    Since selecting Extend does not take effect, reset the graphics driver with Windows key + Ctrl + Shift + B, then test whether Windows detects the external display.

    1. Reset the graphics driver

    1. Leave the monitor connected and powered on.
    2. Press Windows key + Ctrl + Shift + B.
    3. The screens may blink and a sound may play.
    4. Press Windows key + P and test Extend again.

    This key sequence resets the active graphics driver without uninstalling it.^1^

    2. Check whether Windows detects the monitor

    1. Right-click the desktop and select Display settings.
    2. Under System > Display, look for two numbered display boxes.
    3. If only one appears, expand Multiple displays and select Detect.
    4. If two appear, select the external display and verify that it is not configured as disconnected.

    If Windows still shows only one display:

    • Disconnect docks, hubs, and other accessories, then connect the monitor directly to the laptop.
    • Reseat the cable at both ends.
    • Try another HDMI or DisplayPort cable.
    • Try another video-output port, if available.
    • Test the monitor with another computer to distinguish a monitor/cable problem from a laptop problem.^1^

    If this is a USB-C connection, the laptop port, cable, and adapter must support the appropriate display Alternate Mode. Connect the adapter directly to a display-capable USB-C port rather than through a hub; if the laptop has multiple USB-C ports, test another one.^2^

    3. If this started after an update, roll back the display driver

    1. Right-click Start and select Device Manager.
    2. Expand Display adapters.
    3. Right-click the graphics adapter and select Properties.
    4. Open the Driver tab and select Roll Back Driver.
    5. Restart Windows and test Extend.

    Rollback is specifically applicable when the problem began after a driver or Windows update.^1^

    4. If rollback is unavailable, reinstall the display driver

    1. In Device Manager > Display adapters, right-click the graphics adapter.
    2. Select Uninstall device.
    3. Select Attempt to remove the driver for this device, then Uninstall.
    4. Restart the laptop.
    5. Return to Device Manager > Display adapters.
    6. Right-click the adapter and select Update driver > Search automatically for drivers.
    7. Test the external display again.^1^

    Removing the driver temporarily affects display operation, so save open work before performing this step.

    Multiple-monitor limitation

    If you are extending to two external monitors through a simple display splitter, that configuration cannot create independent extended displays; a splitter only duplicates one signal. Multiple independent outputs require supported graphics hardware and, depending on the laptop, a compatible docking station or USB display adapter.^1^

    Welcome Kitty Holt,

    Thanks for reaching out to Microsoft Q&A Forum. I understand that the Project feature on your laptop stays on PC screen only and does not switch to Extend.

    To help narrow this down, could you please confirm:

    • When you choose Duplicate or Second screen only, does the external display show anything, or do those options also fail to apply?
    • Is the external display a monitor or a projector, and what is your laptop's brand and model?

    Please make sure you already tried the Q&A Assist steps. In addition, please try the following:

    1, Set Extend from Display settings instead of the Project panel

    • Open Settings, select System, then select Display.
    • Expand Multiple displays and open the drop-down menu next to the display options.
    • Select Extend these displays, then select Keep changes when asked.

    2, Check which display adapter Windows is using

    • Right-click Start and select Device Manager.
    • Expand Display adapters.
    • If you see Microsoft Basic Display Adapter, Windows is not using the full graphics driver. Download and install the graphics driver for your exact laptop model from the laptop manufacturer's support website.

    3, Install pending optional driver updates

    • Open Settings and select Windows Update.
    • Select Advanced options, then Optional updates.
    • Expand Driver updates, select any display, graphics or chipset updates, then select Download & install.
    • Restart the laptop after the installation.

    4, Set the display mode in the graphics control app

    • Open the graphics app installed on your laptop, such as Intel Graphics Command Center, NVIDIA Control Panel or AMD Software: Adrenalin Edition.
    • Go to the Display or Multiple displays section and set the mode to Extended desktop.
    • Apply the change and check whether Windows keeps the setting.

    Looking forward to your update.
