I'm running my dell 19"fp at 75hz, although, I think there's a lack of information about most of the marketing terms used to discribe the pixel "response time" in MS, if a monitor has 4ms gray to gray? what does that mean? if it takes an lcd 4ms to respond to a refresh at gray to gray, what's the time for the black to white? and how does the refresh rate effect the response time? Are there strange effects created in the display colors caused by a pixel site changing color between refresh hz? I'm sure it can only add to the time it takes to respond.. Inquiring minds want to know!
