It uses high quality and high bandwidth stream all in one connecting cable. Up to this day, HDMI with a total of 19 pins is currently the highest standard when it comes to high-end signal delivery from CPU-to-monitor and TV devices. The finished product delivered exceptional audio-visual signals in digital format. DVI picture quality is almost the same as HDMI except that it cannot carry audio as HDMI does.ĭeveloped in a collaborative effort by several companies, a high-definition multimedia interface or HDMI was created in the early 2000s in search of a portable and high-capacity connector. It is so versatile that it can even convert signals from either VGA or HDMI. It can also carry both digital and analog signals. With its 29 pins, it sent sharper and better images than VGA. It was designed to replace VGA as the standard of CPU monitor connections. It is rare that a monitor doesn’t have a VGA connector at the backĭVI, also known as Digital Visual Interface was created by the Digital Display Working Group in 1999. Technology-wise it is currently the lowest resolution for CPU-to-monitor display connection but is still very much the same standard today. Set in RGB color format (red, green, and blue), VGA deliversĢ56 colors on screen and is shaped like a trapezoid with 15 pins on it. Today, VGA is still much in use due to the stable color and quality that it provides. Later, the VGA subsequently leveled up to the “Super VGA” format, boasting resolutions that are ranging from 800 x 600 to 1024 x 768. It was the analog type of connector that delivered a resolution of 640 x 480 pixels, which at the time was already cutting edge. Let’s look at each of them and see how they work.Īlso known as Video Graphics Array, VGA was developed in 1987 by IBM. You can choose from any one of them to make a combination of both. They all look different as well as deliver different levels of quality of images to your computer screen. This is the main and only reason why you will have to consider using them. Nowadays, VGA, DVI, and HDMI are most likely the cable connectors and ports that you will find at the back of a standard computer monitor.

With that being said, let’s look into the kinds of ports and connectors that you would typically find behind your monitor.

Connecting two computers to one monitor is not rocket science, neither is it that simple by any means.
