What is a Display Port?

Display Port is primarily used in digital displays such as computer monitors etc. so in this article we will understand the workings of display port and then compare it with another popular interface for digital displays (HDMI), and in the end we will take a look at the advantages and disadvantages of the display port.

What is a Display Port?

A display port is simply known as an interface that can be used for the transmission of data and it is particularly used in computer monitors, just like digital display interfaces the display port also works by efficiently transmitting the data packages from the device which is known as the source device to any of the display devices, for example, the monitor. The display port is developed by the VESA and the main reason for the development of the display port is to replace and come as an enhancement for other display modes such as video graphics array popularly known as VGA and digital visual interface (DVI).

Applications of Display Port

The main application or purpose of using a display port is to connect various types of display devices such as projectors, laptop screens, computer monitors to a video source, the video source can be CPU, etc. apart from using the display port for video and audio transmission, we can no use the display port anywhere else which means that we can no do any type of file transfer that does not include videos or audio.

Working of Display Port

The display port works similarly to the technologies that are used by the Ethernet or USB connectors, it works by supporting multiple amounts of data streams that are independent, since this is an advanced interface it can be used with up to six monitors chained with one another.

For the control and management of the device, there is also an auxiliary channel present in the display port, in the newer version of the display port (version 1.2) the auxiliary channel has been increased from the previous 1 to a massive 720 Mbps which helps in the faster transfer of the data with the USB 2.0.

Difference Between Display Port and HDMI

The HDMI stands for High-Definition Multimedia Interface and it is designed to make sure compatibility is present between the video and the audio devices but only over a single digital interface.

Let’s discuss some of the differences between DisplayPort and the HDMI:

Display Port	HDMI
It is developed by VESA (Video Electronics Standards Association).	Developed by a consortium of electronic manufacturers.
It was released in the year 2006.	It was released in the year 2003.
It supports higher resolution and higher refresh rates as compared to the HDMI.	Initially the HDMI supported lower max resolutions but now it also supports good resolution.
It has higher bandwidth than HDMI.	Newer version of HDMI offers higher bandwidth.
It is widely used in the computer monitors as well as laptops and TVs.	It is widely used in TVs, gaming consoles, home theaters etc.

Advantages of Display Port

Below are some advantages of display port.

• The DisplayPort offers higher bandwidth when we compare it to its connection standards, for example, HDMI, etc.
• This interface also supports MST which stands for (Multi-Stream Transport) which means that multiple displays can be daisy-chained from a single connector.
• Display port supports Adaptive Sync technology.
• This interface can transmit high-definition video as well as audio signals using a single cable.
• Display Ports are constantly getting upgrades and improvements.

Disadvantages of Display Port

Below are some disadvantages of Display Port.

• Display Ports may not be accepted universally like HDMI.
• The cost of the Display port is more.
• The size of the display port connectors is also a bit larger.
• Display port does not natively support Audio Return Channel (ARC) which means that we can not send audio back to the receiver.

Conclusion

In conclusion, the display port offers high-speed and more efficient transmission of the data files which are in audio and video format. Still, when it comes to costs and size metrics then we can say that it is somewhat pricy than the HDMI and other interfaces, so in this article, we have briefly discussed the differences between the display port and HDMI and also looked at the advantages and disadvantages of the display port as well as the working of it.
