I don't know what you mean by "exactly", but on a 72 DPI display any given image will be exactly 4 times the size (twice as tall and twice as wide, width times height) of that exact same image on a 144 DPI display if rendered at its native pixel size. ---- No, it won't. If you display an 800x600 pixel image on ANY screen it will take up EXACTLY 800x600 pixels. The fact that one screen is 800x600 and the other is 1280x1024 means nothing. It may appear larger or smaller because of the different monitor resolutions but it's not. It will always be 800x600 pixels. We are talking about displays here. While it's a number that you can calculate DPI/PPI mean nothing to a monitor. They are measured in total pixels. My screen is 1920x1200 and 24". Does that mean that a 22" monitor at 1920x1200 is a better monitor? No. It has the same number of pixels in a smaller amount of space: smaller pixels. Both can only display 1920x1200 pixels at a time. DPI is really only applicable when talking about the print medium where it really means something.
