Unable to get triple monitor setup functioning - Alienware 15 r2 w/amp and titan x

I bought an Alienware 15 r2 (NVidia 970m and 4k laptop touchscreen) and Alienware Graphics Amplifier (w/Titan X installed) a few months ago and I am now trying to get my three Asus 26" 1080p LCD DisplayPort monitors to function with it.

I have connected all three to the individual DisplayPorts on the Titan X in the amplifier, but it only detects 2 + the laptops screen in Display Properties of Windows 10. I can get it to extend the desktop to one of the monitors + the laptop screen, but I get an error when trying to extend it to the third.

Looking in Device Manager I can 3 Generic PnP monitors, two connected through the Titan X and the laptop screen. In the Nvidia control panel I can see the two Asus screens. 

I have tried the latest Nvidia drivers and I have even factory reset the laptop to try it on a fresh install with no success. All 3 Asus screens will function individually, as long as I move the DisplayPort connection around on the Titan X so I know the screens are ok.

What do I need to do to get the third Asus LCD detected and get windows 10 to allow me to enable all of them?
