Connects three DisplayPort monitors to one DisplayPort 1.2 output at up to 3840x2160 @30Hz with mirror, extend and video wall modes
- Connect three DisplayPort monitors from one DisplayPort 1.2 output using MST technology
- Achieve 3840x2160 resolution at 30Hz on each connected display for Ultra HD clarity
- Choose mirror, extend or panoramic video wall modes to suit different workflows
- Power the hub reliably via the included USB 3.0 cable — USB 2.0 does not supply enough power
- Integrated 7.9" DisplayPort cable and 3.3 ft USB power cable keep the setup tidy
Three-Port MST Hub for DisplayPort 1.2
This DisplayPort 1.2 MST hub splits one output into three DisplayPort connections. It targets desktop or laptop users who need multiple monitors from a single port. Mac systems are not supported. A GPU capable of driving more than three external screens is required. The hub draws power from a USB 3.0 port.
Bandwidth allocation across three screens
Total bandwidth is 21.6 Gbps. At 3840x2160 resolution the refresh rate is limited to 30 Hz and consumes 40 percent of bandwidth. Lower resolutions such as 2560x1600 or 2560x1440 reach 60 Hz using 38 and 35 percent respectively. 1920x1200 and 1920x1080 at 60 Hz use 30 and 22 percent.
DisplayPort 1.2 interface limits
The hub complies with DisplayPort 1.2a and cannot exceed its 21.6 Gbps ceiling. Three 4K streams at 30 Hz fit within that ceiling but higher refresh rates at 4K are impossible. Mirror mode with NVIDIA Surround is restricted to two displays. Video Wall mode needs AMD Eyefinity, Intel, or NVIDIA Surround graphics.

Questions about this item
Does the hub generate noticeable heat or fan noise when driving three 4K monitors all day?
The hub has no fan and draws power from a USB 3.0 port, so it runs silently with minimal heat during extended use.
What ports and GPU capability must my computer already have for this hub to work?
You need a DisplayPort 1.2 output and a USB 3.0 port for power; the GPU must support more than three external displays.
Will this hub work with my older monitors that only run 1920x1080 at 60 Hz?
Yes, each 1080p 60 Hz stream uses about 22 % of the 21.6 Gbps bandwidth, leaving plenty of headroom for three displays.
