Product features
Multitasking Made Easy
With devices becoming more portable than ever, you can be limited to fewer video outputs and confined to your small integrated screen. This multi-stream transport hub solves that problem by enabling you to connect two separate displays to your USB-C computer, making multitasking much easier. Using this USB-C to dual DisplayPort monitor adapter, you can mirror your display onto additional monitors or stream independent content to each display, which makes it the ideal accessory for travel or hot-desking.Astonishing Picture Quality
MST technology uses your existing video card to minimize the use of system resources, while delivering UHD 4K resolutions for two monitors or displays simultaneously. With support for HD 1080p and UHD 4K, the dual-monitor splitter is perfect for all high-resolution applications such as graphic design and CAD drawing.Hassle-Free Setup
Multi-stream transport offers an easy setup, by natively working on any Windows device that supports DP Alt Mode over USB Type-C. This USB-C dual-monitor adapter is Thunderbolt 3 compatible, and offers plug-and-play installation with no drivers or software required. Additionally, this DP MST hub is powered by the USB-C port, meaning no external power cords are necessary. MSTCDP122DP is backed by a StarTech.com 3-year warranty, and free lifetime technical support.Key selling points
- MULTI-MONITOR CONFIGURATION: USB Type-C to Dual DisplayPort adapter/splitter drives up to 2x 4K 30Hz or 2x 1080p 60Hz DP monitors using a USB-C DP Alt-Mode port on Windows laptops; TB3/TB4/USB4 Compatible; Not compatible with macOS
- NO DRIVERS OR SOFTWARE: Increase productivity by adding two extended or mirrored displays to a Windows laptop; Utilize integrated or discrete GPU (Intel/AMD/Nvidia) capabilities enabling high performance graphics with minimal CPU usage
- HARDWARE COMPATIBILITY: Host system must support DP Alt Mode 1.2 / HBR2 / MST; Please verify maximum number of displays supported by your GPU; Some GPU chips (such as Intel HD Graphics) are only capable of supporting a maximum of three displays
- EXTRA-LONG CABLE: 1ft (30 cm) built-in cable for extended reach reduces USBC port/connector strain on 2-in-1 devices like Surface Pro 7, HP Elite x2/laptops on riser stands; Ideal for on-the-go travel use in office/home office/shared workspaces
- OUR ADVANTAGE: Included connectivity tools for IT Pro's and IT help-desk support teams with Windows Layout Utility which restores windows app locations when re-connecting the USBC to Dual DisplayPort Adapter
