Display Devices
There are two types of display devices you should be familiar with: notebook screens and external monitors.
Notebook screens are typically LCD and are measured by the diagonal length of the screen. Screen sizes range from several inches to 17” widescreen on most commonplace laptops. Screen resolutions vary, but that is much less of a concern now than it has been in the past.
External Monitors
CRT Monitors
For years, Cathode Ray Tube (CRT) monitors were standard and very few people could afford an LCD screen like a laptop uses. Over the past several years, LCD has become the predominant type of external monitor – it’s hard to even find a CRT monitor (though I have a couple in the basement you can have!).
CRT monitors are known for their size and bulk, but have great picture and color quality. It took several years for LCD to catch up – and exceed – CRT monitors. CRT monitors range in size from old 12” to 24” and larger.
LCD Monitors
Over the last several years, LCD monitors have become very commonplace and are loved by consumers for their small size and low weight. At one time LCD monitors were very pricey as compared to CRT monitors, but the price gap has narrowed so much as to not be a significant factor any longer.
You must be more careful with an LCD monitor as it is easier to damage than a CRT monitor.
