Quality
The quality of a monitor is measured in two ways. The dot pitch is
a measurement of the sharpness of the monitor. The dot pitch is generally
a fraction of a millimeter and is the shortest distance between two dots
of the same color. Generally, most monitors dot pitch is below .28mm. A
common rule of thumb, the lower the dot pitch the sharper the picture,
hence the better the quality.
The second quality measurement is the refresh rate. The refresh rate
is a rating of the frequency the monitor "refreshes" the image on the screen.
Since the chemical reaction only lasts for a few milliseconds, the monitor
must refresh multiple times per second. The more the monitor refreshes
the less the user experiences the "flickering effect". The refresh rate
is measure in Hertz (Hz), and a monitor will normally have a refresh rate
of about 60Hz or more.
