Where To Buy


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.

Thanks for sharing your review of our SP123DP DisplayPort spanner. We are very sorry for any confusion regarding what this product can do. This product is designed to let you use two monitors as if they were one large screen. To the operating system, there would be just one large display. While this is great for some people, many prefer independent displays; where different applications can be viewed on each display. We would recommend using another product like our DisplayPort Multi-Stream Transport (MST) hubs to achieve independent, extended displays. Please check with your computer manufacturer or graphics card manufacturer to ensure it supports MST hubs. Here is a link to the MST hub we would suggest:

Hello Pollo, Thank you for taking the time to review our SP123DP DisplayPort spanner. We are sorry to hear about the issues when used with the Radeon R9-280 and we would like to offer some help. Are you able to provide any detail on specific issues you have seen? Were any DisplayPort video adapters being used with this product? With the Radeon R9-280 we would recommend using another product that would take advantage of the card’s support for DisplayPort MST. This would allow each display to be detected independently by the computer system and would also be a more cost effective solution. If your model of R9-280 uses Mini DisplayPort we would recommend our MSTMDP123DP which is a Mini DisplayPort to 3 port DisplayPort adapter. If the card uses a full sized DisplayPort connection, our MSTDP123DP would be recommended. Here are links to both products: Mini DisplayPort version: DisplayPort version: We are always here to help with our free lifetime technical support. If this did not resolve your issue, please get in touch with us and reference case #332-286977 so we can further assist you. You can also reply here and we will be sure to follow up. Thank You, Customer Support
