B156-004-V2 Datasheet, PDF (1/3 Pages) Tripp Lite. All Rights Reserved – 4-Port DisplayPort 1.2 Multi-Stream Transport (MST) Hub, 3840 x 2160 (4K x 2K) UHD

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 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 of your graphics card. If
the total percentage of bandwidth taken up by all the connected monitors exceeds 100%, an image will not
display on one or more of them.
4-Port DisplayPort 1.2 Multi-Stream Transport (MST)
Hub, 3840 x 2160 (4K x 2K) UHD
MODEL NUMBER: B156-004-V2
Description
The B156-004-V2 4-Port DisplayPort 1.2 MST Hub connects up to four DisplayPort monitors to the DisplayPort
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 into one large monitor in video wall mode.
The B156-004-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, this hub supports expanded video resolutions, such as 3840 x 2160 (4K
x 2K) 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 DisplayPort source. LEDs indicate when the monitors are receiving a signal. The B156-004-V2 complies with
the Federal Trade Agreements Act (TAA) for GSA Schedule purchases.
