To be fair, the new Apple displays use the same panel so much of this still applies.

The first sentence doesn’t: “ Since writing about Mac external displays in 2016, not much has changed.”

Quite a few Mac-oriented 5K and 6K displays have been released in the last few years. LG, Asus, Dell, Samsung, Benq, Viewsonic. Maybe some others as well.

Do they? The new Apple monitor supports 120 Hz.

The price however, isn't indicative of a 2022 product...
