And *nobody* is using 300 dpi on a computer display.
More typical would be about 100 dpi, though it will vary
considerably depending on the physical size of the
screen and the mode (vga, svga, xvga, etc) used.
The fact is though, the dpi numbers are virtually
meaningless, and what actually counts is the 640x480
size in pixels.
