Does this technical verbiage make you nervous? Don’t sweat if you’re asking all of these questions; we’ve felt your pain!

We’ll go over all there is to know about DisplayPort and HDMI, as well as the differences between the two. Keep reading to dispel any misunderstandings. Let’s start by understanding the distinctions between DisplayPort and HDMI.


Laptops and televisions both have DisplayPort ports. DisplayPort is a connector that connects a device to a display, according to the simplest definition.

This digital interface was recently defined by VESA, or the Video Electronics Standards Association. It consists of a narrow cable with a little connection on one side. The cable may be as long as 50 feet. It was initially used in 2007 and has since become a standard feature on all modern computers.

The Mac PCs, on the other hand, employ a Thunderbolt version known as Mini DisplayPort. Because it is utilized directly on the laptop, the DisplayPort used in laptops and televisions is known as an Embedded DisplayPort or eDP. This connects the motherboard of the laptop. The motherboard of the laptop is connected to the LCD through this cable. The name for this connector on televisions is Internal DisplayPort or IDP. A Display Port’s principal function is to send visual signals to a monitor.

It can, however, accommodate up to eight audio channels. These channels have the following characteristics:

If the speakers are built into the monitors, there is no need for an additional connection to connect the DisplayPort for sending digital audio data. and

The efficiency of a DisplayPort comes from the fact that data is sent in tiny packets and hence is often regarded as superior to HDMI, VGA, and other display interfaces. The DisplayPort can function considerably more smoothly because of the construction of these packets. Data and signal transmission are considerably better in these DisplayPort connections than in other interfaces that have a dedicated physical pin for particular functions. Each of these micro packets has its clock synchronization.

Apart from that, the DisplayPort allows thinner monitors to be connected. This is because most displays use the Direct Drive interface, which reduces the need for complex hardware.

The present success of DisplayPort is due to its design, as well as its useful features and support capabilities:

  • Its MST (Magnetic Secure Transmission) innovation may drive as many as six displays in a daisy chain, and it supports numerous channels and independent data streams.
  • It has an auxiliary channel that allows it to monitor and control devices.
  • It supports the DPCP (DisplayPort Content Protection) system, which is an optional but comparable system.
  • It complies with HDMI’s HDCP (High-bandwidth Digital Content Protection) standard.

There are numerous distinct models of DP, each with its unique set of features that separate it from the alternatives.

For starters, the auxiliary channel capacity of the Version 1.2 DP has been increased from 1 to 720 Mbps. It can transfer both video and USB 2.0 files thanks to this standard.

At different times, several types of DPs were released, allowing for a range of resolutions and displays. Consider the following illustration:

  • Version 1.3 was released in 2014, with a bandwidth of 32.4 Mbps and a resolution of 7680 x 4320 or 8K.
  • Version 1.2a was released in 2010 and featured adaptive synchronization technology for the first time.
  • Version 1.2, released in 2009, had a bandwidth of 17.28 Mbps and supported 4096 x 2160 or 4K resolution, while Version 1.1, released in 2007, had a bandwidth of 8.64 Mbps and allowed 2560 x 1600 or 1K resolution.
  • Version 1.2, released in 2009, had a bandwidth of 17.28 Mbps and supported 4096 x 2160 or 4K resolution, while Version 1.1, released in 2007, had a bandwidth of 8.64 Mbps and allowed 2560 x 1600 or 1K resolution.
  • There’s also Version 1.4 DP, which was published in 2016 and is essentially an update to the prior three versions.



On the other side, the HDMI, or High-Definition Multimedia Interface, is a proprietary interface.

This audio/video interface was designed to transmit both compressed and uncompressed digital audio data, as well as uncompressed video signals and metadata.

To utilize the HDMI port, you’ll need an HDMI-compliant root unit. This might be the case:

  • A video projector
  • A digital TV
  • An HDMI compatible monitor of a computer
  • A display controller
  • A digital audio system

In an ideal world, the HDMI connector would serve as a contemporary replacement for both conventional and analog video.

In terms of design and architecture, the HDMI complies with the EIA or CEA 861 standards. A clear framework exists that explains a variety of objects, such as:

  • The auxiliary data
  • The waveforms
  • Transfer of compressed and uncompressed digital LPCM audio data
  • The video formats and VESA EDID implementations

The Digital Visual Interface, or DVI, is used to transmit the CEA 861 signals. Because these signals are electrically comparable, there is no need to interpret them.

This ensures that no messages or data are lost, which might degrade video quality. It works nicely while utilizing a DVI-to-HDMI converter.

The Consumer Electronics Control function is another important aspect of HDMI.

This not only makes system management easier but also makes managing various devices easier. A single portable remote control can control all of these devices.

Over the years, there have also been numerous versions of HDMI created and utilized, just as there have been several variants of Display port.

Because of this remarkable technological breakthrough, they may all utilize the same connection and cable.

The following are noteworthy additions and modifications to the variations over time.

  • Enhanced video and audio capabilities
  • Improved efficiency
  • Support for higher resolutions
  • Increased color spaces

There are a variety of extra sophisticated capabilities in the later versions of HDMI, such as-

  • 3D compatibility
  • CEC or Consumer Electronics Control extensions
  • Ethernet data connection

Even though production began in 2003, HDMI was first utilized in consumer HDTVs in 2004. It was used in digital still cameras and camcorders before and after 2006.

The HDMI standards and capabilities encompass everything from signals to protocols, from electrical interfaces to mechanical characteristics. The HDMI 1.3 version features a 340 MHz pixel clock rate, which allows for greater resolution.

HDMI 1.0 has a peak pixel clock rate of 165 MHz and offers 1080p resolution. WUXGA or 1920 1200 resolutions are also supported at 60 Hz.

Using a single digital connection, WQXGA or a resolution of 2560 x 1600 pixels is also possible. There are two sorts of HDMI connections, which might alter depending on the situation. Type B dual-link and Type A, C, or D single-link are the options.

Furthermore, single-link HDMI connections can have video pixel rates ranging from 25 to 340 MHz, whilst dual-link HDMI connectors can still have video pixel rates ranging from 25 to 680 MHz

In terms of visual formats and HDMI compatibility, it operates at a frequency of fewer than 25 MHz in actuality, but 13.5 MHz according to the 480i/NTSC standard.

This is because visual signals are sent via the pixel repeat method. If visual quality is the primary consideration, there are no significant differences between a DisplayPort and an HDMI. On the other side, newer DP implementations may allow for greater bandwidth and full display resolution.

Although DisplayPort and HDMI are two different standards, they are both used to transmit video and audio information from a source to a display. As a result, they’re both made to accomplish the same thing.

Apart from the ostensibly unique connections, there are several variations between the two. To tell the distinction between the parties, you’ll have to go far further than the differences in versions of the two connection types.

You’ll need to understand the distinctions between standards, cable, resolution, bandwidth, and other factors. With this information, you’ll be able to simply convert DP signals to HDMI utilizing a passive adaptor, even though the reverse is not feasible.

While DisplayPort and HDMI are two distinct standards, they both transfer video and audio from a source to a display. As a consequence, they’re forced to do the identical duty.

There is a lot of difference between the two, aside from the distinct connections. You’ll have to go beyond the variations in models of the two connection kinds to tell the difference between the two.

You’ll have to know the differences in standards, cable, resolution, bandwidth, and other considerations. With this knowledge, you’ll be able to convert DP signals to HDMI utilizing a passive adapter in no time.

Let’s take a closer look at the differences between DisplayPort and HDMI and go deeper into the details-

DisplayPort vs. HDMI: What’s the Variance?

There are 13 significant distinctions between DisplayPort and HDMI that most people are aware of. Let’s start with the differences in connections between these two-

Difference in usage

DP 1.2 is used for video wall displays. However, the newest DP 2.0 claims to support 10,240 x 4320 resolutions thanks to its very high bandwidth of 77.4 Gbps, although there are presently no models that employ this variation.

In digital cinema, only HDMI connections and genuine 4K PCs are utilized. This is owing to the 4K UHD resolution, 14.4 Gbps bandwidth, and 60 Hz refresh rate of the upgraded HDMI 2.0 version. 4K resolution at 120 frames per second and 8K resolution at 60 frames per second are supported via HDMI 2.1. Although it is not particularly widespread, this variation is utilized in some of the higher-end models.

The difference in types and shapes

There are just two DisplayPort sizes to select from when it comes to DisplayPort. The first one is the regular DisplayPort, while the second is Apple’s Mini DisplayPort, which is a scaled-down counterpart of the larger one and is identical to the Thunderbolt model.

There are five distinct types of HDMI ports, although only three of them are frequently utilized. Type A, or normal HDMI, is commonly found in televisions, computers, and projectors, while Type C, or mini HDMI, is commonly found in laptops and tablets, and Type D, or micro HDMI, is commonly found in smartphones and tablets.

Difference in connectors

The DisplayPort connections contain 20 pins, enabling audio and visual signals to be sent simultaneously.

The configuration of the HDMI connection typically employs 19 pins to transfer data and operations.

Difference in origination

In 2006, a different group of computer and processor manufacturers established the DP.

HDMI, or High-Definition Multimedia Interface, was developed and introduced in 2003 by a group of major monitor manufacturers, including Philips, Panasonic, Sony, and Toshiba.

Difference in objectives

The launch of DisplayPort was primarily an endeavor to enhance and replace the earlier VGA and DVI standards, with a focus on professional IT equipment and computer displays to gain market share in the data-centric sectors.

In contrast, the HDMI connection was designed specifically for usage in image-driven devices like televisions, computers, and projectors.

Difference in bandwidth

The maximum bandwidth of HDMI 1.4 is just 10.20 Gbps. It is useful to link to the version number while evaluating the port’s usefulness.

The maximum bandwidth that the DP 1.2 version and cable can send is 17.28 Gbps. DisplayPort 1.4 supports 5120 x 2800 resolutions at 60 frames per second and has a bandwidth of 25.92 Gbps. This version is becoming exceptionally productive with each successive day.

Cable length

The HDMI specification does not specify a specific cable length. It is primarily concerned with efficiency standards, which define the cable length, which is often shorter than DP cables.

The cable length for passive copper DisplayPort cables is usually two meters. Active copper DP cables, on the other hand, may reach up to 20 meters in length.

Use for longer distances

You’ll need an active copper DP cable to maintain a resolution of 2560 x 1600 across a distance of 20 meters. If the resolution is limited to 1080p, a passive copper DP cable can traverse a distance of up to 15 meters. Only fiber lines can transport data over longer distances.

You’ll need an active cable or a signal amplifier to boost the signal unless you try to use the HDMI port for a longer connection. This would make it easier to install CAT 5 or CAT 6 cables up to 50 meters long, coaxial cables up to 90 meters long, and fiber optic cables over 100 meters long.

Commonly used versions

Apart from popular 3D file formats, the most prevalent DisplayPort variation today is DP 1.2, which supports video resolutions of 3840 x 2160 pixels or 4K UHD at 60 frames per second.

In comparison, the HDMI 1.4 protocol is the most frequently used and covers all Full HD visualization equipment. It has the same resolution as the DisplayPort 1.2 version but at a lower frame rate of 30 frames per second.

The cable standards

Ethernet signals are not allowed to be sent via the DP standard. Additionally, there will be no audible response signal. Using different adapters, the DisplayPort may connect to a broad range of display standards, including VGA, HDMI, and single-link DVI.

HDMI cables are available in several different specifications. The high-speed HDMI certification is the most often utilized. Regrettably, glitches and artifacts prevent this cable from meeting the necessary standard in low-end consumer products.

Multiple display support

One of the most significant differences between DP and HDMI is the possibility of multiple views. Because the HDMI port is unable to provide help, it is inappropriate for practitioners who operate with a particularly big display.

A DP can handle many monitors at the same time using a single DisplayPort interface and cable. It can broadcast films with a resolution of 1920 x 1200 to four or even six displays to create a projection screen.

The difference in versions and resolution support

The DisplayPort and HDMI versions, as well as the specs for each of these variants, vary.

HDMI 2.1 supports 4K UHD at 120 HZ refresh and 8K resolution at 60 Hz refresh, 2.0 supports 4K UHD at 60 Hz refresh, while HDMI 1.4 only supports 4K UHD at 30 Hz frequency.

DP 2.0 will enable resolutions up to and including 8K (7680 x 4320), DP 1.4 up to 8K, DP 1.3 4K UHD and 8K resolution at a decreased refresh rate and frames per second, and DisplayPort 1.2 4K UHD at a higher refresh rate and frames per second.

Audio support features

The DisplayPort supports up to eight digital audio streams at up to 24 bits and 192 kHz on a single path.

Except for ARC (Audio Return Channel), the HDMI connection may take eight digital audio channels at the same rate as the USB port. This guarantees that audio signals are delivered to the TV set from the source unit or AV receiver, as well as in other ways.

Differences Between DisplayPort and HDMI FAQ

That was all there was to it when it came to the distinctions between DisplayPort and HDMI. We hope you found this useful and learned a lot from it.

We’ve created a list of the most frequently asked questions to assist clear up any residual uncertainties.

You can convert DP signals to HDMI with a passive converter, but you’ll need one.

To obtain 144 Hz, it’s preferable to utilize a DisplayPort. This is due to the fact that it is more competent than HDMI. A 144Hz 1080p display is generated by the DP 1.0 or 1.1a. The 1.2 or 1.2a versions will accomplish the same at 1440p using DSC or Display Stream Compression technology, the 1.3 version at 120 Hz, and the 1.4 version at 4K resolution.

It’s a point of dispute. A DisplayPort is the way to go if you need more bandwidth than HDMI and wish to connect several monitors with a single cable. HDMI is the ideal choice if you want to connect your TV to your home theater system, use your internet connection, and connect a gaming console to your laptop or TV. Let’s go on to the conclusion since most of your questions have been answered.
