Its actually not supported by the monitor. While the monitor says its "3d". What it really means is that it will take a 2d input and convert it to 3d through the monitor. In order for 3d to work through the Nvidia GPU you will need a monitor with a refresh rate of 120hz or higher, as well as needing either a monitor with built in 3d Vision 1/2 sensor with glasses, or by having a Nvidia 3d Vision Kit. Your monitor's optimum refresh rate is 60hz @ 1080p which is not recommended for nvidia 3d.
I'm sorry to say but your monitor is not supported of proper nvidia 3d viewing.
