Bounty: 50

I want to reduce the refresh rate of my secondary monitor to something really small, such that my GPU doesn’t has to do as much work.
But there is no option to change the refresh rate for my second monitor in the default "Displays" settings. It seems to be fixed at 60 Hz.

How can I throttle the refresh rate of my second monitor to only, let’s say 10 frames per second?… to free up some resources on my GPU.


Here is my display setup:

displays

I also couldn’t find an option in the NVIDIA X Server Settings:
