Most Common Computer Video Display Connectors

What are video display connectors?

Digital video display connectors are ports or connections that help it transmitting the highest quality video signals. These connectors are easy and quick to use and very safe. High-quality video requirement is the need of every individual.

These connectors use transition minimized differential signaling (TMDS) to transmit uninterrupted digital video signals from source to display. This results in a very high-quality image and visual in the form of an image.

Digital visual interface has evolved over the course of time by an industrial body DDWG to send the digital data from an electronic device, be it PC or a monitor to a digital display or screen, such as LCD (Liquid Crystal Display) monitor. There is a new type and method every day or our own advancement because we want better quality every day.

Video devices used all around the world our each having a different type of interfaces. However, the most common trait shared by all of them is that they are easily connected. The makers make sure that the interface is for the basic average users to use it easily and to make sure to bring the full out of it.

They are designed for the user in such a way that they can connect and disconnect without any issue related to the installation of the release of the cords or any sort of another physical issue.

Types of video display connectors…

There are various types of video display connectors for computers or personal laptops like BNC, Display port, HD15 VGA, HDMI micro, HDMI mini, HDMI, DVI, LFH59, M1, RCA, RF-CF type, S Video. Let us start step-by-step, knowing about each and every one of these types of video connectors. First and foremost we have,

BNC

It stands for Bayonet Neill Concelman connector. It is a coaxial radio frequency (RF) electrical connector that is more effective and actively preferred over normal coaxial connectors. The range of various radio frequency is up to 3 gigahertz. The voltage is under 500 volt DC. It is versatile and finds its use around a lot of areas like audio, video, networking, and communication. Most commonly nowadays the coaxial cables of the Ethernet always end with BNC connectors. The connection is locked by a male BNC connector that has a hole that fits into the main wire. It’s used in any type of connections like

1. High-quality video network
2. Avionics
3. Radio antenna connection and for communication
4. Test equipment and device for many electronic devices
5. Analog signaling

For higher frequency requirement, a TNC connector, modification of BNC, comes into play which is a threaded version.

Display Port

It is one of the first display connectors to rely on data transfer in the form of packets. This form of data transfer is mostly found in technologies like Ethernet, USB, and similar other technologies. A display port input, which is a monitor port cannot accept anything other than a display port signal. As we know, display port is primarily used for the purpose, mainly, to output an optical signal. This work is mainly coupled at the same time with audio production. People always look for the price when buying any product. You can find this for both low and high price depending upon your budget and what you require it for. Display Port is a notch higher on the video result scale. It gifts HD video resolution, which is bigger the output containing multiple videos and audio channel at the same time.

HDMI

It can make a significant difference in home theatre system. It can carry 1080 pixel high definition signals, and it supports 8 channels of audio and video. It is just that all the components of home theatre should be compatible with HDMI. It encodes, carries, and decodes digital signal to very high definition on display like HD TVs. It uses TMDS, as mentioned earlier, to move into from one place to another. The sending device such as HD DVD player encodes the signal to reduce the number of transition between 1 net is on and 0 that is off. Two parts of cables work in contrast. One part carries the signal, and the other part carries an inverse copy of the signal. The receiving device decodes the signal. It tries to measure the difference between the signal and its inverse as they decode it to get a beautiful video. It is a great method where audio and video is transmitted in a single cable of two parts. Other types of connectors need to separate cables for audio and video data. HDMI cables carry both audio and video data together. It is a convenient method to avoid digital to analog and analog to digital conversion. This typically gives the best picture and sound quality when compared to other connectors.

DVI

It stands for the digital visual interface. It can be of 3 connection types DVI-I, DVI-D, and DVI-A. DVI-I is a combination of both the other types of a digital visual interface. DVI-D is digital only whereas DVI-A is the only analog. DVI is not a lot preferred, but it is more common with projectors. DVI can link up to 2 TDMS links. It provides a really high-quality picture for home cinema components. This is used when your device has DVI connections rather than HDMI. This is usually ahead of component video cable, an S video cable and other cables. It was initially created with the intention of making a market ample for transfer of digital video content. It transmits uncompressed digital video and can be configured to support various features.

S – Video

They can run with and can connect with various devices like TVs, DVDs and DVRs along with high-end video cassette recorders, digital TV receivers, and game consoles. It functions by dividing a video signal into separate luma and chroma signals, providing a better signal for the use with devices like standard TVs, DVD players, projectors, etc. The so-called ” TV out” port on the back of many video cards is actually an S video port.

So basically there are various types of computer video display connectors available in the market. Users need to research well and choose the best connector available for the computer considering all the requirements needed.
