I have downloaded and installed FG 2020.3.9 and it works very well.
I was wanting to use two monitors one for front view the other left side.
I have followed a 2018 FG forum post, "multi display setup, by Takapa (21 may 2021)" created mypreference.xml copied code to ....doc\ mypreference yet it doesn't work.
Front view fine and flies well left screen shows just the desk top.
running windows 10, shows both monitors, set to extend these displays.
Can someone please tell a 70 year old what he has done wrong !!!
kind regards Warwick
