The limited number of ports on your laptop makes it lighter and thinner, which is great when you’re on the go. But when you’re at your desk and you need access to extra screens and all of your peripherals, the UD-3900C4 has you covered.
A universal docking station for laptops that extends your productivity across up to four screens. The unique display configuration on Plugable's UD-3900C4 utilizes DisplayLink technology to deliver a crisp picture on displays one and two. On displays three and four, tap into the power of Multi-Stream Transport (MST) through DisplayPort (DP) Alt Mode. All four screens look great with resolutions up to 1080p @ 60Hz.
The UD-3900C4 is a multi monitor docking station. Featuring a USB-C port with 20W charging for your phone or 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 quad experience with Windows 10 or later and ChromeOS 100 or later.
Requires compatible USB4, Thunderbolt 4, Thunderbolt 3, USB-C system.
Requires installation of DisplayLink Drivers—automatically downloaded with Windows update.
For macOS 10+, DisplayPort MST is not supported so only three unique extended displays are supported.
Not the right fit for gaming and HDCP (copy-protected) content playback from Blu-ray/Netflix/Prime/ iTunes/Hulu/etc.
