.... TYPES OF MONITORS ....
PC monitors come in two different flavors, each of which is known by a popular TLA (three-letter acronym): LCD and CRT.
LCD: Stands for liquid crystal display. The newer, flatter type of computer screen.
CRT: Stands for cathode ray tube. The traditional, glass-screen, television-set-like monitor.
Between the two, the LCD monitor is more popular. The prices on LCD monitors have dropped dramatically in recent years, not to mention that the monitors are easy on the eyes and use less electricity than their glass-based counterparts.
.....FEATURES OF MONITORS. ..
CRT
CRT monitors are cathode ray tube, similar to CRT televisions. These televisions use red, green and blue electrons flowing from left to right, filling each line on the display. When these electrons hit the phosphor on the CRT, they glow for a short time. They need to be refreshed; video cards with too low a refresh rate will cause flickering of the screen. CRTs are prone to other types of problems such as images being burnt onto the screen, which is what the aptly named "screensaver" prevents.
LCD
A liquid crystal displays or LCD is a type of flat panel monitor, meaning it's designed to be thin. This feature should not be confused with flat screen, meaning the computer monitor's screen is flat instead of curved. LCDs refresh their screen differently than CRT monitors. An LCD screen is created by electric voltages hitting liquid crystal cells, allowing 64 different shades per cell. LCDs have one resolution size, and, if a smaller resolution is adopted, a black border will appear around the re-sized resolution.
