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).
