A lack of display adjustment application and dissatisfaction with colour rendition, led me to find a commandline application for gamma adjustment.

xgamma -gamma g.g     where g.g is a value between about 0.2 and 2.0

Individual rgb settings can also be changed:

    -rgamma g.g             Red Gamma Value
    -ggamma g.g            Green Gamma Value
    -bgamma g.g            Blue Gamma Value
