StarTech.com MST14CD123HD USB-C to Triple HDMI MST Hub

3x HDMI OutputsUp to 3x 4K 60HzDP 1.4 + DSCHDR + HDMI AudioWindows Only

The StarTech.com MST14CD123HD is a 3-port USB-C MST hub that turns one USB-C port into three independent HDMI outputs, driving up to three 4K 60 Hz monitors in extended or mirrored mode — a driverless way to build a multi-screen Windows workstation. Sold under part number MST14CD123HD (EAN 0065030887663), it uses the host’s own GPU via DisplayPort 1.4 Alt Mode with DSC. Typically in stock with fast delivery across Cyprus.

Compatibility note — please read
Windows only — not compatible with macOS. Triple 4K 60 Hz requires a Windows host with DisplayPort 1.4 Alt Mode and DSC — a discrete GPU or Intel 12th-gen (and newer) processor, including Thunderbolt 3/4 and USB4 laptops. On older DisplayPort 1.2 hosts the hub still works, but at lower resolutions or fewer 4K screens (for example three displays at 1080p). This is a video adapter only — it has no USB data ports, Ethernet or charging.

Key Features

 
Three HDMI Displays
Add up to three HDMI monitors from a single USB-C port using Multi-Stream Transport (MST), in extended mode for more workspace or mirrored mode for presentations.
 
Up to 4K 60Hz Each
With a DisplayPort 1.4 host and DSC, drive all three displays at a crisp 4K 3840 × 2160 60 Hz, with HDR and 2-channel HDMI audio.
 
Driverless & Compact
No software to install — the hub uses your PC’s own GPU. A 30 cm attached cable and 72 g body make it easy to carry between desks.

Frequently Asked Questions

Does it work with a MacBook or macOS?
No. The MST14CD123HD is Windows only and is not compatible with macOS, because Apple systems do not support MST for multiple extended displays. Use it with a Windows laptop or desktop.
What do I need for three 4K 60Hz monitors?
A Windows host with DisplayPort 1.4 Alt Mode and DSC — that means a discrete GPU or an Intel 12th-gen (or newer) processor, including Thunderbolt 3/4 and USB4 laptops. Older DP 1.2 hosts run the displays at lower resolutions.
Can I extend my desktop across the three screens?
Yes. It supports both extended mode (each monitor shows a different part of your desktop) and mirrored mode (the same image on all screens), configured in Windows display settings.
Does it have USB ports or charging?
No. This is a dedicated multi-monitor video adapter with three HDMI outputs only — it does not add USB data ports, Ethernet or Power Delivery. For those, choose a USB-C docking station.
Singular Expert Insight
The MST14CD123HD is the specialist choice when you specifically need three HDMI monitors from one USB-C port on a Windows PC — traders, engineers and analysts who live across multiple screens. Because it relies on MST, confirm your laptop is Windows with DP 1.4 and DSC before buying; Mac users cannot use it. If you also need USB ports, Ethernet or charging, pair it with, or choose instead, a full USB-C docking station.

Buyer’s Guide

Buy it if
You run a Windows PC with DP 1.4 and DSC and want three extended HDMI monitors (up to 4K 60Hz) from one USB-C port.
Skip it if
You use a Mac, or need USB ports, Ethernet or laptop charging — this is a Windows-only, video-only MST hub.
Also consider
A USB-C docking station if you need USB, Ethernet and charging alongside video, or a dual-HDMI adapter for two screens.
