An overview of DisplayPort versus HDMI
The DisplayPort and HDMI interfaces are used to send audio and video signals to display devices. They are therefore commonly used to connect television screens and monitors. Although each has distinct characteristics, they also affect the display’s quality and performance. Their usefulness is somewhat diverse:
DisplayPort was first designed mainly for PC monitors. For instance, this connection performs well on 4K at 144 Hz or 8K at 60 Hz at high resolution and refresh rates. It also makes possible incredibly complex features, such as multi-display support. Additionally, it integrates state-of-the-art adaptive sync technologies such as FreeSync.
HDMI is the primary interface for TVs, soundbars, and other multimedia devices used for home entertainment. However, HDMI 2.1 has made it simpler to differentiate between HDMI and DisplayPort, allowing it to work with game consoles and apps that play HD videos.
Key Differences
DisplayPort or HDMI will depend on your needs, whether you’re gaming, editing films professionally, or connecting many screens. Both interfaces offer high-quality audio and video, but by understanding their unique features, you can select the one that works best for your setup.
1) eARC, or enhanced audio return channel
DisplayPort: eARC is not supported by DisplayPort by default. Nevertheless, different adaptations or adjustments can be required to transmit the sounds.
High-quality sound is provided by DTS: X and HDMI: Dolby Atmos. Additionally, both DisplayPort and HDMI are made possible via HDMI 2.1’s eARC capabilities. As a result, getting high-quality audio on all devices is easy.
2) A Different USB-C DisplayPort Mode
DisplayPort: The DisplayPort Alternate Mode with USB-C connections allows high-bandwidth audio and video to be sent with a single cable. Additionally, this feature allows for a more efficient connection by doing away with the need for extra connections.
HDMI: USB-C to HDMI adapters are far less versatile than DP Alt Mode. Additionally, it is designed for multiple monitors with increased bandwidth and resolution.
3) Variable Refresh Rate (VRR)
DisplayPort: It makes VRR settings possible, such as NVIDIA’s G-SYNC and AMD’s FreeSync. It avoids tearing and stuttering by employing a synchronised refresh rate between the GPU and display. Gaming monitors are therefore more likely to contain this feature.
HDMI: When VRR capabilities were provided via HDMI 2.1, the gameplay became more fluid. However, the GPU and display may have varying effects on VRR compatibility. As a result, make sure your device supports HDMI 2.1 for optimal performance and refresh rates.
4) Performance
DisplayPort: Compared to HDMI, the display interface has a larger bandwidth. This allows for greater colour depths, faster refresh rates, and better resolutions. It is suitable for screen applications that require great performance. Additionally, it excels in gaming and professional applications.
HDMI: Despite HDMI 2.1’s excellent quality and frame capacity, DisplayPort frequently provides a larger bandwidth. As a result, some pricey apps might not support it.
5) Harmony
DisplayPort: usually present in monitors and PCs. Naturally, there is a common connection between the gaming and professional realms. The device’s use of USB-C with DP Alt Mode also makes it compatible with other devices.
HDMI : The majority of people view HDMI as a standard interface, despite its contentious nature. TVs, home theatre systems, and consumer electronics all employ this familiar interface. As a result, it ensures broad device compatibility.
Technical Differences Between DisplayPort and HDMI
1) Connector design and pin configuration
DisplayPort: DisplayPort connectors come with a single row of 20 pins. To ensure that the connection is tightened, a lock mechanism is also employed. Forceful disconnections are therefore discouraged. Even smaller versions have also been developed, like Mini DisplayPort, which is commonly found on MacBooks.
HDMI: The size of each HDMI connector varies despite having 19 pins. Examples include:
- Type A (Standard): Type A is used by most consumer electronics, TVs, monitors, and home theatre systems.
- The second is Type C (Mini HDMI), which is found in cameras and tablets. Moreover, it is commonly present in a wide range of portable devices.
- Not to be overlooked is Type D (Micro HDMI), a tiny variant commonly seen on action cameras and other devices. It is also more compact than earlier HDMI models.
- Unlike DisplayPort, HDMI lacks a locking mechanism. As a result, the cable may occasionally lose its connection if it is not tight.
2) Maximum Cable Length
DisplayPort: A cable length of no more than 10 feet (3 meters) is required for best performance. More importantly, it is necessary at higher resolutions and refresh rates. Furthermore, signal loss occurs with longer cables.
HDMI: Cables should not be longer than 6 feet (2 meters) for best results. However, they can also penetrate 40–50 feet (13–15 meters) with very little signal loss and very good stability.
3) Multi-stream transport, or MST
DisplayPort: MST is supported by DisplayPort. Multiple monitors can be supported on a single connection thanks to daisy chaining. When a multi-monitor setup is in place, this allows people to use numerous displays at their workplaces, which is beneficial. It may also make the most of the available ports while maintaining the configuration structure.
HDMI: MST and Multistream Transport are not integrated into HDMI. As a result, one HDMI connector is connected to one display in DisplayPort vs. HDMI. Multiple display setups will therefore require additional hardware. This equipment must therefore operate optimally and control several monitors.
Supported Refresh Rates and Resolutions for DisplayPort versus HDMI
