[NAME]  Open Windows Display Settings. In the diagram at the top of the settings list, based on the description of your current setup you should see two tiles. One will show two numbers, such as “1 | 2” or “1 | 3”, to indicate that two physical displays are mirroring a single image, and then you’ll have a second diagram for your remaining, independent display. In that case, select the tile corresponding to the mirror setup, scroll down, and change the setting from Duplicate to Extend.
I have a Latitude 3500 (Windows 10 Pro 20H2), Dell Dock WD19, and 2 Dell monitors. One monitor and the laptop share the same image. Is there a way to display a different image on each screen so that I can work among 3 images? My coworker has a new Dell Inspiron 15 5000 with a different dock and he can split 3 ways. Thank you.
