPN Before Using Wireless Display

VPN software routes network traffic through a tunnel that Miracast cannot use. Disconnect from VPN before attempting a wireless display connection. If a VPN must remain active, use a wired HDMI connection instead.

Fix 4: Use the Connect App

1. On the target TV or display, enable the Miracast or screen mirroring mode.
2. On the HP Dragonfly Pro, press Win + K to open the Cast panel.
3. Wait for the target display to appear and click it to connect.
4. If nothing appears after 30 seconds, ensure both devices are on the same Wi-Fi network or the TV is in direct Miracast mode (not network-dependent).

“Updating the Intel Wi-Fi driver made Miracast available where before it said not supported. The new driver version was available on the HP Support page even though Windows Update had not offered it.”

Fix 5: Reset Network Settings

Corrupted network adapter settings can prevent Wi-Fi Direct (which Miracast uses) from functioning:

1. Open Settings > Network & internet > Advanced network settings > Network reset.
2. Click Reset now and confirm.
3. After restart, reinstall the Intel Wi-Fi driver and test Miracast.
