There are LCD HDTVs that are on the market that claim to display at 120 to 240 Hz refresh rate. These type of displays use framerate conversion or backlight flashing to convert 60 Hz signals to 120 Hz or above. This technology is incompatible and Not 3D Vision Ready. Shutter-based 3D stereocopy relies on two completely different images (one for each eye) being displayed in alternating order that is compatible with the NVIDIA 3D Vision kit.
Please see the 3D Vision System Requirements for a full list of 3D Vision—Ready displays. http://www.nvidia.com/object/GeForce_3D_Vision_Requirements.html
Displays not listed are not certified and thus not compatible.
