On displays three and four, tap into the power of Multi-Stream Transport (MST) Alt Mode. All four screens look great with resolutions up to 1080p at 60Hz. Also works as a triple display docking station (sometimes referred to as a triple monitor docking station). The UD-3900C4 is a multi monitor docking station. Featuring a USB-C port with 20W charging for your newer peripherals, and 4x USB 3.0 ports for your legacy devices - all capable of data transfer speeds up to 5Gbps - so you'll always have room to plug in and power up. It also has room for extra storage or a convenient way to download pictures through the onboard SD card reader. And with 96W charging for your laptop, an Ethernet port, a 3.5mm audio-out jack, and a 3.5mm audio-in jack, the UD-3900C4 has everything you need to get work done. Get the full experience with Windows 10 or later. Requires compatible USB4, Thunderbolt 4, Thunderbolt 3, USB-C system. As a MacBook docking station (macOS 10+) DisplayPort MST is not supported so the fourth display can only be mirrored. Requires DisplayLink Drivers - automatically downloaded with Windows update.
