Currently, I am still working Ventura 13.7.8 on a M1. (Upgrading to a more recent OS is not currently an option). When I startup the system the screens will ONLY appear IF I launch the Displaylink after startup. They flash on for a moment, then a box appears "no signal", then black. Once I open up Displaylink, they will flicker back and forth, left, right then eventually settle. Is there any means for the two screens to appear without this additional prompting at start up? Appreciate any helpful feedback.
