INTRODUCTION
Purchasing a computer monitor can be one of the most
important pieces of the computer as it is what will
display everything coming from your computer.
TECHNOLOGY
Before looking at what type of configurations you
need to look for when purchasing a computer monitor
it is important to know if you want a CRT or a Flat
Panel / LCD monitor.
CRT
- Today one of the most commonly used technologies
for computer monitors. CRT or Cathode Ray Tube is
a technology much like what you will find on most
TV’s.
CRT monitors are an affordable solution however is
bulky and very heavy.
Flat
Panel / LCD -LCD or Liquid Crystal Display
monitors are similar to what is found on portable
computers. LCD monitors overall generally display
much sharper of an image, are lighter and more space
efficient however are much more of an expensive solution
for desktop displays.
SIZE
When
considering purchasing a monitor utilizing the CRT
technology it is important to consider the following:
Dimensional
Size - Size can be one of the more important
considerations when purchasing a computer monitor.
Monitors are available in 15",17", 19"
and 21". Like most things, larger is generally
more expensive. However the larger the screen the
more amount of viewable space you will be able to
work with. We generally recommend users that plan
on utilizing there computer for more then one-two
hours a day and have the available space purchase
at least a 17" monitor. Users who plan on using
the computer for graphic art or cad we highly recommend
utilize at least a 21" monitor. Finally users
with little space or plan on using the computer for
word processing / e-mail may want to consider a 15"
monitor.
Viewable
Size - The viewable size of the monitor is
a very important consideration and can vary by manufacture.
The viewable size is the size of the viewable area
and not the complete monitor.
DOT
/ STRIPE PITCH
When
purchasing a monitor Dot Pitch or Stripe Pitch is
a very important consideration. Dot Pitch measurement
is found on most monitors and 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. We recommend that when
purchasing a monitor the Dot Pitch be no bigger then
0.25
Stripe Pitch is a measurement used
with Trinitron or Diamondtron monitors and is a measurement
(in millimeters) that separates two like-colored stripes.
The lower the Stripe Pitch the higher the quality
of image.
When looking at monitors you should
only see a Dot Pitch measurement or a Stripe Pitch
measurement. You should not see both of these measurements
measuring the same monitor.
Finally these two different types
of measurements should not be a measurement comparison
when deciding between two or more monitors, each technology
is different.
RESOLUTION
The
maximum resolution is the amount of pixels that can
be displayed horizontally x vertically. Be cautious
when purchasing a monitor at any size that advertises
a large resolution size such as 1,600 x 1,200 for
a 15" monitor.
Some monitor manufactures may allow
for such high resolutions at a high cost but the user
will never utilize such a resolution. As the monitor
increases in size the image display will decrease,
the following is a listing of a usable resolution
limit by the size of the monitor. These sizes can
be debated however are the standard and most easily
viewed resolutions.
15"
- 800 x 600 / 1,024 x 768
17"
- 1,280 x 1,024
19"
- 1,280 x 1024
21" - 1,600 x 1,200
REFRESH
RATE
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.
CONTROLS
When
purchasing a monitor it is important to look at the
available controls of that monitor. The controls allow
a user to modify and or adjust the viewable settings
of the display.
READY
TO BUY
Once
you have reviewed the appropriate information and
believe that you are ready to make a purchase of a
new monitor ensure that the source which you plan
on purchasing the monitor from is a reputable source
and you have reviewed our section on what to look
out for when purchasing over the Internet.
