SETMON(1G) SETMON(1G)
NAME
setmon - set the current and default video output format
SYNOPSIS
/usr/gfx/setmon [ options ] format
DESCRIPTION
setmon changes the video output format to the one specified; it also
specifies the default video format to be used at system power-up or
graphics initialization. setmon should be invoked after you have
acquired root privileges. You must also set the DISPLAY environment
variable to the local machine (e.g. :0.0) so that any GL calls that
setmon makes will occur on the local machine, and not over a network
interface.
Command line options are:
-n Specifies that format should not be saved in eeprom
and used as the default, but should just be loaded
temporarily. This is the opposite of the -x option.
-x On RealityEngine graphics, this saves the specified
format in the eeprom on the display board. On IMPACT
graphics, the name of the format is stored in
/var/X11/Xvc/Impact<pipe>_TimingTable, where
is 0 or 1. This format does not take effect
immediately; it is only used the next time graphics
is initialized, or the system is powered up. To
initialize graphics, use (/usr/gfx/stopgfx;
/usr/gfx/startgfx) &
-g Enables genlock (external video clock).
-t Specifies that genlock input operates at TTL levels
rather than nominal video levels (only applicable
when genlock is specified).
-T Specifies that sync output should be at TTL levels
rather than nominal video levels. Currently only
supported on RealityEngine; other systems default to
TTL levels.
-G Specifies that genlock input is through the GREEN
input rather than the SYNC input (only applicable
when genlock is specified).
-ssyncselect Specifies the source of the sync signal. syncselect
is any combination of "r", "g", "b", and "a" to
represent the sync signal on the same combination of
the red, green, blue, and alpha video cables. If
syncselect is "n", the sync signal will be generated
on the sync cable. If syncselect is not specified,
Page 1
SETMON(1G) SETMON(1G)
the sync signal will default to the green cable.
-jgenlockdelay Specifies number of pixels to adjust display,
relative to genlock input signal. Currently, only
supported on Iris Elan and Extreme for NTSC and PAL
monitors. Positive values move display to the left,
and negative values move display to the right. Must
be used with the -g option.
-Finput_signal Specifies if input signal used for framelocking is
interlaced or non-interlaced. input_signal is "n" for
non-interlaced and is "i" for a interlaced input
signal. If input_signal is not specified, the input
signal setting will default to non-interlaced for
backward compatibility. On Indy graphics systems,
specifies whether the input signal used for
framelocking comes from Vino (-Fv) or Galileo (-Fg)
video. On Indigo2 XL systems, specifies whether the
input signal used for framelocking comes from the
backplane (Fv) or Galileo (-Fg) video. On Indigo2
IMPACT systems, specifies whether the input signal
used for framelocking is an internal (-Fi) or
external (-Fe) (i.e. video) signal.
-mwidthxheight Specifies the area that the X server should manage;
this may be larger than the area output by format. If
not specified, this defaults to the area required by
format. This is currently only supported on
RealityEngine.
-S For use only on machines with Reality Engine
graphics. Specifies the Multi-Channel Option should
be enabled. You must specify a format which is
appropriate for MCO; the available formats are
described in the documentation accompanying this
hardware option.
-v Enable verbose mode. On systems supporting custom
video output formats, statistics related to
downloaded file size and compression are printed.
-p pipenumber Specifies the pipe for which the format is to be
changed on systems with multiple graphics pipes. If
the pipenumber is not specified with this command
line option, the pipenumber is otherwise derived from
the trailing digit of the DISPLAY environment
variable. For example, :0.0 refers to pipe 0, :0.1
refers to pipe 1, and :0.2 refers to pipe 2. On
Indigo2 IMPACT systems, this option must be used with
the -x option when invoking setmon without the X
server running.

-c framelock master or slave
Implemented only on Indigo2 XL-XL dual-head. Use "m"
to set the master and use "s" to set the slave head
if you want to change the default settings for
framelocking through the backplane. By default, the
bottom (pipe0) graphics board will be the master and
the top (pipe1) board will be the slave. The master
sends out a framelock sync signal to the backplane.
The slave receives the framelock sync signal from the
backplane. Make sure the pipe number is set for the
appropriate board. Read the above -p description
about setting pipe numbers. Use (-Fv) to framelock
the slave to the sync from the backplane. Use (-Fg)
to framelock the master to the Galileo, assuming the
video board will be attached to the master. Refer to
the galileo man page for more details on framelocking
to the video board.
format Specifies the desired video output format. There are
several supported video output formats. These formats
are dependant on the graphics subsystem.
XS, XZ, Elan, and Extreme Graphics
options support 30HZ, 50HZ, 60HZ, 72HZ, NTSC, PAL,
IRIS3K, STR_RECT, STR_BOT, STR_TOP and 343.
Personal Iris G and TG Graphics
options support 60HZ, 30HZ, NTSC, PAL, and STR_RECT.
STR_BOT and STR_TOP are supported on RE2 and RE2
turbo only.
Entry/Starter Graphics
option only supports 60HZ.
Indy/XL Graphics
supports 50HZ, 60HZ, 70HZ, 72HZ, 76HZ, NTSC, PAL,
IRIS3K, STR_RECT, STR_BOT, and STR_TOP. It also
supports video format files available in the
/usr/gfx/ucode/NG1/vof directory. Naming convention
is the same as described for RealityEngine.
GT and GTX Graphics
support 30HZ, 60HZ, NTSC, PAL, and 30HZ_SG.
GT and GTX RV2 Graphics
support 30HZ, 60HZ, NTSC, PAL, 30HZ_SG, 343 and
STR_RECT.
VGX and VGXT Graphics
support 30HZ, 60HZ, NTSC, PAL, HDTV, STR_RECT,
STR_BOT, STR_TOP and 343. These graphic subsystems
also support custom video formats, which are
Page 3
SETMON(1G) SETMON(1G)
available in /usr/gfx/ucode/vof/dg1 directory.
VTX, RealityEngine, and RealityEngine2 Graphics
support a different naming convention for format.
Video formats are named according to the following
convention:
widthxheight_framerate
For example, 1280x1024_60 implies a video format that
is 1280 pixels wide, 1024 pixels high and runs at 60
Hz. Letters added at the end of a format name signify
special options: i for interlaced, s for stereo, q
for field sequential, f for framelocking, and k for
special alternate formats respectively. Video format
control files are stored in the
/usr/gfx/ucode/RE/dg2/vof subdirectory. A
description of the formats shipped with a release may
be found in /usr/gfx/ucode/RE/dg2/vof/README. As a
convenience, setmon also understands 60HZ, 30HZ,
NTSC, PAL, 343, HDTV, VGA, 72HZ, STR_RECT, STR_BOT
and STR_TOP, and converts them to the correct file
name.
IMPACT Graphics
uses the same naming convention as VTX,
RealityEngine, and RealityEngine2, but video format
control files are stored in /usr/gfx/ucode/MGRAS/vof
for High and Solid IMPACT, and in
/usr/gfx/ucode/MGRAS/vof/2RSS for Maximum IMPACT.
Format file names end with a '.sdb' extension that
should not be used when specifying a format to
setmon. For IMPACT Graphics, a 'p' at the end of a
format name indicates that the format is for use on
systems equipped with a Presenter Flat-Panel Display
adapter. An 's' at the end of a format name
indicates that the format allows the use of stereo
visuals. Formats ending in '_32db' allow the use of
deep (32-bit) double-buffered visuals. Format names
ending in '_pbuf' allow programs to allocate pbuffers
in the Z bitplanes of the framebuffer. As a
convenience, setmon also understands 50HZ, 60HZ,
72HZ, 76HZ, STR_RECT, STR_BOT and STR_TOP, and
converts them to the correct file name.
Infinite Reality Graphics
support not just simple video formats, but video
format combinations. Because Infinite Reality always
operates as a multiple channel device, a video format
describing a single channel is insufficient to
describe the operation of the entire video subsystem.
Instead, setmon uses a combination file - a file
Page 4
SETMON(1G) SETMON(1G)
describing frame buffer layout and formats for all
channels - as the format parameter. You can build
combination files with a program, ircombine(1g), that
assembles an ensemble of formats.
You will find a number of pre-built combinations in
the directory /usr/gfx/ucode/KONA/dg4/cmb. The names
of these files is sometimes precisely descriptive of
their content, but a full analysis of the files
should be extracted via ircombine(1g). You must copy
all user-defined combinations to this directory to
load them.
For backward compatibility, setmon supports a set of
pre-built combinations that contain only one format
each. These combinations are named similarly to that
of the corresponding formats used on Reality Engine.
The NTSC and PAL video formats are actually the 525 and 625 line
component RGB formats, and are not the composite video formats that
these names imply.
To get composite video output from other systems, you may choose to
purchase an encoder option such as the CG3 or BVO (which encodes the
525 or 625 component RGB formats into true NTSC and PAL
respectively), or a video peripheral product which provides
composite output from an external frame buffer.
The setmon command does not control the composite output of
RealityEngine, which is controlled by the vout command. For
InfiniteReality, it is controlled by the ircombine(1g) command.
On systems that support custom video output formats, a user-defined
format may be selected by placing the file containing the VOF into
the appropriate /usr/gfx/ucode/vof subdirectory. A given user-
defined format may then be selected by specifying the file name as
the format argument.
EXAMPLES
/usr/gfx/setmon -s g 30HZ
sets the video output format to 30 Hz, sync-on-green.
/usr/gfx/setmon -x 1280x1024_60
sets a RealityEngine or IMPACT to run 1280 x 1024 at 60Hz non-
interlaced resolution the next time graphics is initialized.
/usr/gfx/setmon -x -s b 640x480_180q
Page 5
SETMON(1G) SETMON(1G)
sets a RealityEngine to run 640 x 480 x 180 Hz color field
sequential output with sync on blue when graphics is next
initialized.
/usr/gfx/setmon -g -s rgb vof3
sets the video output format to the VOF contained in the file vof3.u
found in the appropriate /usr/gfx/ucode/vof subdirectory. The
format is genlocked and with sync-on-red/green/blue.

NOTES
When changing to a different resolution than the X server was started
with using /usr/gfx/setmon -n, X does not know of the change, and will
continue to manage it's original resolution. The displayed area is tied
at the lower left hand corner of the managed area. This may cause some
confusion with the cursor position along the top and right hand edges of
the screen.
On IMPACT, some formats may not be loadable using /usr/gfx/setmon -n,
because those formats require its notion of the screen resolution or the
available visuals. To change to these formats, it is necessart to use
/usr/gfx/setmon -x and restart the X server.
In addition, the pixel depth on RealityEngine is not changed by
/usr/gfx/setmon -n. To change pixel depth it is necessary to use
/usr/gfx/setmon -x and restart the X server.
The -x option is only supported on RealityEngine and IMPACT.
The -F option is only supported on the IMPACT, Indy, XL, and Elan and
Extreme family.
The -p option is only supported on RealityEngine and IMPACT.
On Iris Elan and Extreme, the X server must be running before using
setmon. On IMPACT graphics, setmon must be run with the -x and -p options
if the X server is not running.
On Elan and Extreme systems, sync appears on the red, green, and blue
signals, by default. On the Extreme and Indigo2 XZ, you can use the -G
and -s <r,g,b,n> options. Sync is always on the sync pin.
Iris Elan and Extreme also support adjusting the genlock delay, with the
-j option.
/usr/gfx/setmon -g -j 10 NTSC
Page 6
SETMON(1G) SETMON(1G)
sets the video output format to NTSC, and adjusts display by 10
pixels to the left, relative to the genlock input signal.
/usr/gfx/setmon -g -j -10 NTSC
sets the video output format to NTSC, and adjusts display by 10
pixels to the right, relative to the genlock input signal.
STR_BOT is used to turn on full-screen stereo, and signals the X server
that the bottom half of the screen is to be displayed as the primary
buffer. STR_TOP is used to turn on full-screen stereo, and signals the X
server that the top half of the screen is to be displayed as the primary
buffer. STR_RECT turns on full-screen stereo, but does not inform the X
server of the fact, which gives the old full-screen stereo behaviour.
/usr/gfx/setmon -cs -Fv 1280x1024_50
With the DISPLAY environment variable or the -p option set
appropriately, the "-cs" changes the Indigo2 XL board to a slave and
the "-Fv" framelocks the slave to the sync signal coming from the
backplane of the Indigo2. If the board is the slave by default, you
don't need the -c option. Type "/usr/gfx/gfxinfo" to see the default
settings.
/usr/gfx/setmon -cm -Fg 1280x1024_50
The "-cm" sets the Indigo2 XL board to a master which sends a
framelock sync signal to the backplane of the Indigo2. The "-Fg"
framelocks the master to the video board which is assumed to be
attached to the master board. If the board is the master by
default, you don't need the -c option. Type "/usr/gfx/gfxinfo" to
see the default settings.
