The VGA is one of the more prevalent video connectors found on computers today. The Video Graphics Array connector, also known as the VGA Connector, is an industry standard connector commonly used for computer video output. Originating from the 1987 IBM PC and its VGA card, the 15-pin connector eventually went onto be ubiquitous on computers, projectors and even high-end television sets. The popularity of the VGA has not waned, but in order for you to use one without purchasing a new computer you need to know how to recognize the different types so that you can choose which type is right for you.
VGA to DVI-D converter: A VGA to DVI-D converter uses the same video output as a traditional VGA monitor. In essence, this means that you are only using one port to connect your laptop to your computer, and this port is usually not all that user-friendly, especially if you are using a computer with a small keyboard or a touch-pad. For those with a laptop that is just starting out, a VGA to DVI-D converter may be the ideal option for you.
VGA to DVI-D: Similar to VGA, the VGA to DVI-D conversion utilizes the same video port that your typical VGA monitor uses to connect to your computer. If you are going from an older computer to a newer one, you may not want to opt for a VGA, especially if you plan on using it on a regular basis. DVI is generally less commonly used as a video output and is often used as a video input. Those who regularly use computers without a VGA monitor may find that a VGA to DVI-D conversion is more preferable to keep the cost of the monitor down.
DVI to HDMI – The HDMI connection is a new connection that has come onto the market in recent years. While the VGA used to be the standard video connection, the HDMI provides a much higher resolution and is considered to be the better option. While some still favor the VGA or DVI connections, most computer manufacturers have moved towards supporting the HDMI standard.
Mini VGA to DVI-D – There are actually three different video adapters on the market that support the DVI-D format. These are mini-VGA to DVI-D converter boxes, digital video adapters (DVI-D to DVI-D), and digital video transmitters (DVI-D to HDMI). All of these converters take the place of the standard VGA connectors and provide an effective video connection for those who have a VGA based computer. However, DVI connections tend to be a little less reliable than a full range DVI cable, so it is recommended that you use one of the other two options for those who use DVI-D.
Most of the VGA to DVI-D converters on the market provide analog signals only, but there are a few options out there that convert the analog signal into digital. In addition, some of the newer converters will also convert the digital signal to analog in addition to the digital ones. These additional conversions will improve the picture quality somewhat, and if you are using DVI-D with your computer monitor, you may be able to tell that your picture is sharper than it was before as the additional signal improves the quality of the picture. If you need to use an analog signal, then it is recommended that you use one of the DVI-D to VGA cables, though if you are using VGA and want to convert to an analog signal, then you can always use a VGA to DVI-D cable.
