Harry,

I've just stuck Parallels 11 on my MAcBook Pro, installed Windows 8.1 Pro on this, and loaded my Einscan software onboard. Unfortunately, I can't get it to work yet. I am able to extend displays, and sort the resolution to 800x600 using the Control Panel List All Modes route, but I can only detect displays in Parallels Vu mode, and it keeps defaulting to "Available display output on: Paralles Display adapter (WDDM)" for the second monitor/display. Just trying to sort it out now, not so sure it'll be a quick fix, but for now I can't recommend the Parallel 11 route, so just stick with BootCamp. Years ago on an early build, I pointed Parallels at a Bootcamp instal, and that did overcome a problem I had, but I've slept since then.
