3D Vision FAQ

3D Vision-Ready LCDs – such as the Samsung SyncMaster 2233Z and ViewSonic® FuHzion™ VX2265wm accept a 120 Hz input and display at 120 Hz refresh rate . There are LCD HDTVs that are on the market display at 120 Hz refresh rate, but only accept a 60 Hz input signal over HDMI or dual-link DVI. These type of displays use framerate conversion or backlight flashing to convert 60 Hz signals into 120 Hz.

Please continue to check the 3D Vision System Requirements for a full list of 3D Vision—Ready displays here.

The NVIDIA 3D Vision stereo driver is only compatible with the NVIDIA 3D Vision glasses. 3rd party glasses are not supported.

This is called overscan mode and is a common mode for DLP televisions set by the HDTV manufacturer. Some televisions have a built in mode called "Reduce" which allows you to view the entire Windows desktop, but this mode is not compatible with stereoscopic 3D gaming.

However, NVIDIA has a Resize HDTV function available in the NVIDIA control panel which allows users to view the entire Windows desktop and is compatible with 3D stereoscopic gaming. To enable it, follow these instructions:

• The options on this Resize HDTV Desktop page appear if you have set the NVIDIA Control Panel View menu to Standard.
• You can resize the desktop appearing on your HDTV screen if your desktop is extending beyond the viewable display area or the desktop or image is not filling the entire display area.
1. From the NVIDIA Control Panel navigation tree pane, under Video & Television, click Resize HDTV desktop to open the associated page.
2. Click the Resize Desktop button.
• Use the slider to increase or decrease the size of your desktop/picture until you get the desired result.

Update: If you are using the HDTV Resize Desktop function with 3D Vision and it is not working for you, please download the 3D Vision DLP Hotfix.

Try selecting a game resolution of 1024x768, 1280x1024 or 1360x768. These resolutions won't be displayed full screen but will still allow you to use 3D Vision.

This issue could be caused by a few things, so its important to describe the different ways to connect your GPU to your DLP.

Using the HDMI connector on the GPU to plug directly into the DLP HDMI input
For this configuration, check to make sure that you have connected the S/PDIF connector from the motherboard to the GPU. Please check with your motherboard manufacturer to ensure it has the correct S/PDIF connector.
If your motherboard does not have a S/PDIF connector and you wish to use the analog output on your motherboard to connect to the DLP, follow the instructions in Using the DVI connector on the GPU to plug directly into the DLP below.

Using the DVI connector on the GPU to plug directly into the DLP using a DVI to HDMI adapter
3D Vision ships with a DVI to HDMI connector that can be used to connect to the HDMI input on the DLP. In order to connect analog audio from your PC to the analog input on the television to use the television's speakers, follow these instructions:

1. Download the 3D Vision DLP Hotfix.
   • Windows Vista 32-bit DLP Hotfix
   • Windows Vista 64-bit DLP Hotfix
2. Connect your PC's analog audio into the analog input on the back of your DLP. Mode DLPs use left and right RCA audio inputs so you will likely need a cable called "3.5mm Stereo Headphone To RCA Adapter Cable" to connect your PC to the DLP.
3. Run the 3D Vision DLP Hotfix. Make sure you are running this as an Administrator on your PC
4. Follow the onscreen instructions to disable HDMI audio. Note that this DLP Hotfix will also toggle the HDTV Resize Desktop compatibility mode.
   For more information on that mode, please read this Knowledge Base article.
5. Reboot your PC.
6. If your DLP requires any changes to its settings, use your DLP remote to configure the audio input.
7. Start up your media player and adjust the volume to a comfortable level.

At this time, the 3D Vision system is supported under Windows Vista only.  Support for other OS's may be possible in the future based on demand.

A dual link DVI cable must be used with the 3D Vision product and 120Hz LCD's.   Example connector below.

Extra NVIDIA 3D Vision glasses will be available from the NVIDIA Store in the future.
http://store.nvidia.com

1. Make sure you have activated the IR emitter. Press the green ON/ OFF button on the front of the emitter. The emitter is on when the button is bright green.
2. Check and make sure that stereoscopic 3D is enabled. Go to the NVIDIA Control Panel Set Up Stereoscopic 3D screen.
3. Re-evaluate your setup. Ensure there is direct line-of-sight between the IR emitter and your 3D Vision glasses at a range of at least 1.5 feet (45cm) or greater. Any obstructions may cause the glasses not to function properly causing the lenses to flicker or turn off.
4. Do not place objects too close or in front of the emitter which could block the signal (e.g. keyboard, coffee mug, etc.). Also, make sure not to place your hand or other objects in front the of the IR receiver on the glasses; located near the front left lens.
5. Run the Setup Wizard to verify your hardware is operating properly. Go to the NVIDIA Control Panel (right click on the desktop). Select Set Up Stereoscopic 3D. Then select Run Setup Wizard from Test Stereoscopic 3D drop down menu.
6. Ensure your 3D Vision glasses are fully charged. You can check the battery level of your glasses by pressing the ON button.
   • If the light next to the button is green, you have up to 40 hours of battery life remaining. Actual battery life is dependent on the recharge time.
   • If the light is red, you have less than two hours remaining and it is recommended that you recharged your glasses.
   • If the light does not turn on, the battery is drained and the glasses must be recharged.
7. If you are charging 3D Vision glasses by connecting them to your PC using a USB cable, make sure your PC does not go into power save mode. When your PC goes into power save mode, 3D Vision glasses are no longer charging. To fix this, disable any power saving options on your PC under the Windows Control Panel. Alternatively, you can use a USB wall charging device to charge the glasses directly from your wall power outlet without connecting to the PC.
8. Make sure you have used the DVI cable that was shipped with your 3D Ready 120Hz LCD display. This is a dual-link cable and 3D Vision will not operate without it.

• Some games actually do natively not support 100hz or higher refresh rates. In some cases it is possible to force the game to use these refresh rates. Please check with the game developer if they support 100 to 120 Hz refresh rates.
• If you are using a 120 Hz LCD make sure you have set the brightness to 100%.
• Be aware that room light, especially flourescent lighting, can make you perceive a lot of flickering. Turn off lights if possible.

To workaround this monitor issue please reduce the display refresh rate to 60Hz.

1. To select a 60Hz screen refresh rate right click on the desktop and click NVIDIA Control Panel.
2. From the NVIDIA Control Panel navigation tree pane, under Display, click Change resolution to open the associated page. *
3. From the Refresh rate list, choose 60 Hertz and apply.
4. Insert Blu-ray disc into the Blu-ray player.
5. Open your Blu-ray / DVD playback software and play the movie.

*Please return the refresh rate setting to 100 to 120 Hertz for proper 3D Stereoscopic use when you're finished viewing Blu-ray movies.

This problem can occur for two reasons:

• Ensure you are using an NVIDIA GPU that supports dual-link DVI. Click Here for system requirements.
• Make sure you are also using a dual-link DVI cable to connect from the LCD to your GPU. Your LCD manufacturer should have included this cable in the original factory box. The connector looks like the image below.

To enable the 3D Vision DLP Hotfix follow these instructions:

1. Download the 3D Vision DLP Hotfix.
   • Windows Vista 32-bit DLP Hotfix
   • Windows Vista 64-bit DLP Hotfix
2. Run the 3D Vision DLP Hotfix. Make sure you are running this as an Administrator on your PC.
3. Follow the onscreen instructions to enable it.
4. Reboot your PC.
5. From the NVIDIA Control Panel navigation tree pane, under Video & Television, click Resize HDTV desktop to open the associated page.
6. Now when you resize your HDTV desktop you can control horizontal and vertical resolution independently.
7. Once you have selected a new Resize HDTV desktop option, this resolution will be added to the Windows Vista and NVIDIA Control Panel monitor resolution options. For instance, a new mode could be 1800x1018.
8. When you run any of your games, be sure to select this new mode when running your game.

In OpenGL, active stereo is explicitly supported through quad buffered stereo as part of the OpenGL API. Quad buffered stereo has the added advantage of enabling stereo-in-a-window while Direct3D APIs do not explicitly support quad buffered stereo. The GeForce driver is specially tuned to deliver active stereo for Direct 3D-based full screen games and 3D movies using the NVIDIA Stereoscopic 3D Movie player software.

Most 3D applications attempt to run on the primary display in full screen mode. This isn't necessarily the display labeled "1" from the Windows Control Panel. To check and make sure you have your 3D Ready display set as the primary display, follows these steps:

Change Primary Monitor

1. Right click on the Windows Desktop and click Personalize > Display settings. // loadTOCNode(2, 'summary'); // On the Display Settings tab of the Display Properties dialog box, click the monitor icon that represents the monitor you want to designate as my main monitor.
2. Click to select the Use this device as the main monitor check box. Note that this check box is unavailable when you select the monitor icon that is currently set as your primary monitor.

A driver will be released in spring 2009 which will enable support for OpenGL Quad Buffered professional 3d stereo using the NVIDIA 3D Vision glasses.

Vsync is required for 3D Stereo, please leave it enabled if you are using your glasses.

If you are experiencing eyestrain or headaches, it could be due to excessive depth amount. Change the depth in one of the following ways:

• In-game adjustment, use the shortcut keys Ctrl+F3 to decrease the depth amount.
• Use the thumb wheel on the back of the IR emitter to adjust the depth amount. If you are new to gaming, start at the default 15%.
• Use your mouse to adjust depth amount on the slider in the NVIDIA Control Panel Set Up Stereoscopic 3D screen If you are new to gaming, start at the default seperation of (15%).

Warning: If eyestrain and headaches persist, discontinue viewing in stereoscopic 3D mode and consult a physician.

3D Vision currently supports 2-way NVIDIA SLI®. A future driver update will support 3-way and Quad SLI technology.

The Test Stereoscopic 3D button and drop-down list on the Set Up Stereoscopic 3D screen in the NVIDIA Control Panel provides the ability to test stereoscopic 3D viewing and the ability to run the Setup Wizard and the Medical Image Test.

Test Stereoscopic 3D Option
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 comfortable to you.
When you have finished any adjustments, press the Esc key to exit the stereoscopic 3D test screen.

Your Eyes might not be adjusted
Your eyes may take some time to adjust to viewing stereoscopic 3D effects. If you are new to gaming, make sure you start your depth amount at the default of 15%. As your eyes adjust, you can increase the depth amount.

Depth Needs Adjusting
Adjust depth amount using the slider on the NVIDIA Control Panel Setup screen. If you are in a game, use the thumb wheel on the back of the IR emitter or the shortcut keys Ctrl+F3 to decrease depth and Ctrl+F4 to increase depth.

The game is not Configured Properly
If your game is not functioning in stereoscopic 3D, look at the list of compatible games shown on the NVIDIA Control Panel View Compatibility with Games screen. Verify that your game has been tested by NVIDIA and has been ranked as Excellent, Good, or Fair. Check out the Issues and recommended settings listed at the bottom of the screen. Make any adjustments recommended by NVIDIA to make your gaming experience better.

If it has a Not Recommended rating, it means that the game does not show in stereoscopic 3D or it shows very poorly. Make sure you are running your game in resolutions that support 3D Vision. In order to support 3D Vision, your game must be configured to run at the correct settings for your display. If you have:

• 120 Hz LCD: Select an in-game resolution of 1680x1050.
• DLP HDTV: Select a resolution of 1920x1080, 1768x992 or 1280x1024 and set the refresh to 60 Hz.
• DepthQ® HD 3D Projector: Select a resolution of 1280x720.

You can test the game in 3D Stereo mode and it may work. However, note that NVIDIA will provide regular driver updates to add new games profiles for the best 3D Stereo Experience. You check to see if your game is supported in the link below.
http://www.nvidia.co.uk/object/3d-vision-3d-games-uk.html

The biggest issues are amount of stereo depth and quality of the game. Reduce the depth amount and see if you are more comfortable by using the depth adjustment wheel on the back of the IR emitter. Over time you may find that you can safely increase the depth amount as your visual system gets used to stereoscopic 3D viewing. Also you should only be playing games with top rating by NVIDIA as issues in a game will produce these negative effects.

Quad Buffered Stereo will be supported with the NVIDIA 3D vision glasses with a new driver in spring 2009.

Quad Buffer Stereo support has been integrated in many professional applications and has broad support. Nearly every major solid modeling/prototyping, molecular modeling, industrial VR and GIS software application supports 3D stereo.

The stereo effect is best in a darkened room and does not work well in bright sunlight.  We recommend that the 3D Vision product should not be used in bright direct sunlight.

Laser Sight is not enabled
If you do not see the laser sight in a game, the laser sight may not be enabled. Go to the NVIDIA Control Panel Set up Stereoscopic 3Dscreen and click on the Change 3D laser Sight button to display the Change 3D Laser Sight screen. Make sure the Enable 3D laser sight for configured games is checked.

Transparency set too High
Go to the NVIDIA Control Panel Set Up Stereoscopic 3D screen and click on the Change 3D laser Sight button. Adjust the Transparency slider to adjust the transparency of the laser sight.

NVIDIA 3D Stereovision glasses use lithium-ion battery technology to provide long life and light weight.

You can recharge the battery whenever convenient i.e. when battery is completely discharged, when red light shows or when not in use. It is recommended that you recharge the battery once per month if glasses are not used.

Like all lithium batteries in use today, the battery in your 3D glasses will slowly age and after awhile it will lose it capability to be charged to it's full capacity. For example, If you fully discharge and recharge your glasses 300 times the battery capacity can full to 80% (that's 6 years before you reach this level if you fully discharge and recharge once a week). The degradation will be slow and will varying depending on your use and recharging habit.

• The recommended operating temperature range is 5 to 40degreeC (41degreeF to 104degreeF).
• The recommended storage temperature range is -10 to 45degreeC (14degreeF to 113degreeF).

Operating and storage of the glasses outside the recommended temperature range can lead to temporary and even permanent damage to the battery and lens of the glasses.

The lithium ion battery in the NVIDIA 3D Stereovision glasses is a custom design. You should not attempt to replace it yourself or by a high street service provider.
Contact NVIDIA or a NVIDIA approved service provider, if you suspect your battery is faulty. For example, if the battery does not give a full day operating time (10hours) after a 3 hour full charge.

Unplug monitor, wait 4 secs and plug back in monitor.  Do not use Dynamic Contrast setting with 3D mode.

The following is a description of what the different light values mean:

• No light - driver is not installed or emitter not plugged into the USB port.
• Flashing red light - emitter plugged in but driver not installed.
• Faint green light - driver is installed properly, but 3D stereoscopic is not active
• Bright green light - driver is installed properly, and 3D stereoscopic is active

The NVIDIA 3D Vision Infrared Emitter shows up in the Windows Device Manager as "NVIDIA Stereoscopic 3D USB controller."

To take a screenshot of your game in 3D, press ALT-F1 when running the 3D game. This captures a compressed stereoscopic JPEG file with a file extension of JPS. These screenshots are stored in the directory C:\Users\[User Account Name]\Documents\NVStereoscopic3D.IMG. In that directory the screenshots will be have the name of the application's EXE (for instance Left4Dead) following by a unique number. Once these screenshots are created you can view them using NVIDIA's Stereoscopic Picture viewer, or send them to your friends to view them on 3D Vision.

You must fully charge your 3D Vision™ glasses for at least three hours before using them for the first time. You can check the battery level of your glasses by pressing the ON button on the left temple.

• If the light next to the button is green, you have up to 40 hours of battery life remaining. Actual battery life is dependent on the recharge time.
• If the light is red, you have less than two hours remaining and it is recommended that you recharge your glasses.
• If the light does not turn on, the battery is drained and the glasses must be recharged.
• If you are charging 3D Vision glasses by connecting them to your PC using a USB cable, make sure your PC does not go into power save mode. When your PC goes into power save mode, 3D Vision glasses are no longer charging. To fix this, disable any power saving options on your PC under the Windows Control Panel. Alternatively, you can use a USB wall charging device to charge the glasses directly from your wall power outlet without connecting to the PC. You can use your glasses while they are charging.

The NVIDIA USB IR Emitter allows users to control 3D functionality. Here is a description of the different functions and colours:

Front of USB IR emitter
The front of the IR emitter has a back-lit button with the following colour codes

• Red – indicates the USB IR emitter is powered but no driver is installed or detected. Make sure you re-install the driver.
• Dim green – indicates that the USB IR emitter driver is correctly installed. This light will remain dim green even with no stereoscopic 3D content running.
• Bright green – indicates that the USB IR emitter driver is installed and stereoscopic 3D is on.

The back-lit button can also be used to turn stereoscopic 3D on and off. Simply press the button and it will switch from bright green to dim green.

Back of USB IR emitter
The back of the USB IR emitter has different color codes and plugs for 3D Vision functionality.

• USB connection – plug the cable from your 3D Vision kit to your computer.
• Power indicator light – indicates that the USB connection to the PC is working and the USB IR emitter is powered on
• Thumbwheel – there is a thumbwheel that can be used to increase/decrease 3D depth in a game.
• VESA stereo cable connection – for use with DLP HDTV displays only. The VESA 3-pin cable must be connected to the DLP HDTV to use 3D Vision.

The 3D Vision USB IR emitter allows for different settings to optimise for your gaming environment. Please follow these guidelines for correct setup on the "Select your Gaming Environment" page of the setup wizard.

• Single PC and 3D LCD display
• NVIDIA recommends selecting the "Single gaming computer setup" from the NVIDIA 3D Vision Setup wizard. This ensures maximum IR coverage by operating in the highest power IR mode.
• This setting is the far left setting in the Setup Wizard.
• Single PC DLP HDTV display
• NVIDIA recommends selecting the one or more gaming computer in a room running 3D Vision with other IR devices (such as remote controls) from the NVIDIA 3D Vision Setup wizard. This ensures maximum IR coverage by ensuring the USB IR emitter works with other IR devices.
• This setting is the middle setting in the Setup Wizard.
• Multiple PCs and LCDs
• NVIDIA recommends selecting the "Multiple gaming PCs in a LAN" from the NVIDIA 3D Vision Setup wizard. This ensures the IR coverage is decreased and isolated to users sitting directly in front of the PC.
• This setting is the far right setting in the Setup Wizard.

Yes, 3D Vision ships with a standard nose piece and two additional interchangeable nose pieces. Simply pull out the current nose piece and insert the one that fits you best.

There are a few troubleshooting steps to check to ensure everything is working properly

• Make sure your display is listed as a 3D Vision-Ready device from the 3D Vision System Requirements webpage. If your display is listed there, then it is an official 3D Vision-Ready device. If it is not listed, then your product will not work with 3D Vision.
• If your product was listed on the 3D Vision System Requirements page, it is possible you are simply using an older driver. Make sure you download the latest NVIDIA GPU and 3D Vision drivers from NVIDIA at www.nvidia.co.uk/drivers.
• If you have updated your drivers and are still having problems, please contact NVIDIA Support for assistance.
