USB C to 3 HDMI Splitter MST Hub - Triple 4K Extension

In this review the USB C to 3 HDMI Splitter MST Hub proves to be a focused solution for users who need to expand a Windows laptop or desktop to three external displays. The biggest reason to buy is its ability to drive three extended monitors using MST when paired with a DP Alt 1.4 capable port and a compatible GPU or recent Intel CPU, which makes it a practical tool for traders, developers, and multitaskers who want a larger desktop without adding multiple discrete adapters.

Key Features

• Triple Monitor Support: Adds up to three HDMI monitors in extended or video wall mode to increase desktop workspace and productivity.
• High Resolution: Supports up to 4K@144Hz on a single screen and simultaneous triple output at 4K@60Hz when the host supports DP Alt 1.4 with DSC.
• Windows MST Compatibility: Uses Multi-Stream Transport on Windows systems to enable independent displays rather than simple mirroring.
• Plug and Play: No drivers or external power required, making setup straightforward when connected directly to a compatible USB-C port.
• Durable Build: Compact aluminum housing, gold-plated plugs and a flexible 45cm cable provide reliable physical connections for frequent use.

Who It's For

This hub is best for Windows users who need a multi-monitor workstation without installing separate display cards or multiple adapters, especially anyone with a laptop that supports DP Alt 1.4 / Thunderbolt 4 or a desktop with a GPU that can handle three displays. It suits programmers, analysts, creative professionals and multitaskers who want true extended desktops.

It is not a good choice for most macOS users who require extended displays because macOS does not support MST and will only mirror outputs; also, users with older USB-C ports or GPUs that lack DP 1.4/HBR3/MST support should look for alternate solutions or verified docking stations that use the host GPU differently.

Pros & Cons

Pros

• Can drive three independent HDMI monitors on supported Windows hosts, improving multitasking.
• High-resolution capability with up to 4K@60Hz across three screens when host and GPU support DP Alt 1.4 + DSC.
• Simple plug-and-play operation with no drivers or extra power required for most setups.
• Robust physical design with aluminum case, gold-plated plugs and a flexible cable for durability.

Cons

• macOS only allows mirrored displays because it lacks MST support, limiting usefulness for Apple users.
• Requires a compatible USB-C port and sufficient GPU/display output support to reach top resolutions, so older systems may not achieve 4K@60Hz on all three screens.

Our Verdict

The USB C to 3 HDMI Splitter MST Hub is a practical value for Windows users who want to expand to three independent HDMI monitors without extra drivers or power.

Frequently Asked Questions

Will this work with macOS?
macOS does not support MST, so the hub will only mirror displays on Apple systems rather than provide extended desktops.

Do I need an external power supply?
No external power is required; the hub draws power from a compatible USB-C port but must be connected directly to the computer port, not through another adapter or hub.

What does my computer need to reach 3 x 4K@60Hz?
Your host must support DP Alt 1.4 with DSC and have a GPU or Intel CPU (12th gen or newer recommended) capable of driving three displays simultaneously.
