Does DisplayPort Carry Audio?


Yes, DisplayPort does carry audio and video. DisplayPort transmits audio with high clarity and quality making it the perfect choice for those aspiring to achieve great sound from their setup.

Benefits of DisplayPort

With DisplayPort, you can get the highest resolution and refresh rate available for your device! It supports 8K resolutions for external displays, more than double what most video and audio devices support with their 4K capabilities. This makes it perfect for gaming without lags or any other issues.

You’ll also be able to use up to 1080p resolution on version 1.0 while 1440p and higher are supported by version 1.2 and forward. The best part is that its maximum refresh rate won’t depend on the display ports, so if you have HDMI 2.1 and DP 1.0, the DP will provide the best performance possible!

On top of all this, using a DisplayPort cable doesn’t come with any technical limitations at all – giving you ultimate control over how your screen looks while eliminating disruptions in sound quality too!

DisplayPort Audio Transmission Improvements

With its increasing capabilities, DisplayPort has improved audio transmission over time. DisplayPort 1.0 and 1.1 had relatively limited audio specifications, with a maximum sample rate of 192 kHz, 24-bit sample size and 8 channels. Version 1.2 and 1.2a increased the sample rate to 768 kHz while keeping the other parameters unchanged. DisplayPort 1.3 made no changes to audio but version 1.4 saw major improvements with a maximum sample rate of 1536kHz and 32 supported channels as seen in the following table:

Version Max Sample Rate (kHz) Sample Size (bits) Max Channels
DP1.0/1.1 192 24 8
DP1.2/1.2a 768 24 8
DP1.3 N/A N/A N/A
DP1.4 1536 24 32

This greatly enhances user experience by providing more immersive sound quality for multimedia applications like gaming or home theatre systems without compromising on bandwidth availability or resolution support requirements from peripheral devices connected via DisplayPort interface standards . From here we can move on to discuss how to use these improved audio transmission capabilities of modern DisplayPort interfaces for various multimedia applications.

Our post about DisplayPort 1.2 vs 1.4 explains the differences in detail.

Types of DisplayPort

There are two types of DisplayPort: standard and mini. Both types offer similar resolution. The standard cable is usually sold by consumer electronics stores, while the mini is best used for smaller devices and Apple electronics, as they are highly compatible.

Both types can display equal level resolutions, yet the mini has restricted bandwidth and audio output compared to the standard cable:

  • Bandwidth:
  • Standard – High Capacity
  • Mini – Limited Capacity
  • Audio Output:
  • Standard – Full Range of Audio Out Options
  • Mini – Restricted Audio Out Options
  • Resolution:
  • Standard & Mini – Equal Level Resolutions

It should depend on the available port, but if both types of display ports are available, then go for the standard DisplayPort for higher compatibility with newer versions.

With this knowledge in mind, it’s time to move onto products that support DisplayPort.

Products that Support DisplayPort

You can find a variety of products that support DisplayPort, from Google Chromebook Pixel to Macbooks.

Product Manufacturer  
Google Chromebook Pixel Google
Microsoft Surface Pro with Windows 8 Microsoft
Dell XPS 13 Ultrabook Dell
Lenovo Thinkpad X1 Carbon Ultrabook Lenovo
MacBooks (multiple versions) Apple

All these devices provide high-speed audio and video interface, allowing for better resolution. This is why many manufacturers are choosing DisplayPort over other digital interfaces such as VGA, DVI, or even HDMI cables. The advantage of DisplayPort lies in the fact it supports higher resolutions than its predecessors. As a result, manufacturers are phasing out VGA and investing in DisplayPort technology instead. With this move towards embracing modern technology, users will be able to enjoy improved performance without compromising on quality. Now let’s explore how DisplayPort differs from HDMI when it comes to audio capabilities.

DisplayPort vs HDMI Audio

Both DisplayPort and HDMI offer high-quality audio, but there are some differences between them.

The latest version of HDMI supports up to 48 Gbps of bandwidth, whereas DisplayPort 2.0 can support 77 Gbps. This excess capacity gives DisplayPort an edge when it comes to transmitting audio signals over longer distances without any signal interference. Additionally, with the increasing demand for 8K resolutions, only DisplayPort is capable of supporting this resolution since its higher bandwidth allows for more data to be transmitted at once.

When considering which type of connector is better for audio transmission, it really depends on what kind of setup you’re running and what your budget is.

If you need a long-distance connection or require 8K resolution, then the increased bandwidth offered by DisplayPort will make it a better choice than HDMI. However, if you don’t need these features or have a limited budget then either option should work fine for your needs with no major compromises in sound quality compared to the other cable type.

Which is Better?

It’s hard to say which is better, DisplayPort or HDMI, as it depends on the setup and budget. DisplayPort has a higher bitrate than HDMI and can transmit data faster. It also supports up to 8K resolution and refresh rates of 240Hz compared to 4K at 60Hz with HDMI. Furthermore, it supports more audio stream formats such as Dolby Atmos and DTS:X for surround sound systems.

However, if you are using older devices that don’t have a DisplayPort connection, then you may need an adapter or converter in order to use it. So depending on your device compatibility and budget, either one could be a suitable cable for your needs.

Moving forward, let’s take a look at how DisplayPort audio transmission has been improved over time.

How to Use DisplayPort Audio

To get the best audio experience, you’ll need to use the improved DisplayPort audio transmission capabilities.

First, make sure that your device is compatible with DisplayPort audio output; check your manufacturer’s specifications if you’re unsure.

Then, purchase a compatible DisplayPort cable and connect it from your device to a supported display with built-in speakers or a headphone output. Alternatively, you can also use an adapter to convert Mini DisplayPort connectors or Thunderbolt 3 ports into full-size DisplayPort connections.

For Windows users, search for ‘Sound Settings’ in the search box and select the correct device from the Output devices dropdown menu. If you still don’t hear any sound coming through, try updating drivers for your graphics card and system chipset.

Finally to ensure success:

  • Use only certified cables and adapters that are compliant with DisplayPort standards
  • Avoid using too many devices on one port as this may cause interference
  • Make sure all hardware components have been properly installed before attempting to transmit audio over DisplayPort

With these tips in mind, you’ll be able to enjoy high-quality digital audio over your DisplayPort connection!
