Best way to Convert VGA to DVI or DVI to VGA

VGA and DVI connectors are used to transmit video from a source (like a computer) to other source to display device (like a monitor, TV or projector). The main difference between DVI and VGA is in picture quality and the way the video signals travel.

VGA connectors and cables carry analog signals while DVI (Digital Visual Interface) can carry both analog and digital. DVI is latest and offers better, sharper display compared to VGA. You can easily tell them apart because VGA connectors’ color (and ports) are blue while DVI connectors’ color are white.

DVI and VGA are both very usable display connections, especially on older computers and monitors. While they are not the same connecters, and DVI does support higher resolutions than VGA, it’s simple enough to convert between them, allowing you to use DVI and VGA monitors and ports interchangeably.

Quality of Resolution (picture)

Before you get started, its best to understand something about image quality. Like with a lot of digital signals, your video output is only as good as its weakest link. VGA only supports a resolution of 1024×768, while DVI can support full 1080p HD at 1920×1080. As soon as you convert between them, the quality will reduce from whatever the source was to a maximum to 1024×768.

⚠️ Important: Switching from VGA to DVI will not scale up your picture.

Converting Between DVI and VGA

There are two common basic ways to convert from DVI to VGA. You can use a cable that does the conversion for you. It shall have a DVI connector on one end and a VGA one on the other. Plug one end into a DVI port and the other into a VGA, and everything will work normally. You can find cables like this pretty much anywhere online that sells electronics.

The other way to convert between these connectors is with a simple adapter. There are plenty of small adapters that have a DVI connection at one end and a VGA one at the other. Choose the right adapter that will plug into the device that you want to have either the DVI or VGA connection that you need, and connect everything up, using the adapter to replace the usual port. These are widely available too, and they’re relatively inexpensive. You can pick this one up from Amazon, and it’ll work in most situations.

Be sure to choose the right male/female configuration to match the connectors on your devices. It shouldn’t be too difficult, since both adapters and cables are widely available, and many devices use the same scheme.
