In today’s digital world, many of us rely on laptops for both work and personal use. While laptops offer portability and convenience, their built-in screens can sometimes feel restrictive, especially when multitasking or engaging in visually demanding tasks. Connecting an external monitor can significantly enhance your productivity and viewing experience. However, a common issue arises: how do you display the content exclusively on the external monitor and turn off the laptop screen? This comprehensive guide will walk you through various methods to achieve this, covering different operating systems and troubleshooting common problems.
Understanding Display Modes
Before diving into the specific steps, it’s crucial to understand the different display modes available on your computer. These modes dictate how your display is distributed across your laptop screen and any connected external monitors. The most common modes are:
- Duplicate (Mirror): This mode mirrors the content from your laptop screen onto the external monitor, displaying the exact same image on both screens.
- Extend: This mode expands your desktop across both screens, treating them as a single, larger display. You can drag windows and applications seamlessly between the two screens.
- Show only on 1 (Primary): This mode displays content only on the primary display, which can be either your laptop screen or the external monitor.
- Show only on 2 (Secondary): This mode displays content only on the secondary display, which is typically the external monitor. The laptop screen will be turned off.
Our goal is to achieve the “Show only on 2” mode, allowing you to fully utilize your external monitor while conserving power and minimizing distractions on your laptop screen.

Why would I want to display only on my monitor and not my laptop screen?
Using only an external monitor can improve your productivity and comfort. By displaying your work on a larger screen, you can have more space for applications and reduce eye strain. It also allows you to maintain a better posture by positioning the monitor at an optimal height and distance, something often difficult to achieve with a laptop screen.
Another benefit is that it can extend the lifespan of your laptop screen and reduce power consumption. By turning off or disabling the laptop display, you’re minimizing wear and tear on the screen and saving battery life. This is particularly useful when using your laptop primarily as a desktop replacement.
How do I display only on my monitor on Windows?
Windows offers several methods to display only on your external monitor. The quickest way is to use the keyboard shortcut: Windows Key + P. This will bring up a projection menu where you can select “Second screen only” to display only on your connected monitor and turn off your laptop screen. You can also choose “PC screen only” to revert back to just your laptop screen.
Alternatively, you can access display settings through the Settings app. Go to Settings > System > Display. Under the “Multiple displays” section, you’ll find a dropdown menu with options like “Duplicate,” “Extend,” “Show only on 1,” and “Show only on 2.” Select “Show only on 2” to use only your external monitor. Make sure your external monitor is properly connected before doing so.
How do I display only on my monitor on macOS?
On macOS, mirroring or extending your display to the external monitor is the first step. Connect your external monitor and go to System Preferences > Displays. Look for the “Arrangement” tab. If the “Mirror Displays” checkbox is selected, uncheck it to use the monitors in extended mode.
To display only on the external monitor, you’ll need to close the laptop’s lid after connecting the external display. macOS should automatically switch the display to the external monitor. If it doesn’t, go to System Preferences > Battery > Power Adapter and ensure that “Prevent computer from sleeping automatically when the display is off” is unchecked. This allows the display to turn off when the lid is closed, while the system continues to run and display only on the external monitor.
What if my external monitor is not detected?
If your external monitor isn’t being detected, the first thing to check is the physical connection. Ensure the cable is securely plugged into both the laptop and the monitor. Try using a different cable to rule out a faulty cable. Also, ensure the monitor is powered on and set to the correct input source that corresponds to the connection you are using (e.g., HDMI, DisplayPort).
If the physical connection is confirmed and the issue persists, try restarting both your laptop and the monitor. After restarting, check for updated graphics drivers. Outdated or corrupted drivers can often prevent the system from properly detecting external displays. Visit the website of your laptop manufacturer or graphics card vendor to download and install the latest drivers.
Can I still use my laptop’s keyboard and trackpad when only the external monitor is active?
Yes, when using only the external monitor, your laptop’s keyboard and trackpad will still function as normal. The laptop essentially treats the external monitor as its primary display while the built-in display is disabled or turned off. All input devices connected to your laptop will continue to work seamlessly.
However, if you close your laptop lid, some laptops might enter sleep mode despite the external monitor being active. To prevent this, you may need to adjust power settings in your operating system to keep the laptop running when the lid is closed. This ensures continuous operation without interruption when using only the external display and the laptop’s built-in input devices.
Will displaying only on my monitor affect my laptop’s performance?
Displaying only on an external monitor generally has a minimal impact on laptop performance. In fact, it might even improve performance slightly in some cases. When the laptop screen is turned off, the graphics processing unit (GPU) has less work to do, potentially freeing up resources for other tasks.
However, the performance difference is often negligible unless you are running graphically intensive applications. The biggest performance bottlenecks typically stem from the CPU, RAM, and storage speed, rather than the display output. Therefore, displaying only on your monitor is unlikely to have a significant positive or negative impact on overall performance for most users.
Are there any special considerations for dual monitor setups beyond just the external monitor?
When setting up a dual-monitor configuration where your laptop screen is off and the external monitor is primary, consider the arrangement of the displays in your operating system’s display settings. Configuring the physical placement of the monitors accurately helps ensure a smooth experience when moving the mouse cursor between screens. This allows you to drag windows and applications seamlessly across both displays.
Additionally, pay attention to the refresh rates of both monitors. Mismatched refresh rates can sometimes cause visual stuttering or tearing, especially when dragging windows or playing videos. It’s best practice to set both monitors to the same refresh rate or to use the highest refresh rate supported by both displays for a smoother visual experience. This is typically done within your operating system’s display settings.
