Amazon Basics DisplayPort to DVI Cable with Gold-plated connectors (1.8 m/6 Feet)

Product Information

Ultimately, choosing between these two types of connections depends on your specific needs and monitor setup. Choosing the Right DVI Connector for Your Needs IEEE 1394 was proposed by High-Definition Audio-Video Network Alliance ( HANA Alliance) for all cabling needs, including video, over coax or 1394 cable as a combined data stream. However, this interface does not have enough throughput to handle uncompressed HD video, so it is unsuitable for applications such as video games and interactive program guides. When it comes to analog vs. digital signals, the difference lies in the way information is transmitted. Analog signals are continuous waves that represent sound or images, while digital signals are discrete binary code (0s and 1s) that represent the same information. Delving into the world of DVI cables, you may come across terms like dual-link and single-link. But what’s the difference in quality? This connection exclusively transmits digital signals. It is the most often used connector for connecting DVI cards to LCD monitors. DVI-D is available in single-link and dual-link configurations. The dual-link format is more powerful and has a higher data transfer rate than the single-link format.

The DVI connector on a device is given one of three names, depending on which signals it implements: But before you go ahead and buy a DVI cable, ask yourself this: what’s the purpose of your device and how do you plan to use it? Are you a gamer or an artist who requires high-quality digital signals? Or maybe you just need an analog signal for regular office work? The number of pins and the configuration of the pins on every graphics card or motherboard with a DVI connector varies according to the type of connector. DVI devices manufactured as DVI-I have support for analog connections, and are compatible with the analog VGA interface [1] by including VGA pins, while DVI-D devices are digital-only. This compatibility, along with other advantages, led to its widespread acceptance over competing digital display standards Plug and Display (P&D) and Digital Flat Panel (DFP). [2] Although DVI is predominantly associated with computers, it is sometimes used in other consumer electronics such as television sets and DVD players. Warning: DVI is no longer considered the premiere display technology is because it’s limited solely to visual content

Eiden, Hermann (July 7, 1999). "TFT Guide Part 3 - Digital Interfaces". TomsHardware.com . Retrieved 29 March 2012. HDMI completed what DVI had started – bringing fully digital AV signal transmission to home entertainment. In addition to digital, some DVI connectors also have pins that pass an analog signal, which can be used to connect an analog monitor. The analog pins are the four that surround the flat blade on a DVI-I or DVI-A connector. A VGA monitor, for example, can be connected to a video source with DVI-I through the use of a passive adapter. Since the analog pins are directly compatible with VGA signaling, passive adapters are simple and cheap to produce, providing a cost-effective solution to support VGA on DVI. The long flat pin on a DVI-I connector is wider than the same pin on a DVI-D connector, so even if the four analog pins were manually removed, it still wouldn't be possible to connect a male DVI-I to a female DVI-D. It is possible, however, to join a male DVI-D connector with a female DVI-I connector. [12]

The digital signal provides a crisper image by avoiding analog distortions or interference. Supported Display Modes: Single Link vs Dual Link DVI Display ModeVESA Plug and Display (P&D) Standard, Version 1" (PDF). Video Electronics Standards Association. June 11, 1997. Archived from the original (PDF) on July 4, 2003. Unified Display Interface (UDI) was proposed by Intel to replace both DVI and HDMI, but was deprecated in favor of DisplayPort. Because P&D was a physically large, expensive connector, a consortium of companies developed the DFP standard (1999), which was focused solely on digital video transmission using a 20-pin micro ribbon connector and omitted the analog video and data capabilities of P&D. [4] :3 [5] :4 DVI instead chose to strip just the data functions from P&D, using a 29-pin MicroCross connector to carry digital and analog video. [8] Critically, DVI allows dual-link TMDS signals, [9] meaning it supports higher resolutions than the single-link P&D and DFP connectors, which led to its successful adoption as an industry standard. Compatibility of DVI with P&D and DFP is accomplished typically through passive adapters that provide appropriate physical interfaces, as all three standards use the same DDC/EDID handshaking protocols and TMDS digital video signals.

DVI-I single-link connectors have 23 pins (18+5) and dual-link connectors have 29 pins (24+5). DVI-I connectors do not convert analog and digital signals but can accept digital or analog signals – just not both at the same time. If a video card, monitor and cable all have DVI-I connections with the ability to support both analog and digital signals, one mode of operation has to be selected. True to their purpose, DVI-I connectors will work with all three DVI cable types. However, a male DVI-I cable will not fit in a female DVI-D connector due to its additional analog pins. Hence, when considering the rarity of a DVI-A connector, a DVI-D cable is the most commonly applicable out of the three cable types. When DVI was designed, most computer monitors were still of the cathode ray tube type that require analog video synchronization signals. The timing of the digital synchronization signals matches the equivalent analog ones, so the process of transforming DVI to and from an analog signal does not require extra (high-speed) memory, expensive at the time. Although DVI is considered an older display technology and has connections and ports that look similar to VGA, they’re not the same. One of the biggest differences is the supported signals.With this knowledge in mind, you’ll be able to make informed decisions when selecting the right cable for your setup.
