intel(5):
       The 830M and newer driver supports the following outputs through  RandR
       1.2:

       VGA    Analog VGA output

       LVDS   Laptop panel

       TV     Integrated TV output

       TMDS-1 First DVI SDVO output

       TMDS-2 Second DVI SDVO output

       SDVO and DVO TV outputs are not supported by the driver at this time.

       See  xorg.conf(5)  for information on associating Monitor sections with
       these outputs for configuration.

xorg.conf(5):
       With  RandR  1.2-enabled  drivers, monitor sections may be tied to spe-
       cific outputs of the video card.  Using the name of the output  defined
       by the video driver plus the identifier of a monitor section, one asso-
       ciates a monitor section with an output by  adding  an  option  to  the
       Device section in the following format:

       Option "Monitor-outputname" "monitorsection"

       (for example, Option "Monitor-VGA" "VGA monitor" for a VGA output)

       In  the absence of specific association of monitor sections to outputs,
       if a monitor section is present the server will associate  it  with  an
       output  to  preserve  compatibility for previous single-head configura-
       tions.
...
       Option "PreferredMode"  "string"
              This  optional  entry  specifies a mode to be marked as the pre-
              ferred initial mode of the monitor.  (RandR 1.2-supporting driv-
              ers only)

       Option "Position"  "x y"
              This optional entry specifies the position of the monitor within
              the X screen.  (RandR 1.2-supporting drivers only)

       Option "LeftOf"  "monitor"
              This optional entry specifies that the monitor should  be  posi-
              tioned  to  the  left  of the monitor of the given name.  (RandR
              1.2-supporting drivers only)
...
       Option "Enable"  "bool"
              This optional entry specifies  whether  the  monitor  should  be
              turned  on  at  startup.  By default, the server will attempt to
              enable all connected monitors.   (RandR  1.2-supporting  drivers
              only)

       Option "MinClock"  "frequency"
              This  optional  entry  specifies  the minimum dot clock, in kHz,
              that is supported by the monitor.

       Option "MaxClock"  "frequency"
              This optional entry specifies the maximum  dot  clock,  in  kHz,
              that is supported by the monitor.

       Option "Ignore"  "bool"
              This optional entry specifies that the monitor should be ignored
              entirely, and not reported through RandR.  This is useful if the
              hardware  reports  the  presence  of  outputs  that don't exist.
              (RandR 1.2-supporting drivers only)

       Option "Rotate"  "rotation"
              This optional entry specifies the initial rotation of the  given
              monitor.   Valid  values  for  rotation  are  "normal",  "left",
              "right", and "inverted".  (RandR 1.2-supporting drivers only)

If any of this is inaccurate or poorly worded, patches are welcome.
