Technology

• Flat panel monitors use LCD technology and can handle either digital or analog video signals. CRT monitors use cathode ray tubes and analog video signals.
  
  

Weight

• Flat panel monitors weigh a fraction of what a comparable sized CRT monitor weighs. A single person can carry a 22-inch flat panel while it frequently took two people to carry a 21-inch CRT monitor.
  
  

Space

• Large CRT monitors take up large amounts of space on a desk while flat panel monitors take up very little.
  
  

Placement

• Many flat panel monitors have mounting holes on the back panel so they can be attached to a wall mount. CRT monitors were placed on the corners of desks or in the corner of a cubicle in order to minimize space.
  
  

Power Consumption

• CRT monitors use much more power than flat panel monitors. According to a cnet.com test, a 20-inch CRT monitor had a 63 percent greater cost to run than a 21-inch flat panel monitor.
