## Long description

The StarTech MST14CD123DP is a USB-C to 3× DisplayPort multi-monitor adapter that converts a single USB-C or Thunderbolt port into three independent DisplayPort outputs. Designed for multi-display workflows, the adapter enables extended or mirrored desktops and supports up to 4K at 60Hz per compatible output when used with a host and cables that provide sufficient bandwidth. Its compact design and Plug-and-Play operation make it suitable for workstations, trading desks, design studios and monitoring stations that require multiple DisplayPort connections from a single USB-C port.
Advantages
The adapter provides a simple way to multiply DisplayPort outputs from a single USB-C connection without additional docking hardware. It supports high-resolution output to multiple monitors, reducing cable clutter and simplifying multi-display setups. Built with compatibility for DisplayPort displays, it enables flexible display arrangements (extended or mirrored) and maintains support for 4K at 60Hz on compatible displays, depending on host capability and cable quality.
Suitable for
 Multi-monitor productivity setups (extended desktops)
 Trading and financial workstations with multiple screens
 Graphic design and video editing with high-resolution displays
 Monitoring stations and control rooms requiring several DisplayPort outputs
Key specifications
 Input interface: USB-C / Thunderbolt compatible port
 Output interfaces: 3 × DisplayPort outputs
 Max resolution per output: up to 4K (3840×2160) at 60Hz, depending on host and cable
 Video mode: supports extended and mirrored display configurations
 Power: powered via host USB-C port (no separate power supply required under normal operation)
 Form factor: compact external adapter for desktop use
How to use
Connect the adapter to a compatible USB-C or Thunderbolt port on the host computer, then connect up to three DisplayPort monitors to the adapter outputs using DisplayPort cables. Configure the display arrangement in the host operating system display settings to set extended or mirrored mode, adjust resolution and refresh rate as supported by the host GPU and monitor capabilities. Ensure that the host port supports the necessary display bandwidth and that DisplayPort cables and monitors are rated for the intended resolution and refresh rate.
Usage recommendations
For reliable 4K at 60Hz performance on multiple displays, use high-quality DisplayPort cables and verify that the host USB-C/Thunderbolt port and graphics hardware support the combined bandwidth. If the host cannot provide sufficient bandwidth, reduce resolution or refresh rate per display. Place the adapter where ventilation is adequate and avoid using passive USB-C extension cables that may limit signal integrity.
