I think you should drop  xgamma and reset your monitor. There is so
much confusing around the net on this topic, so I understand your
confusion.. Calibrating a lcd in  the budget class, are quite simple.
 I have a similar monitor myself. I have done the following with my
settings. On the monitor OSD find the reset color menu item. It means
that the contrast is set to factory default 50%. The color control are
also rest, the only thing I changed is the brightness. You have to
adjust this when you are inside dispcal. It's option 3 white level.
Skip all the other option except 6.
That's all.


Load the profile with dispwin.
$dispwin –S myprofile.icc
And
$dispwin –L

I'm pretty sure you will see a differences. And you have of course to
use a program that handles icc profiles well.  After you are familiar
with this method, try  the longer version with dispcal-targen-dispread
described in the documentation. You may also try with the L* star
gamma (–gl) option to dispcal.
