Computer with DisplayPort 1.2-compatible graphics card (e.g. AMD Radeon with AMD Eyefinity) required for video wall mode. Backward compatible with most DisplayPort 1.1a equipment running current graphics drivers with feature set limited to that of your equipment. Compatibility with older graphics cards not guaranteed. MST compliant DisplayPort 1.2 graphics cards are limited to a bandwidth of 21.6 Gbps amongst all monitors, with higher resolution monitors using up more bandwidth. 1080p monitors will use up approximately 22% of bandwidth, whereas 4K monitors will use 40% or more. As each monitor will be different, it is necessary to verify the percentage of bandwidth being used by each monitor in the display settings interface for your graphics card. If the total percentage of bandwidth taken up by all of the connected monitors exceeds 100%, an image will not display on one or more of them.Maximum supported video resolutions and number of monitors depend on your graphics card. Check graphics card specifications to determine its capabilities.

Overview

The B155-004-HD-V2 4-Port Mini DisplayPort 1.2 to HDMI MST Hub connects up to four HDMI monitors to the Mini DisplayPort (MDP) output on your computer. Ideal for digital signage in schools, churches, conference rooms, trade shows, hotels and retail outlets, this hub allows you to display the same image on all four monitors, extend the desktop across them, or combine all four as one large monitor in video wall mode.

The B155-004-HD-V2 is compliant with DisplayPort 1.2 and backward compatible with versions 1.1 and 1.1a with the feature set being limited to that of your equipment. It supports high-definition video resolutions up to 1920 x 1080 (1080p) per monitor. In video wall mode, it supports expanded resolutions, such as 4K @ 60 Hz (3840 x 2160) in a 2 x 2 monitor configuration or 7680 x 1080 in a vertical 4 x 1 configuration.

This MST hub also supports HDCP, EDID, DDC and 48-bit Deep Color (16 bits per channel), as well as DTS-HD, Dolby TrueHD and 7.1-channel surround sound audio. It works with all operating systems. Plug-and-play convenience means no software or drivers are needed. A built-in six-inch cable connects directly to a MDP source. LEDs indicate when the monitors are receiving a signal. The B155-004-HD-V2 complies with the Federal Trade Agreements Act (TAA) for GSA Schedule purchases.

Questions & Answers

What is DisplayPort?

DisplayPort is a high-performance digital interface for transmitting audio and video signals. It was developed to replace older technologies, such as VGA and DVI, and has become one of the most advanced display technologies.

What is MST or multi-stream transport?

Multi-Stream Transport (MST) allows multiple monitors to be connected over a single DisplayPort or Mini DisplayPort connection. To use MST, you need monitors that support DisplayPort 1.2 daisy chaining or a DisplayPort MST Hub (also referred to as an MST splitter or DisplayPort splitter). For a full explanation of MST, see DisplayPort Multi-Stream Transport (MST) Explained.
