Through the graphic card for the projector? For example 61hz?
Of the camera fps rate?
I am not talking about regular f-stop or shutter speed, but very fine adjustments.
In David live view, when setting up calibration, zoom in (mouse wheel). Is there any flickering, lines going across the screen, etc... or do you have a rock solid image? You must have the most stable image in live view before you start scanning.

What he means is monitor refresh rate. Some gfx cards have fine adjustment for this option. You can set refresh rate to 59 Hz, 60 Hz or sometimes even in between.

I was able to drastically reduce and almost remove the waves by changing the resolution of the camera. I was afraid that it would cause a loss of detail but that didnt prove to be the case.
Since the waves look more like a moire pattern, I think it has to do with the relationship between the projector's resolution and that of the camera. The solution could be making the camera higher, depending on your projector's resolution
