How to fix HDMI port not working in Windows 10?

Issue: Hi, I have problem with the HDMI cable when trying to connect my laptop to a TV. I have Asus laptop and everything worked fine before. Could you help me to solve this issue on Windows 10? Many thanks.

Solved Answer

HDMI is a connection type that is often used to transmit video and audio data from a computer to a compatible device, such as another monitor, a TV, or a projector. First released in 2002 by high profile companies such as Sony, Philips, Toshiba, and others, this connection method became one of the main standards in the modern digital device era. HDMI has successfully replaced old connections such as VGA, bringing in much higher resolutions, crispier image, as well as the sound.

Despite many advantages, HDMI technology is not exempt from various issues, and the HDMI port not working is one of the most frequently encountered ones. Users reported that the computer simply could not establish a connection, while other times, they claimed that the sound was not present, despite the video working.

Most commonly, the issue is faced by laptop users who either recently upgraded to Windows 10 from an older version, although some users reported that even the brand new computers/laptops had the same problem and did not manage to fix HDMI port not working issue despite the efforts.

The very first thing that users should check is the HDMI cable itself, as it can simply stop working one day. For that, you either have to try an already working cable or purchase a new one from the shop. Nonetheless, the issue with HDMI not working typically does not lie there.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
