Appendix C. Monitor terminology

As you read the documentation that came with your monitor and the monitor information provided in this chapter, you might find a few technical terms. If you change your monitor settings, refer to the following table to understand some of the terms used to describe monitor characteristics.

Table 1: Monitor terms and definitions

Term	Definition
display mode	A resolution setting associated with a vertical frequency
	setting (and sometimes a color setting). For example, 640x480
	at 75 Hz, 256 colors.
horizontal frequency	Rate (in kilohertz [kHz]) at which each line on the screen is
	drawn.
interlaced	Method of producing an image by drawing only alternating
	lines until the entire image is completed.
noninterlaced	Method of producing an image by drawing each line, one after
	the other, until the entire image is completed. This method
	produces less flicker than the interlaced method.
pel (or pixel)	A picture element. A small rectangle or portion of an image
	that together with other pels make up the entire image.
resolution	The number of pels required to display an image horizontally
	and vertically. For example, 640x480 means 640 pels
	horizontally and 480 pels vertically.
SVGA	Super video graphics array. A video standard that provides
	some of the higher text and graphics resolutions.
vertical frequency/	Rate (in hertz [Hz]) at which the entire image is drawn on the
refresh rate	screen. Also called “refresh rate.”
