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 with LCD s should reduce complaints of eyestrain.

Space and Energy

Because LCDs are smaller than CRT, LCDs required little space than CRT monitor. LCD also require lesser energy than CRT Monitors.
