HDMIulkopääte

HDMIulkopääte is a Finnish term used to describe HDMI endpoint devices—the components that receive an HDMI signal from a source such as a Blu-ray player, computer, or game console. In typical setups, the endpoint is a display device like a TV, computer monitor, projector, or an AV receiver that handles the final presentation of video and audio to the user. The term helps distinguish the receiving end from the source in a cable-based AV chain.

An HDMIulkopääte engages in EDID (Extended Display Identification Data) negotiation with the source to determine supported resolutions, frame rates, color depths, and audio formats. It may also be subject to HDCP (High-bandwidth Digital Content Protection) checks to maintain content protection. Depending on the device, an endpoint may merely display the signal, or route it to built-in speakers, external audio systems, or other processing blocks. Some endpoints can also pass through or downmix audio while displaying video.

The capabilities of an HDMIulkopääte depend on the HDMI version it supports (for example HDMI 1.4, 2.0, or 2.1) and its hardware design. Higher bandwidth versions enable features such as 4K resolution at higher refresh rates, HDR, and wider color spaces. Compatibility with specific features is determined by the endpoint, the source, and the cables used.

In Finnish-language contexts, the term is used to refer to the terminating end of an HDMI connection, in contrast to sources (lähteet) or signal-splitting or switching devices (jakajat or vaihtimet). Common examples of HDMIulkopääte include televisions, computer monitors, projectors, and home-theater receivers.
