The Lenovo LI2215sD is a model of Lenovo LCD monitors, and the Windows driver for this monitor is typically the Generic Monitor Driver or, in some cases, a Digital Video Interface (DVI) or DisplayPort driver provided by Lenovo to ensure proper communication between the monitor and the operating system. However, most modern monitors, including the Lenovo LI2215sD, do not necessarily require a specific driver to work with Windows, as they usually work well with the built-in Plug and Play (PnP) support provided by Windows.
