The option to adjust the resolution, aspect ratio, and scaling of a connected sidecar display (like it was on Catalina/Big Sur) has simply not been added to the new Mac OS Ventura settings menu. Also as option to adjust any resolution to my MacBook Pro 16 screen. I want to choose resolution on my own, why Apple decided to give me just a few presets with icons and name it like: "More space"etc.
Which means that any connected Sidecar display will have top and bottom letterboxes. SideCar was the only reason to buy the iPad for my professional purposes and now i cannot use it!
