I just upgraded to MacOS 12.2 (12.1) and my ultrawide monitor has lost many resolution options, both 'Retina' and not, in Parallels Toolbox Switch Resolution. It's the same monitor, same cable, same computer. Attached are screen shots of Parallels Toolbox Switch Resolution from MacOS 12.2 and 10.15.7 (Catalina) since that's the only way for me to go 'back' by using an older computer with the same monitor/cable.
How do I get these options back? Notably 3840x1620 as RETINA
