HP Notebook PCs - Display Types and Adjusting Notebook Display Settings in Windows XP

Overview of display resolution

Resolution is the number of pixels (individual points of color) contained on a notebook display, expressed in terms of the number of pixels on the horizontal axis and the number on the vertical axis. The sharpness of the image on a display depends on the resolution and the size of the screen. The same pixel resolution will be sharper on a smaller screen and gradually lose sharpness on larger screens because the same number of pixels are being spread out over a larger area.

The following table provides the maximum resolution available for each standard display type.
