+      <para>One or more monitor sections specify the charateristics of your
+      monitor(s).  Usually, the setup program can probe your monitor and setup
+      a monitor properly, however, this does not always work.  The most common
+      entries that need to be updated are <option>HorizSync</option> and
+      <option>VertRefresh</option>.  If the configuration program does not set
+      these properly, you will notice a resolution much lower than desired.
+      The default <option>HorizSync</option> setting is 28-33kHz which is very
+      conservative.  The default  <option>VertRefresh</option> is 43-72Hz.
+      Consult your monitor documentation or search on line for the proper
+      settings for your monitor.</para>
+
+      <para>It is also possible to control many detailed timing characteristics
+      of a monitor with a <option>Modeline</option> setting.  Most users will
+      not need to do this, but details are in the man page referenced above.
+      </para>
+
+      <warning><para>Incorrect monitor settings can destroy your monitor or
+      even set it on fire!  For most newer monitors, the result of overly
+      aggressive settings is a blank screen, but older monitors do not all have
