Default Fixed 3rd display not working

Hi everyone. I've just been setting up a Dell Latitude 7490 with a Dell D6000 universal dock. It was behaving exactly as others have suggested. Only two of the 3 external monitors would display, in any combination. The only way I could get all 3 monitors to display was to set one of the external monitors as the main display (I used the HDMI), then disabled the laptop display by closing it. The third monitor didn't immediately display, but when I restarted the laptop (leaving the screen closed), and disconnected and reconnected the 3rd external screen to the dock, all three external screens finally worked, and I was able to adjust the resolution and arrangement, etc. as per usual.
