Assigning Configurations to Games
If only one version of a game contains configuration settings, such as the demo or full 
game version, you can apply the settings to another version of the game. For example, if 
the demo version looks good with the current configuration, the full game version should 
also look good with the same configuration. 
To use a particular configuration for another version of the game, or for another game:
1Find the listed configuration.
aFrom the Stereo Properties sheet, click Game Configuration.
bScroll through the Game Name list to find the configuration you want to use, then 
click it.
cClick the Advanced Settings ... button to open the Advanced Game Configuration 
sheet.
2Select the game to assign to the configuration.
aIn the Advanced Game Configuration sheet, click the Change... button.
bLocate the new game executable file and select it.
cClick Open.
The current configuration is now assigned to the chosen game.

About the Stereo Viewer
Functional Overview
The NVIDIA 3D Stereo Driver comes with a Stereo Viewer application for viewing and 
manipulating static stereo images. The Stereo Viewer is designed to display images 
created using the NVIDIA stereo image capture utility, and can also display JPS images 
from other sources, H3D images, left and right image sets of JPEG images, and anaglyph 
JPEG images. 
The following sections describe the capabilities of the NVIDIA Stereo Viewer: 
“Capturing Images” on page 31
“Viewing Images” on page 32
“Setting Resolution and Gamma” on page 36
“Viewing a Set of Images as a Slide Show” on page 36
“Moving the Image Files” on page 38

Viewable Images 
Table 4.1 lists the types of files that can be viewed with the Stereo Viewer, and provides a 
brief description of applicable requirements.
Capturing Images
The NVIDIA driver includes a stereo image capture function that takes a snapshot of a 
stereo video or game. It saves page flipped images as a JPS file, and anaglyph stereo 
images as a JPEG. 
To capture a stereo image, press Alt+F1 while playing a game in stereo.
 The hot key for “Save Image” is defined under the Stereo Properties > Additional 
Properties sheet. 
 The driver assigns the image a sequential filename based on the original application, 
and stores it in the folder Nvstereo.img. 
Table 4.1File Types Viewable with the Stereo Viewer 
File Type (extension)Stereo TypeComments
JPEG Stereo (.jps)Page Flipped Created by the Stereo Capture utility from page flipped 
stereo, or provided by an outside source. Regular JPEGs 
that consist of a side by side image must be renamed with 
the .jps extension in order to be viewed as a stereo image.
JPEG (*l.jpg or *r.jpg))Page Flipped Both “left” and “right” image files are viewed as a set. 
Both filenames must be identical except for the last letter. 
When one of the files is opened (see “Viewing Images” on 
page 32) the Stereo Viewer searches for the 
complementary file in the same directory and opens both 
files. If a complementary file does not exist in that 
directory, the first file is opened without any stereoscopic 
properties. 
H3D (.h3d)Page Flipped Must be a true H3D file, and not another file type renamed 
with the .h3d extension.
JPEG (.jpg)Anaglyph Created by the Stereo Capture utility from anaglyph stereo, 
or provided by an outside source. JPEG files that are not 
anaglyphs are opened without any stereoscopic properties.

Starting the Viewer and Opening an Image File
Procedure
1Start the Stereo Viewer.
In the Stereo Properties sheet, click the Stereo Viewer box. 
Figure 4.1Starting the Stereo Viewer

Load the left and right eye views into the Stereo Viewer
Option 1: Loading Both Eyes Simultaneously
aFrom the NVIDIA Stereo Viewer window, click File->Open ...
Hot Key—Ctrl+O
bLocate and choose a stereo file (.jps, .h3d, or .jpg), then click Open.

Using the NVIDIA Stereo Viewer
Both left and right images are displayed in the Viewer window. 
Figure 4.2Stereo Viewer—Windowed View

JPS and true H3D files are treated as page flipped stereo images, with the left and 
right images corresponding to each respective ‘page’.
If a JPEG file is opened and the filename contains the letter ‘r’ before the extension, 
the Viewer searches for a similar filename that contains the letter ‘l’ instead of ‘r’. 
Conversely, if the filename that is opened contains the letter ‘l’ before the extension, 
the Viewer searches for a similar filename that contains the letter ‘r’ instead of ‘l’. 
The Viewer then opens both files and treats them as a single page flipped stereo 
image.
Example filenames: 
NVIDIA_l.jpg and NVIDIA_r.jpg.
Other JPEG files are not treated as stereo images, and the left and right images will 
be identical. However, you can use the stereo viewer to open and view anaglyph 
JPEGs without the need for paint programs or other graphics viewers. 
Option 2: Load Each Eye Individually
Pairs of JPEGs that are stereoscopic when viewed alternately (page flipped) can be 
loaded into each eye of the Viewer individually. 
aClick in one of the ‘eyes’ of the Stereo Viewer window, then choose Load Eye from 
the menu.
bLocate the JPEG that corresponds to the ‘eye’ you clicked (left or right), select it, 
then click Open.
cRepeat steps a and b for the other eye view.
3Click View > Stereo View to see the full-screen stereo display of the image.
Hot Key—Ctrl+V
4When finished viewing, press the ESC key to return to the windowed view.
If left/right “black eyes” do
not appear, resize the Viewer
window.

Type of ImageHow to View
JPS or H3D ImageJust open the file. 
The Stereo Viewer places the left side of the 
image in the left eye position and the right side 
of the image in the right eye position.
Set of Left and Right JPEGs—Method AIf the filenames for the left and right eyes are 
identical except for the ‘l’ and ‘r’ designation 
right before the extension, then open one of the 
files with the Stereo Viewer. 
The Viewer opens both files and places the ‘l’ 
file in the left eye position and the ‘r’ file in the 
right eye position.
Set of Left and Right JPEGs—Method B You can place any two JPEG files in the left and 
right eye positions one at a time. 
For each eye view, right click in the 
corresponding Viewer window, choose Load 
Eye from the menu, then select the JPEG file 
you want to use for that eye view. 
Anaglyph JPEGJust open the file.
Instead of opening another graphics application, 
you can use the Stereo Viewer as a graphics 
viewer for JPEGs. 
Since the left and right eye views are identical, 
the image does not have stereo properties unless 
it is an anaglyph.

Reversing Left and Right Page Flipped Images
Page flipped images created by the NVIDIA stereo image capture utility will display 
correctly. Images obtained from other sources, however, may be designed for cross-eyed 
viewing and will not display correctly. In this case, the left and right images must be 
switched. To do this: 
Open the stereo image, then from the main menu click View->Swap Eyes.
Hot Key—Ctrl+W
The left and right images will switch positions. This effects the display of the current 
image only, not the image file itself.
Note: The stereo viewer cannot reverse the display of JPEG images. However, anaglyph 
displays of JPS or H3D images can be reversed. 
Viewing Page Flipped Images as Anaglyphs
To view a JPS file as an anaglyph—
1Open a JPS file. 
2Switch the display type using any of the following methods: 
From the main menu, click View->Switch Display Type.
Press the hot keys Ctrl+T
From the main menu, click View->Option, then in the Display Settings section of the 
the Options page choose Anaglyph and click OK or Apply. 
The viewer display changes from page flipped to anaglyph.  
3Click View->Stereo View to view the full-screen anaglyph stereo image.
Hot Key—Ctrl+V
Note: You can convert the page flipped file to an anaglyph JPEG . While viewing the 
image in full-screen anaglyph stereo mode, save the image as an anaglyph JPEG 
using the stereo capture utility (Alt+F1).
