I've had the problem that the fullscreen mode is considerable brighter than the windowed one. You can check this by alt-entering between the modes or by alt-tabbing to the desktop, which then becomes too bright too.
You can fix this permanently by opening the console with shift+tilde and type "r_overBrightBits 0".
