The whole world is changing to LCD monitors – and for good reason! The display is a fundamental part of any computer system and these screens have huge benefits over CRT monitors:

Virtually zero radiation
Low power consumption of around 25w (1w in standby)
Low consumption means a monitor can pay for itself within 3 years
Improved image quality
Improved desk space
Improved health & safety
Zero flicker

Screen Size
LCD monitors are typically sized by their actual viewable diagonal measurement, but CRT monitors are measured from the outer edge of the tube! For example, the viewable area on a 17" LCD monitor will typically measure 17" diagonally, but the viewable area on a CRT monitor will typically only measure 16" diagonally.

Image Resolution
The quality of the image on the monitor is measured in pixels (picture elements) and the higher the pixellation the better the image quality. Resolution ratings are categorised as follows:

VGA 640 x 480 pixels
SVGA 800 x 600 pixels
XGA 1024 x 768 pixels
SXGA 1280 x 1024 pixels
UXGA 1600 x 1200 pixels
