LCD Monitors easily win in
this area, offering brightness approximately twice
that as CRT monitors on average. This is
particularly important for viewing in daytime,
high light areas, like a room with many windows.
LCD VGA, video monitors will easily appear
brighter than CRT monitors. An LCD manufacturer
has many more component modules to deal with than
LCD VGA, video monitors have
made great strides to narrow the gap on contrast.
Contrast is important for viewing in low light
situations and ensuring that black tones appear
black (rather than muddy grays), and is most
important for gaming and movie playback. Although
CRT monitors pull of the victory, the margin of
difference is now minor, with the best LCD VGA,
video monitors matching CRT video VGA monitors for
most practical purposes.
CRT monitors still hold the
advantage in regard to color purity and quality.
LCD monitors have again made great improvements
here, and now offer bold, brilliant colors in many
cases. The best TFT LCD VGA video monitors are
very good, and the average user would be hard
pressed to note the difference for basic computing
use. For gaming or movie watching, as well as
professional-level image editing, this difference
can range from slightly to significantly
noticeable, especially in a side-by-side
An obvious advantage for TFT
LCD VGA video monitors, and one of their main
selling points. LCD monitors can weigh as little
as 1pound for the smaller portable handheld screen
sizes, and are often just 1-6 inches deep,
including the depth of the base stand. CRT
monitors by comparison can easily weight 40-50
pounds, are often over 15-inches deep, and are
very inconvenient for moving. It goes without
saying that LCD monitors help free up a tremendous
amount of desk space.
TFT LCD VGA or video monitors do not suffer from
screen burn-in. Although most CRT displays today
also avoid this issue, because of the way TFT LCD
monitors are manufactured, there is no risk of
burn-in caused by nonmoving images that are
displayed for a long period of time.
CRT video or VGA monitors do
hold the advantage versus TFT LCD monitors here as
well. However, it should be noted that TFT LCD
monitors have dramatically improved, and current
models offer a very wide viewing angle, easily
over 160 degrees, which is all that is needed in
Response time refers to the
time the screen takes to update pixel colors. This
is very important for gaming and other fast moving
images like movie playback. A slow response time
will leave a 'trailing effect' where certain
pixels seem to lag behind the action. The very
best TFT LCD video, VGA monitors now offer sub 20
millisecond response times, which makes them
generally acceptable for gaming. CRTs of course
still hold the advantage, since their response
time is not noticeable.
For those that spend a lot
of time on a computer, one of the biggest issues
leading to sore eyes and headaches is the screen
flicker caused by CRT displays. Although screen
flicker is generally not a problem for CRT
displays that offer a 85 MHz screen refresh rate,
many monitors do not, and default Windows settings
are often lower as well. LCD video, VGA monitors
clearly are the better choice here, as there is no
flicker at all as a result of the differences in
TFT LCD vide or
VGA monitors have the advantage here, and are not
affected by magnetic sources, namely speakers. As
a result, some LCD monitors even offer integrated
speakers, and do not require special shielding.
CRT monitors are affected by the magnets in
speakers, and depending on the model and closeness
of the speaker, can result in a distorted picture.
Touchscreen for TFT LCD
VGA, Video or PC monitors
Touch screen overlays
will reduce up to 25% of the monitors brightness.
Touchscreens are becoming now more popular because
of the interfacing between computers and small
handheld TFT LCD color monitors. Handheld battery
operated TFT LCD video monitors are more popular
because of new led backlit technology that is
extending the life of the LCD calf light bulbs by
a factor of up to 5 times longer lifespans. Some
portable handheld units can now work up to 100
hours with a single set of batteries.
Again, TFT LCD vs. CRT, LCD
comes out ahead. LCD monitors consume considerably
less power than CRTs. Most LCD monitors consume
between 20-50 watts of power, while CRT monitors
generally consume 50 to over 160 watts.
Touchscreen models even more current.
Dead LCD Pixels:
One disadvantage of TFT LCD
monitors is that they do include the potential of
having so-called dead pixels, i.e., pixels that
simply do not function. These pixels cannot be
repaired, and can be quite annoying if they are in
the main viewing area of the monitor, and are
especially noticeable in word processing and other
applications where the screen background is
generally white. CRT displays do not suffer from
this issue, but TFTLCD manufacturing has improved
to greatly reduce the frequency of this problem.
