StarTech Triple Head DisplayPort Multi Monitor Adapter


The SP123DP Triple Head DisplayPort® Multi Monitor Graphics Expansion Module/Adapter is an external multi-monitor spanner/splitter that lets you add multiple displays (up to three) to a desktop or laptop PC, from a single DisplayPort source.

This versatile graphics expansion module enables you to combine 3 DisplayPort monitors as a single display, for a panoramic multi-display setup at resolutions up to 3840x1024 - all without opening the computer case. The expansion module also lets you clone (mirror) your primary display, using the device as a 3-port DisplayPort splitter.

Compatible with a DisplayPort video card and displays, the graphics expansion module requires no software installation for multi-display applications, simplifying configuration and saving time.

The SP123DP is backed by a 2-year warranty and free lifetime technical support.
