…integer frame rate (eg: 59.977hz, 60fps), also adds the ability to toggle automatically changing the screen's hz to the video's frame rate with a script binding.

Glad you like the script. I don't really have the time to maintain it anymore, but I've done a quick code review.

This seems a little risky, the framerate of the video is also rounded down, because that is what nircmd expects. Rounding up here could cause comparison issues. Shouldn't this be solved by removing 60 from the list of valid rates in your config options? If the highest is 59 then it should detect that the display is already at this rate and not try to change anything.

Have you tested how this interacts with script-opt on_update changes to the auto option?

Hello, I am a fan of your changerefresh script for mpv, however, I had an issue where the video would pause despite the frame rate and the screen's Hz matching. I was initially confused by this as it seemed this issue had been solved in an issue.
Looking into it, the way that the code checks if the screen's Hz and FPS are the same does a floor rounding. This means that if the screen's Hz is slightly below the video's FPS or the screen's Hz that the FPS has been configured to change into, the video will still pause.
My laptop's screen's 60Hz mode is at 59.977Hz, which while using nircmd it rounds to 60, because the comparison in your script always rounds down, the video pauses. To solve this, I added 0.5 to the screen Hz in the comparison to simulate rounding to the nearest integer. (eg: 59.977Hz -> 59Hz, but 60.477Hz -> 60Hz) This solved the problem for me.
The second addition this PR adds is the ability to toggle the 'auto' option via script binding, which means that automatically changing the screen's Hz to the video's FPS can be enabled or disabled using a keybind.
This is useful as there are some videos where I do not want my screen's Hz to change automatically to its FPS, such as some mathematics videos that are sometimes encoded at 25 FPS or 30 FPS, where the motion smoothness does not matter. In addition, I watch the videos at a faster speed, so even if it changes the Hz to match the FPS, the video's FPS will not divide into the Hz evenly anyway.
I hope you can look over this soon and merge the changes so that others can benefit. Thanks again for the script.
