Four-pack HDMI coupler for cable extension

This LUOM pack contains four female-to-female HDMI couplers that join two male-ended cables into a single longer run. Each adapter also converts a male HDMI port into a female socket, letting you connect devices that only have a male plug. The gold-plated contacts resist corrosion and maintain signal integrity across the joint.

HDMI 1.4 bandwidth limits resolution and refresh

The couplers comply with the HDMI 1.4 standard, so the maximum supported timing is 4K at 60 Hz. Resolutions such as 3840x2160, 2560x1600, 2560x1440, 1920x1200 and 1080p are passed through, but higher refresh rates or newer HDR formats that require greater bandwidth are not supported. Audio Return Channel, HDMI Ethernet Channel, 3D video and 7.1 or 5.1 Dolby digital audio are all carried across the link.

Gold-plated connectors for repeated mating

Gold plating on every contact reduces oxidation and ensures reliable conductivity after many insertions. The compact barrel design adds minimal strain to the connected cables and fits behind wall-mounted displays or inside tight AV racks. Buyers who need HDMI 2.0 or 2.1 bandwidth for 4K at 120 Hz or 8K signals should choose a different adapter class.
