Is it possible to tell forge not to use the second monitor?

[DSDV]

Hello,

my system has a second small monitor which just displays a little monitoring software which is set as floating exception for forge.
so far so good and everything works great.

but every so often ( i did not yet figure out what/when it is casued) forge uses this second screen to display a program there when its opened.
so i would love an option to tell forge gjust to use my main monitor or to ignore the second one (:

does anyone know a way to do so?

with kind regards
