The rate at which technology changes is extremely fast and it continues to accelerate year after year. As soon as you buy a device, no matter how advanced and expensive it might be, chances are that just a few months later a new superior product will be released. Whatever feature a product has, it will probably be outdated in less than a year, as new standards and discoveries advances the field. When it comes to video standards, the one that replaced VGA is DVI, a technology of video interface that is found on every single computer sold today. If you're looking to understand more about the DVI vs VGA debate, read on and you can see a comparison of the two standards.

The quality of the signal is very important in an electronic device and it has to be as close to the original as possible. VGA and DVI do just that, they carry electronic signals, in most cases from a PC to a monitor. The reason why DVI is much more common than VGA is because it has superior performances.

First of all, the VGA connectors have 15 pins and they take the analog signal and display it on monitors. Since this is analog, it doesn't work as well on recent monitors, including LCDs or any other type of digital display. It was invented in 1987.

As for the DVI standard, it was developed in 1999 and it replaced the VGA standard on most computers. They are compatible with VGA and HDMI and they transport the digital signal, uncompressed. The connectors from this standard have a total of 29 pins and they can carry both digital and analog signal. All the digital displays can use DVI signals if they come with it onboard. Recently, even DVI is starting to get replaced by HDMI, which is the next step in the evolution of video transmission technology.

There are two kinds of DVI here, called DVI-A and DVI-D. The first one stands for DVI analog and the other for DVI digital. The digital version is partially compatible with HDMI. The analog version is the one compatible with VGA signal. Since it's partially backwards compatible, the DVI connector can carry both types of signals, or it can carry just analog or just digital signals. All DVI devices can support at a minimum the 640x480 resolution, to make sure there is a minimum of interoperability.
