When it comes to connecting devices and transmitting audio-visual signals, two types of cables dominate the market: DisplayPort (DP) and HDMI. Both have their loyal followings, and both have their advantages and disadvantages. But which one is better? In this article, we’ll dive into the details, exploring the features, capabilities, and limitations of each technology to help you make an informed decision.
The Basics: What are DisplayPort and HDMI?
Before we dive into the nitty-gritty, let’s take a step back and understand what DisplayPort and HDMI are.
DisplayPort is a digital video interface developed by the Video Electronics Standards Association (VESA). It was designed to replace VGA and DVI connectors, offering higher bandwidth and versatility. DisplayPort can transmit audio, video, and data signals over a single cable, making it a popular choice for computer monitors, graphics cards, and other devices.
HDMI (High-Definition Multimedia Interface), on the other hand, is a proprietary technology developed by a consortium of companies including Sony, Panasonic, and Philips. It’s primarily used for transmitting video and audio signals between devices, such as from a Blu-ray player to a TV or from a gaming console to a monitor.
Bandwidth and Resolution: The DisplayPort Advantage
One of the most significant advantages of DisplayPort is its higher bandwidth capabilities. DisplayPort 1.4, the latest version, can support up to 32.4 Gbps of bandwidth, while HDMI 2.1, the latest version, tops out at 24 Gbps. This means DisplayPort can handle more data-intensive applications, such as 5K resolutions at 60 Hz or multiple 4K monitors connected to a single device.
In terms of resolution, DisplayPort 1.4 can support up to 5K at 60 Hz, while HDMI 2.1 can only manage up to 4K at 120 Hz. This makes DisplayPort the clear winner for users who require high-resolution displays or multiple monitors.

HDMI supports up to 32 audio channels, including Dolby Atmos and DTS:X, which are essential for immersive audio experiences. DisplayPort, on the other hand, only supports up to 8 audio channels.
HDMI’s audio capabilities make it the preferred choice for home theaters, soundbars, and audio systems. If you’re looking to connect your device to a surround sound system or a high-end audio setup, HDMI is the way to go.
ARC and eARC: Simplifying Audio Connections
HDMI’s Audio Return Channel (ARC) feature allows audio signals to be transmitted from a TV to a soundbar or receiver, eliminating the need for a separate audio cable. The latest version, eARC (Enhanced Audio Return Channel), supports higher-quality audio formats, including Dolby Atmos and DTS:X.
DisplayPort, on the other hand, does not have a built-in audio return channel, requiring a separate audio cable for audio transmission.
Compatibility and Adoption: The HDMI Advantage
When it comes to compatibility and adoption, HDMI is the clear winner. HDMI is widely supported by devices from a variety of manufacturers, including TVs, gaming consoles, Blu-ray players, and soundbars. HDMI is also backward compatible, meaning you can connect an HDMI 2.1 device to an HDMI 1.4 port, albeit with reduced capabilities.
DisplayPort, on the other hand, is primarily used in computer setups, with limited adoption in consumer electronics. While some high-end TVs and monitors support DisplayPort, it’s not as widely adopted as HDMI.
USB-C and Thunderbolt 3: The Future of Connectivity
The rise of USB-C and Thunderbolt 3 has changed the connectivity landscape. These technologies offer faster speeds, higher bandwidth, and versatility, making them ideal for connecting devices. Thunderbolt 3, in particular, uses the USB-C connector and can support DisplayPort, HDMI, and USB signals over a single cable.
As USB-C and Thunderbolt 3 become more widespread, the lines between DisplayPort and HDMI may blur. However, for now, HDMI remains the dominant force in consumer electronics.
Power Delivery: The DisplayPort Advantage
DisplayPort has a significant advantage when it comes to power delivery. DisplayPort Alternate Mode (DP Alt Mode) allows for the transmission of power over the DisplayPort cable, up to 100W, making it possible to charge devices like laptops and tablets.
HDMI, on the other hand, does not support power delivery, requiring a separate power cable for devices.
The Verdict: Choosing the Right Technology
So, is DP or HDMI better? The answer depends on your specific needs and requirements.
If you’re a gamer or professional who requires high-resolution displays, multiple monitors, and high-bandwidth applications, DisplayPort is the clear winner. Its higher bandwidth capabilities, MST feature, and power delivery make it an ideal choice for demanding applications.
On the other hand, if you’re looking to connect your device to a home theater or audio system, HDMI is the way to go. Its superior audio capabilities, ARC and eARC features, and widespread adoption make it the preferred choice for immersive audio experiences.
Ultimately, the choice between DisplayPort and HDMI depends on your specific needs and requirements. Both technologies have their strengths and weaknesses, and understanding these differences is key to making an informed decision.
