DVI cables come in three types: DVI-A for analog, DVI-D for digital, and DVI-I for both. Dual-link cables can transmit higher resolution pictures. Cable length is also important, with some devices only able to transmit signals over cables up to 16 feet long.
To choose the best digital video interface (DVI) cable, you’ll need to consider the components you’re working with. There are three different DVI standards, each of which is designed for a particular situation. DVI-Analog (DVI-A) is required when components are analog, DVI-Digital (DVD-D) is designed for situations where both components are digital, and in both cases DVI integrated cables (DVI-I ). . The other major factor to consider is whether a cable is dual-link or single-link, since a dual-link DVI cable can transmit a higher resolution picture. You’ll also want to choose an appropriately long DVI cable, as some devices can’t transmit a signal over cables longer than about 16 feet (5 meters).
The digital video interface (DVI) standard was designed to replace analog video graphics array (VGA) connectors. DVI connectors are typically found on computer video cards, monitors, and some high-definition televisions (HDTVs). Unlike VGA, which was designed for analog signals only, the DVI standard provides analog and digital formats. Both formats use the same plug design and pin location, although they use different pin layouts.
When trying to choose the best DVI cable, you’ll first need to decide whether to get a digital, analog, or integrated version. This choice depends on the equipment you are using. In most cases, your equipment will be all digital, but it’s important to check this before buying cable. If both your monitor and computer use digital connections, you’ll need to select a DVI-D cable. These cables may provide better picture quality than analog cables, but DVI-A is still required under certain circumstances.
You will need to select an analog DVI cable if you have a VGA monitor or TV that uses DVI-A. It’s also important that your computer is capable of generating an analog signal, as the cable won’t do any sort of conversion for you. If you need to convert from digital to analog, you’ll need additional hardware. The third type of DVI cable can be used for both analog and digital since it has pins for both, but DVI-I doesn’t do any conversion either. A DVI-I cable can be used for digital-to-digital or analog-to-analog connections, but it won’t convert between the two.
Another factor to consider when looking for the best DVI cable is length. The original DVI standards required cables no longer than 16 feet (about 5 meters), as it was difficult for a video card to reliably transmit a signal over long distances. Some hardware can handle longer cables, so you may want to determine what the correct length is for your specific equipment. If you experience artifacts on the display, the cable is too long. To eliminate artifacts or unwanted digital effects, you will need to use a shorter cable or install a signal amplifier.
