MacBook Air M1 2020 no longer remembers External Display Settings on Ventura 13.1

I've had my MacBook Air M1 2020 for a couple of years now, have always paired them with external monitors of various types via a USB-C hub, and have never had any problems.

For the past couple of months (starting with MacOS Ventura 13.0.1), the Displays settings reset every time I connect my USB-C hub / external monitor. I have to manually change my native screen display setting to "More Space," and have to 1) Arrange my external monitor to the correct location and 2) manually set my external monitor resolution to 3440 x 1440 because for whatever reason MacOS does not have that set as a default resolution for my LG HDR WQHD.

This used to not happen, and it takes a couple of minutes every time, which becomes annoying given that I connect and disconnect from my primary workstation several times a day.

Can someone recommend a fix? Thanks.

Current configuration: MacBook Air Apple M1 16GB Ventura 13.1 Ext monitor: LG HDR WQHD.

MacBook Pro 13″

Hello michaelmiraflor,

To help resolve this issue, Update to the latest macOS. Apple's updates can contain software that is crucial to the operation of your Mac: Update macOS on Mac - Apple Support

Use Software Update

Before following these steps, it's a good idea to back up your Mac.

1. From the Apple menu  in the corner of your screen, choose System Settings or System Preferences.

• If you chose System Settings, click General on the left side of the window. Then click Software Update on the right.

• If you chose System Preferences, click Software Update in the window.

2. Software Update then checks for new software.

• If Software Update finds new software, click the button to install it. The button might be named Update Now, Upgrade Now, Install Now, or Restart Now, for example. You might then be asked to enter your administrator password.

• If Software Update says that your Mac is up to date, then no new software is currently available for your Mac model. Software Update shows only software that is compatible with your Mac.

You can also try connecting the display to the Mac using a different port or cable to see if the issue persists.

Best Regards.
