HDMI Passive Adapters

HDMI Passive Adapter Compliance Program

To meet the growing needs of the HDMI ecosystem, HDMI Licensing Administrator, Inc. (HDMI LA) has released a new Implementation Guideline for HDMI® Passive Adapter. This document outlines suggested implementation for HDMI Passive Adapters.

HDMI Passive Adapters are passive interconnect components that typically provide coupling between HDMI Plug to HDMI Receptacle and convert connectors from HDMI Type A to Type A, Type C or Type D connector types. Based on usage case, there are different form factors of these components such as “small attachment” or “pig tail” for exchange of connector type on HDMI Cable Assemblies or Devices. Additionally, there may often be an “adjustable cable” type for wall installations or for tight spaces such as wall mounted displays.

These enable users to have flexibility when installing their HDMI Products in situations and environments where making the connection can pose a challenge. All HDMI Passive Adapters are designed for specific use cases and will have usage limitations that are product-specific, as defined by the HDMI Passive Adapter manufacturer.

HDMI Passive Adapters are considered in compliance only when they meet all the requirments of the Implmenetation Guideline for HDMI Passive Adapter
