2.1 Firmware Update

In order to support active stereo please ensure that you have correct firmware.

For more details see user manual of HMD and user manual of HMD_connection software.

You can find needed Software, firmware and manuals here: www.trivisio.com/index.php/support/user-manuals www.trivisio.com/index.php/support/software

Follow the process in correct order: Go to “Firmware update” tab of HMD_CONNECTION software.

1. Update main firmware of HMD (Atmel) . For devices with 42FOV optic use files:

SVGA_LVC_Bino_DVI_0x0010.eep SVGA_LVC_Bino_DVI_0x0010.hex

For devices with 29FOV optic use files:

SVGA_LVC_Bino_DVI_0x0011.eep SVGA_LVC_Bino_DVI_0x0011.hex

2. Update Display_Engine firmware (Xilinx) and Active_Stereo_Engine (for devices which support active stereo). For devices with 42FOV optic use files:

display_engine_0x0010.bin active_stereo_engine_0x0010.bin

For devices with 29FOV optic use files:

display_engine_0x0011.bin active_stereo_engine_0x0011.bin

2.2 Working with nVidia GeForce

USB IR emitter from 3D VISION WIRELESS GLASSES KIT is needed to activate active stereo driver in frame sequential mode for 120hz.

Active Stereo User Manual 5

The driver for emitter must be installed prior to connecting the USB IR Emitter. Connect IR Emitter to USB. Open nVidia Control Panel. Go to Stereoscopic 3D folder. Select Generic CRT display.

Then check the box Enable steroscopic 3D ,you'll be run through Setup Wizard. On unknown reason during the process Wizard is not running 120Hz active stereo, so to answer correctly to prompts there please select following to complete setup.

Once it's done you can run nVidia sterescopic 3D test. Select 120Hertz and Launch Test Application.

Active Stereo User Manual 7

Note: Be sure to correctly close application you need either click Close or type Esc. This way driver switch from stereo 120Hz to mono 60 Hz. All other incorrect ways will leave 120Hz running in mono mode.

Now you can close nVidia Control Panel and run stereo application you want to work with. It might be nVidia 3D Vision Viewer, browser for HTML5, etc.

To keep correct eye layout on HMD we capture IR signal from IR emitter. Dongle contains IR receiver, photodiod placement is shown on the picture.

Locate IR emitter somewhere around to dongle but not closer then 30 cm to it.

Note: For some old devices (dongle is not equipped with IR receiver) we don't use stereo signal from IR emitter, so there is no lock to stereo sequence. Thus if you run 3D application and observe wrong stereo picture just use Hot Key Ctrl+W to swap to right eye layout.
