Thank you for contacting the Intel community.
Could you please provide us with your system model, processor model and system maker?
Also, I will appreciate if you can provide us with the TV model and the operating system you have installed.
Olá, seguem as informações solicitadas.

In this case, your best contact support is with your computer manufacturer as they are more familiar with your PC and how the components interact with each other. Contact your computer manufacturer, and have them verify the proper working functionality of your system.
However, you can try the following:
- Check all connections to make sure there are no loose cables.
- Unplug the HDMI cable and plug it in again. Do not use any adapters; make sure you use straight HDMI connection.
- Check that the port is not disabled in the BIOS.
- Try troubleshooting using a different HDMI port or cable if one is available for you.
If the above does not work try this:
Update the System BIOS via the instructions and BIOS software provided by your computer manufacturer.
Note: If you are attempting to connect to a TV that supports 1080p, 4K, 3D or Deep Color, you will need to use a High Speed HDMI Cable. To verify you have one of these, look along the cabling itself for the printed text which says “High Speed HDMI Cable.” If it is not there, you may not be using a cable that is required to work with your display device
If nothing works, try uninstalling the graphics driver and reinstall the Intel® generic driver manually, you can download it here:
Please see Uninstalling the Intel® Graphics Driver and Intel® Display HDMI/Audio Driver and check How to Manually Install a Graphics Driver in Windows 7*
I hope that can help.
At this point, I strongly recommend contacting your system manufacturer as they are more familiar with your system and how the components interact with each other, your computer manufacturer will be able to help you with the right configuration on your laptop.
