I'd check display_gamma and file_gamma.

If it's only display_gamma that is wrong, then you are OK as the 
effective output should be correct.

If file_gamma is wrong, then your images will have incorrect gamma 
information and will display incorectly.

A good bet would be to set both to sRGB as it should match most hardwares.
Keep assumed_gamma 1
