DVI to VGA Converters

There are a number of reasons to need a DVI to VGA converter. DVI is a fairly new way to connect a device to a TV or monitor, and there are more new video rendering devices built with DVI outputs than there are TV’s built with DVI inputs. However, VGA outputs have been around for a very long time, and they’re more compatible. Quite often, DVI to VGA converters (or adapters, as they are also known) can be the only thing that makes a DVD player compatible with a standard computer monitor, and it can a great tool for people whose entertainment devices come from different time periods or types of vendors.

DVI connectors are very convenient for both manufacturers and users because they can carry both analog and digital signals. This means that not only will they work on any system that has the right input/output, but they can also be adapted to suit different other types of adapters. In the same way that it is easy to make, find and buy a DVI to VGA adapter, it is just as easy to make, find and buy a DVI to HDMI adapter, despite the fact that HDMI and VGA are incompatible. DVI connectors are capable of transmitting both different kinds of signals, which makes it easy for them to connect to different types of devices.

However, the signal has to be the same between the two different devices. For example, a DVI cable can’t send a digital signal from one device and convert it to an analog signal for your monitor. DVI cables are marked to distinguish them by signal as well: DVI-D cables send and receive only digital signals, while DVI-A cables do the same with only audio. DVI-I cables can send and receive either signal, which means that you’ll need to specify the output on your device to be analog in order to connect it to a VGA input.

The term “DVI to VGA converter” is very important to understanding its usage. It is not to be confused with “VGA to DVI converter,” which is a very different subject. With a DVI to VGA converter, you’re taking an analog output from your DVI device, and just changing the end of it to fit a VGA input. The actual signal stays exactly the same. A VGA to DVI is a machine that changes the analog signal to a digital one. This is a complex process, and a VGA to DVI converter could cost hundreds of dollars.

A DVI to VGA does not cost nearly so much. You can find the simple adapter for between $15 and $25. It’s a pretty simple device, and you’ll be able to find it in any store that specializes in selling computer parts. They’re also very easy to find online. A converter with a cable (for length extension) will likely add about $10 to that price, but be careful not to make the cable longer than about 25 feet, or the signal will begin to degrade. This will severely hurt the image quality, or even cut the image off altogether.

A DVI to VGA converter can be a good way to attach certain devices to a monitor. However, it is rarely actually needed. Very few devices only come with a DVI output – only some small computer video cards. Most DVD players and computers (the most common devices for DVI outputs) will have multiple output options, meaning that you can just use another cord, like the red, white and yellow composite cables, to connect your device to a TV. A DVI to VGA converter is mostly only useful when the output device only has DVI, and your monitor or TV doesn’t.
