During this transition, the way the cables recognized resolution changed. However, a transition started in the late 1990s from analog signal broadcasting to digital. These pins were originally meant to detect what type of monitor was being used. Pins 4, 9, 11, 12, and 15 are no longer functional or have a limited function. These segments are then synchronized to make sure they match and that is what we see. The connection sends a vertical and a horizontal picture and then blends the two together.

You probably aren’t aware of this, VGA connections don’t send a signal. Pins 13 and 14 control the horizontal and vertical synchronization respectively. Without these grounding pins, a VGA cable would provide an inconsistent picture. Any excess electricity will be sent through these pins. Pins 5, 6, 7, 8, and 10 are all grounding pins, which prevent signal interference. The VGA connection can combine each variable together and that is why it is called a 16-color scheme. The three colors plus intensity give the output four variables. The system can also change the intensity of the colors.

The system uses those three colors to create all the other colors on the display. The first three pins are responsible for red, green, and blue. The traditional VGA ports have 15 jacks for 15 pins. The defining feature of VGA connectors is the large number of pins that plug into the holes in the port. If the copper pin is bent, the trapezoid shell is bent, or a screw breaks it would make the connector difficult or impossible to use. One major issue with this design is that there are multiple possible failure points. Within the trapezoid, there are 15 pins that correspond to 15 holes in the female connector. The male connector has two screws on either side, which correspond to two screw holes on the female port.

Still, some monitors, video cards, older laptops, and televisions feature VGA ports. So, VGA cables are growing less and less popular. Most modern standards for video transmission use digital signals (later in the article). This was revolutionary at the time and replaced the S-Video. IBM originally designed the standard for 640×480 displays. The VGA standard was first introduced in 1987. VGA connectors have 15 pins that each contribute to how the colors blend on the screen. It is a standard for video output that uses analog signals rather than digital signals.
