Communicate with your computer system. Quite simply, without a monitor, you've got nothing. Bear in mind, however, that certain types and sizes of monitors may let you do more than others, depending on your needs.

Large-screen monitors display larger images or, when combined with a computer having high-resolution capabilities, allow you to see more without scrolling -- a necessity for serious desktop publishing.

Multiscan monitors, when used with a compatible computer, allow you to change resolutions with a click of your mouse.

Monitors that are capable of displaying high resolution and millions of colors ensure that full-blown graphics will appear in all their glory. When complex images are displayed on monitors or computers that have lesser color capability, they may appear blurry, even if the images' resolution is high.

Larger monitors with higher resolution and better color capability cost more than less-capable monitors. Always buy the best image you can afford. Your eyes will thank you.
