Depend on your monitor and video card (some have correction for gamma, 
which may worsen thing if applied in the wrong direction!).

My office monitor is far more than gamma 3 ! (in fact the red, green and 
blue gamma are not identical for it, but I use the correction from the 
video card, which allow to split the gamma setting, to get a single 
value for povray.)

Best check so far I have found is to render the povray portfolio, on the 
  stone1.inc third html page (3 of 14), you should look at T_Grnt15 and 
T_Grnt17. If povray & your computer gamma are not correctly set, you 
will only see black images. Whereas, once correctly tunned, T_Grnt15 is 
pattern of dark black and lighter purplish strock of grey, and T_Grnt17 
is a mix of dark yellow, green and blue (both skyblue and navyblue).
