I suppose I’ll dispute that. I don’t have a strong connection to 4k, but vs a 1080p computer monitor at less than 3 feet (since this is a computer monitor), 4k likely is visibly sharper. Now 4k on a 32 inch TV screen (with the increased distances people sit from the TV), and yeah, that doesn’t make much sense. But when it’s right in front of your face (as it would be on most desks), it probably does make a difference.
I see both points 🙂 I was referring to the fact that this is a monitor, not a TV, and if you want to maintain proper @2x upscaling of the macOS UI, 4K on 32" will make elements very big, defeating the purpose of a large display. To avoid that, you have to upscale things imperfectly, which will make the UI blurry and far from the crispness of Apple's iMac, Studio Display, and Pro Display XDR.It's a TV. Hence 2160 lines (1080x2).
Apple properly upscales legacy resolutions by 2x, optimizing for each specific display size:
- iMac 24" — 4.5K
- Studio Display 27" — 5K
- Pro Display XDR 32" — 6K
