    Dual monitors - extend works, duplicate does not.


    I have a Windows 10 PC, with two displays, a 1080p Lenovo monitor and a Samsung UHD TV. In settings, when I set the monitor to Monitor 1 (Samsung), the display is fine. When I set the monitor to Monitor 2 (Lenovo), the display is fine. When I set displays to Extend, both displays are fine. But when I set displays to Duplicate, both displays are distorted. The desktop, windows, text, icons, etc are stretched, with more horizontal stretch than vertical stretch, and the system is unusable.


    It is now Monday July 29; duplicate displays was working perfectly just last Thursday, July 25, 2019.


    How can I get "duplicate displays" to behave?

    :)

    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.
