DPI selection

What should I use? 96dpi or my native which is 109dpi?

For what?

Fonts on a monitor.

>>91
96 dpi
DPIs would be awesome if developers (me included) actually cared, but since everything is written with pixels in mind (and admittedly, some things just ought to), you might not like how things look if you change it.

Most people have 85 DPI and still set it to 96 DPI which is the default.
