HDMI errors & connection problems [Troubleshooting Hub]

HDMI (High-Definition Multimedia Interface) is a audio/video interface for transmitting uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor or digital audio device.HDMI is a single cable to carry high-definition video, high quality multichannel audio, and control codes.

Sometimes an HMDI connection goes wrong and there are some steps you can take to fix it. Many users reported HDMI output problems that affect their windows versions from XP to Windows 10.

In the most common case, a driver incompatibility causes a missed audio or video output. If there’s no sound, video is missing, or simply your HDMI port is not working on PC, you can try to refresh your audio and video drivers.
