PC Monitor Displays:
We were using and recommending
19" CRT Flat Panel Analogue Monitors. Some our of PC Builders have
opted for LCD Flat Panel Monitors where space & heat are of a major
concern. LCD prices are now more affordable!
For CRT - We currently use AOCMonitors.com
available from AxionTech.com whom
we work with regarding our Special Build Sessions.
For LCD - We recommend
CRT Specs To Look For:
CRT (Analogue - Cathode Ray
Tube) Flat Display or LCD (Digital
- Liquid Crystal Display) Flat Panel Display.
All monitors today 15" and above
will also be able to 'over scan'. 'Over scanning' is the ability to
stretch the display size beyond the normal rectangular viewing
This way you will not see that black
band of nothing around the display perimeter. This feature is set
either through the Monitors' On Screen Display Controls or through you
Video Card Display software Drivers or both.
Matching a Monitor Display to the
proper Display Adapter (Video Card) is essential for maximizing your
Display output potential. If the Display Adapter is of a higher
quality than the Monitor Display and correspondingly set for a higher
screen resolution than a Monitor Display is capable of handling then
you may either see a distorted view or nothing @ all. Windows is
extremely difficult to maneuver without a visual Display even with
screen readers for the Visually impaired.
Larger is better! 19" is
perfect for most Users and priced right!
- Refresh Rate: 72
Hz (Hertz) or greater. A higher Refresh Rate number is
better here! The refresh rate is the number of times per second the
image is painted onto the screen. The default Windows refresh
frequency setting is 60 Hertz, although your monitor may support a
high setting. Hertz are
the frequency of electrical vibrations (cycles) per second.
Check your manufacturer's documentation for information regarding
the settings your Monitor supports. When using a Presentation
Projector, it's important to know this value or else you may not
be able to synch video signal from what you see on the Desktop with
what Users should see on the Projector Screen. When all else fails -
Experience & a Good Technician counts!
The higher the refresh rate, the less
"flicker" noticed. Flicker is a fluctuating image on a video
screen. A higher refresh frequency reduces any flicker on your Desktop
screen, but choosing a setting that is too high for your
Monitor can make your Desktop Display
unusable and cause damage to your hardware and will have you seeking
Windows Safe Mode!
Remember, Refresh Rate = How
often the video screen is retraced in order to prevent the image from
flickering. The entire image area of most Monitors is refreshed
approximately 60 times per second by default.
- Resolution: Get a higher
resolution than you'll use. Screen Resolution is expressed as a
matrix of dots. The number of horizontal dots multiplied by the number
of vertical dots (pixels). Resolution = the density of the screen
image. Expressed as 640 horizontal
pixels x 480 vertical
This setting determines the amount of information appearing on your
screen, measured in dots or pixels. Low resolution, such as 640 x 480,
makes items on the screen appear large, although the screen area is
small. High resolution, such as 1024 x 768, makes the overall screen
area large, although individual items appear small. Monitor and
Display Adapter together determine your ability to change Screen
Resolution & Color Bit Depth Depth.

- 800x600 - Windows XP Default (Lowest
Microsoft Windows Media - Choosing the Right PC for Windows Media
High Definition Playback
On a 19" Monitor you'll view it ideally @
1024x768. A 19" monitor should be
capable of 1600 x 1200 Maximum Resolution @ 75Hz Maximum Refresh Rate.
This is good! A 19" Monitor should be able to display a lower
resolution (example of 1280x1024) @ a higher refresh rate (100Hz) Non-interlaced.
This is desirable and easier on eye strain. You do NOT want a Monitor
with an interlaced Display! An interlaced Display with a low refresh
rate will give Users a headache quickly. Whereas a Non-interlaced,
high refresh rate Monitor will give many hours of comfortable viewing
enjoyment during work or play!
- Color Bit Depth: More colors & higher resolution require
a Video Adapter with more Memory. Today, we routinely Spec a Video
Card with 64 MB's RAM.
- Standard VGA - 16 Colors
- Super VGA - 256 Colors
- High Color (16 bit)
- High Color (24 bit)
- True Color (32 bit)

- The Two Main Types of CRT Technologies... The Mask - Invar
Shadow Mask & Slot Mask or Aperture
Grill Slot Mask... Comparing Apples
- Shadow Mask -
A thin screen full of holes that adheres to the back of a color
CRT's viewing glass. The electron beam is aimed through the holes
in the mask onto the phosphor dots. There are generally more holes
per inch than the maximum resolution obtainable from that Monitor.
The distance between these holes is called the dot pitch.
- Slot Mask -
A type of shadow mask used in CRTs. It refers to two different
- The first is the Aperture Grille used in Sony's
Trinitron monitors, which uses vertical phosphor
stripes and vertical slots in the mask compared to the
traditional shadow mask that uses phosphor dots and round
holes in the mask.
The aperture grill model is held together by two thin wires
called "damper wires" and can frequently be visible
across screen and image.
- The second is a combination of traditional Shadow Mask
& Aperture Grille technologies used in NEC's
CromaClear monitors. Sometimes known as a slotted
shadow mask, this mask uses elliptical holes and vertical
- Dot Pitch & Slot Pitch
Dot Pitch -
The distance between a RGB dot and the closest corresponding RGB dot
on a Color Monitor - Typically from .21, .25, .28 to .31mm. The
smaller the Dot Pitch, the crisper the image. A .28 dot pitch means
dots are 28/100ths of a millimeter apart. A smaller dot pitch provides
a sharper image, especially desirable on text.
Shadow mask accuracy is measured using diagonal, horizontal, and
vertical dot pitches.
Slot Pitch -
The distance between like-colored phosphor stripes in a CRT that uses
a Slot Mask. This is slightly closer than the Dot Pitch in traditional
Shadow Mask CRTs, which measures the diagonal distance between dots.
Aperture grille accuracy is measured using Slot Pitch.
- Price - All of the above for what you're willing to pay for it as
opposed to what a Manufacturer asks for it! Supply & Demand.
The Monitor brand you choose will determine the Mask technology used by
the Monitor Manufacturer. As with any PC
Component, choose the Monitor best suited your applications' point of

- Sony's 'Hi-Bright' CRT technology; FD Trinitron different from other
- The difference between Trinitron Technology
and Shadow Mask Technology?
"A shadow mask is a metal plate with
holes through which electron gun passes beams of electrons to
generate the pixels on the screen. This lets less light through
and is more subject to distortion than an aperture grille. The
Trinitron aperture grille allows a greater number of more
precisely aligned electron beams to reach the screen than the
older, traditional shadow mask system. The result is a clearer,
better focused and far brighter image."
