A monitor may or may not be included with
the computer system you purchase.
If one is included, it will typically be a
smaller 15" or 17" monitor of low quality.
You may need to purchase a separate monitor
after you've selected your computer system.
The most important factors involved in
picking a monitor include:
Monitor Type, Size and Viewable Area
Maximum Resolution Settings
Monitor Refresh Rate
Dot Pitch (or stripe pitch)
Recommendations: 17" monitor minimum (16"
viewable size), 75 Hz or higher refresh
rate, 0.26 mm dot pitch or less, and capable
of at least a 800x600 resolution.
Monitor Types and Sizes
There are two main styles of monitors: the
standard CRT (like a small television) or a
Flat Panel / LCD monitor (shown in the image
above).
CRT Monitors - One of the most
commonly used technologies for computer
monitors, CRT (Cathode Ray Tube) is a
technology much like what you will find on
most TV's. CRT monitors are affordable, but
they are rather bulky and heavy.
Flat Panel / LCD - LCD or Liquid
Crystal Display monitors are similar to what
is found on portable computers. LCD monitors
generally display much sharper of an image,
and they are both lighter and more space
efficient. However, they are much more
expensive than CRT.
Monitors also come in various sizes, which
are generally 15", 17", 19" and 21".
Beyond the actual overall physical size of
the monitor, you need to check out it's
viewable size. The viewable size (measured
diagonally) is the exact size of the
monitor's viewable glass screen and not the
complete monitor.
This is important because it determines how
much area you will actually view when using
the monitor.
Dot Pitch (or Stripe Pitch)
A monitor's dot pitch is a measurement that
defines the amount of space (in millimeters)
that separates two adjacent pixels that are
the same color. The smaller the dot pitch
the sharper the image, For example, a 0.25
mm dot pitch monitor provides a sharper
image than a 0.27 mm.
Similar to dot pitch, stripe pitch is a
measurement used specifically with Trinitron
or Diamondtron monitors and is a measurement
(in millimeters) that separates two
like-colored stripes.
Like dot pitch, the lower the stripe pitch
the higher the display quality of the
monitor.
Monitor Resolution
The resolution of a monitor is the amount of
pixels that it can display horizontally and
vertically. For example, 800 x 600 means the
display will be 800 pixels wide and 600
pixels high. Standard monitor display is 72
pixels per inch.
The following is a listing of suggested
resolution limits based upon monitor size.
15" Monitors - Best at 640x480 or 800x600
17" Monitors - Best at 800x600 or 1024x76
19" Monitors and up - Best at 1024x768 or
1280x1024
The refresh rate is a measurement of the
number of times per second the screen is
redrawn. This measurement is measured in
hertz and it is recommended that a monitor
have at least a refresh rate of 75 MHz at
the resolution you wish to run at.
LCD or Flat Panel display monitors will
generally cost more than standard CRT
monitors. Also, the larger a monitor is, the
more it will cost. When shopping for a
