About

HDMI (High-Definition Multimedia Interface) is a widely used interface for transmitting audio and video signals between devices and displays. Many PCs now include the ability to output audio/video directly to an HDMI port. A variety of adapters and techniques exist for bridging other popular digital display standards (, for example) with HDMI sources or inputs.

Questions should be tagged if they involve a need to understand or troubleshoot connecting to / using a HDMI input, output, or adapter with any computer or related device.
