Pressing the Windows key plus P opens the Project sidebar on your primary monitor, not both screens simultaneously. This design ensures you can quickly switch between Duplicate, Extend, and other projection modes without visual clutter on secondary displays. If you are trying to see options on two screens at once, you need to understand that the OS treats the shortcut as a context menu for the active display environment rather than a mirrored interface element.
Understanding the Win+P Shortcut Behavior
The
Win + P combination is a system-level shortcut designed to toggle display modes rapidly. When activated, it generates a floating window known as the Project sidebar. This sidebar appears anchored to the top-right corner of your primary display. It does not replicate across extended monitors because doing so would create overlapping menus and confuse the user about which screen is being controlled. The operating system assumes you want to manage the projection mode from the main desktop view.
Why It Does Not Appear on Secondary Screens
Many users expect the menu to show up on every connected display. However, Windows 10 architecture restricts this UI element to the primary monitor. This prevents accidental clicks on secondary screens when you are working in an extended desktop setup. If you have multiple monitors arranged in a complex layout, the system still identifies one specific monitor as the primary output for such overlays. You cannot force this specific menu to render on all attached displays simultaneously through standard settings.
Configuring Display Modes via Settings
If you need more control over how your second screen behaves, you should use the native Display Settings panel. This method allows you to set permanent configurations that do not rely on temporary shortcuts. Navigate to
Settings >
System >
Display. Here you will see a diagram of your connected monitors labeled with numbers like
1 and
2. Click on the monitor representing your secondary screen to adjust its properties.
- Select Duplicate: This mirrors your primary screen exactly. Useful for presentations where both audiences need identical content.
- Select Extend: This creates a single large desktop space across both monitors. Ideal for productivity tasks.
- Show only on 2: Turns off the primary screen entirely. Best for connecting to a TV or projector while keeping your laptop closed.
After selecting your preferred mode, click
Apply Changes. The transition happens instantly. Your applications may shift positions depending on whether you chose duplicate or extend. You can rearrange the physical order of the monitors in this same window by dragging the numbered boxes left or right. This ensures mouse movement flows naturally between screens.
Managing Multiple Monitors Efficiently
Once your display mode is set, you might find yourself needing to access content across different screens regularly. For instance, referencing data on one screen while working on another is common. You can read more about accessing Monitor A's content from Monitor B in our guide

Additionally, if you are using a Thunderbolt dock or a high-bandwidth connection, you might encounter locking issues. Check out
Windows 10 Multi-Screen Lock Issues: Troubleshooting Guide if your screens behave unexpectedly after waking from sleep. These issues often stem from driver conflicts rather than the display mode itself.
Alternative Methods to Switch Modes
While
Win + P is the fastest way to toggle modes, it is not the only option. You can also use the Action Center. Click the notification icon in the bottom-right corner of the taskbar. Look for the
Project tile. If you do not see it, click
Expand to reveal more tiles. Clicking this tile performs the exact same function as pressing the keyboard shortcut. It opens the same Project sidebar on your primary monitor.
Some third-party utilities offer more granular control. Tools like DisplayFusion allow you to create custom hotkeys or automate display switching based on application focus. However, for most users, the built-in Windows features are sufficient and more stable. Avoid installing unnecessary drivers or bloatware that claims to enhance display functionality, as these often cause resolution glitches.
Troubleshooting Common Display Issues
If your second monitor remains black after pressing
Win + P, check your cable connections first. Ensure the HDMI, DisplayPort, or USB-C cable is firmly seated. Sometimes, simply unplugging and replugging the cable forces the system to re-detect the hardware. You can also try restarting the graphics driver by pressing
Ctrl + Shift + Win + B. This command resets the video subsystem without rebooting the computer.
If the resolution looks incorrect, go back to
Settings >
System >
Display. Select the problematic monitor and scroll down to
Display resolution. Choose the recommended setting, usually marked as
(Recommended) next to the value. Mismatched resolutions can sometimes make text appear blurry or windows too small to interact with properly.
Frequently Asked Questions
Can I make the Project sidebar appear on both monitors?
No, Windows does not support displaying the Project sidebar on multiple monitors simultaneously. The UI element is strictly tied to the primary display to prevent interface conflicts and ensure clear user input.
What is the difference between Duplicate and Extend modes?
Duplicate mode shows the exact same image on all screens, ideal for presentations. Extend mode treats each monitor as a separate part of a larger desktop, allowing you to drag windows between them freely.
How do I change which monitor is primary?
Open
Settings >
System >
Display. Click on the monitor you wish to make primary and check the box that says
Make this my main display. The taskbar and start menu will then move to that screen.
Why does my second monitor flicker when I press Win+P?
Flickering usually indicates a driver issue or a loose cable. Try updating your graphics drivers from the manufacturer's website. If the problem persists, test with a different cable to rule out hardware faults.
Is there a way to remember my last display configuration?
Windows generally remembers your last used configuration for each session. However, if you connect and disconnect devices frequently, you may need to manually reapply your preferred settings each time you plug in your secondary monitor.
