What is the difference between DisplayPort and HDMI

After buying a new TV, Projector or Monitor, you might be curious about which audio/video cable you should use. An HDMI port is typically found on a television or monitor.

DP (DisplayPort) connections are also available on many recent models. In this article, we will compare HDMI and DisplayPort and discuss which one to choose for your TV or monitor.

HDMI vs DisplayPort



In recent years, HDMI (High Definition Multimedia Interface) has become a popular interface. It connects all audio and video equipment, including set-top players and TVs.

An alternative to DVI is DisplayPort, a similar interface aimed at computers. Due to its royalty-free nature, DisplayPort is rapidly becoming more popular than HDMI.

There is much more bandwidth available with DisplayPort than with HDMI. HDMI provides 10.2Gbit/s of data transmission, while DisplayPort can achieve 17.28 Gbit/s of data transmission.

Additionally, the auxiliary channel offers 720 Mbit/s. Due to DisplayPort’s customizability, bandwidth can be customized. HDMI, which only provides video, audio, and CEC on one track, cannot compete with DisplayPort.

Instead, DisplayPort is able to adjust its bandwidth to accommodate more than one stream of video or audio, which gives it more flexibility. As a replacement for LVDS, DisplayPort allows laptop displays to be connected directly to the motherboard.

HDMI is not able to handle this. DisplayPort wasn’t initially compatible with DVI or HDMI, but updated guidelines have made it consistent. It is safe to use DisplayPort with almost any device since it can be used with various devices.

A variety of signals can be carried by the AUX channel of the DisplayPort, including Ethernet data and USB 2.0 data. This allows for the integration of ports into displays and integrated devices.

CEC is a remote control channel that allows commands to be sent from one device to another. HDMI is considered to have this advantage. DisplayPort doesn’t come with a CEC channel; however, it can be added as an option to the AUX channel. Read Also:- Best 75 tv under 2000

Key Differences


The DisplayPort interface is more popular than the HDMI interface. An HDMI connection is typically used for connecting televisions, DVD players, and game consoles. DisplayPort can only be found on high-end televisions and computer monitors.

Each standard has its advantages. It all depends on what version of cable you’re using. DisplayPort and HDMI support higher resolutions and have improved features.


A High-Definition Multimedia Interface connects audio sources and digital video sources. A format for transferring audio and video, including high-definition videos, from one device to another without compression.

A single cable can do all of this. It connects the TV and the PC (until the Chromecast came along and changed everything).


While Displayport supports VESA-digital interfaces, DisplayPort does not. You do not need a license to use it. As well as providing a video connection between TVs and PCs, it acts as a video interface. They can be described as being very similar.

The Displayport on my MacBook Air makes it easy to connect monitors. For anyone working from home and needing a keyboard, mouse, and monitor, Displayport is an excellent option. HDMI cables are more expensive than cables because they are not as popular.

HDMI Versions

It was released towards the close of 2017 as HDMI 2.1, and it is the latest version of HDMI. HDMI 2.0b is the most popular version used in TVs and computer monitors.

  • The HDMI 2.1 interface supports resolutions of up to 10K and dynamic HDR (High dynamic range) as well as an enhanced audio return channel (eARC).
  • The HDMI 2.0 interface supports resolutions up to 4K at 60Hz. HDR is also supported by later versions of HDMI (2.0a, 2.0b).

DisplayPort Versions

A new version of DisplayPort 2.0 came out in 2019 and is the most recent standard. A new version of DisplayPort was released in 2019.

  • 144Hz 144K DisplayPort 2.0 can support two 4K monitors at full resolution at a rate of 16K. G-Sync and FreeSync are 3D sync technologies supported by this product.
  • A display port supporting DisplayPort 1.4a has a resolution of up to 8K and 60Hz HDR.

It’s crucial to keep in mind that HDMI 2.1 and DP 2.0 are still relatively new standards. The majority of televisions and monitors do not support these new standards.  It is possible to use an HDMI2.1 cable with a TV that supports HDMI 2.0, as both are compatible.

Different Resolution and Framerate

New versions of the standards are being produced every day for both DisplayPort and HDMI. As video technology advances, so does the standard.

However, this doesn’t mean that your new display will comply with the latest standard. The value of a 4K port is not worth the extra cost if the resolution of your display is 1080p or lower. Therefore, so long as you follow the minimum standards for display, the cable should be compatible.

You cannot use your 4K cable with your 1080p monitor. In technical terms, High-Speed HDMI certification refers to HDMI 2.0. Providing a 4K resolution at 60 Hz, it offers a 4:3 aspect ratio.

There are 14.4 Gbps of bandwidth available. The new HDMI 2.1 standard is slightly better than the previous one. It supports a 4K resolution at 120Hz. A gaming PC with this amount of RAM would be sufficient. Additionally, it supports an 8K resolution at 60Hz and a bandwidth of 77.4Gbps.

Although this standard is not widely used, it can be found on very expensive AV equipment. With the growth of VR entertainment, you’ll see more HDMI 2.1 devices.

For modern DisplayPorts, version 1.2 is the most commonly used version. It supports 4K video at a distance of less than 2m and a 60Hz frame rate. Almost all 3D video formats are supported, and a bandwidth of 17.28 Gbps is available.

The latest version of DisplayPort is 1.4. The resolution is 5120×2800 at a 60Hz frame rate, and the bandwidth is 25.92 Gbps. DisplayPort 1.4 was not widely used at the time this article was written.

In recent years, display displays have become more detailed, resulting in a growing demand for DisplayPort 1.4 cabling.

When is HDMI the best option?

HDMI supports Audio Return Channel. This feature is helpful if you wish to connect your TV to a home theater set. The sound from your TV is sent to your home cinema system when you watch it.

An HDMI cable can be used to connect to the internet. You can connect your laptop to the internet using an HDMI cable that supports this function.

Your laptop will be able to receive an internet speed of up to 100MB/s. An Ethernet cable is recommended in almost all situations.

An HDMI cable can be used to connect a game console such as the PlayStation 5 or Xbox Series X, or your TV or monitor.

When is DisplayPort the best option?

DisplayPort cables offer more bandwidth than HDMI cables. High-bandwidth cables can transmit multiple signals simultaneously.

When you need to connect more than one monitor to your computer, this feature is especially useful. When it comes to connecting a computer to a monitor, DisplayPort cables are better than USB cables.

Picture Quality and Bandwidth

The DisplayPort 1.4a standard is still the most popular DisplayPort version, even though it’s a few years old. It supports 8K UHD (7680×4320) and 4K UHD (3840×2160), along with HDR.

DisplayPort 2.0 is currently not supported by any devices, despite its official release. Before it happens, some time will pass. In comparison with 1.4a, this difference is quite significant.

A maximum bandwidth of 77.4 Gbps (30.92 Gbps) is available, up to 144Hz 4K High Dynamic Range resolutions, and 60Hz 16K resolutions (15360 x 8460 pixels).

In addition to being backward compatible, it is also feature-complete. DisplayPort has one drawback: it cannot support Ethernet data and does not support audio returns. The product can output multiple video signals, allowing it to display various screens at the same time.

HDMI 2.0b, currently one of the most popular versions, supports 4K resolution but only operates at 60Hz. With HDMI 2.1, a 4K display refresh rate can be increased up to 120Hz, and the bandwidth up to 18Gbps. There is no widespread market support for 10K, although the latest standard does.

HDMI provides return audio, whereas DisplayPort does not. Alternatively, you can purchase versions that include 100Mbps Ethernet. Using the former allows you to upstream audio to an AV receiver if you do not want the TV’s built-in speakers to sound.

In addition, Consumer Electronics Control, which allows a device to be controlled using a single remote control, was supported. A CEC-enabled device must support this, however.

FAQ;- (Frequently Asked Questions)

What’s better, HDMI or DisplayPort?

Depending on the situation. The DisplayPort cable is the best choice for multiple display connections when you need more bandwidth than HDMI. HDMI is the best choice if you need to connect your TV to your home cinema system.

HDMI can be used as DisplayPort?
Passive adapters are needed to convert DP signals to HDMI.

Do I choose HDMI or DisplayPort144 Hz?

DisplayPorts are ideal for achieving 144 Hz. In comparison to HDMI, it is a much stronger signal. There are DP versions with 144Hz and 1080p capabilities.

Both the DP 1.0 or 1.2a versions can output 1440p at 1.2 and 1.2a versions, while the DP 1.3 can produce resolutions of 4K at 120Hz. DSC is a technology used by all three versions of the application.

Final thoughts: Which is the best display cable for gaming?

Both HDMI and DisplayPort each have their strengths and weaknesses. Gaming is a different matter. Your choice of cable will be determined by the platform on which you play.

Neither PS5 nor Xbox Series X supports DisplayPort, but both devices support HDMI 2.1. When it comes to console gaming, HDMI is by far the best choice (though you will still need a 4K TV and monitor that support HDMI 2.0 to enjoy the full advantages). In PCs, DisplayPort outlets are more common.

If you build your gaming computer, make sure it has one. DisplayPort 2.0 will provide more benefits than HDMI 2.1, and it will be easier to see on a monitor with a high refresh rate.

DisplayPort 2.0 includes a locking mechanism that allows you to attach the cable to your monitor securely. You should avoid running the cable across your room if it’s dangerous.

When your cables are contained, however, they can be an asset. If you are interested in VR, you may need a PC with a DisplayPort interface.

It would help if you chose a VR headset based on your needs. Sadly, HDMI connections aren’t supported by the Oculus Rift S or Valve Index.
