When I use the brightness changing buttons Unity changes the brightness by two levels each time to create a nice effect. However, I only have about 10 different brightness settings and so this effect has caused a reduction in brightness settings to 5. I change my brightness regularly to suit the lighting in the room I'm in, but am unable to do this so effectively now that the number of levels has been reduced. Is there any way of turning off this brightness effect and controlling my brightness setting more sensitively? Thank you for your time. EDIT: It may not be 2 levels it changes at a time but 3, I've worked this out as the brightness control panel allows you to set the brightness accurately and there seem to be a couple of settings that the button misses completely when I change the brightness with the buttons.
