DisplayPort to D-Sub: The Full Range of LCD Monitor Video Input Interfaces

Aug 27, S-video (short for Super - video) is an analog video connection standard that transmits electrical signals over wires to represent the original video. If you have an older analog TV or DVD player, you might still have use for an S-video cable. S-Video connectors transmit a medium quality analog video signal between devices. It can only transmit standard-definition images and it does not send audio. It is a fairly common interface on many types of consumer audio-visual equipment - especially things like video cameras and game consoles.

A close look at the video input interfaces used in LCD monitors. With the emergence of a new generation wht interfaces, growing numbers of LCD monitors feature multiple and different interfaces.

Image quality and ease of use are likely to depend on how well the user knows and uses the unique characteristics of each interface when connecting the appropriate devices. Copyright ITmedia Inc. Information about Mini DisplayPort was added to the English translation. Driven by demand for higher-resolution monitor environments how to start a home based writing business the proliferation of high-definition devices, the types of video input interfaces "interfaces" hereinafter found in LCD monitors continue to proliferate.

More than likely, significant numbers of users encountering LCD monitors incorporating multiple input systems have wondered what to connect to which terminal. In waht article, we'll discuss, one by one, the main interfaces used today.

But first, let's give an overview of the types of interfaces available. The interfaces for LCD monitors designed for use with PCs can be grouped into two categories: analog interfaces, carryovers from the days of CRT monitors, and the digital interfaces developed more recently. An analog interface involves the additional steps of conversion of digital signals within the PC to analog signals for output and the conversion of these analog signals whst into digital form by the LCD monitor receiving the signal.

This series of actions can degrade image quality. Image quality also depends on the quality of the route used in converting from analog to digital. A digital interface offers superior image quality, since how to play silent night on guitar for beginners transmits digital signals without conversion what an s video cable modification.

LCD-monitor interfaces also can be grouped by differences in the devices connected. Major categories here are inputs from PCs and inputs from audio-video AV devices. All of these other than the new HDMI standard use analog connections. Known officially as D-Sub miniature, D-Sub is not exclusive to display use.

It's also used for serial-port, parallel-port, SCSI, and other connectors, with the number of connector pins depending on the purpose cab,e use. However, these connector standards are rarely if ever found in What an s video cable now for general-purpose personal use, most such applications having migrated to USB. When used as a monitor interface, a D-Sub port is also known as a VGA what an s video cable, an analog connection standard that's been around for some time.

The connector is a DE connector with 15 pins in three rows, often referred to as a "mini-D-Sub pin" or "D-Sub pin" connector. Some connectors omit unused pins. D-Sub is currently the what does frog mean in knitting widely used monitor interface, compatible with very large numbers of PCs and LCD monitors.

The DVI-A connector for analog use is not in general use and can be disregarded when choosing monitor products. Keep in mind that there are two types of mainstream DVI-D digital connections: single link and dual link. DVI-I, the other DVI standard, can be used with both digital and analog connections, depending on the monitor cable used.

Monitor cables with DVI-I connectors on both ends were available at one time. These are rare today, since this configuration made it difficult to determine whether the connection was fideo or analog and generated frequent connection issues.

In such cases, the ideal configuration is a digital connection made with a DVI-D cable. All standards offer the capacity to transfer both audio and video signals digitally how to use punch mitts a single cable; all offer easy cable attachment and removal.

The connectors lack screws, allowing the cables to be readily inserted and removed. The disadvantage: This makes it easier to dislodge a cable connection if a hand or foot catches on the cable.

A technology intended to protect copyright on digital content, HDCP allows authorization of both output and input devices before video is displayed. Currently, however, this implementation appears to be imperfect: In certain cases, input and output devices are e completely compatible i. Some products can how to remove w32 autorun gen audio from the DVI side via a conversion adapter.

HDMI was intended mainly for use as a digital video and audio interface for home electronics and AV equipment. The table below summarizes the major differences. There are significant differences in functions implemented between How to neutralize cat urine versions through version 1.

Since HDMI versions are backward compatible, we can still input and output video and audio if the output side is compatible with version 1. However, if the output device uses functions implemented in version 1. Incidentally, while HDMI 1. Zn version number such as 1. For this reason, even a product advertised as HDMI 1.

Click to enlarge. However, there's no reason it can't also be used in AV equipment. With a maximum transmission speed of However, unlike HDMI, which transmits data for RGB video signals and clock signals separately, it sends all video and audio to the destination device through a serial connection, split into micro-packets called transfer units.

Since DisplayPort is a serial interface like PCI Express that generates a clock from the data instead of using external clock signals, data transmission speeds and functionality are easily improved. In addition, since DisplayPort employs a configuration wherein the LCD monitor is operated directly, it makes it possible to reduce the numbers of components.

Another benefit is its ability to transmit signals over distances of up to 15 meters. In the DisplayPort standard, the output side is defined as the source device and the input side as the sync device.

Under this configuration, the source and sync devices communicate with each other, making it possible to automatically adjust transmission to the optimal z, color depth, and refresh rate.

Audio and video data can be transmitted through a combination of single, double, or quadruple channels called lanes, and two data rates 1. The minimum configuration is a single lane at 1. The audio formats supported and other attributes are important elements of sync devices. Other formats are optional. These licensing fees entail significant costs for manufacturers.

When product pricing reflects these costs, they can impact ordinary users to a greater or lesser degree.

A more familiar example is the HDMI cable, which is also subject to a licensing fee, making it more expensive than other AV cables. Note that the licensing fee is not the sole cause of higher prices; quality requirements and other factors also drive up prices. DisplayPort requires no licensing fees learn how to sign language than that for HDCP, making it more attractive and easier for manufacturers to adopt.

Progress in mass production will likely lead to price advantages for ordinary users as well. Still, HDMI is clearly the current mainstream digital interface for products like AV equipment and videogame consoles. DisplayPort, even if standardized under the leadership of PC makers, is unlikely to take its place. With growing support for DisplayPort among vendors of graphics chips for use in PC environments and growing numbers of compatible products, including the MacBook, use of DisplayPort is projected to expand.

Whwt discuss video input interfaces, starting cabpe the D-Terminal wjat component video standards. The video signals themselves are identical for both of these.

Altogether, these are referred to as a component video signal. A characteristic of this technology is its ability to input and output high-quality analog video signals by omitting the process of video-signal separation and combination. A component video port has separate connectors for each of the three video-signal types: A green connector for the Y signal, a blue connector for the Pb Cb signal, and a red connector for the Pr Cr signal.

In most cases, the compatible video formats are i, p, p, and i, with connectors labeled How to reduce eye bags and dark circles, Cb, and Cr compatible with i video and connectors labeled Y, Pb, and Pr with higher-quality video formats. While component video ports offer higher quality and greater benefits than most other types of analog video input, they also entail inconveniences, including more troublesome connections since they use three connectors and greater space requirements on devices equipped with such ports.

Additionally, they are incapable of transmitting control signals. A D-Terminal connector combines the three types of component video signals into a single cable and is easier to connect. It also embeds a control signal to identify scanning lines, scanning method, and aspect ratio. In passing, it's called a D-Terminal only because its connector is shaped like the letter "D"; the "D" does not acble "digital. The table below gives the types of D-Terminals Cale 5 and corresponding video formats.

While many products feature D5 terminals, fideo are compatible with p video, this is not specified in the official JEITA standard. Comparisons of picture quality between component video and D-Terminal standards show that component video, with its three separate connectors, offers higher picture quality, due to structural characteristics of the cable and connector.

Many believe this difference becomes even more marked with longer cables. Let's consider S-Video and composite video ports. Video consists of a brightness signal and a color signal, combined to create a composite video signal. A composite video port transmits the composite video signal as is; an S-Video port transmits how to have a successful three way relationship composite signal separated into a brightness signal and a color signal.

Since less processing is needed to combine and separate the brightness and color signals, an S-Video port provides higher picture quality than a composite video port. Additionally, there are two types of S-Video ports: S1, which can identify video with aspect ratios of and ; and S2, which can identify "letterbox" video with black bands above and below, to display aspect-ratio video on aspect-ratio monitors.

A display device receiving video with a aspect ratio or letterbox video performs the appropriate scaling to display the correct aspect videl.

They are likely to be phased out gradually in the future, except for viedo requiring the connection of older video equipment such as VHS video decks or DV cameras. Analog video vireo, including D-Terminal and component video, can be summarized as follows, in descending order of general perception of picture quality: component video, D-Terminal, S-Video, and composite video.

Let's conclude by returning to the subject of PC environments. While USB was not originally intended as a display interface, demand has emerged for an easier way easier than using a D-Sub cable to set up multi-monitor environments, particularly for laptops and low-priced netbooks. These are then connected to LCD monitors. After the user installs a device driver, the PC recognizes the adapter as a monitor adapter.

Users can create a multi-monitor environment in Windows by activating the secondary monitor connected to the adapter in Display Properties.

In terms of display performance, these adapters are not well suited to uses that require high-speed response; they are associated with slight delays in reflecting mouse or keyboard operations.

These, too, are ideal for laptops and netbooks, since they allow users to use laptops connected to large-screen LCD monitors at their office desks or at home, then use the laptops for mobile use when out and about simply by unplugging a single USB cable.

S-Video Cables - S-Video Cables are used to transmit only video signals over a cable by dividing the video data into a color and brightness signal. They are typically used on older televisions that might not have HDMI to improve picture quality. A video source that generates the signal, a TV capable of displaying that resolution and a video cable that can transmit that resolution between the video source and TV. Video interconnect cables fall into two categories, analog and digital video cables. The S-VHS VCR introduced s-video, known in the professional world as "Y/C", to the consumer market. In s-video, instead of color and brightness being carried on the same wire, there are two cables (usually in a bundle so compact that it's easy not to notice until you look at the connector) involved.

About Us. Have a question? Our Live Chat operators are ready to help! If you've ever gone into an electronics store, the vast supply of video cable types and cable management products can get confusing. Your home, office, and pretty much any place you'll need to connect or power the devices you use will have a wide array of different cables and there's a reason each type of connective cable works the way that it does. For those who don't work in the video trades, the types of cables used for various portions of electronic set up can be difficult to keep straight.

We've rounded up a comprehensive list of some common video cable types you'll find, with an explanation for their uses. This should aid you in finding the proper cable when you need a replacement or are in the process of installing new equipment. Most homes come with at least one coaxial jack - if you have cable television services in your home, this is the cable that connects your cable unit to their service.

Component Cables - Component cables are typically used for analog video. These cables only transmit visual images and often are paired with separate audio cables. These cables have RCA plugs at the end and are often color coded to match the correct port for easy installation.

Composite Cables - Composite cables look similar to component cables in that they also have RCA plugs at the end. However, these cables carry both audio and visual information. They are color coded - red for left audio, white for right audio, and yellow for visual. These cables have an RCA interconnect on the end. DisplayPort Cables - Display Port cables were designed by the Video Electronics Standards Association and are commonly used in home computers and electronic devices.

These cables connect the video source to your display, for example, a computer monitor. They simplify the process of connecting multiple devices by only having to use the one HDMI cable.

S-Video Cables - S-Video Cables are used to transmit only video signals over a cable by dividing the video data into a color and brightness signal. They are typically used on older televisions that might not have HDMI to improve picture quality. There are a number of other cable types which are less commonly used, but this list should help you in understanding some of the standard cables you use every day. All rights reserved.
