Overview of VGA Connector
What is VGA connector?
The Video Graphics Array (VGA) connector is a three-row 15-pin DE-15 connector.
Many video cards, computer monitors, laptop computers, projectors, and high-definition televisions provided 15-pin VGA connectors.
The original IBM PS/2 defined different signal assignments.
The IBM 8513 monitor defined pin 5 as Self Test.
The IBM PS/55 Display Adapter defined pin 9 as + 12V.
When the system unit is turned on, it turns on a specific monitor.
Shorter VGA cables are unlikely to cause significant signal attenuation.
BNC usually does not support supplementary signals, such as DDC.
Availability
Newer video cards usually do not have VGA output.
The DVI-I output, still containing analog VGA compatible signals, is usually omitted.
