120Hz @ 30fps / 60Hz @ 30fps

No, it still looks like 30fps. But the refresh rate of that monitor is faster.

Doesn't that make the 30fps look like 60fps, since it flickers the screen four times, instead of the current two (60Hz)?

I don't know how else to explain my view, but I try:
30fps*4x = 120Hz / 2 = 60fps (FRAPS still says 30fps of course)
