How are you getting moiré? Shooting a monitor with a camera? Looking at it through a window screen?
In general, moiré is the interference product between two patterns superimposed, and is especially evident when there is a slight difference in angle between the two patterns. You can reduce it by decreasing the detail in the patterns -- but then it also reduces the detail in the original picture. Unfortunately, this is not a new problem: in the printing world, making a halftone of a photograph can create moiré if there's a tight pattern in the photo.
If you're trying to get computer display into a video form, probably the best approach is to use a scan converter rather than a camera; if you just need a still, most computers let you take a screen shot.
