Product Overview The Lightware HDMI-4K Manager (part number 91330009) is a professional-grade HDMI signal manager designed for installations that require active signal conditioning, format conversion, and distribution control in a single unit. It consolidates EDID management, HDCP handling, and signal reclocking into a compact chassis suited for permanent installation in AV racks. Product Description The HDMI-4K Manager handles 4K/60Hz at 18 Gbps with HDCP 2.2, delivering compliant signal management across HDMI 2.0 infrastructure. It is engineered for environments where the interaction between source devices, control systems, and displays needs to be tightly managed — particularly where EDID mismatches or HDCP negotiation failures cause recurring operational issues. Lightware's signal management approach addresses these failure points at the hardware level rather than requiring software workarounds. The unit is configurable via Lightware Device Controller software over Ethernet, allowing remote EDID programming and real-time signal status monitoring. Available from Creation Networks.

Passive splitters and basic active splitters cannot resolve EDID mismatches or HDCP negotiation failures — two of the most common causes of no-signal conditions in installed AV systems. The HDMI-4K Manager handles both at the hardware level, with user-programmable EDID and independent HDCP authentication, eliminating the need for software workarounds or repeated power cycling. Can EDID profiles be stored and recalled? Yes. Custom EDID profiles can be programmed and stored in the unit using Lightware Device Controller software, and emulated to the source device regardless of which displays are physically connected downstream. What control protocols does it support? The unit supports Ethernet-based control via Lightware Device Controller and RS-232 serial control, making it compatible with major third-party control systems including Crestron, AMX, and Savant. Does it support HDR content? Yes. The HDMI-4K Manager passes HDR metadata within the HDMI 2.0 signal, supporting HDR10 and compatible formats on connected displays. Is it suitable for rental and staging use? Yes. The ability to quickly reprogram EDID profiles via software makes it practical for rental and staging environments where display configurations change between events. What audio formats pass through? All audio formats within the HDMI 2.0 signal pass through unmodified, including Dolby Atmos, DTS:X, and multi-channel PCM up to 192 kHz.
