There are two types of drivers for the glasses. The nvidia stereo drivers and the edimensional drivers. Nvidia users can use either one, but not both at the same time. The glasses work as follows: First the software analyzes a game and converts it to a 3-D mode, the way you know if this step works is the screen will look blurry when you take off the glasses. Next, put on the wired or Wireless (for wireless hit the ON button on the top of the left lens, it's only an ON button so hitting it 2 times will not turn it off, just on again). The glasses lenses should get a little darker and start flickering at an extremely fast rate which can be undetectable to the eye. When the screen is blurry and the glasses flicker then it will be 3-D as it should. If the first part is not working then there is a software problem and reinstall the drivers or make sure it's a compatible game, try other games, etc. If the second part doesn't work and the glasses don't come on it's hardware and change the batteries, move closer to the transmitter and for wired unplug and plug back in. Once the image looks 3-D use the hotkeys to adjust the image so it changes to look the way you would like.
