OK, I am enountering a very odd problem.
I have a 30" Cinema HD Display that connects to a Mac via an Apple Dual DVI adapter which has Thunderbolt 2 and USB. (It needs both connections.)
1) This display functions perfectly with a 2015 MacBook Pro. (No adapters needed).
2) This display functions perfectly with a 2018 Mac mini, using a Thunderbolt C - Thunderbolt 2 adapter. USB connects directly to the computer.
With 2021 MacBook Pro 2021.... can't see this monitor. Display panel doesn't show Arrangement tabs.
Any suggestions?
