VGA - Video Graphics Array

Analog RGBHV via 15-pin D-Sub - the video classic since 1987 that still drives projectors, industrial monitors and KVM switches.

VGA (Video Graphics Array) is the analog video standard introduced by IBM in 1987. The 15-pin D-Sub HD-15 connector carries three analog colour signals (R, G, B), separate horizontal and vertical sync, and a DDC bus for plug-and-play monitor identification (EDID). Despite being analog, VGA is still ubiquitous on projectors, industrial HMIs, KVM switches and signage equipment - the cable runs up to 30 m without repeaters and the signal is robust against EMI.

Frequently Asked Questions

Is VGA still relevant in 2026?

For projectors, signage and industrial HMIs yes - simple, cheap, robust over long cables. New consumer GPUs no longer have VGA outputs, but VGA-to-HDMI/DP active converters fill the gap.

Why is VGA called a high-density connector?

The HD-15 has 15 pins in a normal DE-9 shell - three rows of five, hence high density. The original DB-9 had only 9 pins.

Can VGA carry sound?

No - VGA is video only. Audio uses a separate jack or RCA pair on consumer gear.
