If you’re wondering, what a VGA port looks like, this article is for you. It describes the VGA port, its functions, and how to use it.

What is a VGA port?

The VGA connector is used for connecting your computer and laptop to display devices.

It can be used for receiving video signals from a computer output and into a projector for display.

VGA stands for video graphics array. It was first developed in 1987 and was developed by IBM.

As time went by, it became a common feature of display devices like desktop and laptop computers, HDTVs, and projectors.

The VGA connection used to be very common. Now, it is being replaced by more efficient connection types.

This does not mean that it is now scarce. It is still common in older devices today.

The VGA connection makes use of analog RGB signals. For this reason, it displays at a native resolution of 640 × 480.

It supports higher resolutions, up to HD. However, it displays them in a lower quality on large screens.

To use the VGA port, you will require a VGA cable.

There is another way to identify the VGA port. There is usually a symbol close to it.

The symbol is a rectangle bracketed by two lines on each side.

The 15 pins on the VGA cable all serve various functions. Together, they transmit video and sync signals.

Pins 1, 2, and 3 transmit the RGB component video signals. Pins 6 – 8 transmit the RGB analog grounds.

Like that, all the other pins serve their own individual functions. Some are in charge of horizontal and vertical sync.

VGA connections transmit analog video signals. HDMI on the other hand, transmits digital signals.

This means that HDMI can access a higher amount of transferable data. As a result, it displays pictures in higher resolution and quality.

VGA has its advantages. It experiences less lag because it doesn’t have to process analog signals before displaying.

However, HDMI is the more modern and convenient choice. It transmits both audio and video signals.

3. Is a VGA port the same as a serial port?

vga port and serial port

A serial port is an interface for serial communication. Information is transferred in or out of it in sequence.

Serial ports on computers can be used to transmit data between the computer and certain peripherals like printers and mice.

The serial port cannot transmit video signals. This makes it very different from the VGA port.

The only similarity between VGA and serial ports is in their appearance. They have a similar D shape, but the serial port has a 9 pin arrangement.


Your projector may come with different ports for different purposes. It can be trying to figure out the function of each one.

The connector aids the streaming of analog video signals but it has its limitations.

Some modern devices still come equipped with VGA ports. However, it is increasingly being replaced by newer interfaces.

Digital transmission interfaces like the HDMI and DisplayPort are becoming more common.
