Interface Challenges - Font size

I have a somewhat urgent issue with the interface font. I have to work remote and most of my applications are behaving when I have mixed monitor sizes open. Toad Datapoint unfortunately has microscopic font in the navigation, table, properties pane and toolbars. Open to any suggestions as I have to use a magnifier to see anything. Again this is 1 of say 15 apps. I'm using windows 10

Solved. The larger monitor must be made the primary monitor so that Toad starts and adjusts fonts to that monitor.
