... whatever I set my resolution at determines how many pixels are displayed on the monitor, if it were 1500 x whatever then I'd have 1500 pixels across the width. Divide that by the number of inches (15) and I'd have a resolution of 100 ppi :-)...
In addition the fact that screens can be set at a wide variety of resolutions, the inherent dpi of a screen, which is not important other than fonts, can be anywhere from 72 to around 120. Some of the TabletPC products that were around a few years ago had native resolutions of 122. However, what screens display are pixels, not inches, so the constant use of 72dpi is a waste of energy. An image that is 640x480 will display the same whether the dpi are set at 1 or 1 million.
