This USB to dual DisplayPort adapter lets you add two 4K 60Hz DisplayPort monitors to your Windows® or Mac computer. The adapter lets you use a single USB 3.0 port on your laptop to output dual 4K resolution at 60Hz to two independent displays. Simply plug the adapter into a USB 3.0 (5Gbps) port on your Windows or Mac system and connect your DisplayPort monitors to the adapter. The adapter lets you enjoy the picture quality of Ultra HD video across multiple screens, even if your system doesn't natively support 4K video output.
