Adjusting The Viewfinder - Canon PowerShot SX40 HS User Manual

Screen Display in Low Light Conditions
The display automatically brightens when shooting in low light conditions,
allowing you to check the composition (Night Display function). However, the
brightness of the image on the screen, and the brightness of the actual image
recorded may be different. Screen noise may appear and the movement of
the subject may appear somewhat rough on the screen. This has no effect on
the recorded image.
Overexposure Warning during Playback
In Detailed Information Display (p. 40), overexposed areas of the image flash
on the screen.
