VGA 1987 HD15F Analog 2560 x 1600 @ 85 Introduced with IBM x86 machines, but became a universal analog display interface. Nearly ubiquitous display interface in use for PCs, Laptops and computer projection units from 1990 onwards (until a digital interface supplants it)
Mac-II/Quadra 1987 DB15F Analog 1152 x 870 @ 75 Macintosh Mac-DB15F and Sun-13W3 were similar in capability to VGA. Some Sun machines used 4 or 5 BNC connectors to transfer video signal.
13W3 1990? DB13W3 Analog 1152 x 900 @ 76 SUN computer systems
DVI 1999 DVI Both 2560 x 1600 @ 60 Recent video cards DVI was the digital display interface that won over several competing standards to answer the need for a digital computer->display link. The marketplace had previously been almost exclusively analog.
ADC 2000 Apple-ADC Both 2560 x 1600 @ 60 Apple computers Proprietary modification of DVI
HDMI 2003 HDMI-A/B/C Digital 2560 x 1536 @ 120 Many A/V systems and video cards (including motherboards with IGP) HDMI use a content protection system HDCP which only allows devices with HDCP key(s) to transmit high-definition content.
UDI 2006 "USB alike plug with single row of 26 pins" Both  ? None as of 2007 Intel has withdrawn from the promoter group and supports another standard, DisplayPort.
DisplayPort 2007 20-pin (external)
32-pin (internal)
Digital 2560 x 1600 @ 70
(for 6.9 Gbit/s link)
None as of 2007
upcoming: ATI RV670 based graphics cards and NVIDIA G92 graphics cards (both as OEM optional implementations)
DisplayPort introduced the 128bit-AES to replace HDCP. DisplayPort also includes a notebook internal connector, something the HDMI and DVI specifications lack.
