It maybe possible to improve the colour aswell (rather than just letting the current defaults take care of it. Do either of the following combinations of parmeters improve the colours aswell?
(You need to install the 'xvattr' package (from universe) to be able to send these commands to the video driver):
xvattr -a XV_BRIGHTNESS -v 0
xvattr -a XV_CONTRAST -v 48
xvattr -a XV_GAMMA0 -v 0x000000
xvattr -a XV_GAMMA1 -v 0x101010
xvattr -a XV_GAMMA2 -v 0x202020
xvattr -a XV_GAMMA3 -v 0x404040
xvattr -a XV_GAMMA4 -v 0x808080
xvattr -a XV_GAMMA5 -v 0xffffff
xvattr -a XV_BRIGHTNESS -v 0
xvattr -a XV_CONTRAST -v 48
xvattr -a XV_GAMMA0 -v 0x070707
xvattr -a XV_GAMMA1 -v 0x0f0f0f
xvattr -a XV_GAMMA2 -v 0x1f1f1f
xvattr -a XV_GAMMA3 -v 0x3f3f3f
xvattr -a XV_GAMMA4 -v 0x7f7f7f
xvattr -a XV_GAMMA5 -v 0xfefefe
They are bascially RGB-triplets which appear to be on a curve with 1-bit per gamma-value, but /not quite/...
