Windows 10 Not Recognizing Multiple Monitors

Installed Windows 10 x64 Technical Preview 9926 on MacBook Pro Retina Display, running OSX 10.9.5.  I have 2 external monitors connected via DVI mini display port adapters.

Essentially, Windows 10 is only recognizing a single Monitor.  Device Manager only shows a single Generic Non PnP Monitor.  A Windows 8.1 x64 VM on the same machine recognizes both monitors, and Device Manager shows 2 Generic Non PnP Monitors.

I've tried changing the VM General Parameters to using Windows 8 x64 instead of Windows 10, with no change.  I've tried editing the VMX file to include the following settings with no change.

svga.autodetect = "FALSE"

svga.numDisplays = "3"

svga.vramSize = "134217728"

svga.maxWidth = "8192"

svga.maxHeight = "4096"

Any one else running into this issue? 

Thanks in advance!
