To implement screen mirroring on Windows, set the display mode to "Copy". The specific steps are: select "Copy these monitors" after entering "Display Settings"; you can also use the shortcut key Win P to select "Copy" mode. In addition, ensure that the hardware is connected normally, including tightening the wire, correct display signal source and the device supports mirroring function. If you encounter problems, you can check the settings entry, shortcut key usage and hardware status, and update the driver or restart the Explorer if necessary.

To implement screen mirroring on Windows, it is not complicated, and it is mainly to adjust the mode in the display settings. If you want to cast the computer screen to an external monitor, TV or projector, and want the same content to be displayed on both screens, use "Copy" mode instead of "Extended" mode.

How to enter the display settings

First, right-click the blank space on the desktop and select "Show Settings". Or you can press Win I to open the settings and click "System" → "Show".

Here you can see multiple monitors connected. You usually see two icons representing the home screen and the second screen. What you need to do at this time is:

• Click on a monitor icon to see its number and current settings
• Select Copy These Monitors from the Multi-Display drop-down menu

After this operation is completed, the same content will be displayed on both screens.

Quick switch with shortcuts

If you often need to switch the display mode, you can use shortcut keys to operate quickly.

Pressing Win P will pop up a sidebar with four options:

• Computer screen only : only displayed on the screen that comes with the laptop or host
• Copy : The same content is displayed on both screens (that is, mirroring)
• Extend : Expand the desktop to another screen to become a larger workspace
• Second screen only : Only display screen on external monitors

Just select "Copy" directly. This method is especially suitable for temporary switching before meetings and demonstrations.

Check if the hardware connection is normal

Sometimes even if "copy" is set, the screen still does not respond, which may be a problem with the wire or interface. For example, the HDMI, VGA, and DP interfaces have poor contact, or the monitor does not correctly identify the input source.

We suggest you check it out:

• Is the wire tightly inserted?
• Is there a correct signal source for the external monitor (such as HDMI 1 / HDMI 2)
• Whether mirror display is supported (very few old devices may have restrictions)

If everything is OK but Windows still can't detect the monitor, try updating the graphics card driver or restarting Explorer.

Basically that's it. It is not difficult to operate, but some details are easy to ignore, such as shortcut keys, display settings entry, hardware connection status, etc. When encountering problems, you can check them step by step, and most of the situations can be solved.
