This USB-C to DisplayPort MST Hub enables a connection to three DisplayPort monitors, using a DisplayPort Alternate Mode (DP Alt Mode) capable USB-C enabled host device. IT Pro Performance
This adapter features a unique video signal booster which amplifies the signal and ensures reliable performance, even with lower quality cables. The amplifier also increases the max. supported DP cable length compared to other brands.
Multi-tasking Made Easy
This USB-C to DisplayPort video splitter allows you to configure your displays in extended or duplicated mode. Connecting three independent 4K 60Hz displays creates high-performance workstations. This empowers increased multi-tasking across your organization, resulting in increased productivity.
4K at 60Hz and HDR
Multi-Stream Transport (MST) technology combines multiple video signals into a single output signal/stream. This MST Hub separates the single input stream into three independent signals, one for each DisplayPort enabled display. Support for High Dynamic Range (HDR) offers increased contrast, brightness, colors, and greater luminosity.
Hassle-Free Setup
Windows devices that support DP Alt Mode over USB-C feature native support for MST. This USB-C to DisplayPort hub is compatible with Thunderbolt 3/4, and USB4 enabled Windows devices. Plug-and-play installation, with no drivers or software required. The 12in (30cm) attached cable provides options for flexible installation configurations, reducing the amount of strain on ports and connectors. Additionally, this triple-monitor splitter is bus-powered, meaning no external power is required.
This product is backed for 3-years, including free lifetime 24/5 multi-lingual technical assistance.
