bulky and very heavy.

are lighter and more space efficient however are much
more of an expensive solution for desktop displays.

LCD / Flat Panel displays one of the most noticeable
and considerable reasons for purchasing a Flat Panel
is its size. As you will see a Flat Panel display
is generally about 1-2 foot deep.

the screen size is measured differently from a standard
monitor. Standard monitors are measured from the bottom
left of the screen to the top right of the screen,
plastics and all. However when measuring a LCD the
actual viewable area is measured.
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.
