Bit of a random rant, but despite being so common, 27” at 4K is a really poor combination for a computer monitor. At 1x scaling, everything is too small, but at 2x scaling it’s far too big. So you have to go for a non-integer scale, which on macOS at least results in reduced image quality and graphics performance (it renders to a different sized frame buffer and then scales it).

The ideal is 5K, which is double 2560x1440 in each dimension, but essentially the only 5K displays available are the LG one made in partnership with Apple, which is over a grand and has numerous quality issues, or the one built into the iMac. It’s really annoying.

Are these documented anywhere? I have one (it's glorious) and I've not had a problem with it, but it'd be interesting to see the list.

I’ve seen lots of reports of interference with WiFi and/or Bluetooth on the older models (I believe since fixed). Recent models have lots of reports of bad backlight uniformity: https://forums.macrumors.com/threads/lg-5k-ultrafine-27md5kl...

Interesting, thank you!
