"While NVIDIA's GeForce 3D Vision glasses are a big part of this new stereoscopic gaming technology, it isn't the only piece of hardware you'll require to get up and running. Traditionally, one of the main downsides of using LCD shutter glasses to create a "true" 3D effect is that flicker is very noticeable - As each eye only receives half of the monitor's refresh rate, running a standard LCD screen at 60Hz through these glasses gives a 30Hz refresh rate to each eye, and I'm sure I don't need to explain to you why this is a bad thing. Thus, to alleviate this flickering issue, one thing required of a GeForce 3D Vision setup is a compatible monitor complete with a 120Hz refresh rate (a couple of which supported by NVIDIA we'll look at briefly later)."
