This also exposes the reasoning for some of my decisions with Dippi; when first considering HiDPI at System76, we ended up using very similar logic to what Apple does for native DPI ranges on laptop and desktop computers. That's why Dippi infers the display type and changes the calculation as a result.
I’m also interested in this Samsung ViewFinity S9, as it’s more like my current Dell UltraSharp 27, but with a HiDPI resolution. According to Dippi, it is also “ideal for HiDPI.” Huzzah for reasonable decisions!

In case you were wondering, Dell’s newly-announced UltraSharp 32 6K display comes in at an “ideal for HiDPI” rating from Dippi!

This means it should deliver a reasonably-sized UI while also showing off the benefits of true, pixel-perfect integer-scaled HiDPI: 4× crisper text, UI, and images without the blurriness of fractional scaling.
