NVIDIA 3D Vision: What can I do, when 3D Vision is not Working?

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 (only for notebooks with external IR emitter).
Check and make sure that stereoscopic 3D is enabled. Go to the NVIDIA Control Panel Set Up Stereoscopic 3D screen.
Re-evaluate your setup. Ensure there is direct line-of-sight between the IR emitter and your wireless 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. 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.
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 3D Vision. Then select Run Setup Wizard from Test Stereoscopic 3D drop down menu.
Ensure your wireless 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 60 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.

If you are charging the wireless 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, the wireless 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 or enable Toshiba USB Sleep&Charge.
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 (only if a external 3D ready display is connected to your notebook PC).
