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 1920x1080 (1080p) per monitor. In video wall mode, this hub supports expanded video resolutions, such as 4K at 60Hz (3840x2160) in a 2x2 monitor configuration or 7680x1080 in a vertical 4x1 configuration. This MST hub also supports HDCP, EDID, DDC and 48-Bit Deep Color (16-Bit 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 6" cable connects directly to a DisplayPort source. LEDs indicate when the monitors are receiving a signal.
