
Monitor displays use liquid crystal display (LCD) or cathode ray tube (CRT)
technology

Resolution is also a factor when it comes to monitors. It’s the number of
individual dots of color, known as pixels, contained on a display.

Resolution is expressed by identifying the number of pixels on the horizontal
axis (rows) and the number on the vertical axis (columns), such as 800x600.

Resolution is affected by a number of factors, including the size of the screen.


Two measures describe the size of your display: the aspect ratio and
the screen size

computer displays, like most televisions, have had an aspect ratio of
4:3. This means that the ratio of the width of the display screen to the
height is 4 to 3.

For widescreen LCD monitors, the aspect ratio is 16:9

Screen sizes are normally measured in inches from one corner to the
corner diagonally across from it



Most CRT monitors require the signal
information in analog form
The computer and video adapter convert
digital data into analog format.
Once the display information is in analog form,
it’s sent to the monitor through a VGA cable.
DVI keeps data in digital form from the computer
to the monitor.
 LCD monitors work in a digital mode and support
the DVI format
 The DVI specification is based on Transition
Minimized Differential Signaling (TMDS) and
provides a high-speed digital interface.
 DVI cables can be a single link cable that uses one
TMDS transmitter or a dual link cable with two
transmitters.

Liquid crystal display technology works
by blocking light
 LCD is made of two pieces of polarized
glass that contain a liquid crystal
material between them.

Video Cards receive binary data from
the CPU and turn it into pictures you can
see
 The CPU and Software Applications send
info to the Video Card, which then sends
the information to the monitor.

Large amount of memory space
 Fast Processor
 Frame Rate- amount of images
displayed per
second
 Triangles per second

Must be compatible with the buses on
motherboard
 If the motherboard has onboard video,
disable the onboard video in the BIOS
when installing a card in the bus slot
