Looking at the spec on Newegg:
http://www.newegg.com/Product/Product.a ... 6814125413Looks like 1 DVI, 1 HDMI and 2 mDP.
Since the Benq W1080ST is HDMI input we're going to need to adapt the DVI and one of hte mini-displayport to HDMI so we can have all three ports out on one card pushing HDMI signal to the projectors.
The DVI to HDMI is pretty straight forward. You can use a DVI-HDMI adapter.

http://www.monoprice.com/Product?c_id=1 ... 1&format=2Once you have one card feeding all three W1080ST via 1 DVI, 1 HDMI and 1 DP with the proper adapters, you can go into the AMD Catalyst Control Center and setup the Eyefinity 3x1 span. Once enabled, both Nthusim Plus and your simulator will see it as one display span. From there, just configure the Nthusim grid and save the preferences, then minimize Nthusim to the taskbar.
One thing to be mindful of, Nthusim 4.0 will be released in the next few weeks. It adds desktop pre-warping so the Windows desktop will also be properly configured. 4.0 should read the 3.4 preference file just fine. All you need to do to enable 4.0 desktop is go into the Tools menu and enable the DWM checkbox.
