The BenQ GL2240 (Analog) refers to a 21.5-inch LCD monitor from BenQ, typically connected via an analog VGA input (as opposed to digital DVI or HDMI). The Windows driver for the BenQ GL2240 monitor helps your computer correctly communicate with the display, ensuring optimal resolution, color accuracy, and refresh rate settings. While most modern monitors, including the BenQ GL2240, typically work without the need for dedicated drivers (Windows often installs the necessary plug-and-play drivers automatically), there may be additional software or monitor-specific drivers that help with color calibration, screen resolution settings, and other advanced features.
