Real HDMI 2.0 — Full 18Gbps Bandwidth
18Gbps bandwidth supports true 4K @ 60Hz, helping avoid the 4K @ 30Hz limitation of lower-bandwidth cables. The HD20B supports HDR, BT.2020 colour gamut, 24-bit colour depth, and 32-channel audio at up to 1,536kHz on compatible devices.
Braided Cable + Gold-Plated Astrum Moulded Connectors
The braided jacket offers a durable, tangle-resistant build with a premium feel. Gold-plated connectors help resist corrosion and maintain consistent signal transfer, while Astrum moulded connector housings provide a secure fit. SR stress relief at both ends helps protect the cable at common failure points.
EDID + DDC2B + Hot Swap
EDID and DDC2B support automatic device-to-device negotiation for the best available resolution and colour format. Hot Swap support allows you to connect and disconnect devices without restarting your system.
4K @ 60Hz + HDR + Wide Colour Gamut
Enjoy 4K at 60 frames per second, HDR contrast, 24-bit colour, and BT.2020 wide colour support on compatible displays and source devices. The HD20B is also backward compatible with HDMI 1.x devices and ports.
Works With HDMI Devices
