AST MONOCHROME VGA MONITORS
|
|
|
|
|
|
PROBLEM: When using the AST Monochrome VGA monitor near fluorescent
|
|
lighting, the display may flicker slightly, especially when
|
|
turning on fluorescent lights.
|
|
|
|
CAUSE: The flicker is caused by the frequency difference between the
|
|
fluorescent light (60Hz) and the scanning frequency of the
|
|
monitor (50Hz).
|
|
|
|
AFFECTED
|
|
SYSTEMS: AST Monochrome VGA monitors.
|
|
|
|
|
|
SOLUTION: It is recommended that any fluorescent lighting, such as that
|
|
found in modular workstations, be located at least 20" or more
|
|
from the rear of the monitor to prevent flickering.
