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.

For manufacturing and assembly environments, the company demonstrated its USB Type-C and USB4 production testing system. This tool performs physical layer analysis, specifically targeting signal integrity and detecting defects such as cold solder joints on connector pins. It also facilitates functional testing of USB4 operating modes to ensure cabling meets strict quality parameters.
Automation capabilities are integrated into these hardware systems, allowing engineers to bypass manual troubleshooting and debugging. By using automated test scripts, developers can run compliance sweeps and diagnostic cycles to retrieve results in seconds. This automation infrastructure is designed to reduce testing cycle times in both laboratory characterization and production line environments.
The testing solutions are certified by governing standards bodies, including VESA and HDMI. This certification ensures that devices under test comply with official specification profiles and perform reliably under varied operating conditions. Hardware manufacturers utilize these instruments to guarantee compliance and signal interoperability before releasing products to the commercial market.
