This VESA-certified DisplayPort 1.4 cable features a special A.I.S. (anti-interference shielding) design, with multi-layer metal shielding in the connector and additional sheathing of the copper conductors – for optimum interference protection With 32.4Gbit/s (HBR3) of bandwidth, this DisplayPort cable supports UHD (Ultra HD) resolutions of up to 8K (7680×4320), gaming-ready frequencies of up to 144Hz, 165Hz, or even 240Hz at 1440p, HDR10 video & 7.1 surround sound audio signals As an official VESA member, we’ve manufactured and tested this cable to VESA specifications – therefore pin 20 isn’t connected to prevent damage due to short circuits. And with their locking mechanism, the connectors deliver a rock-solid connection No risk: 36 months manufacturer warranty This DisplayPort monitor cable (male to male) works bidirectionally with PCs, laptops/notebooks, monitors, and projectors. And thanks to G-Sync/FreeSync support, the monitor's refresh rate is synced perfectly with the graphics card’s video signal
