HDMI Forum MOI Verification Testing & Plugfest

Dec 8, 2025 - Dec 12, 2025 (Taipei)

The HDMI Forum was formed to foster broader industry participation in the development of the next generation of the HDMI Specification and to support an ecosystem of interoperable HDMI-enabled products. The HDMI Specification combines uncompressed high-definition video, multi-channel audio, and data in a single digital interface to provide crystal-clear digital quality over a single cable. The organization brings together the world’s leading manufacturers of consumer electronics, personal computers, mobile devices, cables and components.

MOI Verification

The MOI Verification Event is intended as an opportunity for end product manufacturers and test equipment manufacturers to quickly and effectively verify that MOIs can be executed, to make sure that multiple test equipment implementations correlate with each other, and interoperability can be verified among end products. The MOI Verification will be testing Methods of Implementation for test procedures in the latest GCTS 2.1 and proposed tests for GCTS 2.2. The HDMI 2.0/2.1/2.2 MOI Verification Testing is only open to HDMI Forum members.

Plugfest

The HDMI 1.4/2.0/2.1/2.2 Plugfest is open to any interested parties with HDMI Sink/Source/Repeater products or prototypes, and is intended for unofficial device-to-device interoperability testing. The Plugfest will provide for compatibility testing between Sources, Repeaters, and Sinks, with features tested as decided by the participants. Features first introduced in HDMI 2.1/2.2 will be given priority; as a result, there may be limited testing opportunities for TMDS-only devices.

Symbiosys Alliance member Unigraf is participating in this event.

Unigraf specializes in video electronics testing tools for HDMI®, DisplayPort™, and USB Type-C® interfaces.
