Certified 4K cables are evaluated according to the UL 4000 specification and meet the requirements for their associated data rate test. This is UL's first performance certification program for 4K cable products, including a comprehensive tracking and market surveillance program, and a UL anti-counterfeiting program to help ensure a healthy and sustainable compliance supply chain. The growing 4K display technology is widely accepted in the market. Brands, installers, retailers and end users are increasingly concerned about the reliability of cable data transfer rates for connecting 4K devices. Attaching a globally recognized and trusted UL Mark to cable products or their packaging allows customers and consumers to have more confidence and confidence in the quality of the cables they purchase.
