Windows Display Driver Model (WDDM, [1] initially LDDM as Longhorn Display Driver Model and then WVDDM in times of Windows Vista) is the graphic driver architecture for video card drivers running Microsoft Windows versions beginning with Windows Vista.
The display driver may itself be an application-specific microcontroller and may incorporate RAM, Flash memory, EEPROM and/or ROM. Fixed ROM may contain firmware and display fonts. A notable example of a display driver IC is the Hitachi HD44780 LCD controller. Other controllers are KS0108, SSD1815 (graphics capable) and ST7920 (graphics capable)
Driver Verifier is a tool included in Microsoft Windows that replaces the default operating system subroutines with ones that are specifically developed to catch device driver bugs. [1] Once enabled, it monitors and stresses drivers to detect illegal function calls or actions that may be causing system corruption. It acts within the kernel mode ...
In the context of an operating system, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. [1] A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to ...
Unsuited video card (graphics card) drivers. Drivers that have values that the graphics card is not suited with. Overclocking beyond the capabilities of the particular video card. Software bugs in the application or operating system. The differing cases of visual artifacting can also differ between scheduled task(s).
BSoDs in the Windows NT family initially used the 80×50 text mode with a 720×400 screen resolution, but changed to use the 640×480 screen resolution starting with Windows 2000 up to 7. Windows 2000 used its built-in kernel mode font, Windows XP, Vista, and 7 use the Lucida Console font, and Windows 8 and Windows Server 2012 used the Segoe UI ...
KMS driver is an example of a device driver for display controllers and AMD Eyefinity is a special brand of display controller with multi-monitor support. RandR (resize and rotate) is a method to configure screen resolution and refresh rate on each individual outputs separately and at the same time configure the settings of the windowing system ...
Free and open-source drivers are primarily developed on and for Linux by Linux kernel developers, third-party programming enthusiasts and employees of companies such as Advanced Micro Devices. Each driver has five parts: A Linux kernel component DRM; A Linux kernel component KMS driver (the display controller driver)
