We find these DMI and DisplayPort cables everywhere but have you ever thought about what is the origin of DisplayPort cables and how DisplayPort cables are manufactured? For better understanding, we have divided the guide into chapters, and each chapter is going to discuss a specific point about DisplayPort.

DisplayPort and Mini DisplayPort

Chapter 1: What is Display Port Cable?

Manufacturers and brands are continuously working on the betterment and improvement of the technologies of their products. A few years ago, most of the devices were using VGA cables and then brands introduced smart display cables like HDMI cables and DisplayPort cables.

DisplayPort is a digital method to transmit video and audio data from the source to the display. There are some specific cables that we use for these types of display options, and those cables are the DisplayPort cables.

Sony, Phillip, and Maxell are some of the famous brands that introduced DisplayPort to their devices according to the Video Electronics Standards Association. Most of the monitors, computers and other display devices are using DisplayPort cables for the transmission of data from source to the monitor, LCD or any other display device. 

The essential purpose of the DisplayPort cables was to replace the old methods and adapters with relatively newer and smarter methods. Many devices that were using VGA, DVI, and other early display options are now using DisplayPort cables for the transmission.

Where do we use Display Port Cables?

This chapter will cover the basics of DisplayPort cables that every reader must know. Most of the people may think that this guide is not for them but believe me. We all have electronic devices in our homes and offices, and things can get messy anytime with your device. If something is wrong with your adaptor or display cable, you should be able to buy the right wire on your own. You cannot hire a professional to take care of even every small cable. If something goes wrong with your DisplayPort, you will be able to make the right purchase after reading this guide about DisplayPort cables.

So, have you ever noticed that most of the display devices use smart cables, but some are still using thick and traditional pin adapter? Let’s have a look at which devices are using DisplayPort cables these days. Most of the high-resolution display devices use DisplayPort cables, and some other devices use DisplayPort cables like:

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

If you have DisplayPort cables and want to use any different port with these DisplayPort cables. There are many adapters and extension available that you can use to convert HDMI to DisplayPort.

History of Display Port Cables

VGA cables were great for standard display transmission. However, with technology improvement, the devices needed better display cables that can ensure higher resolution with fewer pins. Manufacturers introduced DisplayPort cables to the market as the first display interface that was using packetized data transmission. The same packetized data transmission technology is available in USB ports, Ethernet and PCI express. The data transmission is carried out by using small packets of the data, and these little packets are the micro packets in terms of technology.

Most of the display methods were able to carry video data, and for audio data, the different interface was there in the devices. Moreover, to improve the quality of the display and audio data, DisplayPort cables can carry both at the same time.

Chapter 2: DisplayPort Cable and Connectors Overview

In this chapter, we are going to talk about the technical stuff about DisplayPort cables. There are different types of connectors and cables for DisplayPort. We have divided these points into various sub-headings for better understanding.

Features and compatibility

All DisplayPort devices support DisplayPort cables. The version or the certification of the DisplayPort does not affect the compatibility of the DisplayPort cable.

Mini DisplayPort and DisplayPort cables

All the available functions and features of any DisplayPort device will be operable with all DisplayPort cables. The cable design, wiring and the layout of the pins are approximately the same for all the DisplayPort connectors, so all the DisplayPort cables support features like video, audio, and data transmission. The transmission speed for different wires can vary depending upon the quality and length of the cable.

Cable length

There are no limitations for the maximum length of the DisplayPort cables. There are resolution limitations that all the wires must meet. If we cross the length of 2 meters for any DisplayPort cable, the quality can vary.

Certification and cable bandwidth

Although DisplayPort cables are the top choice for high-resolution transmission but not all the wires, deliver the high quality. The manufacturers must submit the DisplayPort cable to VESA for the certification depending upon the quality of the cable. The bandwidth values can also vary depending upon the quality of the cable.

Connectors and pin configuration

There are two types of connectors for DisplayPort cables.

  • Full-sized connector
  • Mini DisplayPort connector

The DisplayPort connectors can vary in terms of physical shape and design. The functions remain the same for all types of connectors regardless of their design and size. If you use a mini connector, it will not affect the features or quality of the transmission.

Here are some main connectors and pin configurations for DisplayPort cables.

  • 12 pins for the main link
  • One pin for HPD
  • Three pins for the auxiliary channel
  • Two additional ground pins
  • Two pins for power

Chapter 3: Display Port Cable vs. HDMI Cable

VGA cable has become the story of the past. Although many devices are still using VGA cables. If we compare the VGA cables with HDMI or DisplayPort cables, we will see that most of the devices don’t support VGA cables these days. So, the primary race is between DisplayPort cables and HDMI cables. If you want to know more about VGA cables and how to choose the right VGA cable, you can see other articles on our site.

In this guide, we are going to compare HDMI with DisplayPort cables. Which display option is better and which method provided better graphics. We are going to go through the entire question that may arise in the reader’s mind. 


In 2003, top manufacturers decided to introduce a new display interface for their devices. Brands like Sony, Phillip, and Panasonic introduced the HDMI display adapters to the market. Today, most of the devices use HDMI as standard display method.


After a few years of HDMI, brands decided to introduce another improved replacement for DVI and VGA cables. So in 2006, DisplayPort replaced VGA and DVI display interfaces.

In this chapter, we are going to compare HDMI and DisplayPort. We will see which option is better and how you can make the right choice for your purchase.

1. Connectors: HDMI vs. DisplayPort

HDMI: Generally, HDMI connectors come with 19 pins, and there are five different shapes of these HDMI cables. Out of 5, only three shaped are widely available in the market, and you might have seen one of these three great shapes. There are connectors like Type a, Type C and Type D.

There is another type of HDMI connectors that comes with 29 pins. This type of HDMI is rarely seen in home applications. This type of HDMI connector mostly comes in the device that uses dual-link applications.

Type E of HDMI connectors have locking tab, and this type of HDMI cables is suitable for automobile applications where we need a firm grip on the devices.

DisplayPort: Our main focus of this article is DisplayPort cables, and the DisplayPort connector generally uses 20 pins. There are two common sizes available for DisplayPort connectors. The standard DisplayPort connector is the normal-sized connector, and many other brands are manufacturing these connectors, but there is another mini version too.

The mini DisplayPort connectors are the product of Apple and called DisplayPort. All the DisplayPort connectors have some locking feature that allows better grip and connectivity. This feature provides better security against accidental disconnection. This feature is available in most of the devices, but the original description of the DisplayPort connectors does not demand this feature.

2. Resolution and Bandwidth: HDMI vs. DisplayPort

Most of the DisplayPort cables support the UHD display that has the resolution of up to 3840 x 2160 pixels. The refresh rate for the resolution is 60 HZ. This resolution is also known as 4K, but the movie industry has a different resolution for 4K display. DisplayPort cables support all types of high-resolution video formats including 3-D too. The value of maximum bandwidth for DisplayPort is 17.28 GBps.

Most commonly available HDMI supports the resolution that is same as the DisplayPort cable. However, for HDMI, the refresh rate is lower than DisplayPort, and the refresh rate for HDMI is 30 HZ. The value of maximum bandwidth is 10.2 GBps, and that is also lower than the DisplayPort.

3.Cable Length: HDMI vs. DisplayPort

There are many different standards for HDMI cables that are available in the market. High-Speed certification is the typically possible standard that is available in the market. Due to quality differences, there are many low-quality cables too that can cost less money but don’t deliver the desired results. You can face glitches and artifacts with these cables that can disturb the video quality.

Display cable regular length for home useThere is no definite standard for the maximum length of HDMI cables. The standards generally focus on the quality, and you can derive the recommended length from there. Most of the HDMI cables are very short in length. In the case of projectors, the length of the HDMI cable can vary from short to 2 meters. If you want to use HDMI for long-distance, you can use a signal booster that doesn’t lower the quality of the transmission. You must know that you can use CAT 5 and CAT 6 cables too to carry the HDMI signals.

The resolution of the DisplayPort cable can vary for different lengths of the wire. If you want to use DisplayPort cables for up to 15 meters, you can use the 1080p resolution only.  

Display Port Cable- First choice

For most of the cases, HDMI seems like a decent choice, but if you want to enjoy high resolution without affecting the quality, DisplayPort cables must be your first choice. There are many great features of DisplayPort that are better than HDMI, so there is no reason not to make DisplayPort your first choice.

What kind of cable do you need?

The perfect DisplayPort cable must be within your budget limits. Moreover, if you want to use it for high-resolution devices like UHD screens, make sure that you are buying the right DisplayPort cable. So that can support your desired resolution.

It would help if you also considered the distance between the source and the display device to buy the perfect DisplayPort cable. If you purchase the extra-long cord, it can also disturb the video quality of the transmission. 

Chapter 4: How to choose perfect Display Port Cable?

Choosing the right DisplayPort cable is more comfortable than said. In the above chapters, we have covered everything that you need to know about the working, types, and sizes of the DisplayPort cables. In this chapter, we will focus on some tips that you need to keep in mind while buying DisplayPort cables.

Select the right DisplayPort cable for your project

Price of the cable is not the quality standard

Many users think that if something is expensive, it must be good. However, this does not work for DisplayPort cables. The quality of the DisplayPort cable does not depend upon the price. If you want to buy a long DisplayPort cable, the price is going to be high. However, it does not mean that the quality will also be useful for that cable.

If you want to determine the quality of the DisplayPort cable, you should look for supported resolution and the bandwidth instead of price.

Connector and cable type

As you know that there are different types of connectors for DisplayPort cable, so you must know which kind of cable you are going to buy for the right device. If your device is using a mini connector, make sure that you are purchasing the right DisplayPort cable that supports mini connectors.
