Difference between DVI and Dual-link DVI

When it comes to video connections, there are a few different types you might come across. You have VGA, DVI, and HDMI. Each of these connections has its own benefits and drawbacks. In this blog post, we’re going to take a closer look at the difference between DVI and dual-link DVI. We’ll discuss what each connection is used for, as well as the pros and cons of each one. So if you’re looking to buy a new graphics card or just want to know more about video connections, read on!

What is DVI?

DVI is a digital display interface that is commonly used in computers and other devices. DVI is capable of transmitting both digital and analog signals, and it can be used with a wide variety of monitors and displays. DVI is also backward compatible with older analog interfaces, making it a versatile option for both new and old computers. DVI is the preferred interface for high-resolution displays, and it is also commonly used in home theater systems. DVI connectors are available in a variety of sizes and shapes, and they can be adapted to work with other types of displays. DVI is a reliable and widely-used interface that offers high-quality video performance.

What is Dual-link DVI?

Dual-link DVI is a digital visual interface used to connect computers to display devices. It is capable of transmitting up to 2560×1600 resolution (higher than 1080p HD) at a refresh rate of 60 Hz. Dual-link DVI uses two pairs of data transmission lines (known as links), which allows it to achieve higher bandwidths than single-link DVI. Dual-link DVI is also backward compatible with single-link DVI, meaning that it can be used with displays that only support single-link DVI. Dual-link DVI is the most common type of DVI found on high-end graphics cards and monitors.

Difference between DVI and Dual-link DVI

  • DVI is the digital replacement for analog VGA. DVI comes in single link and dual link varieties. Dual-link DVI carries twice as much data as single-link DVI and is thus able to support resolutions higher than 1920×1200. DVI uses its resistive impedance to maintain compatibility with HDMI devices, so it will not support Audio over HDMI without an adapter. DVI is the best option when looking for the clearest image possible because it transmits digital data rather than converting it to analog.
  • Dual-link DVI is primarily used for high-resolution monitors that have a scaler built-in, since these types of monitors are not as common as they once were it is slowly being phased out by HDMI which can carry both audio and video signals. Even though DVI can carry HDCP content, it was not designed for that purpose and thus does not support some of the features required for HDCP compliance such as support for Content Scramble System (CSS). As a result, DVI is slowly being replaced by HDMI as the standard for digital video connections.


While DVI and Dual-link DVI connectors may look the same, they are not interchangeable. Make sure you know which type of connector your monitor or graphics card uses before making a purchase. If you’re not sure, contact the manufacturer for more information. With this knowledge in hand, you should be able to make an informed decision when it comes time to buy a new monitor or graphics card. Thanks for reading!
