Computer display monitors have come a long way since the days when all we had were small black and white screens. In the early eighties, I used a thirteen inch black and white screen that had a display pitch of about .45 millimeters (mm) between dots which was OK but never great for text (graphics were still a ways off). Those early monitors cost about $500.00 and were quite slow.
Today because costs have come down considerably, I use different monitors for
different activities. My primary monitor is a 21-inch giant that is capable of displaying 16.7 million colors at a .25 mm dot pitch.
This monster meets my needs for as I have grown older and my sight has started
to weaken, I need the large work area. This allows me to have a lot of on-screen
information available without having to constantly switch pages.
I bought this monitor several years ago and at that time its price was considerably more than my old 13-inch monitor, but it
gave me a lot more capability (rich graphics, multimedia, full-motion video, etc.).
