    Hi,

    Just to clarify—if you’re aiming for Extended Display (i.e., two monitors showing different things), you'll need to check the following:

    🔌 Port Type Matters

    • What port are you using to connect your external monitor—HDMI, USB-C, or VGA?
    • If you’re using a splitter (HDMI or USB-C), it likely only supports mirrored/duplicate display, not extended mode.

    🎯 Try an Active Graphics Adapter Instead

    • These adapters are designed to send distinct signals and support full extended display functionality.
    • Example: USB-C to HDMI with DisplayPort Alternate Mode, or a Thunderbolt dock with active display lanes.

    🛠️ Quick Checks:

    • Open Settings → Display and see if Windows detects a second screen.
    • Click Identify to see if the screens are independently recognized.
    • If it only shows one screen, your connection method might not support extended mode.

    Let us know your laptop model and what cable/port you're using—we can help tailor the setup from there 👍

    Well you can try the following :

    Adjust Scaling
    Look for Display settings → set up duplicate displays with matched resolutions.

    To get a duplicate display to show correctly, you need to ensure your display settings are properly configured for mirroring or extending the desktop. First, check if your computer recognizes both monitors in the display settings. Then, select the "Duplicate these displays" option if you want the same content on both screens, or "Extend these displays" for separate desktops. Adjust resolution and scaling for optimal viewing on each monitor.

    Here's a more detailed breakdown:
    1. Verify Monitor Detection:
    Right-click on your desktop and select "Display settings".
    Look for the "Multiple displays" section.
    Click "Detect" to ensure your computer recognizes both monitors. If a monitor isn't detected, try disconnecting and reconnecting it or checking its power and connection to the computer.
    2. Choose Display Mode:
    Duplicate these displays: If you want both monitors to show the exact same content, select this option.
    Extend these displays:
    If you want each monitor to display a separate part of your desktop, choose this option. You can then arrange the monitors' positions relative to each other in the display settings to control mouse movement between them.

    3. Adjust Resolution and Scaling:
    Select each monitor individually in the display settings.
    Adjust the "Display resolution" to match the recommended setting for each monitor.
    Adjust "Scale and layout" to ensure text and other elements appear at a comfortable size on each screen. You might need to customize scaling for each monitor if they have different resolutions.
    4. Consider Refresh Rate:
    If you're experiencing flickering or other display issues, check the "Refresh rate" setting for each monitor and ensure it's compatible with your monitor and graphics card.

    5. Check Connections:
    Ensure all cables (HDMI, DisplayPort, etc.) are securely connected to both the computer and the monitors.
    If using adapters, verify they are properly connected and working.
    Try swapping cables or monitors to rule out hardware issues.
    6. Update Graphics Drivers:
    Outdated or faulty graphics drivers can cause display problems. Update your graphics drivers through Device Manager or the manufacturer's website.
