The BenQ XL2420G G Sync Gaming Monitor driver helps Windows identify the display and use its supplied monitor information. This monitor package is separate from your graphics card driver: NVIDIA G-SYNC operation also depends on compatible graphics hardware, the correct connection, and graphics driver settings.

Key Features

• Accurate monitor identification: Allows Windows to recognize the BenQ XL2420G rather than relying solely on a generic monitor label.
• Display configuration information: Supplies monitor-specific information that can help Windows and your graphics driver identify supported display modes.
• Color profile support: If the download includes a manufacturer color profile, you can assign it through Windows Color Management. A supplied profile does not replace individual screen calibration.
• Complements your graphics driver: Provides monitor-level setup information while your GPU driver handles rendering, refresh-rate controls, and G-SYNC configuration.

How to Install

1. Check the package before downloading. Confirm that it lists the BenQ XL2420G and supports your installed version of Windows 11, 10, 8, or 7. Do not assume an older monitor package is officially supported on every Windows release.

1. Connect and prepare the display. Power on the monitor and connect it to your graphics card. For G-SYNC, use the monitor’s supported DisplayPort connection with compatible NVIDIA hardware. Extract the downloaded files if they are compressed.

1. Install the monitor driver. If a setup utility is included, follow its instructions. For a package containing an INF file, open Device Manager, expand Monitors, right-click the entry corresponding to this display, and select Update driver.

1. Locate the extracted files. Choose Browse my computer for drivers, select the driver folder, and follow the prompts. If Windows reports that the best driver is already installed, verify the package’s compatibility before attempting a manual installation. Restart if prompted.

1. Review your display settings. Select the monitor’s native resolution and an available supported refresh rate in Windows display settings or your graphics control panel. If you plan to use G-SYNC, enable it in NVIDIA Control Panel and confirm that the monitor is operating in the appropriate mode.

If the display is not detected correctly, check the cable, input selection, and graphics driver first. Installing a monitor driver alone will not add unsupported resolutions or enable G-SYNC on incompatible hardware.

Common Issues and Fixes

• Install fails: Run the BenQ driver package as administrator. If Setup still errors, install manually via Device Manager > Monitors > Update driver > Browse and select the extracted INF. Reconnect the monitor afterward.
• Monitor not detected or G-Sync missing: Connect the XL2420G directly to the GPU with a DisplayPort 1.2 cable—G-Sync does not work over HDMI/DVI or most adapters. Power-cycle the monitor and use Device Manager > Scan for hardware changes.
• Version conflicts: Uninstall any old BenQ/generic monitor driver in Device Manager, check “Delete the driver software,” reboot, then install the current package. If Windows Update restores an older driver, roll back or update again.
