The Display-Off sensor under the viewfinder eyepiece senses when you have brought the camera to your eye (or when another object approaches the viewfinder) and turns off the Shooting Settings display on the LCD. If you’d like to cancel this behavior and have the LCD display visible at all times (unless you turn it off manually by pressing the DISP. button), use this menu option. Selecting Enable activates the auto-off feature. Disable turns it off.
