Yes, that's correct. I was setting up and testing vectorworks to get that laptop ready for another employee. I erased the hard disk and did a clean install of 14.4.1 and then downloaded a new copy of vectorworks. I realize now that I did all of that testing while not hooked up to an external display. That said, the recipient of the M2Max laptop has been using it for several days, with an external display, and has reported no issues.
Also, in case it's relevant, I use a thunderbolt connection to my external monitor. That was the case for the M2 Max and the new M3 Max laptop.
