Auto Refresh Rate Changer Worker

A Service Worker to change the refresh rate of your monitor when changing between power schemes regardless of the AC power state.

Why?

Well, in my country we have constant power outages, so during a power outage, my laptop (with a 144hz monitor) would be running on an external battery.

Most OEMs provide this functionality with their laptops, but the trigger would be the loss of AC power which isn't what I want since technically even during a power outage I am still on AC power.

So this worker switches the refresh rate on the basis of the chosen power scheme rather than the detection of AC power.

How?

Most of the code is done using PInvoke to detect the active scheme, detect video mode, and set the new frequency when necessary.

The worker uses the appsettings.json config file (which should be filled by you) to get what are the power schemes that you consider high performance and what frequency limits you would like to switch between (If your monitor supports them).

Todo

• Let the worker get the highest and the lowest refresh rates and switch between them.
• Let the user set the limits in the config file.
• Maybe find a way to get the family of a scheme automatically? like: Power saver High performance Balanced.
