You are faced with a great many options when
choosing a monitor for your computer. Used monitors come in many forms, ranging
from used, to seller refurbished, manufacturer refurbished and third part
refurbishment and de-branding. There are also two major monitor models in the
market, CRT or LCD.
CRT also known as cathode-ray tube, the technology used in most televisions and
computer display screens. A CRT works by moving an electron beam back and forth
across the back of the screen. Each time the beam makes a pass across the
screen, it lights up phosphor dots on the inside of the glass tube, thereby
illuminating the active portions of the screen. By drawing many such lines from
the top to the bottom of the screen, it creates an entire screen full of images.
LCD or liquid crystal display, a type of display used in digital watches, many
portable computers and computer display screens.
LCD displays utilize two sheets of polarizing material with a liquid crystal
solution between them. An electric current passed through the liquid causes the
crystals to align so that light cannot pass through them. Each crystal,
therefore, is like a shutter, either allowing light to pass through or blocking
the light.
Does Size Really Matter?
The primary real world difference between these
monitors is their size. CRTs take up significantly more desktop space then does
their much thinner LCD counterparts. CRT monitors can often be found at highly
aggressive pricing; often times a 21" CRT can be purchased for less than 1/4 the
price of the equivalent LCD. CRTs can be more expensive to ship, generally
produce more heat than an LCD monitor and require more desktop space. Being that
CRTs have been in the market for many years, they are often very reliable and
cheaper to repair than LCDs.
Why are some monitors cheaper than others?
Regarding monitor conditions and quality, a used
monitor is just that, used, perhaps cleaned before resale. Any existing defects
including screen burns, scratches, dents, and bruising are left unprepared.
These monitors can often be found in excellent condition and often at a very
aggressive price but generally do not come with a manufacturer warranty.
A reseller refurbished monitor is returned to as close to possible new condition
by the reseller. The pricing of these units are usually aggressive and generally
come with a reseller warranty.
Factory refurbished monitors are returned to new condition by the original
manufacturer and often come with a full factory warranty. Factory refurbished
monitors are generally priced higher than used or reseller refurbished
equipment, but their higher pricing does not always guarantee a higher quality
product.
A factory refurbished and de-branded monitor is a monitor that has been returned
to like new condition by a third party factory. Often times these factories have
agreements with the original manufacturer that require them to de-brand this
equipment, in other words, to remove the original manufacturers name from the
unit. These units will range in price but are often of very high quality.
