As a general guide: Quad HD or 1440p (2560×1440) is the same real estate as 720p, but at 2×; 4K (3840×2160) is like 1080p at 2×; 5K (5120×2880) is like 1440p at 2×; UHD is not consistent at all — divide the device’s resolution by two to get the real estate.
1080p actually needs 4K equulvant pixels for macOS, unless you want the blurry version
Because Apple products suck. You’ve been linked the relevant information on how apple’s bullshit marketing uses “Retina” to refer to everything, causing your confusion. Now I’m just gloating. Apple sucks.
Why is 4k@60hz capability necessary for 1080p@60hz?

Relevant part , under “Retina” section:

That’s so strange. I think I got really lucky with my €140 AOC monitor and my aliexpress adapter because I’m getting 1080p at 75hz.
