Hi, my name is Talita. I'm an Independent Advisor and a Microsoft user like you. I'll be glad help you today.
Please see if these tips can help you:
- see if the cable is in a comfortable position, not being "forced"
- the resolution of one screen may be different from another so try to match the quality and aspect ratio on the laptop to the limitations and measurements of the TV and the signal can be restored.
- try going to Control Panel> Hardware and Sound> Sound> Manage audio devices. Check that the HDMI output is enabled and that the volume is high enough.
Firmware
If the HDMI cable appears to transmit neither audio nor video to the TV, the problem may be with the firmware - operating instructions programmed directly into the hardware of an electronic device. In that case, simply connect the TV or device in question to the internet and download the latest firmware update.
If the problem does not resolve, let me know to continue with your question
I hope this helps. Please let me know if you have any more questions.
Sincerely
Talita C.
