HDMI vs DisplayPort: Difference and Comparison

There are several interface options available to users today with advancements in technology. However, the right choice for an individual varies depending upon their requirements and the budget.

HDMI and DisplayPort are two such interfaces that allow transferring audio and video content from one device to another. However, they have considerable differences.

Key Takeaways

  1. HDMI supports a wide range of devices, such as TVs and gaming consoles, while DisplayPort provides better support for monitors and professional displays.
  2. DisplayPort can daisy-chain multiple monitors, whereas HDMI requires a separate cable for each display.
  3. HDMI features Consumer Electronics Control (CEC) and Audio Return Channel (ARC), enabling easier control of connected devices and audio transmission.

HDMI vs DisplayPort 

HDMI, or High-Definition Multimedia Interface, is commonly used in home entertainment systems, TVs, gaming consoles, and other multimedia devices. DisplayPort is a digital display interface used primarily for computer systems, monitors, and graphics cards, having a higher refresh rate.

The newer versions of HDMI offer several advanced features. There has been a rise of the colour bit depth to 12-bit colour deep. An HDMI forum came into existence on 25 October 2011 to facilitate specifications in HDMI advancements. 

Displayport refers to an audio and video transfer technology that allows a 3X increase in video bandwidth performance. Displayport also offers resolutions as high as 8k to its users.

The range of the video signal path varies from six to sixteen bits per colour channel. The signal protocol employed by DisplayPort is the LVDS signal protocol. It also offers users a high HDR range and higher refresh rates.

What is HDMI?

HDMI stands for High -Definition Multimedia Interface. HDMI serves as an audio and video interface that transmits uncompressed video data.

HDMI also serves the function of compressing or uncompressing digital audio data. Over the years, HDMI has replaced analogue video standards. Some HDMI-compliant source devices are video projectors or digital audio devices.

HDMI was designed in December 2002. HDMI seeks to implement the EIA/CEA-861 standards. There has been a rise of the colour bit depth to 12-bit colour deep.

An HDMI forum came into existence on 25 October 2011 to facilitate specifications in HDMI advancements.  Several versions of HDMI have been available in the market ever since the advent of the technology.

However, the similarity among all the models of HDMI is that they use the same connector and cable.

HDMI products hit the global market in late 2003. The newer versions of HDMI offer several advanced features.

Some of the features of HDMI are improved video and audio capacity, resolution and colour spaces, 3D features, data connection, performance, and CEC extensions.

The CEC feature of HDMI allows HDMI devices to control each other whenever required. 

HDMI is not an open standard service. Consequently, manufacturers must obtain a license from HDMI LA to incorporate HDMI into any component.

DVI is the only interface with the authority to utilise HDMI without a license. There are specific protocols, electrical interfaces, signals, and mechanical requirements of HDMI standards.

What is DisplayPort?

Displayport refers to a digital display interface that primarily serves to connect a video source to a display device. Some devices compatible with DisplayPort are USB and computer monitors.

Video Electronics Standard Association has standardized Displayport. There are numerous manufacturers of DisplayPort.

The objective of DisplayPort is to replace FPD-link, VGA, and Digital Visual Interface. A unique feature of DisplayPort is its reliance on packetized data transmission.

As a result, DisplayPort allows the use of internal and external display connections. The DisplayPort protocol is derived from micro-packets allowing clock signals to be merged with data streams.

Displayport allows users to transfer both audio and video content simultaneously. However, the audio and video content can also be transmitted individually.

The range of the video signal path varies from six to sixteen bits per colour channel. The signal protocol employed by DisplayPort is the LVDS signal protocol. 

Displayport offers a multi-stream transport feature. The features allow the simultaneous processing of several independent displays into a single stream.

In addition, DisplayPort offers the High Dynamic Range feature to the users. A prominent advantage of DisplayPort is the expansion of the standard with several data types.
