Extended Display Resolution

I have been running an LG 27UL600-W with my 2020 Macbook M1 Pro. I bought both items together and LG was always displaying at 3840x2160. Ever since I updated to Ventura 13.1 my resolution shows 1920x1080 as the native resolution. What happened? How do I get this to display correctly?

it may be that nothing has changed except that Ventura has decided to use its own unique terminology.


It appears that Ventura replaced the previous (admittedly confusing) way of describing screen resolution with a DIFFERENT confusing way of describing screen resolution.

... will provide the correct actual resolution, used for GRAPHICS.

TEXT at higher than 2K resolution is Scaled, and the way of describing that Scaling is what has created all these different confusing references.


Please let us know what is reported for your display. Mine is at 2K [so NO scaling] and Big Sur reports:
