It's still easy to get swept away with unnecessary bells and whistles. A larger screen means less eyestrain, less scrolling and easier navigating through text-heavy Web pages. If your desk surface just can't accommodate that kind of girth, LCDs are generally between 7 and 9 inches deep and weigh in at a trim 12 or 13 pounds. Most LCD screens are 14 to 18 inches, but what they lack in size compared to the CRTs, they make up for in clarity. This is one of the main factors in determining picture quality.
Resolution refers to the number of pixels or screen dots.
Obviously, more pixels mean higher resolution. But you can reach a point of diminishing returns here because as the number of pixels increases their size decreases along with everything else on the screen. Only CRT monitors refresh. In selecting a CRT monitor, many of the leading makers recommend that you don't go below 75 Hz, or you may be able to detect a slight flicker if you have sensitive eyes. What's more, with prices as low as they are, there's no reason to settle for less.
