The Matrox G200eW (Nuvoton) WDDM 20 Windows Driver refers to a specific display driver for the Matrox G200eW graphics chip, which is typically used in systems that need basic graphics processing, such as embedded systems or low-end workstations. The driver is specifically designed to work with the WDDM (Windows Display Driver Model), which is a driver architecture introduced with Windows Vista and is used in modern versions of Windows (like Windows 7, 8, 10, and 11).
The WDDM 20 part of the driver name suggests it is designed to be compatible with Windows 10 and Windows 11 versions, as these operating systems use WDDM 2.0 (and higher) to manage graphics hardware. The driver from Nuvoton (a semiconductor company) is for systems that include Matrox G200eW graphics integrated into the hardware.
