----- Original Message ----- From: <PhotoRoy6@xxxxxxx> : I thought all monitors were 72dpi except Apples/Macs which are 96 dpi? no that's an old myth.. lets assume that I have a monitor that's 15" across the bottom width and is set at 1600 x 1200 or 1280x1024 or 1024 x 768 or 800 x 600 or 600 x 480 the first resolution is 106ppi the second, 85ppi the third is 68ppi fourth is 53ppi the last is 40ppi <yuck!> 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 :-) and from memory it was the macs that were traditionally set to 72 ppi and the PC's which were usually set at 96 ppi .. karl (screen width of 2304 pixels, with a potential of 2880 :-)
