The graphics card will try
VESA Standard refresh
rates, if the display device
does not support 110 Hz at
the specified resolution.
The VESA Standard
refresh rates are unlikely
to work properly given
that stereo displays need
higher refresh rates. In this
case, you need to add the
appropriate modelines and
possibly modify the
vertical refresh rate in the
stereo Monitor Properties
files. See Section 3.1.2.3 for
details.

Tip:
The default supported resolutions are meant as a starting point and you should review and add
to them as needed for your display devices. Changes to these tags require regenerating the X
Config Files as described in Section 3.1.2.3.2. The values for these tags determine valid resolution
options for the SVA launch scripts.
If the display device you want to use with your cluster requires an unsupported resolution, you
need to add it to the Site Configuration File. You do this by modifying the value for the appropriate
tag (mono or stereo). See the SVA System Administration Guide for information on how to modify
the Site Configuration File.
For example, if you want to use a stereo display device that requires 1600x1400 at 110 Hz, you
would modify the SVA_SUPPORTED_STEREO_RESOLUTIONS as follows:
SVA_SUPPORTED_STEREO_RESOLUTIONS="1280x1024,1920x1200,1600x1200,1400x1050,1280x960,1152x900,1024x768,1024x768_60,800x600,640x480,1600X1400"
Note the addition of the 1600X1400 resolution to the end of the line.
You would also need to edit the X Config Monitor Properties File to make sure the correct
modelines are available for this new resolution and its vertical refresh rate as described in
Section 3.1.2.3.
3.1.2.3 Work with X Server Config Files for Your Displays
X Config Files are an accepted and common mechanism needed to display images (mono and
stereo) on display devices. The X Config Files on SVA nodes must accurately reflect the various
properties of the attached display device, for example, vertical refresh rate, horizontal sync, and
modelines.
During the imaging part of the SVA installation, SVA generates its own set of X Config Files in
/etc/X11. These files are usually fine for handling typical desktop display devices, for example
mono flat panel displays. However, for more exotic mono displays, and often for stereo displays,
you may need to change some property settings in the X Config Files. If your display device fails
