Hello!

I just bought History Line, but I can't get it to work in the correct aspect ratio. It is always distorted to fill my 1920x1080 monitor. I tried to edit the file "dosboxBI1HL.conf" but it had no visible effect. I also used the GOG DOSBox Configurator to set my resolution and checked "Keep Aspect Ratio" without any success.

Can anyone help me?

Thanks in advance
Michael

Thank you for the hint.
The nvidia scaling options were good, but I also have an intel onboard graphic chip.
I had to add 640x400 (or 320x200) to user defined resolutions in the Intel-HD-Graphics-Tool.

Also, I had to run "Launch Graphic Mode Setup" as an administrator. Otherwise saving the settings had no effect.

edit: I can not mark my own answer as the solution, so I will just mark yours. :-)
