Microsoft Flight Simulator v2.12, [13] [14] Jet, [15] Silent Service, [16] and Cyrus, [17] all released in 1985, offered EGA support, along with Windows 1.0. Sierra's King's Quest III, released in 1986, was one of the earliest mainstream PC games to use it. The first clone boards appeared in late 1985, lowering EGA's cost. [11]
Initially intended for use by computer monitors and video cards, the standard made its way into consumer televisions. The parameters defined by standard include horizontal blanking and vertical blanking intervals, horizontal frequency and vertical frequency (collectively, pixel clock rate or video signal bandwidth), and horizontal/vertical sync ...
Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source, such as a video display controller, to a display device, such as a computer monitor.

Generalized Timing Formula is a standard by VESA which defines exact parameters of the component video signal for analogue VGA display interface.. The video parameters defined by the standard include horizontal blanking (retrace) and vertical blanking intervals, horizontal frequency and vertical frequency (collectively, pixel clock rate or video signal bandwidth), and horizontal/vertical sync ...
