The ViewSonic VX2260WM is a 22-inch widescreen LCD monitor. The "Windows driver" you're referring to is likely a software package that enables your computer to interact properly with the monitor, offering optimized display resolutions, refresh rates, and functionality like automatic adjustments or features specific to the monitor. Most of the time, modern versions of Windows automatically detect and install the necessary drivers for a monitor when you plug it in, so you may not need to install anything manually. However, in certain cases, you might want to install or update the driver for better compatibility or additional features.
