People seem to make a big stink about having a "true" 120Hz display. You're suggesting that those displays only work at 120Hz if they use HDMI 1.4b, D-DVI, or DisplayPort, correct?
Those screens do, in fact, refresh upwards to 600 frames per second if they are rated for it. The display can do it, the input does not. By my understanding, and I'm unsure on this part, but VGA is suppose to support above 60 hz at 1080p, and I wouldn't be surprised that if you hooked up your 120 hz display via VGA that you'll be able to input more then 60 hz signals. Can anyone confirm that?
If the signal input is only sending a 60 hz signal, then the maximum output refresh rate is 60 fps. The display is a different story. After that, you need to consider the individual pixel transition rates as well. So even if your monitor is 60 hz, colour shifts may not be operating at those rates either. 5ms response times can have, for example, a blue LED shifting to a green LED in 17ms, which then implies that the display output is not exactly 60 fps.
But anyways, yes, you need a cable to support enough bandwidth to have the input to the display operating at above 60 hz if you want to output more then 60 viewable frames per second.
