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