UD-3900pdz MacBook Pro 2 -3 screen

Working with driver installed but when dragging open windows the window only displays on one screen at a time I cannot use an open across 2 monitors. Is there a setting to enable this?

Hi Phil,

Thanks for contacting us, I am happy to help!

macOS disables windows spanning multiple displays by default, we can change this to allow windows to be stretched across multiple displays by performing the following:

  1. Open the Apple Menu > System Preferences > Mission Control
  2. Uncheck the “Displays have separate Spaces” checkbox
  3. Log out of the user account
  4. Log back in

This should allow you to stretch a window across multiple displays.

Please let me know if this helps, or if there is anything else I can do to help, and have a great day!
