StarTech.com DisplayPort 1.2 to 3x HDMI MST Hub 4K

Brand:

The StarTech.com MSTDP123HD is an active DisplayPort 1.2 Multi-Stream Transport hub that converts one DisplayPort output into three independent HDMI display outputs. It supports up to three 1080p displays at 60Hz, or two 4K displays at 30Hz, making it a practical multi-monitor expansion solution for Windows desktops and laptops. The externally powered plastic hub also supports HDMI 7.1-channel audio and display distances up to 15.2m.

OVERVIEW

  • The MSTDP123HD is an active DisplayPort 1.2 MST hub for expanding one compatible DP output into three HDMI displays, making it useful for office workstations, control desks and professional multi-screen environments. Compatibility: Windows systems with DisplayPort 1.2 MST support; not compatible with macOS. Model comparison: Unlike simple mirrored splitters, MSTDP123HD supports independent extended displays.
