This looks pretty good. Though scaling in browsers has been mostly independent of corresponding OS features for quite a while. E.g. the issues mentioned above with Linux and fractional scaling do not affect browsers as much. The problem is usually with native UI elements, such as the settings app itself.

However, it is unclear to me what are the scaling ratios relative to the native resolution in your examples. In this article for Sierra you seem to be only able to pick integer factors: https://www.eizoglobal.com/support/compatibility/dpi_scaling...

Maybe? But that's ancient history.

I don't know what the ratios are - the UI doesn't expose them.

What does it expose? In Sierra as you can see from the screenshot it simply shows scaled resolutions. So you can just divide native resolution by the scaled to get the factor.

It looks like it treats them as 0.5 / 0.67 / 0.78 / 0.87 / 1.0 scaling (1080 / 1440 / 1692 / 1890 / 2160 for physical resolution of 2160).

But this is all a bit arbitrary - I think the macOS API deals with an abstract 'points' unit.

Great to know. Might make me reconsider that M1 Mac Mini option.
