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
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.
