The AOC 2270W Windows driver is a software that allows your Windows computer to communicate with the AOC 2270W monitor. This driver ensures that your computer is able to properly display graphics on the AOC 2270W monitor and supports features like display resolution, refresh rates, and color calibration. Typically, most monitors are plug-and-play and don't require a separate driver to work, but the driver may be useful for certain advanced features (like custom resolutions, specific graphics settings, or optimal performance).
