Plugable's Silicon Motion guidance explains that its USB-connected displays are handled by Silicon Motion software. They are not equivalent to monitors wired directly to Intel, NVIDIA, or AMD graphics outputs. This can limit which vendor-specific tools and features appear for a dock-connected screen.

Arrange the workspace and choose duplicate or extended mode through Windows Display Settings instead. Available resolution and refresh options can be changed there. If a monitor is absent from Windows as well, record the dock model and physical connection for support; that is a different issue from a screen simply missing in a native GPU utility.
