The BenQ GL2450 is a monitor, not a graphics card, so its driver helps Windows identify the display rather than control GPU performance. A compatible monitor driver can provide model-specific identification and display information, while your graphics card driver remains responsible for rendering and video output.

Key Features

• Model recognition: Helps Windows recognize the BenQ GL2450 by name instead of listing it as a generic monitor.
• Display configuration information: Provides monitor-specific details that Windows and display utilities can use when configuring supported display modes.
• Lightweight setup: A monitor driver typically uses an INF file and does not require a full graphics software suite.
• Works alongside your GPU driver: Complements the existing graphics driver without replacing it or adding unsupported display capabilities.

How to Install

1. Check compatibility before downloading. Confirm that the package is intended for the BenQ GL2450 and supports your version of Windows 11, 10, 8, or 7. Do not assume that an older monitor driver officially supports every Windows release.

1. Connect the monitor and extract the files. Make sure the display is connected securely and showing a picture. If the download is a compressed archive, extract it to a folder you can easily find.

1. Open Device Manager. Expand Monitors, then locate the entry corresponding to your GL2450. It may initially appear as Generic PnP Monitor. If several displays are connected, check the relevant monitor’s properties before proceeding.

1. Install the compatible driver. Right-click the monitor entry, choose Update driver or Update Driver Software, and select Browse my computer for drivers. Point Windows to the extracted folder and follow the prompts. Avoid forcing installation if Windows reports that the package is incompatible.

1. Verify your display settings. Restart if prompted, then check the monitor entry and available settings. Select the GL2450’s native 1920 × 1080 resolution and a supported refresh rate for a clear desktop image.

If Windows already detects the display correctly and offers its supported resolution, a separate monitor driver may not be necessary. For missing resolutions, flickering, or connection problems, also check the display cable and update the graphics adapter driver; installing a monitor INF alone may not resolve those issues.

Common Issues and Fixes

• Install fails or does nothing: The BenQ GL2450 package is often a ZIP containing INF/ICM files, not an EXE. Extract it, then use Device Manager > Monitors > Update driver > Browse my computer and select the extracted folder. Run as administrator if prompted.
• Monitor not detected / shown as Generic PnP Monitor: Check the video cable and the input selected on the GL2450; try another cable/port. In Device Manager, scan for hardware changes. If it still does not appear, test the monitor and cable on another PC.
• Version conflict or wrong monitor name: In Device Manager, enable View > Show hidden devices, remove duplicate/old BenQ monitor entries, then reinstall the GL2450 INF. Do not force-install a driver for a different BenQ model.
