Ever since I started using computers, I have, like almost everyone else, used CRT monitors. I started out with a fourteen-inch monitor and have gradually moved over the years to my current nineteen-inch model.
CRT monitors have changed quite a bit since I bought my first one. Resolutions have increased tremendously, and so has the color depth that is supported. CRT monitors have also gone from having adjustment knobs under the monitor to being completely digital, requiring only the push of a single button to change many different options. Best of all, the prices for CRT monitors have dropped over the years. Now you can purchase a seventeen-inch monitor for about two hundred dollars.
CRT monitors may have been around for a while, but they aren’t without their hazards. Did you know that CRT monitors hold a dangerous electrical charge even after they’re turned off? The charge can actually last up to several years and be hazardous and even deadly to anyone who opens a CRT monitor casing. Then there is the additional danger of radiation. Did you know that a metal shield behind the glass of your monitor protects your body from a flood of radiation? CRT monitors have also been known to cause fires due to electrical malfunctions and excessive heat if the ventilation holes are accidentally covered up.

LCD monitors offer an alternative to CRT
LCD is the new kid on the block in the monitor game, and it has gained the attention of many computer enthusiasts. While LCD monitors have been used on laptops for many years, only now have these devices become popular enough for vendors to mass-produce them for the desktop PC market.
Like the CRT monitor, the LCD monitor has undergone many changes since its introduction. The first LCD laptop monitors were very small due to manufacturing costs. The quality of these monitors wasn’t exactly great either, due to the small number of transistors available in the LCD display technology.
Initially, LCD monitors used a passive matrix display, which consisted of two transistors charging the intersecting axes of an x/y grid to control pixel color. However, the onset of the active matrix display has greatly benefited LCD monitors. Active matrix displays contain a transistor for each pixel, and this produces a greater quality image due to the increased amount of transistors. Most LCD monitors now have active matrix displays.
Most people who have seen an LCD monitor have also probably seen the price tag that comes with it. These monitors don’t come cheap. Cost is currently one of the major drawbacks of LCD monitors. As the technology continues to improve and manufacturers continue to mass-produce these monitors, however, expect the prices to drop over the next few years.
Another drawback to LCD monitors is the plug interface that is needed to connect to the computer. Some LCD monitors require a special digital plug-in interface in order to work with the monitor. The problem is that this plug is not available on most computers, so another video card or adapter must be purchased to plug these LCD monitors into the computer.
