Nvidia: output dynamic range? [SOLVED]

On Windows, in the Nvidia control panel, there is a setting under "change resolution" where you can set the output dynamic range, which for me was defaulted to "Limited". This means the black levels would only be between 7-253, rather than the full 1-255. I changed it to "Full", and got much better black levels. Does anyone know what the default behavior is on Linux, and if it's possibly limited, how that could be changed?

EDIT: It's found here in nvidia-settings: http://imgur.com/PxBqn5L

Re: Nvidia: output dynamic range? [SOLVED]

The drivers come with a GUI tool "nvidia-settings". The setting is hidden somewhere in there. You can change between full and limited range manually with that tool. You then afterwards have to change your desktop's config so that this here is run at some point at log in:

nvidia-settings --load-config-only

You can also change this in an X config file without using that nvidia-settings tool. The NVIDIA drivers come with a lot of documentation. You access it with this URL:

file:///usr/share/doc/nvidia/html/index.html

The chapter "Appendix B. X Config Options" mentions an option "ColorRange" that is doing what you want.
