Monitor Buying Guide
CRT (Cathode-Ray Tube)
A CRT works by moving an electron beam back and forth across the back of the screen. Each time the beam makes a pass across the screen, it lights up phosphor dots on the inside of the glass tube, thereby illuminating the active portions of the screen. By drawing many such lines from the top to the bottom of the screen, it creates screen image.
CRTs provide some of the best images on the market today at extremely reasonable prices. CRTs are long lasting, reliable, and a great value. The only downsides to these are that they are bulkier than LCDs and consume much more energy.
LCD (Liquid-Crystal Display)
LCD monitors use fluorescent backlights, color filters, and groups of liquid crystals to form the onscreen image. When an electrical signal is sent to the screen, the crystals react by either filtering out or projecting light onscreen.
LCDs offer incredible image quality in a package a fraction of the size of CRTs. Most LCDs feature extremely thin profiles, making them perfect for small offices and tight working environments. Unfortunately, LCD do suffer from limited viewing angles and are still relatively expensive.
Similar to LCDs, plasma monitors feature clusters of pixel cells that react to variable voltages. Each pixel cell is made up of three sub-pixels in red, green, and blue that, when energized, begin to glow.
Plasma monitors project rich, crisp images comparable to LCDs, without the limited viewing angles and the susceptibility to ambient light. They usually feature a number of various connection options, making them perfect for multimedia and conference displays. Unfortunately, Plasma screens are still relatively new to the market and very expensive.
