Cable Matters VGA Extension Cable (VGA Cable Male to Female) - 1.8m

Product Information

A DVI-to-VGA adapter or cable would be needed if one connection is DVI and the other is VGA, with the DVI being compatible with analog signals.

DVI stands for Digital Video Interface, a standard for boosting the efficiency of data transfer from modern video graphics cards and enhancing the output quality of flatscreen LCD monitors. DVI-D cables can establish a direct digital link between a video source (such as video cards) and output device (such as LCD monitors). This type of DVI connector supports the faster transmission of higher-quality images compared to analog variants. VGA cables transmit analog video signals and are generally compatible with video resolutions up to 640×480.Length can also depend on application and cable configuration. For instance, a properly shielded VGA cable could still render a clear output at up to 150 feet. This is because shielding protects the VGA signal from electrical interference generated by other devices. It differs most from VGA because all modern video cards initially generate a digital signal. At the VGA output, this signal is converted into analog, which travels to the output device and is reconverted to digital. DVI-D eliminates the analog conversion process, enhancing the data transfer from source to display.

The DVI standard was introduced as a potential replacement for the VESA Plug and Display (P&D) standard. Its specifications were an upgrade over the digital-only VESA Digital Flat Panel (DFP) format used by older flatscreens. DVI cables are ubiquitous among video card manufacturers, with many cards being outfitted with DVI output ports. Considering all the above factors, it is safe to say that, generally speaking, even a 10-meter-long DVI cable would sustain a clear video output. Any longer, and the output would likely be either distorted or blank. Much like HDMI’s present-day status, VGA was almost universally adopted shortly after its introduction. However, unlike HDMI, which is still going strong, VGA is being phased out gradually and is no longer present on many newer devices. Finally, mini-VGA connectors are non-standard, proprietary ports used on some laptops and other systems as an alternative to standard VGA. This type is commonly seen on Apple iBooks, eMacs, early PowerBooks, and some iMacs, but it has also been included on several laptops by Sony and HP. Mini-VGA has been largely replaced with mini-DVI and, now, Mini-DisplayPort connectors. Smaller devices like laptops would commonly have a mini-VGA port installed. While these ports would be smaller than full-sized VGA connectors, they were just as efficient at transferring graphical signals.However, the exact cable throughput does not depend solely on length. Rather, as manufacturers create stronger video cards and larger monitors, shorter cable lengths may perform better. Today, VGA cables play a vital but fast-diminishing role in establishing video connections in home and commercial environments. They are majorly replaced with cutting-edge digital video interface standards like HDMI. A Video Graphics Array cable is one of the oldest connection standards found in computing equipment. Laptops, computer monitors, TV sets and videos cards are some of the devices in which we normally use these cables. Introduced in 1987, these cables were first developed by IBM, before they soon began to be built by other manufacturers with increased features. This was mainly developed at a time when analog signals were a norm. However, once digital signals came into the picture, these cables soon began to get enhanced with converters, thus enabling an analog to digital conversion. The capability of the DVI cord to carry both analog and digital signals gives it a unique advantage over HDMI and other “digital-only” video interfaces, as well as over VGA. Standard VGA cables remain vital for establishing a reliable video or graphics link between computers, monitors, projectors and high definition television sets in both domestic and commercial environments. It’s more common for smaller devices (such as compact laptop computers) to have a mini-VGA port installed, as opposed to a full-sized VGA connector, but these miniature versions play exactly the same role in terms of graphical signal transfer.

While the original DVI Type-A connector supported analog video signals like VGA, it was upgraded to support digital signal compatibility in 2002. Today, DVI connectors are capable of transmitting digital and analog signals. The DVI-D type is the most ubiquitous male connector, while DVI-I is the most commonly seen type for female DVI connectors, as it can accommodate all other formats. A video graphic array (VGA) cable carries analog signals and supports video resolutions up to and including 640 x 480. A super video graphic array (SVGA) cable carries analog signals and supports high-resolutions up to and including 800 x 600.When it comes to digital video cables (such as DVI-D or DVI-I), there is a misconception that a “purely digital” signal is “either-or”: either it works, or, if the cable is too long, it does not. And indeed, signal degradation does not take place in digital video signals in the same way it does in the case of analog signals. However, cable length and quality also make a difference in the output picture for digital cables. DVI is available in three main types: DVI-I (includes pins for digital as well as analog signals), DVI-D (includes sufficient pins for transferring digital signals only), and DVI-A (only analog signals). Thus, dual-link DVI has double the transmission power as well as enhanced throughput and signal quality. For instance, a DVI single-link 60-Hz LCD screen can display output in a 1920×1200 resolution, while a dual-link DVI would support a 2560×1600 display resolution. The main difference between VGA and HDMI connectors and cables is that VGA is used for carrying analogue signals, while HDMI is a digital standard. Each has its own unique advantages and disadvantages, depending on factors like the type of hardware you’re trying to connect and the install environment.

Critical VGA applications may even use equalizers and boosters to send VGA signals over long distances while countering the effects of electrical interference. Popular VGA boosters include the Ethernet (Cat5) wire or Cat6 for even longer cables. The VGA over CAT5/6 extender kit can support the transmission of 640×480 up to 300 meters and 1024×768 resolution up to 75 meters. High Definition Media Interface (HDMI) and DVI are common standards for linking video source devices to video output devices. DVI cables remain one of the best methods to establish a high-speed connection between CPUs and monitors and are still popular among certain classes of electronic devices. In other, more niche applications, DVI is used in conjunction with an adapter to link devices.

The first VGA cable configurations emerged in 1987. In the years that followed, this standard underwent numerous iterations and revisions by a variety of manufacturers. On the other hand, some DVI manufacturers provide cables that go up to 25 feet and even offer extensions that further increase the distance covered. However, results for such long cables can vary widely depending on hardware and configuration. Today, the hardware standard of choice seems to be the HDMI interface for high-definition media applications. The DVI standard is more exclusive to specific applications in the computer space.
