You may have already noticed that your monitor can be set to different screen resolutions and to display different numbers of colors. We recommend that you use monitor settings of 800 X 600 pixels with thousands of colors for viewing web pages.
Most people think of resolution in terms of photographs or television.
In those media, resolution indicates picture sharpness. In the computer world however, screen resolution refers to the dimensions of the pixels displayed on a screen. Your computer may have come pre-set to a resolution of 640 X 480 pixels. The size of the monitor does not determine the screen resolution. But the bigger the monitor, the larger the screen resolution you can use.
