I'm trying to set full screen resolution of 800 x 640 by editing openttd.cfg. The game starts in windowed mode and I get error when trying switch to fullscreen. I've standard 19" LCD with native resolution of 1280 x 1024 , that has w/h ratio of 1.25. Playing with 1280 x 1024 res is not healthy for my eyes as everything is so small. I can set fullscreen with 800 x 600 but screen is out of proportion ( h/w ratio 1.33 ) Is there any trick that could help me to keep that "magic" 1.25 ratio ?

regards
Coco
