To keep prices down, some computer makers include a cheap monitor with a dot pitch of .39 mm or more. Avoid these systems or ask if you can pay a few dollars more for a better display. The higher the refresh rate, the less the screen will flicker. Larger monitors increase the amount of information you can view at one time. This is visually appealing, but the monitor still needs to support a high enough resolution and small enough dot pitch to retain sharpness and clarity in the display area.
Larger monitors tend to be much more expensive than their smaller counterparts.
But a 17-inch screen can make a remarkable difference in your computing experience. If you have to choose one place to spend a little more money, this is it. Some monitors packaged with systems from major manufacturers come equipped with speakers, microphones, headphone jacks and audio inputs. If you want a different monitor, you may have to buy some of these items separately.
