How do I set the gamma on my secondary monitor though software?

I am trying to set the gamma on my secondary monitor(That I pull out from my closet today,  It is nearly 10 years old.  The monitor is a HP vs17)  I did it on Windows though the calibration application it has. (https://www.youtube.com/watch?v=NsC51SvQTWQ at 2:24)  Someone in the IRC told me to run this command "xcalib -gc X.Y -a (Whatever value I want)"  But it output this command "Warning - Unable to get display calibration" and turns my monitor black other than the cursor until I restart it though GNOME's Color settings.  I try picking different profiles on both of them, it does nothing.

I have a Nvidia 745 4GB DDR3

Any ideas?

xgamma (xorg-xgamma)? or maybe an xorg conf. I am not sure how to set it for a specific monitor with them though (or whether it's possible at all).

nvidia-settings (~/.nvidia-settings-rc) can also do that, and apparently you can set per-monitor value with it:

can put `nvidia-settings -l` in .xinitrc to make the conf load whenever X is started.

I don't know I overlooked it in the Nvidia settings.  Thanks.
