50hz

No.The question is, why can't I?
As it turns out the Barcos I am using prefer multiples of 30Hz, so I am barking up the wrong tree anyway by wanting to change the frequency to 50Hz. Never mind.

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 )

If you change to 60Hz/30fps, please note there is a bug in the OS which requires the installation of the ATI displays software, and the manual setting of a 'performance setting'

you cant really switch to 60hz can you?
all your content would speed up?

and you are using hidef stuff, so the performance probably wouldnt be enough?
