The traditional type of color
display screen that has been used for years in televisions. In reality, all
monitors based on
CRT technology (that is, all monitors except
flat-panel displays) are analog. Some monitors, however, are called
digital monitors because they accept
digital signals from the
video adapter.
EGA monitors, for example, must be digital because the EGA
standard specifies digital signals. Digital monitors must nevertheless translate the signals into an analog form before displaying images. Some monitors can accept both digital and analog signals. Some analog monitors are also called digital because they support digital controls for adjusting the display.
Most analog monitors are multifrequency monitors, which means that they are designed to accept signals at two or more preset frequency levels.
