SETMON(1G)							    SETMON(1G)

NAME
       setmon - a monitor configuration tool

SYNOPSIS
       setmon [<options>] [devicefile]

DESCRIPTION
       setmon is used to inquire and modify the video timing mode for a speci‐
       fied graphics device.  When changing the monitor mode, users may select
       from  among  a  list  of	 available monitor modes.  The monitor mode is
       described by its display resolution, refresh rate  (Hz),	 and  a	 brief
       description.

       On  systems where multiple graphics displays are configured for use the
       devicefile is used to identify the  graphics  device.   The  devicefile
       will  default to "/dev/gvid" for OEM graphics devices or "/dev/crt" for
       HP Visualize graphics devices.  Users may want to use the sam interface
       (pre  HP-UX 11.31 release) or the smh interface (HP-UX 11.31 and later)
       to identify the mapping between graphics devices and device files.   In
       sam/smh	go to the "Display" -> "X Server Configuration" panel, and use
       the "Actions" -> "Describe Screen" menu item.

       Invoking setmon without the -s or -r options will cause an  interactive
       session	to be invoked. In the interactive session, a list of potential
       monitor modes will be displayed and the user will be allowed to	select
       one  to	apply.	 The  user  will be asked to confirm his choice before
       restarting the X server.

       When a monitor mode is selected, it is recorded to be  used  each  time
       the  X  server  is  started  up.	  For OEM graphics devices the mode is
       recorded in the /etc/X11/XF86Config file.  For  HP  Visualize  graphics
       devices the mode will be written into the system stable storage.

       OEM  graphics devices will use the Extended Display Identification Data
       (EDID [TM]) along with the Display Data Channel (DDC [TM]) interface if
       it  is  supported  by your monitor.  This mechanism is used to identify
       the timings and video modes that your monitor supports.	 The  list  of
       available monitor modes may change as a result of this.

       If  EDID/DDC  is	 not available, setmon will offer a list of predefined
       default modes.  Not all of these may  be	 supported  by	your  monitor.
       Choosing an unsupported mode may result in a bad or no visible image on
       your monitor.  Consult your monitor manual for supported video modes.

OPTIONS
       setmon recognizes the following options:

       -p      Print out the detailed timing information for  the  current  or
	       selected monitor mode.

       -r      Report the current monitor setting and all available choices.

       -s index
	       Sets monitor mode to index.  This option bypasses the confirma‐
	       tion dialog and installs the specified video mode.

       -v      Verbose, print extra information.

       For OEM graphics cards, the following options are also available:

       -C num  Return information about a specific connector on	 the  graphics
	       card.

       -M      Return  the  monitor  information for the device specified.  -M
	       will cause other options to be ignored.

       -N      Return only the name of the device specified.   -N  will	 cause
	       other options to be ignored.

       For  HP Visualize graphics cards, the following options are also avail‐
       able:

       -t      This option makes the new monitor  mode	temporary.   A	system
	       reboot will restore the previous monitor mode.

EXAMPLES
       These  examples	assume	that  "/dev/gvid"  points  to a valid graphics
       device.

       To invoke an interactive session type:
	   setmon /dev/gvid

       To change the current monitor mode to entry three type:
	   setmon -s3 /dev/gvid

       To report the current monitor setting type:
	   setmon -r /dev/gvid

       Here is the "setmon -r" output  (assuming  /dev/gvid  maps  to  an  ATI
       Radeon 7500 device):

       The ATI Radeon 7500 QW graphics device connector 2 supports the follow‐
       ing monitor entries.

	  Entry Width Height   Hz Derivation and Recommended Usage
	  ----- ----- ------  --- --------------------------------
	     1	 1024	 768   60 DDC defined, Flat Panel
	     2	 1024	 768   70 DDC defined
	     3	 1024	 768   75 DDC defined
	     4	 1152	 864   75 DDC defined
	 ->  5	 1280	1024   60 DDC defined, Flat Panel
	     6	 1280	1024   75 DDC defined

	 The current monitor selection is entry 5.

       The "->" marker identifies the current monitor selection.  The  deriva‐
       tion  column  indicates	that  these  timings vere obtained via the DDC
       interface from your monitor and are thus supported by your monitor.

WARNING
       On HP Visualize devices this command fails if  the  device  is  locked.
       This  will  occur when the CDE login screen is visible and the user has
       not logged in.
