One of the limitations of WDDM driver model version 1.0 is that it does not support multiple drivers in a multi-adapter, multi-monitor setup. If a multi-monitor system has more than one graphics adapter powering the monitors, both the adaptors must use the same WDDM driver. If more than one driver is used, Windows will disable one of them.

DisplayLink launched its first semiconductor product family, the DL-120 and DL-160 USB 2.0 graphics devices, in January 2007, [10] signaling a change in the company's business plan from FPGA-based systems to semiconductors. The DL-120 and DL-160 allow up to six additional monitors to be added to a PC through USB 2.0.
TGA graphics are built into the motherboards of Tandy computers. The PCjr uses a custom monitor with a unique 18-pin plug, [15] but an adapter (with the same DE-9 connector and pinout as IBM's CGA/EGA) can connect it to the IBM Color Display or similar 4-bit digital RGBI monitor. [16] The Tandy 1000 provides the DE-9 connector directly. [17]
IBM 5151 monitor driven by a Monochrome Display Adapter (MDA) The MDA was released alongside the IBM Color Graphics Adapter, and in fact could be installed alongside the CGA in the same computer. A command included with PC DOS permitted switching the primary display between the CGA and MDA cards. [10]
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)

Color Graphics Adapter text and graphics modes. Text modes use a font with 8×16-pixel character cells [1] and have 400 rows of pixels. [3] There are six possible color arrangements: [2] Default 256-colour palette - Low 4 bits intensity, high 4 bits colour; 16-colour palette - Makes the PGC behave as two 16-colour planes. If high 4 bits are 0 ...
DisplayPort (DP) is a proprietary [a] digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). It is primarily used to connect a video source to a display device such as a computer monitor. It can also carry audio, USB, and other forms of data. [1]
