If your display is using a resolution not listed above, it's very easy to compute the values you need for DisplaySize. Use "DisplaySize x y" where

x = (horizontal resolution)*0.254

and

y = (vertical resolution)*0.254

both rounded to the nearest integer. Again, the physical display's aspect ratio should be considered for non-square pixels.


For 1024x768, this would be

x=1024*0.254, or x=260

and

y=768*0.254, or y=195

so you would use "DisplaySize 260 195".
