The useful distinction
Recognize it. Then verify it.
The familiar VGA-style HD15 connector has three rows of five contact positions. [C016A]
Dell P2016 Rev. A02, page 15, assigns its VGA example as follows: 1 red video, 2 green video, 3 blue video, 4 ground, 5 self-test, 6 red return, 7 green return, 8 blue return, 9 computer 5 V / 3.3 V, 10 sync ground, 11 ground, 12 DDC data, 13 horizontal sync, 14 vertical sync, 15 DDC clock. [C016B]
The NEC VT37 manual, page 55, differs from the Dell P2016 example: pin 5 is ground rather than self-test, pin 9 is not connected rather than a computer-supply label, and pin 11 is SCART sync rather than ground. [C016C]
NEC VT37 page 14 documents separate RGB/VGA and audio cables for its computer connection. Its page-55 COMPUTER connector table contains video, sync and control assignments rather than an audio channel. [C016D]
NEC VT37 page 16 documents a component source connected to its COMPUTER input through the ADP-CV1 15-pin-to-three-RCA adapter and a three-RCA component cable. The manual separately identifies composite VIDEO input and audio connections. [C016E]
The DVI2VGAE instructions describe a DVI source feeding a VGA monitor or projector and include USB power support for low-powered DVI ports. [C016F]

Specifications and limits
A boundary, not an omission to guess around.This record is an identification starting point. The engineering reference provides a source-scoped contact example, not measured mating tolerances, fabrication approval or a verified compatibility result. Use the exact device and accessory documentation for signal role, pin assignments and operating limits.
