A simple Win10 actualization may changed it?<br />
<br />
Amazingly another laptop had an actualization yesterday and no video troubles...<br />
The combo &quot;Multiple Displays&quot; remains on it.

Check your display (and monitor if you have them) drivers, just in case Microsoft have helpfully replaced one at the same time.

<div>
Have you checked Device Manager to confirm how many monitors Windows is seeing?

After another reboot things subtly start working...<br />
And the option reapeared.<br />

This topic area includes legacy versions of Windows prior to Windows 2000: Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions including Windows Mobile.

Windows OS

A monitor or a display is an electronic visual display for computers, usually comprised of the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors used a cathode ray tube (CRT) about as deep as the screen size. They are connected to the computer via VGA, DVI, DisplayPort, Thunderbolt, LVDS or other proprietary connectors and signals.
