ME: LAUGHING ALL OVER

I say it again and again (see my previous posts):

I cannot overemphasise the previous advice. To better illustrate this point, see
the next table. I see my monitor easily beats your "110 DPI LCD"! ;-)

MONITORS DPI
*APPARENT* resolution of different size CRT monitor screens
Screen Size   | 14 inch  15 inch  17 inch  19 inch  21 inch

 640 x  480   |  66 dpi   60 dpi   51 dpi   44 dpi   40 dpi

The explanation is just wonderful, and I am too lazy to explain it myself, so
please read this excerpt:

> The numbers 72 and 96 dpi do sort of exist (in their imaginary way)
> in computer operating systems. This existence does seriously confuse
> people who imagine these numbers might be about showing images, but
> these numbers never affect any image in any way. These numbers are
> only used to compute Text Size on the screen. The reason is because
> text font size in Points is dimensioned in inches (designed for paper),
> but screens are only dimensioned in pixels. The definition of a Point is
> 1/72 inch - there are 72 points per real inch on paper. A 12 Point font
> is 12/72 inch height printed on paper (inches exist on paper, and paper
> is dimensioned in inches, and fonts are dimensioned in inches).
...
> But not to worry, the operating system simply dreams up and uses some
> fake 72 and 96 dpi numbers to compute text size on the screen.
