Problem solved (Windows 10). This metod works on Settlers 3 as well. Right click on S4_Main.exe (Siedler3R.exe for Settlers 3), go to "Properties". Then "Compatibility", check "Run this program as an administrator", click on "Change high DPI Settings" and check "Override high DPI scaling behavior". Game resolution will auto-scale to your desktop resolution.
