HDMI Connectors: China Sourcing Reference
1 resources tagged with "Hdmi"
HDMI connectors sourced from China carry a licensing wrinkle most buyers miss: the HDMI spec is administered under license with a per-unit royalty and Adopter agreement, which is why some products and quotes quietly avoid the logo. Version capability is set by bandwidth — HDMI 2.0 carries 18Gbps (4K60), HDMI 2.1 up to 48Gbps (4K120/8K) — and at those speeds the connector's impedance control and shielding decide pass or fail. The common failure mode is a connector that passes a 1080p bench test but shows sparkles or signal dropout at 4K, which only surfaces under proper high-speed testing.
When sourcing HDMI, you are dealing with both a licensed standard and a high-speed RF interface, so the supplier's licensing status and the part's controlled impedance both matter. We check whether the product needs HDMI Adopter compliance, and we verify high-speed integrity at the target resolution rather than trusting a low-resolution demo.

FAQ
Do I need an HDMI license to sell HDMI products?
Products using HDMI technology generally require an Adopter agreement and per-unit royalty to use the HDMI name and logo legally. Many low-cost China suppliers ship unlicensed parts; if you brand and import the product, the licensing obligation can fall on you.
How do I make sure an HDMI connector handles 4K?
Confirm the connector and cable assembly are rated for the target bandwidth (18Gbps for 4K60, 48Gbps for 4K120/8K) and test at that resolution, not just 1080p. Sparkles, blackouts, or HDCP handshake failures at high resolution point to poor impedance control or shielding.
