darkfix -free gamma display adjustment

Do you need a "free" tool to make gamma adjustments to any display you own and you are to busy to google for it?

For example gamma, brightness and contrast adjustments to old thinkpads like a 600X?
And you don't want to invest any money for it; e. g. in a program like power strip?

Or do you have a graphics card from nvidia or radeon where you can't "fine" adjust the screen with the latest drivers?

Than I would download the tool "darkfix" from this page: http://www.ben-huebner.de/.

A great tool which you won't regret downloading.

Thanks for your interest.
