Difference between Display Port and HDMI Port

There are two latest video transmission standards in electrical devices i.e., HDMI Port and Display Port.

For digital standards, HDMI was invented in 2002, and DisplayPort was invented in 2006.

While these standards have the same specific goal, i.e., to send high-definition video to your display devices and they have some significant variations between them.

Though they appear similar, they differ from one another in certain ways as follows:

So, let’s begin!

What is the Difference between HDMI Port and Display Port?

What is Display Port?

A digital display interface also known as DisplayPort or DP is a digital display interface.

It was developed by a team of chip and PC that makers and standardized by VESA.

This digital display uses the combination of an external device with a display device like a monitor.

Display Port cables have Higher bandwidths than HDMI cables.

A cable can send more signals simultaneously if the bandwidth is higher and you can connect numerous monitors to your computer.

It’s preferable to use a DisplayPort to connect a display even if you play the game on your PC.

Display Port

Types of Display Port:

A 20-pin connector is used in DisplayPort and there are two types:

1. Full-size DisplayPort Connector:

This is the most common DisplayPort connector at the moment.

It’s a twenty-pin connector that’s typically found on computer displays.

2. Mini DisplayPort Connector:

This twenty-pin connector was created by Apple for their 2008 MacBook Pro, MacBook Air, and Cinema Display models.

Most high-end laptops have a ‘Thunderbolt’ port which is essentially a specialized version of the Mini Display Port that offers higher rates and bandwidth than HDMI.

Display Port versions:

DisplayPort 2.0:

It supports 8K resolutions and it includes 7680×4320 at a refresh rate of 120Hz or 120 frames per second.

A bandwidth of 80Gbps.

DisplayPort 1.4:

It supports up to 7680×4320 (8K) resolutions and a refresh rate of 60Hz (or 60 frames per second) is required.

A bandwidth of 32.4Gbps.

DisplayPort 1.3:

With a resolution of 3840×2160 (4K UHD) provides a refresh rate of 120Hz or 120 frames per second.

The resolution of 7680×4320 (8K) is supported, but at a refresh rate of 30Hz, or 30 frames per second.

The bandwidth of 32.4Gbps.

DisplayPort 1.2:

There is support for resolutions up to 3840×2160 (4K UHD) and a refresh rate of 60Hz (or 60 frames per second).

17,28 Gbps of bandwidth.

What is HDMI Port?

High-Definition Multimedia Interface HDMI is an exclusive interface.

This audio/video interface is specifically designed to transfer uncompressed video signals and data, as well as compressed or uncompressed digital audio data.

HDMI and Audio Return Channel are compatible (ARC) which is helpful if you wish to link a TV to a home theatre system.

The sound from your TV is sent to your home theatre system when you watch TV.

An HDMI cable can be used for an internet connection.

On your laptop, the internet will operate at a maximum speed of 100MB/s, hence Ethernet cable is usually always more sensible.

You can also use HDMI to connect a gaming console, such as the PlayStation 5 or Xbox Series X to your TV or monitor.


Types of HDMI Ports:

HDMI ports currently have a 19-pin configuration in three different types:

1. Type A:

Televisions, projectors, and monitors are the most common HDMI port.

This 19-pin connector sometimes known as Mini HDMI is found in tablets and small laptops.

2. Type D:

Micro HDMI is used in smartphones to reduce space.

Type B and Type E HDMI ports are two different types of HDMI ports that are rarely used.

Type B connectors have 29 pins that can be used for dual-link applications.

The locking mechanism on Type E HDMI connectors prevents it from slipping away under severe vibration of than Display Port.

HDMI Port Versions:

HDMI 2.1:

It supports 3840×2160 resolution @ 120Hz refresh rate or 120 frames per second (4K UHD).

Also, has 7680×4320 (8K) at 60 frames per second, as is a 60Hz refresh rate.

The industry standard for Xbox Series X and PlayStation 5.

It has 46 Gbps of bandwidth.

HDMI 2.0:

It supports for resolutions up to 3840×2160 (4K UHD), and a refresh rate of 60Hz (or 60 frames per second).

It has 18 Gbps of bandwidth.

HDMI 1.4

It supports up to 3840×2160 (4K UHD) resolutions, but refresh rate of 30Hz or 30 frames per second.

When playing 4K video games, this is too low.

10 Gbps of bandwidth.

Frequently Asked Questions:

What is the difference between DisplayPort and HDMI?

DisplayPort is used for computer and peripheral visual connections, whereas HDMI is used for consumer electronics equipment.

What is a DisplayPort?

DisplayPort is a digital display interface, particularly for computer monitors.

What is an HDMI port?

HDMI stands for High Definition Multimedia Interface and is the most frequently used HD signal for transferring both high-definition audio and video over a single cable.

HDMI cables are often pretty small in length than Display Port.

They are used in household televisions and monitors, and the video stream is transferred between closer devices.

For distances up to 2 meters, a passive copper DisplayPort cable can transfer 4k signals with ease but as the distance increases, the capacity decreases.

Passive copper cable can transmit 1080p video at a distance of 15 meters, but DP cable can transmit 2560×1600 HD video up to 20 meters.
