The ViewSonic G90fb-2 is a CRT (Cathode Ray Tube) monitor, typically used for display purposes in a variety of professional, office, or home settings. Unlike modern flat-screen monitors (LCD/LED), CRT monitors like the G90fb-2 do not require complex drivers for basic functionality. Most of the time, they will work with generic Windows display drivers that are built into the operating system.
However, if you're looking for a specific ViewSonic G90fb-2 Windows driver, it could be for enhanced features or settings management, such as resolution control, color calibration, or other advanced features.
