Adding a side monitor to your computer setup can significantly boost your productivity, enhance your gaming experience, or simply make multitasking a breeze. But what happens when you plug it in and… nothing? Don’t worry; getting that second screen up and running is usually a straightforward process. This guide will walk you through everything you need to know to turn on your side monitor and configure it to your liking.
Checking the Physical Connections
Before diving into software settings, ensure all your physical connections are solid. This might seem obvious, but it’s the most common culprit behind a non-functional side monitor.
Verifying the Cables
First, double-check the video cable connecting your computer to the side monitor. Are you using HDMI, DisplayPort, DVI, or VGA? Ensure the cable is securely plugged into both the monitor and the computer’s graphics card. A loose connection can prevent the signal from reaching the monitor.
Look for any signs of damage to the cable itself. Frays, bends, or exposed wires can disrupt the signal. Try a different cable if you suspect the current one is faulty.
Confirming the Power Supply
Make sure the monitor is receiving power. Is the power cable properly connected to both the monitor and a working power outlet? Check that the power switch on the monitor is turned on. A small LED indicator usually lights up to confirm power.
If the monitor has an external power brick, ensure it’s properly connected and receiving power. Try plugging the monitor into a different power outlet to rule out any issues with the power source.
Identifying the Correct Ports
Many computers have multiple video output ports. Make sure you’re using the correct port on your computer. If you have a dedicated graphics card, the video output ports on the motherboard might be disabled when the graphics card is installed. Connect the monitor to the ports on the graphics card instead.
Desktop computers usually have ports on both the motherboard and the dedicated graphics card. Laptops typically have HDMI and/or DisplayPort outputs.
Configuring Display Settings in Your Operating System
Once you’ve confirmed the physical connections, the next step is to configure your operating system to recognize and enable the side monitor. The process varies slightly depending on whether you’re using Windows or macOS.

Why is my side monitor not being detected by my computer?
There are several reasons why your side monitor might not be detected. Begin by checking the physical connections. Ensure the cable connecting the monitor to your computer is securely plugged in at both ends. Try a different cable or port to rule out faulty hardware. Confirm the monitor itself is powered on and set to the correct input source (e.g., HDMI, DisplayPort).
If the physical connections are secure, the issue might lie in your computer’s display settings. Open your display settings (usually found in your system settings or control panel) and look for a “Detect” or “Identify” button. Clicking this will prompt your computer to scan for connected monitors. If the monitor is still not detected, consider updating your graphics card drivers to the latest version, as outdated drivers can sometimes cause compatibility issues.
How do I configure my side monitor to extend my desktop?
Extending your desktop allows you to use your side monitor as an additional workspace. To configure this, access your display settings. In Windows, right-click on the desktop and select “Display settings.” On macOS, go to “System Preferences” then “Displays.” You should see representations of both your primary monitor and the side monitor.
Within the display settings, locate the option for “Multiple displays.” Select “Extend these displays” (or a similar option depending on your operating system). You can then drag the monitor icons to arrange them in the order that matches your physical setup. This ensures that your mouse cursor moves seamlessly between screens in the correct direction. Click “Apply” to save the changes.
What’s the difference between extending and mirroring my display?
Extending your display treats your side monitor as an extension of your primary screen, providing more workspace. This means you can drag windows and applications from one monitor to the other, effectively doubling your screen real estate. It’s ideal for multitasking and having multiple applications open simultaneously.
Mirroring, on the other hand, duplicates your primary display onto your side monitor. Both monitors show the exact same content. This is useful for presentations, where you want to show the same information on both your laptop screen and a larger display, or for sharing content with someone sitting next to you.
How do I change which monitor is considered my “main” display?
The “main” display is where your operating system typically launches applications and displays the taskbar (Windows) or menu bar (macOS). To change which monitor is designated as the main display, navigate to your display settings, as mentioned previously. Identify the monitor you want to set as the main display.
In Windows, select the monitor and check the box labeled “Make this my main display.” On macOS, drag the menu bar (the white bar at the top of the display icon) to the display you want to designate as the main one. Applying these changes will immediately switch the primary monitor, and newly opened windows will appear on the new main display.
My side monitor has a different resolution than my main monitor. How do I fix this?
Having monitors with different resolutions can sometimes cause visual inconsistencies. The best approach is to set each monitor to its native resolution, which is the resolution it was designed to display optimally. You can find the native resolution in the monitor’s manual or on the manufacturer’s website.
Within your display settings, select the icon representing your side monitor. Look for a dropdown menu or setting labeled “Resolution.” Choose the native resolution for that specific monitor. If you can’t find the native resolution listed, make sure your graphics card drivers are up to date. Applying the correct resolution should provide the sharpest and most accurate image on each screen.
Can I use different orientation settings (portrait or landscape) on my side monitor?
Yes, you can often use different orientation settings on your side monitor to suit your needs. Portrait mode, where the monitor is oriented vertically, can be particularly useful for tasks like coding or reading long documents. To change the orientation, go to your display settings and select the monitor you want to adjust.
Look for an option labeled “Orientation” or “Rotation.” You’ll typically find choices like “Landscape,” “Portrait,” “Landscape (flipped),” and “Portrait (flipped).” Select the orientation you desire. Keep in mind that you might need to adjust the physical position of the monitor accordingly. Applying the new orientation may require a system restart.
What if my side monitor flickers or displays distorted images?
Flickering or distorted images on your side monitor can indicate several potential problems. Start by checking the cable connecting the monitor to your computer. Ensure it’s securely plugged in and not damaged. Try using a different cable to see if that resolves the issue. Also, make sure the refresh rate setting in your display settings is compatible with your monitor’s capabilities.
If the cable isn’t the problem, the issue could be related to your graphics card drivers. Outdated or corrupted drivers can cause display issues. Try updating to the latest drivers or, if the problem started after a recent update, consider rolling back to a previous version. In some cases, the monitor itself might be faulty, so testing it with another computer can help determine if it needs to be repaired or replaced.
