Thanks for clarifying Matt,
So are you saying that if I change my monitor output to 720p 25Hz (I'm in PAL land) that I should get a live update of what menu function I'm in, on the Small HD over HD-SDI?
I'm unsure if the Small HD will accept the 720p 25Hz signal, but if it does, you should have menus. Now if you have an LCD or EVF attached also, then you'll just have ui status (histograms/guides/current settings/etc) on hd-sdi.
