My Nvidia settings won't stay set

[PoorOldSpike]

It's not a big deal but whenever I start my computer to play any game or sim (including DCS), I find that my Nvidia contrast/brightness/gamma settings have all gone back to my computer's default Win 10 graphics settings, and I have to re-set them again with Nvidia.

How can I make the Nvidia settings stay permanent?

Which settings are those? I thought the ones in the control panel only applied to video.
