YES. The current shipping docks from CalDigit, such as, TS4, TS3 Plus, Element Hub, SOHO dock are compatible with “Stage Manager” on iPad. Please note that ONLY Apple Silicon iPads can support Stage Manager. Also you MUST connect both keyboard and mouse to the dock, or use Apple’s Magic Keyboard with Trackpad, before extended display can work through dock.

The “Arrangement” setting in “Display & Brightness” would only be available through dock when iPadOS detects both keyboard and mouse devices.
