Question Why is resolution important?
Answer Resolution measures the number of pixels used to form an image on the computer screen. The higher the numbers, the better the resolution. For example, resolution of 1280 x 1024 means there are 1280 pixels in each horizontal row and 1024 pixels in each vertical column.At higher resolutions, the refresh rate of a screen slows down; on a smaller screen, high resolutions may place added strain on your eyes. For these reasons you may not want to use the highest screen resolution that a CRT monitor supports. Instead, use a resolution that is high enough to show sharp detail but low enough to allow for a quicker refresh rate and less flickering.
Question What are refresh rates?}
Answer A monitor's refresh rate, measured in hertz (Hz), tells you how often the monitor redraws or refreshes the screen per second. The rate, which depends on the computer's resolution, decreases as the resolution increases. The higher the refresh rate, the less flickering on the screen and strain on your eyes.
Question Why is dot pitch important?}
Answer The picture on your monitor is made up of lots of tiny dots of the same color. The dot pitch is the distance between dots that make up the image on your CRT. The smaller the distance between dots, the better the image.
Question What are flat-panel monitors?}
Answer Also called LCD (liquid crystal display), these monitors are more expensive but show a higher-quality image, use less energy than CRTs and produce little to no flicker. They are ideal for small work areas.
Question What are the best uses for aperture-grille and shadow-mask CRT monitors?}
Answer Within the CRT category, there are two major types of tube monitors: aperture grille and shadow mask. Aperture-grille monitors consist of stripes rather than dots on the screen face and display brighter colors. Although the more common shadow-mask monitors do not offer the vivid colors of an aperture grille, they show a finer text image and are less expensive. Shadow-mask CRTs are suited for word processing and spreadsheets; aperture-grille CRTs are great for the graphics professional.
Question What about natural flat CRTs?}
Answer They have a flat glass face that produces less glare and distortion.
Question What size monitor is right for me?}
Answer This is an important decision because your monitor's size and quality affect how much you will enjoy using your computer. Think about how you plan to use the computer and the size of your workspace.Monitors are measured diagonally along the surface of the cathode ray tube (CRT). A 17" monitor contains a tube that is 17" diagonally across the screen. Because a plastic case surrounds the tube, the viewable image is less than the stated monitor size.A bigger monitor produces larger images, more detail and less eyestrain. If you use your computer for extended periods, you'll be happier with a larger monitor. A smaller monitor is adequate for basic computer needs such as word processing and e-mail.The following criteria may help you choose a monitor:
15"
Low cost
Ideal for first-time buyers
Good match for people who mostly do word processing or smaller spreadsheet applications
17"
Common upgrade size from a 15"
Good for Web surfing, word processing, and spreadsheets
Best balance between price and viewable image
19"
Perfect for desktop publishing, and graphic design
Popular with gamers
21"
High resolutions and refresh rates
Popular with professional graphics designers
