StarTech MSTMDP122DP Dual DP Multi-Monitor Adapter
Overview
The StarTech MSTMDP122DP is an active adapter designed to drive two independent DisplayPort monitors from a single Mini DisplayPort 1.2 output. This is critical for users needing expanded desktop real estate for productivity applications, data analysis, or complex security monitoring interfaces where multiple high-resolution displays are essential. Its active conversion ensures compatibility with graphics cards that require a DisplayPort signal, unlike passive adapters. The MSTMDP122DP is powered via USB, simplifying installation by eliminating the need for an external power adapter.
Compatibility
This adapter is compatible with any system featuring a Mini DisplayPort 1.2 output. It supports dual monitor configurations up to 3840x2160 (4K) resolution at 30Hz on each display. It is suitable for use with laptops, workstations, and mini PCs that require expanded display capabilities for applications such as VMS clients, NVR interfaces, or workstation management software.
Installation Notes
The adapter requires a USB port for power, drawing 5V DC. The maximum recommended cable distance from the source to the adapter is 6.6 ft. The adapter itself has a cable length of 7.5 inches, and the total product length is 15.2 inches. Operating temperature range is 0°C to 40°C (32°F to 104°F).
