B/W Monitor and Color Monitor

In the past, 9 to 12 inch (diagonal) B/W monitors were widely used in the field. These days, many people are looking for 14 inches for color monitor and 17 inches for B/W. As the color monitor needs 3 different color dots to produce one pixel of information on the monitor, it usually has lower resolution than B/W monitor.
