The B155-002-DVI-V2 2-Port Mini DisplayPort 1.2 to DVI MST Hub connects two DVI 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 both monitors, extend the desktop across them, or combine both as one large monitor in video wall mode. The B155-002-DVI-V2 is compliant with Mini 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) at 60 Hz on each monitor. Expanded video resolutions are supported when displaying in video wall mode, such as 3840 x 1080 in a horizontal 1 x 2 monitor configuration or 1920 x 2160 in a vertical 2 x 1 monitor configuration. The B155-002-DVI-V2 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. This MST hub works with all operating systems. Plug-and-play convenience means no software, drivers or external power supply is needed. A built-in six-inch cable connects directly to a Mini DisplayPort source. LEDs indicate when the monitors are receiving a signal. The B155-002-DVI-V2 complies with the Federal Trade Agreements Act (TAA) for GSA Schedule purchases.
