Thank you for contacting the Intel Communities.
Here you can find some recommendations for this situation.
1. Look for the latest graphics driver for your laptop in the manufacturer website.
2. If the driver for the manufacturer is not supported in windows 10, uninstall the current driver, restart and let windows install the default driver.
3. Test different resolutions and check which are the supported resolutions in your TV.
4. Test the system with a different HDMI cable.
Another option would be to contact directly the OEM or manufacturer of your device, to advise you with any additional troubleshooting from their end.
