DPI vs screen size??

[Just Me]

From programming I know that most thing in Windows are specified by the
number of pixels. Like a large icon is 32x32 pixels.

How come, increasing the DPI in ControlPanel/Display makes things bigger.
Seems to me they should get smaller. For example, 32 dot take less room
with 120 DPI than with 96 DPI.

Can anyone clarify this for me?

That is for the benefit of things defined in inches (eg size of the
Display dialog itself) or points (eg fonts) and is saying 'use more dots
for each inch' - hence looks bigger
For things defined actually *in* pixels, like Icons, use the facilities
on the appearance page, clicking Advanced

dpi = dots per inch, used mostly in connection with printing and
scanning.

For video display one dot = 1 pixel, unless the application program is
configured to resize images to fit the screen.

My 17 inch monitor is currently set to display 1024 x 768
The visible display area measures 12.1/2 x 9 3/8 (approx) inches.

This means that my display is showing the equivalent of 82 dpi.

Hope this explains the situation.
