2024 is going to be the year of OLED monitors. Unfortunately no one is making a 4k 27" OLED which would be a pretty good all in one monitor. Plenty of 32" 4k available but not a huge fan of the Mac scaled option on those.

@paul Dough's Spectrum Black comes in 27 inch. The Spectrum One was really nice so I'd expect the OLED model to be nice too.
@HilliTech @paul Fwiw, as an owner of a (non-OLED) Spectrum monitor, I don’t think I’d ever recommend the company’s products. Among other issues, the firmware is just an unfinished mess, years after release. Too many bugs and rough edges for something I interact with every day.
@joshapos @paul I'm talking about the current product iteration with gorilla glass. I heard there were issues and refunds in the past when they were Eve, but they got rid of the problem distributors and reorganized. My experience has been pretty good.
