Multiple Displays

While laptops and other PCs are typically used with a single display, Windows 11 supports multiple displays. In these configurations, the built-in laptop display or first external display connected to a desktop PC is referred to as the primary display, while any other displays, including wireless displays, are known as secondary displays, and each can be configured in unique ways. Whatever the setup, each PC has a single primary display, while the number of secondary displays is limited only by its expansion capabilities.

Understand multi-display setups
Depending on the hardware, you can connect one or more secondary displays to a PC, configure each in Windows 11, and use them all together in different ways. Most people with multiple display setups use two displays, but the system works similarly with three or more displays as well.

How you connect a secondary display to your PC will vary from PC to PC.

The simplest multiple display configuration, perhaps, is to connect a portable display to a laptop via USB-C. But many laptop users will also create a desktop setup with a USB-C or Thunderbolt dock or hub, one or more secondary displays, and additional peripherals like a keyboard, mouse, and webcam. In this configuration, the secondary displays can be connected directly to the laptop via USB-C, or it they can connect to the dock or hub using USB-C, HDMI, or DisplayPort connectivity.

Desktop computers typically offer more expansion capabilities than laptops, and they can include a dedicated video card that has its own display connections. USB-C is common on desktop PCs, of course, but HDMI and DisplayPort connections are more common on desktop PC configurations with one or more secondary displays.

PCs of all kinds can also connect wirelessly to compatible displays using a technology called Miracast. And you can even use one PC's display as a wireless display for another PC; this is typically done with laptops, which have a built-in display.

And you can, of course, mix and match as needed. You can have wired secondary displays using USB-C, HDMI, or DisplayPort connections and one or more wireless displays, all connected to the same PC simultaneously if needed.
Connect to a secondary display
When you connect a secondary display to your PC--directly with a USB-C, HDMI, or DisplayPort cable, indirectly through a hub or dock, or wirelessly--Windows 11 will recognize the new device, trill a notification sound, display a pulsing on-screen pulse animation to indicate its success, and make it available for you to use.
Tip: Windows 11 uses built-in class drivers to make this initial connection, but in some cases you can obtain better drivers and related utilities via Windows Update or the display maker's website...
