StarTech.com 3-Port MST Hub: DisplayPort to Triple HDMI 4K 60Hz

Unlock expansive multi-monitor productivity with the StarTech.com 3-Port MST Hub. This DisplayPort 1.4 MST (Multi-Stream Transport) adapter turns a single DP source into three HDMI displays, delivering impressive vertical real estate for professionals, designers, traders, and creators who demand immersive, borderless workflows. Designed for Windows environments, it leverages DSC (Display Stream Compression) and modern GPU capabilities to achieve 4K at 60 Hz on each screen when the right hardware is in place. While it shines with DP 1.4/DSC-enabled setups, it also remains functional on DP 1.2 hosts at reduced resolutions or refresh rates, offering flexibility for a range of systems.

• Drive three HDMI displays from one DisplayPort 1.4 source using MST technology, enabling true triple-monitor configurations for enhanced productivity and immersive workflows.
• Supports up to 4K resolution at 60 Hz on each HDMI output when paired with a DSC-enabled GPU and a DP 1.4 host, providing crisp detail, accurate color, and smooth motion across all displays.
• Windows-only compatibility ensures optimized driver support and seamless integration with modern discrete GPUs and contemporary Intel processors (12th generation and newer) that include DP 1.4 and DSC support for triple 4K60 capabilities.
• Backward compatibility with DP 1.2 hosts allows flexible upgrading paths, delivering usable multi-monitor setups at lower resolutions or refresh rates when DSC is not available.
• Compact, dependable design designed for professional environments, enabling a tidy desk setup while maintaining strong signal integrity across three HDMI outputs for demanding workloads.

how to install StarTech.com 3-Port MST Hub

• Verify your computer has a DisplayPort 1.4 output and a compatible discrete graphics card with DSC support to reach 3x4K60 on three HDMI displays.
• Connect the DisplayPort cable from your PC to the DP input on the MST hub.
• Attach three HDMI cables from the hub’s HDMI outputs to your three HDMI displays.
• Power on all displays and boot your Windows system. If necessary, install or update graphics drivers to ensure MST and DSC features are recognized by the OS.
• Open Windows Display Settings to arrange the three monitors, extend the desktop, and customize resolution and orientation for each screen. Ensure that the GPU and driver support MST configurations for triple-4K60 output.

Frequently asked questions

• Can I run three 4K60 displays from a single DisplayPort connection? Yes, but it requires a DP 1.4 host with DSC and a compatible discrete GPU to enable triple 4K60 outputs. On DP 1.2 hosts, triple 4K60 is not supported and you may experience lower resolutions or refresh rates.
• Is this adapter compatible with macOS or Linux? The product is described as Windows-only; there is no official macOS or Linux support documented by StarTech for triple-4K60 configurations.
• Do I need extra software to use the hub? Windows-based MST configurations typically rely on GPU drivers and Windows Display Settings; no additional third-party software is required for basic operation, but updated drivers are recommended for best results.
• What happens if my GPU or motherboard doesn’t support DSC? You may still use the hub, but triple 4K60 output will not be possible; you would be limited to fewer monitors or lower resolutions/refresh rates depending on your hardware capabilities.
• Is the hub a plug-and-play solution? It is designed to be straightforward to set up on Windows systems with compatible hardware, but optimal performance depends on matching a DSC-enabled DP 1.4 host and GPU configuration.
