HDMI 2.2 Cable Certification presented the latest developments in high-bandwidth connectivity and compliance testing at Computex 2026. Mike, who oversees HDMI cables and the PC program, outlined the upcoming release of the Compliance Test Specification (CDS) scheduled for the third quarter of this year, which will govern the verification of next-generation cables.

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

The current HDMI certification landscape includes Premium HDMI cables, which support 4K resolution at 60Hz and 18Gbps bandwidth, and Ultra High Speed HDMI cables, which support up to 48Gbps bandwidth for 8K displays. Additionally, prototypes of the new Ultra 96 HDMI cables were showcased to meet growing industry demand for higher data transfer rates.
Under the HDMI testing program, every cable length must undergo individual testing at an Authorized Test Center (ATC) to ensure signal compliance. Consumers can verify whether a specific cable has successfully passed certification by scanning the package’s QR code with a mobile device to access the model number, speed class, and cable length details.
The certification framework is also adapting to accommodate active cable implementations, including Active Optical Cables (AOC) and active copper cables that integrate internal signal booster chipsets to maintain signal integrity over longer spans. The incoming specifications will define precise testing methods to evaluate active signal processing without introducing delay.
To guarantee consistent quality after initial certification, an audit process is performed where cables are acquired directly from retail markets and submitted to testing laboratories for re-evaluation. This ensures that mass-market cables continue to satisfy the original performance requirements and technical specifications defined by the compliance program.
