When comparing HDMI vs DisplayPort, it is necessary to look into every aspect you can compare from both sides. Here are some of the major differences you will notice:

HDMI vs DisplayPort: Maximum Bandwidth

Bandwidth emerges as a critical consideration in evaluating optimal display technologies, as it directly influences the speed and clarity of video output both for HDMI 1.4 vs DisplayPort 1.2.

DisplayPort 1.4 showcases a peak bandwidth of 32.4 Gbps, supporting resolutions up to 8K. However, it’s essential to note that video quality may diminish as it approaches this upper limit.

In contrast, HDMI 2.1 offers a substantial bandwidth advantage, boasting 48 Gbps and accommodating resolutions up to 10K. This notable discrepancy positions HDMI 2.1 as the superior choice for bandwidth-intensive video projects. Consequently, if bandwidth stands as a decisive factor for your video endeavors, opting for HDMI 2.1 becomes imperative.

HDMI vs DisplayPort: Maximum Resolution

Understanding the compatibility of your preferred cable with the resolution standards is a crucial step in the pre-purchase phase, particularly when aligning it with your existing display technology. Opting for either DisplayPort 1.4 or HDMI 2.1, no matter how advanced would be futile if it doesn’t correspond with the port specifications of your display device, resulting in wasted resources.

For clarity, DisplayPort 1.4 facilitates resolutions of 4K at 120Hz and 8K at 60Hz. Conversely, HDMI 2.1 offers enhanced refresh rates for these resolutions and extends support to a maximum resolution of 10K, providing a comprehensive spectrum of options for high-definition displays.

HDMI vs DisplayPort: Data Transmission Rate

The data transmission rate signifies the speed at which a data cable can convey information between devices within a given timeframe, typically measured in gigabytes per second (Gbps). This metric holds significant weight in the decision-making process between DisplayPort 1.4 and HDMI 2.1, offering insight into the cable’s suitability for demanding operations.

In this aspect, both cable standards perform admirably. However, HDMI outshines DisplayPort with transmission rates of 48 Gbps compared to 25.92 Gbps, underscoring its superiority in facilitating high-performance data transfers.

HDMI vs DisplayPort: Maximum Refresh Rate

The refresh rate of a display device indicates how frequently it updates the displayed image within a single second, measured in Hertz (Hz). This metric is pivotal in determining the smoothness of video output and the potential for lag or latency issues. For example, a display with a refresh rate of 60Hz refreshes or displays 60 images per second.

In the comparison between HDMI 2.1 and DisplayPort 1.4, both boast commendable refresh rates. However, as the resolution increases, there is a notable decline in refresh rates. DisplayPort’s maximum refresh rate is achieved at 1080p resolution, dropping to 144Hz at 1440p and further to 120Hz at 2K resolution.

Conversely, HDMI 2.1 offers an impressive overall maximum refresh rate of 240Hz. Notably, for HDMI 2.1, all resolutions below 4K maintain this high refresh rate, meaning that the maximum refresh rate for 1440p is also 240Hz, consistent with 1080p and 2K resolutions. However, at 4K resolution, HDMI 2.1’s maximum refresh rate caps at 120Hz.

HDMI vs DisplayPort: Availability

The availability of HDMI 2.1 compared to DisplayPort 1.4 in the market speaks volumes about their respective use cases, market penetration, and accessibility in retail outlets. DisplayPort, while widely accessible, tends to dominate in specialized domains such as workstations and gaming environments, earning its reputation as the go-to choice for gamers over the years.

Conversely, HDMI 2.1 offers versatility across various applications and environments, making it a preferred option for a broader spectrum of users. Its popularity extends beyond gaming circles to encompass professionals, enthusiasts, and individuals utilizing high-resolution monitors and televisions. The prevalence of HDMI 2.1 in the market can largely be attributed to manufacturers prioritizing its integration into a wider array of screens compared to the DisplayPort 1.4 standard.

HDMI vs DisplayPort: HDR Support

HDR (High Dynamic Range) support represents a significant advancement in content display standards, enhancing image accuracy and color reproduction on compatible devices. Therefore, it’s crucial to consider this feature when weighing the merits of HDMI 2.1 versus DisplayPort 1.4.

Broadly speaking, HDMI 2.1 boasts superior HDR support compared to DisplayPort 1.4, primarily due to the introduction of dynamic HDR capabilities in the former. This dynamic HDR support enables precise adjustments on a scene-by-scene basis, optimizing visual quality. In contrast, DisplayPort 1.4 offers static HDR support, limiting the flexibility to adjust dynamic settings between scenes due to its configuration constraints.

HDMI vs DisplayPort: Audio Channel Support

DisplayPort 1.4 and HDMI 2.1 both excel in delivering exceptional audio capabilities, making them standout choices in the realm of audiovisual technology. Notably, their audio functionalities are closely matched, with both supporting up to 32 channels for immersive sound experiences.

Furthermore, HDMI 2.1 impresses with its support for DTS:X and Dolby Atmos, enhancing audio fidelity and spatial immersion. In contrast, DisplayPort 1.4 offers Dolby TrueHD and DTS-HD, ensuring high-quality audio reproduction.

Beyond these similarities, a notable distinction lies in their audio transmission methods. Both DisplayPort 1.4 and HDMI 2.1 efficiently transmit audio signals to and from your sound system. However, the latest iteration of ultra high-speed HDMI cables introduces an enhanced Audio Return Channel (eARC). This innovative feature enables the seamless delivery of preserved, high-quality audio from your display device, minimizing any potential loss in audio fidelity.
