I need help buying dual monitors?

So I want to set up some sort of extended monitor system, I saw this picture https://sites.google.com/site/tfitts/Computer1612.jpg and I thought it looked awesome, I just cant find those half sized monitor thingies anywhere. but  have an ASUS VH236H. ah well now I guess my question is how do you do that? I am using an nvidia 550 ti.

ASUS VH236H is good motherboard, you can extend monitor using your nvidia 550TI as it has two DVI outputs and one HDMI outputs but you need to check with the vendor that it does supports the three monitor systems or not. I used to my system checked with my graphic card, it has a option like multi GPU support and multi monitor support.

Even we have that support in my point of view it does uses for Gaming only. If you are a Hardcore gamer you can try this type of system. Your Graphic card must have the capability to support multiple monitors. There are some types of devices available in the market
