Expand Your Workstation Designed for those who want a one-stop upgrade for your USB 3.0 or USB-C laptop. The Plugable USB 3.0 Dual HDMI Laptop Docking Station for Windows, Mac, and ChromeOS (UD-3900Z) allows you to add dual HDMI monitors, and connect your peripherals, all through a single cable back to your laptop. Quickly come and go from your desk with ease. By connecting one cable to your laptop, you gain 10 extra ports of connectivity, making it easier to do more work in less time. Power users with dual monitors: The UD-3900Z is the dock you need to maximize your productivity and your workspace. An excellent option for adding two extra 1080p screens to your computer, even if it might otherwise only support one—like an M1, M2, or M3 MacBook. Great for business uses such as email, web applications, Microsoft office, and more. Featuring a vertical design, you can easily slip this dock between your monitors and save valuable desk space. Conveniently access the front USB and audio port for those devices you plug and unplug everyday. Note: This dock will not charge your laptop and will need your external charger to provide power to your system. This dock has two HDMI ports (not compatible with DisplayPort displays).
