I have an external monitor connected to my laptop.
My laptop has display settings | scale and layout set to 150%.
My external display settings | scale and layout set to 100%.
In Scrivener I have set GUI font, binder font and other display fonts to a comfortable size for my laptop (the defaults).
When I move Scrivener to my external monitor, I seems to automatically reduce the fonts from 150% to 100%. The fonts are then tiny. Other programs don’t seem to do this.
