Sorry Chuck, I was wondering the same thing!
While talking about the Advanced menu, I see that the Contrast option that is shown in the manual, simply isn't there in my rig. Is it perhaps becuase the later models have an OLED screen?
Also changing the brightness setting down from 100% to 30% has no noticable affect on the screen brightmess - is anyone else seeing this as well or do I have a faulty rig/display?
