The default is to use 75 dpi fonts, so

1024 pixels 	
-----------  =	13.6533 inches = 13.6533 * 25.4 mm = 346.7946 mm
75 dots / in 

768 pixels @ 75dpi = 260.096 mm

Or if you have a more precise screen you man be using the 100dpi fonts: 
1024x768 @ 100dpi = 260.604 x 195.072 mm

Your DisplaySize line starts with "#", so probably isn't actually being 
used.
