Step 2: Find a Suitable Monitor
Buy, beg, or borrow a suitable monitor. There are three main choices: monitor type,
size, and resolution.
Choose Between LCD and CRT
You??™ll probably want to start by choosing a monitor type:
CRT (cathode ray tube) CRTs are the old-technology, TV-style monitors
that have a large tube at the back. CRTs are inexpensive but bulky, almost all
use an analog signal, and give a less sharp picture than LCDs. Apart from
price, CRTs??™ only advantage is being able to show a good picture at various
different resolutions. For example, you may need to set a lower resolution to
run some software (such as children??™s educational programs).
LCD (liquid crystal display) LCDs are the newer, flatter monitors. LCDs
are more expensive than CRTs, but prices have now fallen far enough for
LCDs to be of better value than CRTs. LCDs come in three types: analog,
digital, or capable of both. Digital LCDs give the best picture. Apart from
price, LCDs??™ main disadvantage is that they normally can show only one
resolution (the native resolution) crisply; you can use other resolutions, but
the picture becomes ???blocky??? and jagged.
