DisplayPort 1.2 to 3-Port MST Hub - Split to Three 4K/1080p Displays

Our review of this DisplayPort 1.2 to 3-Port MST hub finds it most useful for power users who need to expand one DisplayPort output into three independent displays. The single biggest reason to consider it is its support for Multi-Stream Transport (MST), which lets a compatible DisplayPort 1.2 GPU drive multiple monitors in Extend or Video Wall modes. Setup is straightforward for Windows systems with MST-capable graphics cards, but note the device does not support MacOS and requires USB 3.0 bus power and a GPU that can address three external screens.

Key Features

• 3-Port MST Split: Connect three DisplayPort monitors to one DisplayPort 1.2 output, allowing extended desktops or panoramic layouts for productivity and digital signage.
• Multi-Mode Display: Offers Mirror, Extended, and Video Wall modes so displays can show identical content, independent content, or combine into one large workspace.
• 4K and 1080p Support: Handles a single 3840x2160@60Hz, dual 3840x2160@30Hz, or triple 1080p outputs within DisplayPort 1.2 bandwidth limits for flexible resolution arrangements.
• USB Bus Powered: Uses USB 3.0 power so no external power brick is required, provided the host USB port supplies adequate current.
• Compatibility with MST GPUs: Works with DisplayPort 1.2 MST graphics cards and technologies such as AMD Eyefinity and NVIDIA Surround for multi-monitor setups.

Who It's For

This hub is aimed at Windows desktop or laptop users with a DisplayPort 1.2 output and a graphics card capable of addressing more than three external displays, such as certain AMD or NVIDIA cards. It is a practical choice for content creators, traders, and digital signage installers who want a cost-effective way to add two extra screens without replacing the GPU.

It is not suitable for MacOS users, systems that cannot provide USB 3.0 bus power, or setups relying on integrated Intel graphics limited to three external screens in total. Buyers unsure about GPU compatibility should contact support before purchasing to avoid configuration issues.

Pros & Cons

Pros

• Expands a single DisplayPort 1.2 output into three independent DP monitors using MST technology.
• Supports high resolutions including single 4K@60Hz or dual 4K@30Hz depending on configuration.
• USB 3.0 bus power removes the need for an external power adapter when the host provides sufficient current.
• Compatible with common multi-monitor technologies like AMD Eyefinity and NVIDIA Surround.

Cons

• No support for MacOS, limiting use to compatible Windows and MST-capable GPUs.
• Some users report occasional signal or longevity issues, and overall performance depends on the host GPU and total DisplayPort 1.2 bandwidth.

Our Verdict

This MST DisplayPort hub is a solid, cost-effective tool for building multi-monitor workstations when paired with a capable DisplayPort 1.2 GPU and a USB 3.0 power source. It delivers flexible display modes and high-resolution support, making it good value for Windows users who need extra screens; however, avoid it if you rely on MacOS or a GPU that cannot drive three external displays.

Frequently Asked Questions

Does this work on MacOS?
No. This hub does not support MacOS and requires a Windows or other MST-capable host.

What power is required?
The hub requires USB 3.0 bus power from the host; USB 2.0 typically will not supply enough current.

Will it run three 4K displays?
No. DisplayPort 1.2 bandwidth limits it to a single 4K@60Hz, dual 4K@30Hz, or triple 1080p configurations.
