Screensaver slideshow does not display correctly whith dual monitors set to "extend desktop"

Objective: I have dual monitors (as an extended desktop, side by side) and want it to show my own pictures as a screensaver slideshow in Windows 10.

Problem: Only the lower half ot the picture is diplayes in the top half of monitor 1. Monitor 2 is black.

Addtional observations:

• In "Screen Saver Settings" the small mock-up display looks fine, however when i select "Preview" the problem with only half the picture displayed occurs also in the preview.
• The problem does not occur with only one monitor in use
• The problem does not occur with dual monitors set to "Duplicate these displays"

Gratefull for all suggestions to solve the problem

The same picture also work fine as desctop background with different pictures displayed on each monitor.

 

When "Duplicate these Displays" is selected, external monitor displays upside down, but not the Surface Pro screen

After Windows 10 updates were automatically installed last night, my LG external monitor displays upside down when "Duplicate these displays" is selected under Display settings. With other options (Extend these displays, or Show only on 1, or Show only
on 2) the external monitor shows the correct orientation. PC is Surface Pro 3 with Windows 10 Pro operating system. LG monitor is 34UM95-p 34" Ultrawide IPS Monitor. Ctrl-Alt-Up or -Down do not work. Drivers are up to date. Thanks in advance
for help/suggestions.

 

Force screensaver to specific monitor in multi-display environment

I have a total of 3 monitors; two are running 1920x1080 with the other at 3840x2160. I use screensaver at the lock screen to display photos. I am running Windows 10 Pro. While there have been hardware & software changes over the years the screensaver
configuration has been the same for years.

My question is this: How can I force screensaver to use a particular monitor?

In Win10 screensaver wants to display the photo across two monitors. I want it on the 4K monitor (only). I tried DisplayFusion and had success. This tells me it's possible. Is it possible without resorting to a third party application?
