What are the differences between LCD and CRT Monitors

Image Distortion
                LCDs are free from geometric image distortions at the screen edges because they
are a flat matrix display where every pixel is active.
CRT s are subject to peripheral distortion of the image as the electron beam becomes
progressively more tangential to the monitor screen phosphors at the edges,
hence CRT screens typically have a black dead space around them.

Image Flicker
                LCD s are free from flicker because they do not rely on a scanning electron beam.
CRTs are more prone to flicker.

Specular Glare Problems
                LCDs have uniform screen brightness and the screen is covered with a flexible
surface that is substantially less prone to specular glare compared to a glass
covered CRT screen. LCDs are flicker free, which should reduce the risks of headaches, and the reductions in occulomotor effort (number of fixations) and the reductions in specular glare problems withLCD s should reduce complaints of eyestrain.
Space and Energy
Because LCDs are smaller than CRTLCDs required little space than CRT monitor. LCD also require lesser energy than CRT Monitors.
