Except... (there's always those damn exceptions!) it can't be strictly a
matter of your monitor, because I have a dual boot PC with Linux & Windows,
yet I cannot get the two to agree on display_gamma, even though its the
same hardware. With both set the same, what looks good in Linux will be too
dark in Windows.

And 2.2 is out of the question! If I set my display_gamma to 2.2, it doesn't
look right on anything else, and every scene I've ever rendered comes out
dark and oversaturated.
