SLIM FACTOR
|
LCDs are much slimmer than
their CRT counterparts. This
slimness brings along a host
of advantages such as space
saving and portability.
|
Bulky, the back size is
proportionate to the size of
the monitor
|
VIEWABLE SCREEN
|
A 15 inch LCD always has a
same size of viewable area
as the specifications say.
Larger displays may have
their viewable area reduced
by at most 0.1 inches. |
The viewable area is always
about 0.9 - 1.1 inch smaller
than the size specified on
paper. This is due to the
frame around the glass
screen So a 15" CRT would
have only about 14" of
viewable area. |
SCREEN FLATNESS
|
100% ninety degrees true
perfect flat screen
|
Many manufacturers tout true
flatness for their CRT
monitors, but the sad truth
is that most are fake. In
reality its only the outer
glass that is flat, and not
the actual screen. The true
100% perfect flat monitors
are the aperture grille
tubes made by Mitsubishi and
Sony.
Even then, these tubes
have a disadvantage - a
faint thin line or two
(Depending on size) running
through the screen to
stabilise the grill.
Some people find this
distracting, especially if
you work on a light
background (eg. documents)
most of the time. |
RADIATION
|
LCDs emit a very small
amount of radiation compared
to CRTs. Health conscious
consumers prefer them for
this one reason.
|
CRTs emit electromagnetic
radiation. Much of it is
filtered by the lead heavy
glass front and the rest
that reaches your eyes are
mostly harmless. Even
then, radiation still passes
through the screen and some
people regard them as
hazardous. |
WEIGHT
|
LCDs are very light, hence
being portable. 17 inch
LCD weighs around 6kg.
19 inch LCD weighs around
7kg. |
CRTs weigh heavier,
especially in their front
(the display area)
17 inch CRT weighs around
16kg.
19 inch CRT weighs around
20kg. |
P OWER
REQUIREMENTS
|
Considerably lower power
usage. 17 inch LCD
requires around 35 watts
19 inch LCD requires
around 45 watts |
Higher power usage, more than
200% to an LCD of equivalent
size.
17
inch CRT requires around 90
watts
19
inch CRT requires around 110
watts |
Display
Sharpness
|
Sharp (when used at native
resolution)
|
Slightly less sharp images - but
its noticeable |
Automatic
Resize
|
Hit the Auto button, and the
display resizes to fit every
pixel within its viewable
area.
|
Newer CRTs come with a Auto-Fit
feature, but unfortunately it
does not work well and requires
micro adjustments to fill the
screen |
Burn-In
|
LCDs are free from the
burn-in issue that plagues
CRTs and Plasma displays.
However, they do
occasionally have Image
Persistence problems which
can be fixed by switching
off the LCD for an extended
period of time. |
Suffers from burn-in problem. If
displaying a same image for a
prolonged period, it could be
embedded in the display
permanently. |
Refresh Rate
|
LCDs do not "paint" their
image. They provide a
flicker free image every
time.
|
A
minimum of 75hz is required for
a flicker free image. |
Warmness
|
Little
|
Back gets noticeably warm after
some time, thus making the room
temperature warmer. |
|
GLARE |
Little or no glare |
Glare
is reduced by the use of special
filters and treated glass. |
