## Long description

The StarTech.com Multi Monitor Adapter 3 Port DisplayPort 1.4 (MST14DP123DP) is a compact DisplayPort MST hub that lets you connect up to three DP monitors to a single DisplayPort source on a Windows computer. The adapter supports DisplayPort 1.4 and High Dynamic Range (HDR), enabling high-resolution video output and flexible multi-monitor configurations for productivity-focused workstations.
Advantages
This 3-port DisplayPort splitter supports resolutions up to 7680×4320 (8K) at 30Hz on a single display when both source and displays support DP 1.4. It also supports multiple monitor layouts at lower resolutions and refresh rates, including 4K and 1080p across three screens. The hub is bus-powered via the included micro-USB cable, requires no drivers on Windows (plug-and-play), and is lightweight with a compact plastic housing for increased portability.

How to use
Connect the hub to your DisplayPort source using the DisplayPort input on the adapter, then attach up to three DisplayPort monitors to the adapter's DP outputs. Connect the included micro-USB cable to provide bus power if required by your configuration. On Windows systems that support MST, the device will function as plug-and-play—no additional drivers are needed. Configure display mode (mirror, extend, or independent outputs) through Windows Display Settings to arrange monitors and set resolutions and refresh rates appropriate to your setup.
Usage recommendations
To achieve the maximum single-monitor resolution (8K @ 30Hz) both the source graphics output and the connected monitor must support DisplayPort 1.4. For multi-monitor setups, choose lower resolutions or refresh rates per the supported combinations (for example, 4K @ 30Hz or 1080p @ 60Hz across three displays) to ensure stable performance.
