Picking a monitor can be an exhausting task. LCD or CRT, brightness, response time, contrast ratio, resolution, and aspect ratio, every aspect needs to be considered when buying a monitor. There are 2 basic types of monitors right now. CRT (cathode rays tube) and LCD (liquid crystal display) monitors. However, (LCD) screens are the most popular and are commonly used nowadays. One great advantage of LCDs over CRT monitors is that LCD monitor is less stressing to the eyes. LCD displays utilize LCD pockets that are embedded inside the screen and also color filters to display images. Light comes into the crystal pockets that open less or more depending on the size of the image. Monitors comes in different sizes; from 15 up to 30 inches and more, and they come in widescreen versions as well. LCD screens are light and thin, perfect for those offices where there is less space available. A high resolution LCD will display edges of images and text appear smoother. If you can see each and every pixel, you're either too close to your LCD or you most definitely need a higher resolution monitor.
