Projectors have their own native refresh rate --- which complicates the entire thing.

Sometimes monitors will convert what they receive to a common rate which works with the DLP chips.

Are you using a DLP projector?

(DL1's also dont like working at 75hz - when you strobe them fast (black/white ) - you will notice banding in the image - but for most content this is OK )
