Basically operating at standard pre-Retina Mac DPI levels. The 27" Apple Cinema Display had exactly this resolution, as well as the 27" iMac before it went to 5K.

I agree, it works… fine. But sadly more and more elements of modern macOS will look blurry / aliased because they are only made with hi-DPI in mind.

For example all SF Symbols, as far as I know, are not defined as pixel graphics but only stored as vectors and rasterized on the fly. Which works great at high res and makes them freely scalable, but on low-DPI displays they certainly look worse than a pixel-perfect icon would.
