LCD monitors guideA couple of years ago LCD monitors were definitely not worth the
money. These days the price difference between flat panel LCD monitors
and CRTs has decreased dramatically to the point where LCD monitors are only
about twice the price! However even though LCD monitors are more expensive to buy they
save you money because they use much less power. Another good advantage that LCD
monitors have over CRT monitors is that they are much easier to read text on, if
you do a lot of reading on your computer (rather than graphics work) then an LCD
is a good choice for you. They also save space and are great because you have
much more room on your desk for your keyboard or mouse. You see a 19" CRT
monitor takes up a lot of space and it only gives you about the same viewable
area as a 17" LCD.
Factors to consider when buying an LCD monitor LCD monitors do not resize resolutions very well. They have a
native resolution which you cannot exceed and that provides the best picture
quality. You can run resolutions lower than the native resolution but the image
will look a little blurry.
There are also two other important specifications: response time
and contrast levels. The response time is the average time required for a liquid
crystal cell to go from active to inactive and back to active again. Roughly
speaking, it refers to the time needed for a pixel to change from black to white
and black again. The time is expressed in milliseconds, and the longer it takes,
the slower the monitor's reaction. There is a direct link with image output, as
well. For example, a 20-ms monitor will display 1/0.020: 50 dark then light
images per second, or a total of 100 images per second. The contrast level is the ratio between an image's brightest and
dark points. The higher it is, the better the monitor will reproduce in-between
shades. In practice, this level gives the number of grays the monitor can
display. A high quality monitor will have a contrast ratio of 500:1 but
that is more than the average web surfer will need. If you plan on playing games then the monitors response time
will be of most interest to you. LCD monitors have a noticeable afterglow that
cause bluring when there is a lot of movement on the screen. If you play a lot of games I don't really recommend you buy an
LCD monitor. |
