Product Features
Technical Overview
This adapter is built around the DisplayPort 1.4 standard, incorporating Display Stream Compression (DSC) to handle the high bandwidth demands of triple 4K60Hz output. DSC is a visually lossless compression technology that allows for higher resolutions and refresh rates without compromising image quality. The hub supports HDR (High Dynamic Range) content passthrough, providing greater contrast and color depth for compatible monitors and media.
Compatibility is centered on Windows PCs with a USB-C port that supports DisplayPort Alternate Mode. For full triple 4K60Hz performance, the host device requires a discrete GPU or a 12th Gen (or newer) Intel processor with integrated graphics that feature DP 1.4 with DSC. The hub is also compatible with Thunderbolt 3, Thunderbolt 4, and USB4 hosts that support DP Alt Mode. It includes support for HDCP 2.2 for protected content playback and delivers 2-channel digital audio alongside video.

Deployment / Use Cases
This adapter is purpose-built for environments where screen space directly translates to efficiency and capability. It enables users to break free from the limitations of a single laptop screen, creating a command-center experience wherever they work.
For IT support teams and help desks, the included Windows Layout Utility is a significant productivity tool. It remembers application window positions across disconnects and reconnects, allowing technicians to seamlessly transition between mobile work and a docked multi-monitor station without manually rearranging their workspace. This is invaluable for professionals who frequently move between meeting rooms and their desks.
Professional Workspace Expansion
Ideal for financial analysts, software developers, content creators, and data scientists who rely on multiple applications and data sources visible simultaneously. The triple 4K support allows for detailed spreadsheet analysis, code editing alongside documentation, or video timeline editing with full tool palettes.
Mobile & Flexible Office Setup
Perfect for hot-desking, home offices, or consultants who travel between client sites. The compact, cable-integrated design fits easily in a laptop bag. Users can quickly create a triple-monitor workstation with any compatible Windows laptop and three DisplayPort monitors, enhancing productivity in temporary or shared workspaces.
Physical Profile
The hub features a compact, low-profile gray chassis designed to sit discreetly on a desk or mount behind a monitor. Its dimensions (4.10" W x 1.70" L x 0.60" H) make it highly portable. The integrated 1-foot cable includes strain relief to protect the connection point on your laptop, a critical feature for devices like the Microsoft Surface Pro or HP Elite x2 that are often used in tablet or elevated positions. Weighing just 1.80 oz, it adds negligible bulk to any mobile kit.

User Manual
FAQ
Is this adapter compatible with macOS or Chromebooks?
No, this adapter is not compatible with macOS or Chromebooks. It is designed specifically for Windows-based systems. Compatibility requires a Windows PC with a USB-C port that supports DisplayPort Alternate Mode. For full triple 4K60Hz support, the host needs a discrete GPU or a 12th Gen (or newer) Intel processor with integrated graphics featuring DP 1.4 and DSC.
Does it require a separate power supply or external drivers?
The hub is bus-powered, drawing all necessary power directly from the host computer's USB-C port, so no separate power adapter is required. For basic display extension or mirroring on a compatible Windows system, it operates as a plug-and-play device with no additional drivers needed. StarTech.com does provide a Windows Layout Utility software to enhance the user experience by remembering window positions.
What is Multi-Stream Transport (MST) and why is it important?
Multi-Stream Transport (MST) is a DisplayPort technology that allows a single DisplayPort output to drive multiple independent displays through a daisy-chain or hub. This hub uses MST to split the signal from one USB-C/DP port into three separate display streams. This is crucial for creating a true multi-monitor workstation from a single laptop port, as it allows each monitor to act as an independent desktop extension rather than just a mirrored copy.
Can I use this with a Thunderbolt 3 or Thunderbolt 4 laptop?
Yes, the hub is fully compatible with Thunderbolt 3 and Thunderbolt 4 laptops, as well as USB4 hosts, provided they support DisplayPort Alternate Mode over the USB-C/Thunderbolt port. This makes it an excellent choice for users with modern high-performance laptops from brands like Dell, HP, Lenovo, and Microsoft that feature Thunderbolt ports.
What is included in the box with the adapter?
The product is packaged as a single unit. The package includes the StarTech.com MST14CD123DP USB-C to 3x DisplayPort MST Hub itself, which has the integrated 1-foot cable. no additional cables, manuals, or accessories are listed as standard package contents. For detailed specifications and support, refer to the manufacturer's brochure available online.
What refresh rate or brightness details are available?
