I’m attempting to set up 3 monitors as well, having been able to get FP to work, but still don’t understand how exactly to edit he registry to offset the physical monitor real estate. The backglass monitor is a 22” display set at native 1260x768; and the DMD display a 19” at the same resolution. I've tried modifying various windows10 registry settings (graphics display y coordinates and communication “00” and “01”) with no effect.
Can someone explain how to “stretch” the Backglass to display on to the DMD display, and/or how and where to change the registry.
thanks
