I have a MB Pro M1, 14 inch, running the latest version of Ventura (13.2) and when using in clamshell mode, I cannot get the screensaver to activate or get the display go to sleep (external Dell Ultrasharp U3421WE).

In extended display mode, no issues, both built-in and external display go to sleep at the same time.
As for clamshell mode, I tried different settings, different time settings but the display just stays on all the time. Any suggestions ?
