This document provides an overview of various display technologies used in monitors, including cathode ray tubes (CRT), light-emitting diodes (LED), liquid crystal displays (LCD), and gas discharge tubes. It explains how these technologies create images on screens and discusses the measurement of monitor resolution in terms of pixels both horizontally and vertically, as well as the importance of resolution in displaying detailed images. Additionally, it draws parallels between laser printers and other imaging technologies such as televisions and copy machines.

LCD display devices • use a large tube full of electrons to make the image • use Light emitting diodes to form the image • use Liquid crystals to form the image • use a tube full of gas to make the image
A monitor’s resolution • is measured in pixels across and pixels down • is measured in microseconds • is a measure of the detail that can be shown • A and C
A laser printer uses the same technology as • a CRT • a television • a copy machine • none of the answers
