you both of guyz confusing me
I think they're trying to say this.
On a 60Hz monitor, whilst playing 3d the refresh rate (60Hz) gets split into halves. (30Hz) and (30Hz), one for each eye, this is because the monitor is displaying 2 images at a time (according to alithegreat). Assuming your monitor is 3D capable, you can do this but you will only see a maximum of 30FPS, because of the two 30Hz images.
