Product information

Description

The StarTech.com MSTMDP123HD Multi Monitor Adapter connects up to three HDMI displays to a single Mini DisplayPort (mDP) 1.2 output. It enables multi-monitor setups on Windows devices that support DisplayPort 1.2, and functions as a video splitter on earlier DP revisions. The compact, black plastic adapter supports high-resolution output for both extended and mirrored desktop configurations and is powered from a 100–240V supply.

Advantages

This MST hub lets you drive three independent HDMI monitors from one mDP 1.2 port, improving multitasking and productivity by extending your desktop or mirroring content. It leverages the host video card to deliver high-definition output while minimizing system resource use. The adapter supports Ultra HD 4K (3840 x 2160 at 30Hz) and full HD 1080p resolutions, is lightweight (0.12 kg) and compact for easy integration into portable workstation setups, and includes a 3-year manufacturer warranty with lifetime technical support.

How to use

Usage recommendations

For best results use on Windows systems with native DisplayPort 1.2 support to enable independent displays. When targeting 4K output, verify that connected monitors and HDMI cables support 4K@30Hz and check GPU capability to drive multiple high-resolution screens.
