Five years ago, I got a 40-inch 4k@60Hz for under $400. I recently got a 43-inch 4k@60Hz for $450. The new one is lighter and somewhat more color accurate. I don't get the obsession with small pixels; my eyes prefer if I stand/sit a bit further from a bigger monitor, and it's great for pairing/teaching.

I spent a while with a 27" 4K monitor. It looked nice in HiDPI modes on my Mac, but I didn't get that much usable screen real estate (I was running it about 1440p). When the pandemic hit and I started working from home every day, I upgraded to a 43" 4k display. I now have the equivalent of 4x 21.5" 1080p displays, which is far more usable than 1x 1440p, even if it doesn't look quite as nice.
