The B155-003-DP-V2 3-Port Mini DisplayPort 1.2 to DisplayPort MST Hub 4K connects up to three DisplayPort monitors to the Mini 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 three monitors, extend the desktop across them, or combine all three as one large monitor in video wall mode. The B155-003-DP-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 Ultra High Definition (UHD) video resolutions up to 3840 x 2160 (4K x 2K) at 24/30 Hz. In video wall mode, it supports expanded resolutions, such as 5760 x 1080 in a horizontal 1 x 3 monitor configuration or 1920 x 3240 in a vertical 3 x 1 configuration. This Multi-Stream Transport (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 Mini DisplayPort source. LEDs indicate when the monitors are receiving a signal. The B155-003-DP-V2 complies with the Federal Trade Agreements Act (TAA) for GSA Schedule purchases.
