In a Projection VR system, the projector displays 120 images per second, alternating between left and right images. The shuttering of the glasses occurs in sync with the projectors so that each image is seen by only the left or right eye. The human visual system combines these images to create the 3D stereo effect. The graphics card/sync card sends the sync signal to both the projector and 3D glasses emitter. The emitter sends the sync signal to the glasses resulting in a sync between the projected images and the glasses. Volfoni 3D Glasses
Volfoni receiver There are two receiver connections. Use the 3 pin DIM to 2.5mm audio connector to connect the receiver to the sync card / video card on the rendering computer. Use the USB to micro USB to connect the receiver to the USB power plug or computer (to provide 5V DC power). The emitter's blue led will blink twice every few seconds when emitting RF. Documentation Below is a link to the manufacturer's documentation on the 3D glasses. The troubleshooting guide (section 7) covers common issues with the glasses http://volfoni.com/wp-content/uploads/2015/09/manual_edge_rf_eng.pdf Syncing and Stereo Issues Follow the steps below to fix most syncing and stereo issues: 1) Open the Nvidia control panel and go to 'Change resolution'. The resolution and refresh rate for the Christie projector should be: 1280 x 720 @ 120Hz. 2) Go to 'Manage 3D settings' and verify 'Stereo - Enable' is set to 'On' and 'Stereo - Display Mode' is set to 'On board DIN connector'. 3) Verify 3D is enabled in the Christie projector menu. 4) Verify the channel has not changed on the bottom of the emitter. It should be set to channel 8. Verify on the glasses the switch near the button is set all the way forward. It has three possible positions. 5) If the emitter does not blink twice every few seconds when the script is running first restart the script. 6) If that does not work, with Vizard script closed down, unplug both the USB and Sync cable from emitter to machine and replug. Then run Vizard again and see if the emitter blinks twice. You may need to press the button on upper left of glasses to reconnect. 7) Power cycle the machine. 8) Try to eliminate any possible sources of interference if you still have issues. RF interference could be caused by other RF devices or WiFi. This could interfere with sync and cause flickering or color shifts. 9) If glasses are syncing but the stereo effect does not look quite right, you could try changing the 'Stereo Swap' setting in the Nvidia control panel > 'Manage 3D settings' list. 10) If stereo looks correct on one display but not another:
