Ask HN: Where have all the large monitors gone?

Back in about 2016, I bought a 4K 40" display from one of those no-name South Korean brands on ebay (the AMH A399U), for just under $500. Great monitor, served me well for years, couldn't bring it with me in my last move.

Fast forward to 2024, and I'd like a replacement (and ideally after a decade there'd be an option with a higher-than-60Hz refresh rate, and/or higher-than-300nits brightness). On doing some research there is... very little like that on the market.

4K displays have all shrunk to 32 inches (or even 27), which I find too small for a large desk setup. All the >32 inch displays are in weird widescreen aspect ratios, and most of them sacrifice significant vertical resolution. Or one can go up to 43"+, where all the panels seem to be repruposed TVs, many of them with text rendering issues (no 4:4:4 chroma), and/or OLEDs with text rendering issues + burn-in risk, which makes them kind of suspect for coding work.

Is there any surviving (even off-brand) source of 38"+ 4K displays in a standard 16:9 aspect ratio?
