Vertical Refresh Rate
The vertical refresh rate
of your CRT is important.
If it is too low and/or
you’re using fluorescent
lighting, the screen will
appear to flicker. To re-
duce flickering on a CRT,
use faster refresh rates
(we recommend a refresh
rate of 72Hz or more). But
first check your monitor’s
documentation to make
sure it can support the
rates listed by the video
driver. The default refresh
rate for VGA monitors
(without drivers) is 60Hz.
