as soon as you change the brightness/contrast/color in the panel of the x3100, it erases the previous settings of your icc profile
since i don't know if i'm understood:
try to modify the contrast via the intel panel, the color etc, clic apply, exit
then, go to the intel panel again, clic on the red, then on all, then press tab to reach the brightness area, and press the up key below the right shift key, the color goes back to the default mode, wich is really crappy
same thing with the displayprofile. exe where you can find that yhe tplcd.icm from the lenovo website don't change anything
example:
dl some icm here
http://dl.free.fr/qyk33Vqzl/icm.zip
unzip the display.zip and install the icm fils in the right file of windows, and make sur you go to right clic on desktop/properties/setting/advandced/color management and see the icm files
ok, then run displayprofile.exe, and you get all the icm files which are installed
ok , then clic on some of them, and your screen will change as soon as you click
allright now, you clic on tplcd then on a profile which is different of tplcd, tpflx and srgb, then on tplcd
so normally, you get a change in the color behavior on clic 1, but nothing on clic2 ie when you come back to tpcld
ok, i have to say i'm quite noob with color management /icc/ etc
but that my experience
