HDMI cable is a digital interface that transmits uncompressed video and audio data from a source device, such as a computer or Blu-ray player, to a compatible display device, such as a TV or monitor. HDMI cables are commonly used in home theater systems, as they can support high-definition video and audio formats. Checking an HDMI cable to ensure it is functioning correctly is a simple process that can be completed in a few minutes.
Examining an HDMI cable for damage is the initial step in testing it. Verify the cable’s ends for any physical harm, such as cuts, breaks, or loose connections. The cable should be replaced if you discover any damage. If the cable appears to be in good condition, the next step is to test its functionality.
