Q: What is UL 4299?

A: UL 4299 is a soon-to-be published certification program from UL (Underwriter’s Laboratories) that will focus on the electrical performance and safety testing of communication cables intended to support HDBaseT transmissions. The HDBaseT Alliance is an organization advocating the transmission of high-definition video and audio, Ethernet and controls for up to 100 meters. UL 4299 will test not only for support of the HDBaseT transmission itself, but for the cable’s ability to safely accommodate up to 100 watts of DC power.
