Companies besides Apple and LG have finally started releasing affordable retina-scale displays. I'm collecting them here mostly for my own notes.
A proper retina-scale external display for a Mac must have a pixel density of at least 200ppi. That means a 5K monitor should be 27" diagonal. 4K 27" monitors are disqualified.
Someone on the MacRumors forum made a comprehensive, less-up-to-date table, which might be worth looking at to see if I missed anything.
- Apple Studio Display: 5K, $1600
- ASUS ProArt Display 5K PA27JCV: 5K, $800
- Kuycon G27-X: 5K, $1000
- Dell UltraSharp 32 6K U3224KB: 6K, $2330
- Samsung Viewfinity S9: 5K, $1600
