Having a broken laptop screen can be incredibly frustrating. Whether it’s a cracked display from an accidental drop or a malfunctioning backlight that renders the screen unreadable, a damaged screen severely limits your laptop’s functionality. But don’t despair! You can still use your laptop by connecting it to an external monitor. This article will guide you through the process, covering everything from identifying the problem to setting up your external display for optimal use.
Diagnosing the Broken Screen
Before diving into the connection process, it’s crucial to understand the extent of the damage. Is the screen completely black, showing distorted images, or simply cracked? The nature of the damage might affect the steps you need to take.
A completely black screen could indicate a problem with the backlight, the screen itself, or the graphics card. Distorted images suggest a problem with the screen’s internal components or the graphics card. A cracked screen is a clear indication of physical damage.
If your laptop’s screen is cracked but still partially functional, exercise extreme caution. The broken glass can be sharp and potentially dangerous. Avoid touching the damaged area directly.
In some cases, the problem might not be the screen itself, but rather a software glitch or a driver issue. Try restarting your laptop. If that doesn’t work, try booting into safe mode to see if the problem persists. Safe mode loads only essential drivers and services, which can help you determine if the issue is software-related.
If you’re comfortable working with hardware, you could attempt to diagnose the problem further by connecting the laptop to an external monitor. If the external monitor displays properly, the issue likely lies with the laptop’s screen or its connection. If the external monitor shows the same distorted images or remains black, the problem could be with the graphics card.
Always disconnect the power adapter and remove the battery before attempting any hardware troubleshooting. This will prevent accidental electric shock and potential damage to your laptop.
Gathering the Necessary Equipment
To connect your broken laptop screen to an external monitor, you’ll need a few essential items. These include:
- An external monitor
- The appropriate cable for connecting your laptop to the monitor (HDMI, VGA, DisplayPort, or USB-C)
- Potentially an adapter if your laptop and monitor have different port types.
- A power source for your laptop and monitor.
The type of cable you need will depend on the ports available on both your laptop and your external monitor. HDMI is the most common and versatile option, offering both video and audio transmission. VGA is an older analog standard that transmits only video. DisplayPort is a digital interface similar to HDMI but is often found on higher-end monitors and graphics cards. USB-C is a newer standard that can transmit video, audio, and data, and can also be used for power delivery.
If your laptop and monitor have different types of ports, you’ll need an adapter. For example, if your laptop has an HDMI port and your monitor has a VGA port, you’ll need an HDMI-to-VGA adapter.
Make sure the external monitor is powered on and connected to a power source before attempting to connect it to your laptop.
Connecting Your Laptop to the External Monitor
Now that you have the necessary equipment, you can connect your laptop to the external monitor.
- Locate the video output port on your laptop. This is usually an HDMI, VGA, DisplayPort, or USB-C port.
- Locate the corresponding video input port on your external monitor.
- Connect one end of the appropriate cable to the video output port on your laptop and the other end to the video input port on your external monitor.
- If you’re using an adapter, connect it to the appropriate port on your laptop and then connect the cable to the adapter.
- Power on your laptop.
Once your laptop is powered on, it should automatically detect the external monitor. However, in some cases, you may need to manually configure the display settings.
Configuring Display Settings
After connecting your laptop to the external monitor, you may need to adjust the display settings to get the best possible picture.
On Windows, you can access the display settings by right-clicking on the desktop and selecting “Display settings.”
On macOS, you can access the display settings by going to System Preferences > Displays.
In the display settings, you’ll find several options for configuring your external monitor. These include:
- Display Mode: You can choose to duplicate your laptop’s screen on the external monitor, extend your desktop across both screens, or show the display only on the external monitor.
- Resolution: This setting determines the sharpness and clarity of the image on the external monitor. Choose the highest resolution supported by both your laptop and your monitor for the best results.
- Orientation: This setting allows you to rotate the display on the external monitor. This can be useful if you’re using the monitor in portrait mode.
- Multiple Displays: This option helps configure how windows and applications behave across multiple displays.
For a broken laptop screen, the best option is usually to set the display mode to “Show only on 2” (Windows) or select your external monitor as the primary display (macOS). This will disable the laptop’s screen and display everything on the external monitor.
Experiment with the different settings to find the configuration that works best for you.
Windows Display Settings
In Windows, you can press the Windows key + P to quickly access display options. These options include:
- PC screen only: Displays everything on the laptop screen.

What types of connections can I use to connect my broken laptop screen to an external monitor?
The most common connections are HDMI, VGA, and DisplayPort. HDMI is the most versatile, carrying both video and audio signals digitally. VGA is an older analog standard, still found on some older laptops and monitors, but it offers lower image quality than digital options. DisplayPort is another digital interface, often preferred for higher resolutions and refresh rates, and can sometimes be found as a Mini DisplayPort on laptops. The choice of connector will depend on the ports available on both your laptop and the external monitor.
Before connecting, check the specifications of both your laptop and the monitor to ensure compatibility. For example, if your laptop only has VGA, you’ll need a monitor that supports VGA input. Adapters are available to convert between different connection types, like VGA to HDMI, but image quality may be affected, especially when converting from digital to analog. It’s generally best to use the highest-quality connection available on both devices.
How do I enable the external monitor after connecting it to my laptop?
After physically connecting the monitor, you need to tell your laptop to use it. In Windows, press the Windows key + P to open the display projection options. You’ll see options like “Duplicate” (shows the same image on both screens), “Extend” (creates one larger desktop across both screens), “Second screen only” (disables the laptop screen and only uses the external monitor), and “PC screen only” (disables the external monitor). Choose “Second screen only” to use just the external monitor.
On a Mac, go to System Preferences, then Displays. Click the “Arrangement” tab. If the monitor isn’t automatically detected, click the “Detect Displays” button. You may need to uncheck “Mirror Displays” if you want to use the external monitor as an extended desktop. Once detected, you can drag the monitor icons to arrange them in the way they’re physically positioned relative to each other.
My laptop screen is completely black. How do I know if the external monitor is working?
Even with a completely black laptop screen, the underlying hardware might still be functional. Connect the external monitor using the appropriate cable. If the laptop recognizes the connection, you should see the external monitor light up. If nothing appears, try pressing the Windows key + P (Windows) or going to System Preferences > Displays (Mac) blind, and then using the arrow keys and Enter to select “Second screen only”.
If the monitor still doesn’t display anything, check the monitor’s power cable and ensure it’s plugged in and switched on. Verify the monitor’s input source is correctly selected to match the connection you’re using (e.g., HDMI 1, HDMI 2, VGA). Try a different cable to rule out a faulty cable. If you have another monitor or device, test it with the cable and laptop to isolate the problem.
Will connecting to an external monitor damage my laptop further?
Generally, connecting an external monitor won’t cause further damage to your laptop if the initial screen damage wasn’t caused by a deeper hardware issue. The external monitor connection operates independently of the internal display panel. However, if the original screen damage was a symptom of a larger problem, such as a failing graphics card or motherboard, using the laptop for extended periods with an external monitor could potentially exacerbate the underlying issue over time.
It’s essential to ensure the laptop’s cooling system is functioning correctly. Overheating can stress the graphics card, especially if it’s being pushed harder to drive an external display. Monitor the laptop’s temperature and avoid demanding tasks if it’s running hot. If you suspect a hardware problem beyond the screen, it’s best to consult with a qualified repair technician.
Can I close my laptop while using an external monitor?
Yes, you can usually close your laptop while using an external monitor, but you may need to adjust your power settings. By default, many laptops are configured to go to sleep or hibernate when the lid is closed. To prevent this, you need to change the “When I close the lid” setting in your power options.
In Windows, search for “Control Panel” and open it. Go to “Hardware and Sound,” then “Power Options.” Click “Choose what closing the lid does.” Under “When I close the lid,” select “Do nothing” for both “On battery” and “Plugged in” options. On a Mac, go to System Preferences, then Battery, and click “Power Adapter”. Ensure the “Prevent computer from sleeping automatically when the display is off” option is checked.
What if the resolution on the external monitor looks wrong or distorted?
Incorrect resolution is a common issue when connecting to an external monitor. First, ensure the monitor’s native resolution is correctly set in your operating system’s display settings. In Windows, right-click on the desktop, select “Display settings,” and then choose the correct resolution from the dropdown menu. On a Mac, go to System Preferences, then Displays, and select the “Scaled” option to choose the resolution.
If the recommended resolution isn’t available, or if the image still looks distorted, the graphics driver may be outdated or incorrect. Visit the laptop manufacturer’s website (e.g., Dell, HP, Lenovo) or the graphics card manufacturer’s website (e.g., NVIDIA, AMD) and download the latest drivers for your specific laptop model and operating system. Installing the correct drivers can often resolve resolution and display issues.
What if I don’t have the right cable to connect my laptop to the external monitor?
If you don’t have the right cable, the first step is to identify the available ports on both your laptop and the monitor. The most common options are HDMI, VGA, and DisplayPort. Once you know which ports you need to connect, purchase the appropriate cable online or from an electronics store. Make sure to get a cable of sufficient length for your setup.
If your laptop and monitor have different types of ports (e.g., laptop has HDMI, monitor has VGA), you can use an adapter to convert the signal. However, be aware that adapters may not always provide the best image quality, especially when converting from digital (HDMI, DisplayPort) to analog (VGA). For the best results, try to use a direct connection with the same type of port on both devices.
