Having to repeatedly deactivate and reactivate your graphic driver to get your TV to detect an HDMI connection from your laptop is certainly inconvenient. Here are some potential solutions to resolve this issue:
1. **Update or Reinstall Graphics Drivers**: Outdated or corrupted graphics drivers are a common cause of HDMI connection issues. Ensure that your graphics driver is up to date. If it is, try uninstalling and then reinstalling the driver. This can often resolve strange behavior like what you're experiencing.
2. **Check HDMI Cable and Ports**: Sometimes, the issue can be as simple as a faulty HDMI cable or port. Try using a different HDMI cable or another HDMI port on your TV to rule out a hardware issue.
3. **TV Settings**: Check your TV settings. Some TVs require you to select the correct input manually or adjust settings to recognize new connections properly.
4. **Display Settings on Laptop**: Go to your display settings (right-click on the desktop and select "Display settings") and ensure that the TV is recognized and set up correctly when connected. Sometimes, setting the TV as the primary display or extending displays can help.
5. **Windows Update**: Make sure your operating system is fully updated. Some HDMI connection issues can be related to system bugs that are fixed in newer updates.
6. **Different HDMI Modes**: Some laptops have different modes (like mirror, extend, etc.) that can be toggled with function keys. Ensure you're using the correct mode for your needs.
7. **Power Management Settings**: In some cases, power management settings can interfere with the way hardware, like graphics cards, operate. Adjust these settings in the Control Panel to prevent the graphics card from being turned off or put in a low-power state.
8. **BIOS/UEFI Update**: Rarely, the issue could be at the BIOS/UEFI level, especially if it's a hardware compatibility issue. Check for any available updates from your laptop manufacturer. However, proceed with caution as updating BIOS/UEFI can be risky.
9. **Use a Different Device**: Test the HDMI connection with a different laptop or device. This can help determine if the issue is with your laptop or the TV.
10. **Professional Support**: If none of these steps work, consider reaching out to the laptop's manufacturer for support, especially if it might still be under warranty.
By systematically going through these steps, you should be able to identify and resolve the issue with your HDMI connection.
