DisplayPort Cable- Everything That You Need to Know in 2021

Nowadays, we transmit both video and audio data between two points. This transmission is possible with the help of digital cables. Some of which include HDMI, DisplayPort, and DVI.

In today’s article, we will look at DisplayPort cables and everything that you need to know about it. Our scope will cover a lot ranging from the comparison between HDMI and DVI, custom DisplayPort cables, and more.

As such, it will be right to start this article by answering the question, “what are DisplayPort cables?”

1. What are DisplayPort Cables? 

DisplayPort cables are conductors of signals with DisplayPort connectors at their terminals.

DisplayPort cables are specific cables for carrying both video and audio signals simultaneously from source to display units. These display units may include computer monitors, TVs, or screens.

Also, these are different types of DisplayPort cables. Some have varying transfer speed, quality of data, and more.

2. What is a Display Port?

 

A DisplayPort is a digital interface for transmitting both video and audio signals simultaneously from source to display units. It is sometimes as DP. To further say, this DisplayPort is of two types, namely: Standard and the Mini DisplayPort.

It is essential to note the difference between a DisplayPort and a Display port. In light of hardware connectivity, a display port is an opening on an electronic device. This opening is suitable for DisplayPort cables connecting to transmit signal either from it or to the device.

2.1 What does DisplayPort look like?

 A DisplayPort looks similar to the HDMI cable. It has a square-like shape with one of the sides of the square halved at 45 degrees. The picture below shows more details about DisplayPort.

2.2 Where do we use Display Port Cables?

There are various places where we use DisplayPort cables. Sometimes we use them in our day to day lives, not knowing that we use them.  DisplayPort finds applications also with most high-resolution display devices and other devices such as;

  • Monitors
  • Laptops
  • Video games
  • Televisions
  • Projectors
  • 4K Screens
  • Custom devices

Mainly, DisplayPort finds applications in areas that require a rich graphic display.

2.3 History of Displayport Cables

We will dedicate this section briefly to the history of DisplayPort. Our focus is on the origin of these cables and what was in place before discovering DisplayPort cables.

Before the development of DisplayPort, video data was in transmission. The VGA cables served effectively in transmission until the need for transmitting high-resolution images with less arose. Of course, that’s what innovation entails – achieving more with less. This need led to the development of HDMI cables. They transmit digital signals in a single piece. After which, DisplayPort cable became useful for high-graphics PCs. 

However, today, manufacturers like HP/COMPAQ, DELL, and other PC makers now produce Display ports. 

2.4 The Significance of DisplayPort Cables

DisplayPort cables play a very significant role in our society today. Some of its features make it superior to cables with similar characteristics.

Also, the self-latching mechanism present in DisplayPort cables allows for secure connections. This feature best suits areas prone to vibrations. It will lock the link and prevent unexpected disconnection. 

Furthermore, DisplayPort’s auxiliary bidirectional data channel allows it to carry data for webcams, touch panels, and microphones. This feature makes it helpful with visual call software like Zoom, Skype, and more.  Also, DisplayPort can drive display panels directly. It can replace internal and board-to-display links in some electronic devices.

More so, the inability of DVI to transmit HD digitals makes DisplayPort cables more significant. It solves this problem. 

Lastly, using the right adapters can connect DisplayPort to DVI, HDMI, or VGA.

2.5 DisplayPort Cable and Connectors Overview

We will consider DisplayPort cable under the following sub-headings

3. DisplayPort Cable and Connectors Overview

Compatibility: DisplayPort cables are compatible with all DisplayPort devices. As a result, they fit and effectively transmit data. The device’s features and functions are not barriers.

However, you might experience a variety of transmission speed with different cables. These differences can be traceable to the length and quality of the cable. 

Cable length

Cable length affects the speed of transmission. A length above two (2) meters can come in varying quality. In general, there is no limit to the length of the DisplayPort cables. 

3.1 Certification and Cable bandwidth

Also, it is needful to note specific requirements a DisplayPort cable must meet to be certified. The Video Electronics Standards Association (VESA) is responsible for setting up these requirements. These standards, therefore, put manufacturers in check of cable quality. Not all DisplayPort cables transmit high quality. DisplayPort cable bandwidth values are dependent on the quality of the cable.

3.2 Connectors

The two types of DisplayPort connectors present are

  • Full-size DisplayPort connector
  • Mini DisplayPort connector

Each of the DisplayPort connectors performs the same function and with the same quality of transmission. However, the only difference here is that they come in different shapes, sizes, and designs.

3.3 Types of DisplayPort Connectors

We will like to talk more about the two types of DisplayPort connectors mentioned in the previous chapter.

4. Types of DisplayPort Connectors

We will like to talk more about the two types of DisplayPort connectors mentioned in the previous chapter.

4.1 Standard DisplayPort Connector

A Full-size connector is another name for the standard DisplayPort connector. This name change was to distinguish the Mini DisplayPort as both types are standard DisplayPort. The full-size connector has a self-latching mechanism that locks-in when connected. This mechanism prevents unexpected removal and keeps the connection firm. It also uses a friction lock. The full-size DisplayPort has a dimension of 0.476 cm (height) x 1.610 cm (width) x 0.888 cm (depth). 

4.2 The Mini DisplayPort Connector

The Mini DisplayPort connector is a minimized version of the full-size DisplayPort. Apple Inc was the first to develop and incorporate it into its MacBook Pro and MacBook Air. The license later became free for use by VESA and subsequently became the main DisplayPort standard.

Unlike the Full-size DisplayPort connector, the Mini DisplayPort (mDP) uses only a friction lock to keep connection in place. Its receptacle has a dimension of 0.460 cm (height) x 0.750 cm (width) x 0.499 cm (depth). 

Both the Full-size and Mini DisplayPort connectors have the same pin configuration. They also perform the same function of transmitting high-quality digital signals from source to display.

  • DisplayPort Cable VS HDMI Cable:
  •  Are all DisplayPort Cables and HDMI Cables the Same? In this part, we will be looking at the difference between DisplayPort and HDMI cables under the following subheadings; 
  • Connectors
  • Resolution and bandwidth
  • Cable length, and 
  • Audio features.

4.3 Connectors: HDMI VS DisplayPort

HDMI: High Definition Multimedia Interface is capable of carrying audio and video signals from source to display. There are various types of HDMI. They are; Type A, C, D, E. Irrespective of their size, they all have 19 pin configurations excluding type E. It has 29 pins. It is the only type with a locking mechanism, while others depend on friction lock to secure connections.

Applications of HDMI include in most consumer electronics devices, home theatre, computers, and more.  

DisplayPort: DisplayPort is like HDMI in function, but the emphasis is on its ability to work with high-end graphics PCs. It has twenty (20) pins in the configuration. These 20 pins allow for a maximum transfer rate of 8.64 Gbps. It also creates room for additional data transmission with its 1 Mbps for its AUX channel.  Both the Full-size and Mini DisplayPort have a locking feature. This feature ensures a better grip and enhances connectivity.  

4.4 Resolution and Bandwidth: HDMI VS DisplayPort

With a refresh rate of 60Hz in frequency, DisplayPort effectively supports Ultra High-Definition display. For example, these UHD displays come with a resolution of up to 3840 x 2160 pixels. 

Also to note, DisplayPort is compatible with all high-resolution types 8K, Cinema 4K, and more. The maximum bandwidth of DisplayPort is 17.28GBps. 

HDMI has a maximum bandwidth of 10.2 Gbps with a refresh rate of 30Hz. This bandwidth is obviously below that of DisplayPort. Although they can carry signals of the same resolution as DisplayPort, they would be deficient in effectively doing so. The reason is not difficult to understand because they possess a lower refresh rate and bandwidth.

4.5 Cable Length: HDMI VS DisplayPort

There is no specified standard maximum length for HDMI cables. Many HDMI cables are short (within 2 meters long). However, transmitting information over a long distance will require a signal booster. Without a signal booster, the quality of images will be low and may cause a delay. HDMI cables are longer when compared to DisplayPort, about 30m long. 

As said earlier, DisplayPort delivers high resolution (4K) quality over 2m without using a signal booster. It can transmit digital information over 15m long without having to use an active cable. However, this transmission is for a maximum resolution of 1080p. 

4.6 Audio features: HDMI VS DisplayPort

Both HDMI and DisplayPort have many similarities in terms of their audio feature. Recent versions of both cables are compatible with digital audio at 0.192MHz and 24-bit. However, one feature of the HDMI cable stands out compared to DisplayPort cables – Audio Return Channel (ARC).

That is to say. The HDMI cable allows audio signals sent from a display unit to the source device. But, the display unit must have a built-in receiver. This feature helps eliminate the need for additional optical or analog audio cable to serve this purpose.

5. How to Choose the Best Displayport Cable?

Through the article, we explained what DisplayPort was, its importance, and comparison with HDMI. In this chapter, we will guide you through what to consider when picking the best DisplayPort cable. 

5.1 Quality over price

Some people believe that the value of a product or service is directly related to its price. They tell themselves that if a product is costly, then it is highly valued. This belief may be true but certainly not for all cases and products.

For instance, it costs more to manufacture long DisplayPort cables. This high cost will reflect on its purchase price. But we have seen that long cables mostly have less quality. So try not to mistake quality with its price when it comes to DisplayPort cables. Instead, look out for DisplayPort cables that support the high resolution and bandwidth. 

5.2 Compatible connector and cable type

There are two types of DisplayPort cables, so when purchasing, check for its compatibility with your device.

6. Where to buy Custom DisplayPort Cable?

Knowing what to look out for when purchasing DisplayPort cables, we will discuss where to buy them. DisplayPort cables are in some e-commerce stores or any wholesale electronic store.

However, as manufacturers struggle to cut costs, we get to see inferior and repackaged brand products. Some of these manufacturers may not have tested their cables before shipping in haste.

We will like to wrap up the article by speaking on nine significant advantages of custom cable assemblies.

Accuracy and Adaptability

Custom cable assembly provides you will exact cable lengths all fused in a harness. This custom cable assembly saves cost, easy to install and maintain. 

Broader Scope of the Applications of the Custom Cable Assembly

It is nothing new that there are deficiencies present with the old round cables with custom cable assemblies. With a custom cable harness, there is a broader range of applications present. For example, the military requires less weight, less space consumption, and quality custom cable assembly for their mission. All these features are present with custom cable assembly. 

Efficient Performance with Custom Cable Assembly

Another advantage of having a custom cable assembly is that they perform better than standards wires. Custom cables assembly made of quality materials have minimal loss of power during a performance. This loss reduction improves the overall performance of the custom cable assembly. 

Enhanced Functionality

The compact nature that comes with custom cable assembly allows you to do more with less. It provides a more flexible way of interacting with it more, especially for internal wiring. 

Cost-Friendly Solutions

Custom cable assemblies are cheap, meet your project requirement, and last longer in usage. We test all custom cable harnesses to ensure it meets clients’ project specifications before being shipped out to clients. You cannot see this double-check service with standard cables. You will have to carry out a trial and error method, in turn, wasting resources. 

Prototyping with Custom Cable Assemblies

This advantage is something you cannot get from standard cables. But with custom cable assemblies, you get to see a prototype. This prototype gives you a clearer insight into the design and corrections necessary before a mass production occurs.  

Faster Completion of the Projects

As said earlier, custom cable assemblies provide flexibility; it also allows for your project’s swift completion. Imagine having to get many people working with hundreds of wires for your project. This scenario will take much time to complete and resources too. But having a custom assembly alongside an expert, you get to save time and workforce. 

Ability to Scale the Production

In the process of sourcing for numerous standard cables, there might be a problem with their availability. This scarcity can affect your team’s capacity to deliver on projects at hand. With custom cable assembly, you are sure to get your harnesses when due and fit for your project. It is a smart solution.

Take Control of the Project

You are only in control of your project when you have the right tools and custom cable assemblies. You can decide when to finish your project with no fear of uncertainties from your cables.
