**Many Windows 11 and 10 users are experiencing issues with their USB-C monitors suddenly becoming undetectable, often after recent Windows updates.** This can be frustrating, but there are several troubleshooting steps you can take to get your monitor working again.

**Common Causes:**

* **Outdated or incompatible drivers:** Windows updates can sometimes cause driver conflicts.
* **Hardware issues:** A damaged USB-C cable, port, or adapter can also disrupt the connection.
* **Power management settings:** Windows 11 might be turning off USB ports to save energy, affecting connectivity.
* **Incorrect BIOS/UEFI settings:** These settings might disable USB-C functionality or video output.

**Troubleshooting Steps:**

1. **Check Connections:** Ensure the USB-C cable is securely connected to both your monitor and PC. Try using a different USB-C cable or a different USB-C port on your device. Make sure the cable and port support video output.
2. **Update Drivers:** Check for updates for both your graphics drivers and USB-C drivers. Look for error symbols in Device Manager and update or uninstall any problematic drivers.
3. **Disable USB Power Management:** In Device Manager, go to the “Universal Serial Bus controllers” section, right-click on each USB Root Hub/Generic USB Hub, and disable the “Allow the computer to turn off this device to save power” option.
4. **Disable USB Selective Suspend:** In Power Options, go to “USB settings” > “USB selective suspend” and set it to “Disabled” for both battery and plugged-in modes.
5. **Roll Back Windows Updates:** If the issue started after a recent update, try rolling back the update to see if it fixes the problem.
6. **Check BIOS/UEFI Settings:** Make sure USB-C ports and related features are enabled in your BIOS or UEFI settings.
7. **Contact Manufacturer Support:** If none of these steps work, reach out to your device manufacturer for further assistance.

**Important Note:** Your device and monitor must be compatible with DisplayPort Alternate Mode (DP Alt Mode) or Thunderbolt 3/4 standards to ensure video output through USB-C in Windows 11.

By following these steps, you should be able to resolve your USB-C monitor detection issues in Windows 11/10.
