Most new computers have separate, adjustable
keyboards and monitors that allow the keyboard and monitor to be positioned appropriately
for the user. This is important because depending on the tasks, the computer user may
spend a considerable amount of time viewing the monitor. There are some basic features to
be considered when choosing a monitor:
- The monitor should be adjustable for tilt. By
tilting the monitor, bright spots or washout caused by the overhead light on the monitor
screen, can be reduced. In addition, it is also recommended to tilt back the monitor
so that the top is slightly farther away from the eyes than the bottom. As we look around
our surroundings, objects in the upper part of our peripheral vision are generally farther
away than the point we are looking at, and objects in the lower part of our peripheral
vision are usually closer. As a result, our visual system has developed to perform best
when the visual plane tilts away from us at the top.
- The monitor should be adjusted for brightness
and contrast. The brightness and contrast adjustment panel is usually located in front
of the computer monitor. The brightness of the monitor should match the brightness of the
surroundings to avoid eyes strain. It is easier to read the monitor if the contrast of the
monitor is adjusted correctly. Contrast is the difference in brightness between the image
produced by the monitor and the image reflected off the monitor. In addition, it is also
preferable to view a monitor that has white or light color than a dark color background.
Working on a computer program that has black letters and white background can reduce the
difference in contrast between the screen and what is reflected off it.
- All exposed surfaces of the monitor should be finished in a
neutral color with a non-reflective matte finish to minimize bright color and glare from
the these surfaces.
