Hide Stereoscopic 3D Effects When Game Starts
There are some games that do not launch ver y well when stereoscopic 
3D effects are enabled at star tup. To avoid this, check the box on 
the Set Up Stereoscopic 3D screen in the n VIDIa Control Panel.
The stereoscopic 3D effects remain enabled, it is just hidden at 
star tup. o nce the game has loaded, you can show stereoscopic 
3D effects by pressing the Stereoscopic 3D ON/OFF button 
on the Usb IR emitter on button, pressing the notebook's 3D 
on/ off button, or by using the keyboard shor tcut Ctrl-T.

Test Stereoscopic 3D
The Test Stereoscopic 3D button and drop-down list on the Set Up  
Stereoscopic 3D screen in the n VIDIa Control Panel provides the ability  
to test stereoscopic 3D viewing and the ability to run the s etup  
Wizard and the medical Image Test.
Test stereoscopic 3D o ption
Clicking on the Test Stereoscopic 3D... button 
displays a test application that allows you 
to adjust stereoscopic 3D effects so that 
watching 3D Vision is comfor table to you. 
Click Launch Test Application after you select the display settings.
The image displays in full-screen if you have the correct 
resolution set for you monitor. With your wireless glasses on, 
you are able to see in stereoscopic 3D. Use the shor tcut keys

Note: any changes made using the shor tcut keys or the IR emitter depth wheel is reflected on the Set Up Stereoscopic 3D screen..
When you have finished any adjustments, press the 
Esc key to exit the stereoscopic 3D test screen.
Run s etup Wizard o ption
Clicking on the dropdown menu icon displays the Run Setup 
Wizard and Run Medical Image Test options. selecting the 
Run Setup Wizard option launches the Wizard so that you 
can make changes to your configuration or add displays.
Run medical Image Test o ption
The medical Test Image is run during the install Wizard (see s tep 20  
on page 22). However, you can run the test independent of the 
Wizard by selecting the Run Medical Image Test option. 
Attention: nVIDI a recommends that ever y new stereoscopic 3D user run the m edical Image Test to verif y their ability to view stereoscopic 3D-rendered images. If you can not see the image, do not use 3D Vision (see step 20 on page 22).
View Compatibility With Games
nVIDI a has tested and provided profiles for many of the top selling 
games to ensure they work properly with 3D Vision. a ll games that 
have been tested are listed in the nVIDIa Control Panel with their 
compatibility rating. e ach game has been rated with Excellent, 
G o o d ,  F a i r, or Not Recommended. These ratings are based on how 
well the games play in stereoscopic 3D and if there are any issues 
in the game that may inter fere with your 3D Vision experience.

Issues and settings recommended by nVIDI a as a result of testing.
If you have a game that is not on the list of those tested by n VIDIa,  
go to w w w.nvidia.co.uk and consult the games that have been tested  
since the release of this version of software.
To see any issues and to view recommended setting that n VIDIa 
discovered when testing a game, select (highlight) a game in the 
list and see the instructions listed under Issues and recommended 
settings. To view a game in the best possible stereoscopic 3D, 
you must follow the recommended settings. n ot following these 
settings could result in the game not running in stereoscopic 3D. 
You can also use the shor tcut keys Ctrl+Alt+Insert to display the 
recommended settings as an overlay on the opening screen of a game.

The nVIDIa 3D Vision Driver takes certain 3D information 
contained in the game and uses it to generate the 
stereoscopic 3D display. s ince most games are not 
designed with stereoscopic 3D in mind, the resulting 
display quality varies from game to game. In some cases, 
the game is not viewable at all in stereoscopic 3D without 
making adjustments based on obser vation.
optimum stereoscopic 3D is achieved when the game display consists 
of the following:
 >m eaningful range of depth, or distance between the nearest and 
farthest objects.
 >nearest objects which are not too close for comfor table viewing.
 >Heads up displays (HUD) that are positioned so as not to inter fere 
with the stereoscopic 3D experience. Ideally, HUDs should be at 
screen depth.
Preset Configurations
for most games, n VIDIa has established settings that adjust the 
display to achieve high quality stereoscopic 3D, based on the needs of 
each game. 
You can view the list of these games on the View compatibility with 
games task located on the n VIDIa Control Panel. This menu also 
shows a list of comments per taining to that game. These comments 
may include suggested settings or adjustments and comments on the 
construction of the game. These instructions can also be overlaid on 
the opening screen of the game using Ctrl+Alt+Insert.
be sure to view these comments before you begin your game.

Viewing Practices 
 >Depth Amount: The recommended star ting point for Depth 
amount is 15%, but always adjust the depth to a comfor table level. 
You can increase it over time as your eyes get used to stereoscopic 
3D viewing.
 >Viewing Distance: m aintain a distance no closer than 2 to  
2.5 feet away from the monitor. Viewing from too close a 
distance can cause too much strain on your eyes, and can reduce 
stereoscopic quality.
 >Viewing Angle: Keep your eyes parallel to the screen. The imagi-
nar y line connecting your eyes should be parallel to the horizontal 
level of the screen. The stereoscopic 3D effect is based on side-
to-side or horizontal—displacement of each image. If you tilt your 
head, your eyes no longer see the displacement as horizontal, and 
the stereoscopic 3D effect is diminished or even eliminated. While 
your brain may adjust to this viewing, it must work harder, result-
ing in eye strain and fatigue.

 >Viewing Time: Take regular breaks. a s with any time spent look-
ing at a computer screen, it is good practice to give your eyes a 
rest after a period of time. a t a minimum, rest for five (5) minutes 
after ever y hour of stereoscopic 3D viewing. 
 >Viewing with Prescription Glasses: If you normally wear glasses 
when viewing a computer screen, keep them on and put the wire-
less glasses over your eye wear. The sharper the image on the 
screen, the better the quality.
 >Game Cursor/Cross-hair Sights: If you are using the nVIDIa 3D 
laser sights, be sure to turn off the sight that the game provides. 
The game sight is usually positioned at screen-depth, and inter-
feres with useful viewing of the n VIDIa laser sight.
 >Display Lighting: The amount of light reaching each eye is cut in 
half, and causes the screen to appear darker under stereoscopic 
3D viewing. a djusting the brightness and contrast settings of your 
game can also reduce screen persistence and improve stereo-
scopic 3D quality.
 >Ambient Lighting: The intensity of surrounding lighting can affect 
stereoscopic 3D quality and comfor t. l ighting conditions that im-
prove stereoscopic 3D viewing var y from one person to the next, 
so experiment with brighter or darker room lighting to find what 
works best for you. see Tips and Troubleshooting on page 37.
Note: High intensity lighting (especially halogen lighting) can inter fere with IR communication (between the wireless glasses and the IR emitter) resulting in some flicker.
