Locate KoH.in2 in "C:\Users\%your pc name%\Appdata\Roaming\Black Sea Studio\Knights of Honor\" (Appdata may be hidden), or try to search for it.
Open it with notepad and edit:

fullscreen = 1
mode = xx <- mode from listdisplaymodes e.g. "63"
width = xxxx <- should be "1920"
height = xxxx <- should be "1080"
freq = xx <- should be "60"
