  • StarTech MST14DP123DP 3-Port DisplayPort 1.4 Splitter, DisplayPort to 3x DP Multi-Monitor Adapter, Triple 4K Computer MST Hub, USB Bus-Powered - Windows Only

    This 3-port DisplayPort MST hub lets you create a high-performance workstation by connecting three DisplayPort monitors to your DisplayPort device, helping to increase and maximize your productivity. The multi-monitor splitter supports High Dynamic Range (HDR) and provides sharper images with enhanced video.


    Incredible Picture Quality

    Supporting four times the resolution of 4K, this DP 1.4 MST hub delivers the stunning quality of UHD at resolutions up to 7680×4320 at 30Hz on a single monitor and supports multi-monitor applications at lower resolutions and refresh rates, enabling a dynamic work environment whether you're in the office, at home or traveling.

    Multi-Tasking Made Easy
    This DisplayPort to 3x DisplayPort MST hub enables you to connect three displays to your DP computer, making multi-tasking much easier. Using this multi-monitor video splitter, you can mirror your display onto multiple monitors, stream independent content to each display or extend your screen to create a video wall effect.

    Hassle-Free Setup
    Multi-stream transport offers an easy setup, by natively working on any Windows device. It offers plug-and-play installation with no drivers or software required. Additionally, the DisplayPort MST hub is bus-powered (with the included micro-USB cable), creating an ultra-portable solution for business and IT professionals.

    MST14DP123DP is backed by a StarTech.com 3-year warranty, and free lifetime technical support.
