Then your computer is wasting power by generating frames that the monitor simply cannot display.
I believe, and please feel free to correct me, that the refresh rate is the amount of times the monitor is refreshed in a second. This is essentially what a FPS measure is. So if you set your monitor to 75hz, it will refresh its image 75 times in a second.
Now vertical sync is an option that works with your monitor refresh rate. Most people shut off vertical sync because they get ridiculous framerates. Some people can get like 140 in UT2004 and such with vertical sync off.
But please don't be stupid like this. Vertical sync should indeed be on. It caps your FPS to your monitor refresh rate. So if you run a refresh rate of 60hz, then you will not get a higher FPS than 60.
Now why is this good you ask? Well it is pointless for your hardware to process more than 60 frames if your eye can't even detect it and your monitor can't even handle it. In a way you are giving your hardware a break by putting on vertical sync.
