10.15.6 & DLManager on 2019MBP: screen saver
 

Hello there, I'm wondering if someone could point me in the right direction.

Running a 2019 MacBook Pro 15", 16GB of RAM. Am on 10.15.16, completely up to date. Running DisplayLink Manager 1.1. And I have this Mac plugged in to a Dell D3000 docking station, via a USB-C cable. I have two Dell 24" 2k monitors plugged in.

The screen saver, when activated after 5 minutes, shows only on my open MacBook Pro laptop screen. I use all 3 monitors. I can easily change wallpapers, but there are not options in System Preferences-->Screen Saver to tell my Mac when connected to the dock/two external monitors to show my screen saver (a folder of pictures in my ~/User/myacccount/Pictures folder) on all 3 monitors.

I have the screen saver set to shuffle pictures and show the clock. This works perfectly on my MBP monitor only. Nothing I have tried will offer me options to show the same screen saver/folder of pictures, shuffled, on all 3 monitors. I have the screensaver set to trigger after 5 minutes. I do not need to log in after pressing a key on the keyboard, all I have to do is Touch ID.

Where might I find options to add to System Preferences-->Screen Saver so that when connected to the Dell D3000 dock and running DisplayLink Manager, and the screen saver activates, the pictures show on all 3 screens/both external monitors instead of just the MBP screen (the two external monitors, while the SS plays on the MBP screen only, are blank).

Thank you for any advice.
