Startech 3-Port Multi Monitor Adapter - DisplayPort 1.2 to 3x HDMI MST Hub
Increase productivity with multiple screens
The newest generations of computers are more portable than ever, which often means that you’re left with fewer video outputs and smaller integrated screens. This MST hub solves both of these problems by letting you connect three additional displays to your computer, which makes multitasking much easier.
Configure your displays for any environment
Using the MST hub, you can extend your desktop onto additional monitors and stream independent content to each display. You can also mirror the same image onto multiple HDMI televisions or projectors for remote viewing applications such as digital signage.
Enjoy amazing video quality without draining system resources
MST technology uses your existing video card to minimize the use of system resources while delivering Ultra HD 4K resolutions. This unprecedented performance makes MST perfect for high-resolution applications such as graphic design, gaming and medical imaging.
The MSTDP123HD supports plug-and-play installation for a hassle-free setup, and is backed by a StarTech.com 3-year warranty and free lifetime technical support.
Applications
Use one screen for reference data such as websites, while composing in another screen
Dock your DP 1.2 device and add three high-resolution displays at your workstation
Create a panoramic video wall for HDMI digital signage applications using your DisplayPort computer
Edit images, video or audio clips across three displays in any orientation or resolution
