The BenQ XL2420T is a gaming monitor, and its monitor driver helps Windows recognize the display by its correct model name and use its supplied display information. Although it may be listed under GPU downloads, this package is a monitor driver—not a replacement for your NVIDIA, AMD, or Intel graphics driver.

Key Features

• Correct monitor identification: Replaces a generic monitor entry with model-specific information when the appropriate Benq driver is installed.
• Display mode information: Helps Windows identify supported resolutions and refresh rates. Available settings also depend on your graphics hardware, connection, and cable.
• Color profile support: If the package includes an ICC or ICM profile, it can provide a starting point for color management in compatible applications.
• Windows display integration: Provides monitor information for Windows display configuration. For Windows 11, 10, 8, or 7, check the package’s compatibility details before downloading.

How to Install

1. Check the download details. Confirm that the package is intended for the BenQ XL2420T and supports your Windows version. A monitor driver does not add capabilities beyond those supported by the display and graphics hardware.
2. Download and extract the files. Save the driver to an accessible folder. If it arrives as a compressed archive, extract it before continuing.
3. Open Device Manager. Expand Monitors, locate the entry corresponding to your connected XL2420T, then right-click it and select Update driver. The monitor may initially appear as a generic display.
4. Select the driver folder. Choose Browse my computer for drivers, point Windows to the extracted folder, and follow the prompts. If the package includes an installer, you can use that instead.
5. Review your display settings. Restart if prompted, then check the resolution and refresh rate in Windows display settings. If an expected refresh rate is unavailable, verify the connection type and update your graphics card driver separately.

Installing the correct monitor driver can improve device identification, but it will not increase GPU performance or guarantee additional refresh-rate options. If Windows reports that the best driver is already installed, check whether the monitor is identified correctly before attempting a manual installation.

Common Issues and Fixes

• Install fails or hangs: Run the BenQ XL2420T driver package as administrator, unblock the downloaded file if Windows marks it unsafe, and temporarily disable antivirus. Use the correct 32/64-bit package for your Windows version.
• Monitor not detected / shows “Generic PnP Monitor”: Confirm the XL2420T is powered on and set to the correct input (DVI, HDMI, or DisplayPort). In Device Manager, select Monitors > Scan for hardware changes, then update the driver manually and point it to the BenQ package.
• Version conflicts or wrong refresh rate: Uninstall any previous BenQ monitor driver and remove old XL2420T ICC/color profiles, restart, then install the latest BenQ package. Re-select 120 Hz/144 Hz in Windows display settings if needed.
