Thanks, all.
I will not be able to get it run on the largest of my two monitors without turning the other monitor off in Nvidia Setup Multiple Displays.
CFS3 can do that, WOFF BHH could do that, FSX can do that, But WOFF UE can't do that on my computer.
Not a big deal, it takes only a few seconds to turn off the 2nd monitor in either Windows Screen Resolution ap or Nvidia Setup Multiple Displays ap.
And then turn 2nd monitor back on for FSX or anything else in Windows such as web browsing.
