I'd hate to see that one needs to wipe out the system just to make DisplayLink work.
I remembered an additional thing I did the night before based on a reddit discussion (
https://www.reddit.com/r/MacOSBeta/c...eaks_external/)
So, before wiping out your system, you might try doing this, and then repeat the steps I listed earlier.
Open Terminal, and delete the below file with the "rm" command:
~/Library/Preferences/ByHost/com.apple.windowserver.displays.<LONG HEX STRING>.plist
Then repeat the steps I suggested earlier? Not sure if it will work, but perhaps

For what it is worth.
Revised steps are:
- Open Terminal, delete the file ~/Library/Preferences/ByHost/com.apple.windowserver.displays.<LONG HEX STRING>.plist
- Disconnect your DisplayLink usb device (hub) from the Mac
- Uninstall DisplayLink using the uninstaller. (macOS App LoginExtension-EXE.dmg)
- In system Settings/Displays, turn off True Tone, turn off automatic brightness adjustment.
- From App Store, search for MacOS Ventura, and reinstall system.
- After installation is complete, reinstall DisplayLink Manager. (DisplayLink Manager Graphics Connectivity1.8.1-EXE.pkg)
- Reinstall "Login Screen Extension" using macOS App LoginExtension-EXE.dmg
- Reconnect your DisplayLink device/hub. It will prompt the login screen again.
