Decoding Digital Connections: DisplayPort vs HDMI Explained

Have you ever pondered upon the complexity of cables connecting your devices? Two contenders exist in the visual data transfer world—DisplayPort and HDMI. Not sure what those terms mean? Fear not. In this article, we delve into the dynamics of DisplayPort and HDMI, shedding light on their individual characteristics and differences. We'll also address the question on everyone's mind - which one takes the crown in the DisplayPort vs HDMI tug of war? Settle in, as we guide you through this technological arena, simplifying your understanding and decision-making process.

What is DisplayPort and HDMI port?

DisplayPort is a digital display interface that bridges/connects a video source, such as a computer monitor, with a display device. It allows for the transmission of video, audio, and other forms of data. The Video Electronics Standards Association (VESA) developed this technology, which can support multiple display devices on a single video output. DisplayPort offers high bandwidth transmission, making it easy to handle high-resolution videos. It can support resolutions as high as 8K and has optional support for multi-channel audio.

On the other hand, the High Definition Multimedia Interface (HDMI) is widely used in home entertainment systems and is commonly found on TVs, projectors, and even some high-end monitors. An HDMI connection enables the transmission of uncompressed video data and both compressed and uncompressed digital audio data from a device that is compliant with HDMI standards. The primary advantage of HDMI is its widespread use and backward compatibility with older versions. It supports up to 8K resolution, Dolby TrueHD, and DTS-HD Master Audio sound systems.

Differences between DisplayPort and HDMI port

Audio Support

  • DisplayPort:DisplayPort notably supports multiple audio streams and up to 32 channels of audio. This allows you to send audio to different monitors or applications simultaneously, making it suitable for complex audio setups at workstations or for gaming.
  • HDMI:HDMI ports also provide robust audio support, including the ability to carry uncompressed 7.1 audio channels, as well as high-quality compressed audio. HDMI is popular in home theater setups due to its widespread adoption in consumer electronics like TVs and soundbars.

Resolution and Refresh Rate

  • DisplayPort:DisplayPort is a highly versatile port that supports a wide range of resolutions & refresh rates. DisplayPort 1.4 for example, can support up to 8K resolution at 60Hz, or 4K at 120Hz with HDR10 color. This makes DisplayPort an excellent choice for high-end gaming or professional video editing where high resolution and fast refresh rate are critical.
  • HDMI:HDMI also supports high resolutions, with HDMI 2.1 handling 8K resolution at 60Hz and 4K resolution at 120Hz. However, these capabilities depend on both the HDMI cable and the device being HDMI 2.1 compatible.

Adaptive Sync

  • DisplayPort:DisplayPort 1.2a includes support for VESA's DisplayPort Adaptive-Sync protocol, which is the basis for AMD's FreeSync technology. This means that if you have a FreeSync monitor and a compatible AMD graphics card, you could take advantage of Adaptive-Sync to get smooth, tear-free gaming.
  • HDMI:HDMI has introduced its own adaptive sync technology called HDMI VRR (Variable Refresh Rate) as part of HDMI 2.1. However, it hasn't been as widely adopted as FreeSync. So, even though recent GPUs and gaming consoles offer support, monitor support is not as universal as it is for FreeSync.


  • DisplayPort:DisplayPort can easily be converted to HDMI, DVI, or VGA through passive adapters, making it a highly flexible interface for use with older technology.
  • HDMI:HDMI's compatibility is narrower, primarily focused on audio-visual equipment such as TVs, monitors, game consoles, and sound systems. HDMI tends to be the preferred choice for home entertainment systems due to its widespread adoption in consumer electronics.

Which is better? DisplayPort or HDMI?

Which is better DisplayPort or HDMI? These two popular display interfaces are often used in computers and other electronic devices. Both interfaces have unique strengths, making the "better" choice subjective and mostly dependent on one's specific needs.

DisplayPort is often favored in PC gaming due to its capacity for higher refresh rates and resolution. It even supports AMD's FreeSync and Nvidia's G-Sync technologies, which aid in eliminating screen tearing during gaming.

On the other hand, HDMI is common in home entertainment systems and is preferred for applications that do not demand high refresh rates. HDMI 2.1 now supports 4K at 120Hz, 8K at 60Hz, and its in-built Audio Return Channel (ARC) feature transfers audio to a soundbar, making it the go-to choice for Home Theatres.

So, is DisplayPort better than HDMI? Overall, DisplayPort is largely for high-performance PC gaming, while HDMI is ideal for general entertainment purposes.

So whether you're a hardcore gamer needing ultra-fast refresh rates, a home theatre enthusiast striving for cinematic immersion, or just requiring flawless functionality for your computing tasks - your choice between DisplayPort and HDMI might just be the game changer. Remember, it's not just about what's better generally, it's all about what's better for you.



Here are some commonly asked queries about DisplayPort vs HDMI.


Is It Better to Use DisplayPort or HDMI for Gaming?

The better option between HDMI and DisplayPort can depend on your individual gaming setup. However, DisplayPort generally is the better option for gaming due to its flexibility, higher refresh rates, and support for features such as Adaptive sync, which can significantly enhance your gaming experience.

Should I Use DisplayPort or HDMI for 4K 144Hz?

For 4K gaming at 144Hz, you should ideally use DisplayPort. This is because DisplayPort 1.4 and 2.0 offer more bandwidth than HDMI, making it capable of supporting high-resolution gaming with faster refresh rates such as 4K 144Hz.

Does DisplayPort Make Graphics Better?

DisplayPort does not inherently improve graphics, but it can support higher resolutions, faster refresh rates, and simultaneous audio-video transmission, leading to a higher visual performance given the right conditions. Ultimately, the quality of graphics is contingent upon the capability of your graphics card and monitor specifications.
