        "content": "Here are several steps you can go through to try and restore casting / screen mirroring between your Windows 11 PC and your external display or monitor. Depending on your setup (wireless display, Miracast adapter, Chromecast, HDMI, etc.), you may only need a few of the steps. I\u2019ll also highlight things to check if something changed recently (updates, new hardware, etc.).\n\n---\n\n### \ud83d\udd0d Gather some basic information first\n\nBefore diving in, double-check these:\n\n- **How are you trying to connect?** Wireless (Miracast, Wireless Display Adapter, Chromecast, Fire TV, TV with \u201cMiracast-compatible\u201d built-in features) or wired (HDMI / DisplayPort / USB-C).\n- **Was this working recently and suddenly stopped, or is this a new setup?**\n- **Do you have administrator access** on the PC (for updating drivers, optional features)?\n- **What version of Windows 11** are you running (check in *Settings \u2192 System \u2192 About*)\u2014sometimes some features move around depending on version.  \n  ([support.microsoft.com](https://support.microsoft.com/en-us/windows/connect-your-windows-pc-to-an-external-display-that-supports-miracast-765f5cfc-6ef3-fba7-98da-c8267b001a5a?utm_source=openai))\n\n---\n\n### \ud83d\udee0 Basic troubleshooting\n\n1. **Check if your PC supports Miracast / Wireless Display**  \n   - Press **Win + K** \u2013 does the \u201cConnect to a wireless display\u201d panel appear? ([support.microsoft.com](https://support.microsoft.com/en-us/windows/fix-connections-to-wireless-displays-or-docks-in-windows-f6a7cd01-fdec-560c-4593-698a1b3098c4?utm_source=openai))  \n   - In *Settings \u2192 System \u2192 Projecting to this PC*, see if the \u201cWireless Display\u201d optional feature is installed. If not, you\u2019ll need to install it. ([support.microsoft.com](https://support.microsoft.com/en-us/windows/connect-your-windows-pc-to-an-external-display-that-supports-miracast-765f5cfc-6ef3-fba7-98da-c8267b001a5a?utm_source=openai))\n\n2. **Make sure the external display or adapter supports Miracast**  \n   - If using a dongle (wireless adapter) or smart TV, confirm it supports Miracast or is connected properly (e.g. correct HDMI input, dongle powered). ([microsoft.com](https://www.microsoft.com/en-us/windows/learning-center/how-to-set-up-a-wireless-display?msockid=2adb56da48a565a8326c401d49d164f9&utm_source=openai))\n\n3. **Ensure both devices are on the same network**  \n   - If using wireless display over Wi-Fi, your PC and the display need either to be on the same LAN or adhere to whatever connection protocol the casting system uses. Mismatched networks often cause visibility/connectivity issues. ([asavvyweb.com](https://www.asavvyweb.com/windows-11/cast-device-not-working-on-windows-11-laptop?utm_source=openai))\n\n4. **Turn Wi-Fi on** (and disable Airplane mode if accidental) on your PC. Wireless casting often depends on Wi-Fi or Wi-Fi Direct to handshake properly. ([support.microsoft.com](https://support.microsoft.com/en-us/windows/fix-connections-to-wireless-displays-or-docks-in-windows-f6a7cd01-fdec-560c-4593-698a1b3098c4?utm_source=openai))\n\n---\n\n### \ud83e\uddf0 Intermediate troubleshooting\n\nIf it still doesn\u2019t work, try these more detailed fixes:\n\n5. **Reinstall the Wireless Display optional feature**  \n   - Go to *Settings \u2192 Apps \u2192 Optional features*, remove \u201cWireless Display\u201d then reinstall it. ([guidingtech.com](https://www.guidingtech.com/fix-wireless-display-feature-not-working-on-windows-11/?utm_source=openai))\n\n6. **Update / reinstall device drivers**  \n   - **Graphics / Display driver** (Intel, NVIDIA, AMD)  \n   - **Network / WiFi adapter drivers**  \n   - Sometimes manufacturers release updates outside of Windows Update that fix Miracast bugs. ([allthings.how](https://allthings.how/how-to-fix-windows-11-not-detecting-second-monitor/?utm_source=openai))\n\n7. **Check settings like firewall, network discovery, and sharing**  \n   - Firewalls (especially on \u201cPublic\u201d network profile) can block device discovery.  \n   - Turn on relevant WLAN / Wi-Fi Direct virtual adapters in *Device Manager*. ([guidingtech.com](https://www.guidingtech.com/fix-wireless-display-feature-not-working-on-windows-11/?utm_source=openai))\n\n8. **Force Windows to detect an external monitor** (if wired)  \n   - In *Settings \u2192 System \u2192 Display*, there should be a \u201cDetect\u201d button to pick up connected monitors. Useful if it\u2019s a wired setup that\u2019s no longer showing. ([windowscentral.com](https://www.windowscentral.com/microsoft/windows-help/how-to-fix-second-monitor-not-detected-on-windows-10-and-11?utm_source=openai))\n\n---\n\n### \u26a0\ufe0f Things that might\u2019ve changed and could have broken things\n\n- A recent **Windows update** might have altered an optional feature or driver.  \n- You might have updated your graphics card driver or WiFi driver, and the new version has issues.  \n- If the monitor/TV or casting adapter had a firmware update (or reset), settings may have changed (e.g. HDMI mode, network settings).  \n- If your devices were added to a new domain, joined a corporate network, or had security/firewall policies enforced, that can block wireless discovery or Miracast usage.  \n\n---\n\nIf you want, I can walk you through a more personalized troubleshooting path based on your hardware (PC model, display/model, whether wireless or wired). Would you like me to help with that?"
