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.
