First, on IRC channel I have already solved some problems regarding the configuration of Digital Vibrance, with the help of Demm!
But because of irc, my English does not help me much, and slows down the discussion and solution of problems, I prefer to write about here, in more detail, with the help of google translate, which I hope do a good job!
As I said the first problem has been solved now are two more!
But first I want to see if the problem to me, because of my hacking to try to solve the first problem or if the problem is everyone!
This can be easily verified, because I think that many use the nvidia proprietary driver!
So first, these are the details of my card and my driver:
inxi -G
Graphics: Card: NVIDIA GK107 [GeForce GTX 650]
Display Server: X.Org 1.19.3 drivers: nvidia (unloaded: modesetting,vesa)
Resolution: 1680x1050@59.95hz
GLX Renderer: GeForce GTX 650/PCIe/SSE2 GLX Version: 4.5.0 NVIDIA 378.13
The first problem concerns the parameter "color correction"
I usually imposed the Brightness item to -5 or -10! Here I do not know why I just can not move anything, the scrool bar to configure the real parameters remains locked Beware of the "Warning" message!

The second problem relates to a new nvidia-settings setting that I discovered thanks to this article
https://kver.wordpress.com/2017/03/29/tearing-with-nvidia-proprietary-drivers-on-plasma-try-this/
That serves to solve the problem of Tearing (The tearing is the problem that while watching some videos sometimes appear annoying horizontal stripes) in the video, with nvidia proprietary driver!
I follow the imposed driving and save the settings, but when you restart your computer the "Force Composition Pipeline" setting is disabled again and again!
