Your first concern should be size of
viewing area. The more area there is the easier it is
to read text and see graphics. Generally if a flat panel is advertised
as a fifteen inch than that will also be the total viewing area.
A fifteen inch flat panel screens is equivalent to a 15 inch
viewing area. A fifteen inch FPS is equivalent to a CRT 17 inch
monitor. The seventeen inch FPS is equivalent to a CRT 19 inch
monitor. A noticeable difference with these screens are their
size and weight. Normally their depth is no more than four inches.
There will be a support of some kind to support the screen to
a base. Most FPS are designed to sit on a flat surface such as
a desk but a fold up base will allow it also to be mounted to
a wall. The screen and assemble take up little space and weigh
half as less of a CRT.
Pixels and resolution. One pixel
is made up of a tiny cell which contains a thin layer of liquid
crystal quarts (LCD). This quarts is stimulated by electricity
to produce light. The light is what produces the one resolution
of the screen. There are no options for setting the screen to
different resolutions. What you see is what you will always see
on that monitor every time it is turned on. Panel less than fifteen
inches tend to have limited resolution and clarity.
Pixels per inch or the quality that
you want your image and text to be. This is also understood
as picture resolution and is measured by a series of pixel on your monitor screen. Panels are
made up of many pixels which work
together to form an image or the text that you can see.
When you are presented with number like these:1024 x 768 this
is pixel resolution. The more pixels the sharper your images
and text will be on the screen, however this will add considerably
to the total cost of the monitor.
How bright is bright enough?
This is an important consideration. Screens are back lite which
provide the illumination. The measurement is one unit of light
this unit is called nits. Most panel screens have between 150
to 200 nits. More is better. The FPS uses a light which
is rated for hours of life. A panel rated for 50,000 hours will
give you many years of good service. The best test is to open
up a word program and start typing. Check the text and view images
for cleanness.
Hertz is not a big consideration.
Flat panel screens are considered to be flicker
free. In there design and the way they work flicker is less likely
to cause any eye strain or fatigue. If hertz are included with
specifications they are relating to the electrical out let that
it will be getting its power from. People prone to having seizures
are less likely to have one.
Next you may want to consider positioning.
A flat monitor will cause less glare . Have a limited viewing
angel of about 100 degrees, and should be viewed straight on.
As you move off center the images will become distorted and washed
out
FPS adjustment controls and what to
look for. Most of to days panels have on screen controls
or are digital. What this means is there are four physical buttons
somewhere on the front of the panel. One button is for mode,
another button is sub mode and the two buttons left are for changing
value either up / high or down / low. So here is what you get:
auto image adjustment | contrast | brightness | Horizontal size
| Vertical size | Horizontal position | Vertical position | fine
tune | sharpness, | color adjustment - 9300k, 6500k, and default
5400k | setup menu ( panel information like serial number, resolution
back ground color and time out) | memory | recall | and languages.
Each manufacture has added a few more or a few less than what
is here. In large these control allow you to adjust almost everything
there is relating to the FPS/LCD that you are looking at.
Emissions are important to you cause
radiation generally causes cancer and this is not something you
want. The majority of panels are certified as low emissions
which meet or exceed standards set by the Swedish. These panels
must also have a MPRII certificate rating sticker on them or
the newer certificate rating to look for is the TCO.
Power saving mode. Many panels
come with software even though they are plug and play ready to
go as soon as they are attached to your computer. This software
detects when little or no power is required for it. When this
happens for a period normally set by the user the unit will turn
itself off or goes into a sleep or powdered down mode. This is
to conserve energy and also will help increase the life of the
light source. Did you know that the average
life span of a FPS / LCD is about five years.
Conversion or VGA Many of the
panels are imputed for an analog signal. So you can hook them
up to a computer that may have once used a VGA CRT monitor. Some
come with a converter such as Apples latest FPS/LCD screens.
Ask before buying if you will need a converter for your type
of purchase to your computer.
There will always be extras provided
by the manufacture. You can buy them with built in speakers,
or microphone or jacks for one. Jacks for external head phones
or more speakers. Some allow for hooking extra USB. If you really
needed this extra stuff than go for it, but generally I am looking
just for a flat panel screen and that is it. You can buy that
extra stuff if you need it later.
Making the connection is important too.
Something else you won't want to forget when make the final
purchase is will it be used for a PC or Macintosh computer. The
connectors are different on both machines and you may need an
adapter. Or the power saving software may not work on your operating
platform. You want to know these things before bring this thirty
or fifty pound monitor home.
