The SP123DP2DVI Adaptor

From their website:

The SP123DP2DVI Triple Head DisplayPort to DVI Multi Monitor Adapter is an innovative, external multi-display adapter that allows you to add multiple displays (up to three) to your desktop or laptop from a single DisplayPort source.

The SP123DP2DVI Expansion Module lets you combine three DVI monitors as one display, at a maximum resolution of 3840×1024, to make the ultimate wide screen desktop. The Expansion Module can also clone your primary display and function as a 3 Port DisplayPort to DVI Video Splitter.

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

Backed by a 1-year warranty and free lifetime technical support.


  • Easy to use and works with any operating system
  • Expand your desktop or clone primary display
  • Supports resolutions up to 3840×1024 when connected to three displays
  • External adapter allows use with desktops or notebooks
  • Supports connection to HDMI monitors using DVI to HDMI adapters (sold separately)
  • Supports connection to Mini DisplayPort sources with adapter (see accessories) for use with DVI Displays


  • Increase the maximum resolution that you can output from your video card; add and combine up to three displays at a maximum resolution of 3840×1024
  • Use as a video wall for digital signage applications requiring wide screen or panoramic displays
  • Clone your primary display and use the SP123DP2DVI as a three port DisplayPort video splitter
  • Run multiple applications on separate monitors – edit images, video, audio clips across three displays


A Close Look

The device has three DVI connectors on one side, labelled 1, 2 and 3. When you use them you must use them in order, so if you only have 2 monitors, you would use port 1 and 2.
