Do VGA-to-DVI Adapters Work?

Do VGA-to-DVI Adapters Work?

Picture this: you want to connect your PC to your monitor. 

When you check your computer’s ports, it only has VGA. But for your monitor, it only has a DVI port available. 

So what do you do? The fastest option is to utilize the DVI port of your monitor by using an adapter that will connect the VGA port of your computer. 

If this is a method you aren’t familiar with, we’ll be glad to walk you through the whole process of making this setup. 

Do VGA-to-DVI Adapters Work?

a VGA to DVI adapter

Yes, a VGA to DVI connection works and there are adapters that help facilitate this type of connection. 

But before we move, let’s first talk about how a VGA port and cable varies from a DVI port and cable.

VGA, also known as Video Graphics Array, has been around for several decades. It’s a video connection that transmits analog signals from one source to another. A VGA port sends or receives these signals through a VGA cable. 

And since it only sends video signals, you have to use another cable and a set of speakers to run audio. 

This is why there’s always a set of speakers and a 3.5mm audio cable connected to your computer whenever you play something using a VGA connection. 

On the other hand, DVI continues to be a relatively popular connectivity method today because it uses digital signals just like HDMI.

It can also carry analog signals, which, unfortunately, HDMI can’t do. This is another reason why a VGA-to-DVI adapter will work because DVI can read analog signals coming from the VGA port. 

Despite being similar in this area, there is no way for a DVI port to read a VGA signal and vice versa directly. So if you have a VGA port sending out signals, you’ll need a third-party accessory to convert the analog signal to a digital one (a signal DVI can read). 

This is where a VGA-to-DVI adapter  will be used.

How Do I Connect a VGA Computer to a DVI Monitor?

There are many types of VGA-to-DVI adapters, but all of them will have a similar process of connecting a VGA computer to a DVI monitor.

This is usually how it’s done:

  1. Turn off both devices.
  2. Connect one end of the VGA cable to the VGA port of the adapter . You can tighten the connection by twisting the screws at the side of the VGA cable. 
  3. Connect the free end of the VGA cable to the VGA output port at the back of your system unit. 
  4. Connect one end of the DVI cable to the DVI port of the adapter. 
  5. Then connect the other end of the cable to your monitor’s DVI input port. 
  6. Turn on your computer and monitor. The monitor should be able to show the wallpaper of your computer. 

Tip: If the monitor isn’t read, you can check the Display Settings and make sure that the connected monitor is read by your computer. 

Take note that the DVI and VGA cables are often not included with the adapters.
