placing your display in such a way that the side faces the window or any light
source
•
•
•
•
•
minimizing room light by using drapes, shades or blinds
using a task light
changing the display’s viewing angle
using a glare-reduction filter
using a display visor, such as a piece of cardboard extended from the display’s top
front edge
•
•
Avoid adjusting your display to an awkward viewing angle.
Avoid looking at bright light sources, such as open windows, for extended periods of
time.
Developing good work habits
Develop the following work habits to make your computer use more relaxing and
productive:

To make installation easier, so long as your system supports the DDC protocol, the
monitor is able to plug-and-play. The DDC is a communication protocol through which
the monitor automatically informs the host system about its capabilities; for example,
supported resolutions and corresponding timing. The monitor supports the DDC2B
standard.
