I bought a Dell Inspiron (which runs Windows 7) and they seem to have done something to the brightness controls because it seems to be more coarse than I remember from my previous HP Pavilion (EDIT: yep. I can only change the brightness in jumps of 6). I wish to get a better control of the screen brightness to tune it to the specific sweet spot I'm interested in.
The model is N5110. Is there a program or setting that can do this for me?
