LCD shutter glasses appeared in the 1980s, one example of which is Sega's SegaScope. This was available for Sega's game console, the Master System. The NVIDIA 3D Vision gaming kit introduced in 2008 made this technology available for mainstream consumers and PC gamers. The kit is specially designed for 120 Hz

Stereo driver

The stereo driver software can perform automatic stereoscopic conversion by using the 3D models submitted by the application and rendering two stereoscopic views instead of the standard mono view. The automatic driver works in two modes: fully "automatic" mode, where 3D Vision driver controls Stereo Convergence (Pop Out) and

Discontinuation of support

On April 11, 2019, Nvidia announced that support for 3D Vision in drivers would be discontinued, as well as support for 3DTV. Driver releases after version 425.31 do not include support for 3D Vision.
