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 hardware features a robust IP69K ingress protection rating, making it completely water- and dust-proof. This design incorporates specialized IP69K-rated connectors that can be sealed with rubber blockers when not in use to maintain protection. For alternative deployment requirements, an IP65 version is also available, which utilizes standard connectors secured by a specialized rubber gasket sealing mechanism.
System configurations include integrated panel PCs running either Windows on Intel processors or Android on ARM-based architectures, as well as standalone monitor options. The displays incorporate capacitive touch technology and optical bonding. This construction, paired with high-brightness panels, ensures outdoor visibility, durability under direct sunlight, and resistance to ultraviolet and infrared radiation.
To support multi-media requirements in wet conditions, the units are equipped with weather-sealed waterproof speakers. The robust chassis and sealing allow the systems to withstand high-pressure, hot-water washdowns, persistent humidity, and heavy dust accumulation without degradation of performance.
