is in relation to frequency. The frequency output of a video card must match the frequency set by the monitor or visa-versa. The higher the frequency the faster the screen re-paints itself. Most video cards can handle a range of frequency. Out of phase means that you have exceeded this range on one end or the other. Here is a link to further explain.

Whew!!! That's a long one.
and life goes on...
I posted a few weeks ago about hooking up a LCD monitor as a second display to my notebook, but the LCD would always be shakey and fuzzy looking. No solution was found to the problem after trying a few suggestions. I was messing around with the settings on the monitor and found a Phase setting that can have values from 0 to 63. I was able to increase or decrease the values until the display was perfectly clear again, no more fuzziness or shakiness; however, the problem would return later after an hour or so, and I'd adjust the phase setting until the display was back to clear. What is this phase setting? I have noticed no pattern in the values I chose to make my display clear again. I just increase or decrease the value until the display clears up. Does anyone have a less temporary fix to my problem? Thanks!
