A second display or second displays is a common term describing the multi-monitor setup with just one additional monitor attached. Today it is particularly common to have one workstation with two monitors connected where the second monitor is referred to as the second display. Many tablets will serve as a second display connected to a laptop. [22]
Prior to the DDC, the VGA standard had reserved four pins in the analog VGA connector, known as ID0, ID1, ID2 and ID3 (pins 11, 12, 4 and 15) for identification of monitor type. These ID pins, attached to resistors to pull one or more of them to ground (GND), allowed for the definition of the monitor type, with all open (n/c, not connected ...

AV Multi (gold-plated male plug) AV Multi: Sony proprietary. Combines composite video, S-Video, RGsB/YP B P R (both use same pins) and stereophonic sound (two analog ...
The data is transmitted via the cable connecting the display and the graphics card; VGA, DVI, DisplayPort and HDMI are supported. [citation needed] The EDID is often stored in the monitor in the firmware chip called serial EEPROM (electrically erasable programmable read-only memory) and is accessible via the I²C-bus at address 0x50. The EDID ...
The Video Graphics Array (VGA) connector is a standard connector used for computer video output. Originating with the 1987 IBM PS/2 and its VGA graphics system, the 15-pin connector went on to become ubiquitous on PCs, [1] as well as many monitors, projectors and HD television sets.
The motivation for including analog is to keep compatibility with the previous VGA cables and connectors. VGA pins for HSync, Vsync and three video channels are available in both DVI-I or DVI-A (but not DVI-D) connectors and are electrically compatible, while pins for DDC (clock and data) and 5 V power and ground are kept in all DVI connectors ...
The Hercules Graphics Card was released to fill a gap in the IBM video product lineup. When the IBM Personal Computer was launched in 1981, it had two graphics cards available: the Color Graphics Adapter (CGA) and the Monochrome Display And Printer Adapter (MDA).
The later VGA standard built on this by mapping each of the 64 colors in from a larger, customizable, palette of 256. Standard EGA monitors do not support use of the extended color palette in 200-line modes, because the monitor cannot distinguish between being connected to a CGA card or being connected to an EGA card outputting a 200-line mode.
