When it comes to connecting your devices, whether it’s a gaming console, a computer, or a 4K TV, the type of connection you use can greatly impact the quality of the image and the overall viewing experience. Two of the most popular connection options available today are HDMI 2.1 and DisplayPort. But which one should you use? In this article, we’ll delve into the details of both HDMI 2.1 and DisplayPort, exploring their features, capabilities, and limitations, to help you make an informed decision.
Understanding HDMI 2.1
HDMI (High-Definition Multimedia Interface) is a widely used connection standard that has been around for over two decades. The latest version, HDMI 2.1, was released in 2017 and offers significant improvements over its predecessors. Here are some key features of HDMI 2.1:
- Higher bandwidth: HDMI 2.1 has a maximum bandwidth of 48 Gbps, which is a significant increase from the 18 Gbps of HDMI 2.0. This allows for higher resolutions and faster refresh rates.
- 8K resolution: HDMI 2.1 supports resolutions up to 8K at 60 Hz, making it ideal for future-proofing your setup.
- Dynamic HDR: HDMI 2.1 supports dynamic HDR (High Dynamic Range), which allows for more vivid colors and contrast.
- Variable Refresh Rate (VRR): HDMI 2.1 supports VRR, which reduces screen tearing and provides a smoother gaming experience.
- Auto Low Latency Mode (ALLM): HDMI 2.1 supports ALLM, which automatically switches to a low-latency mode when a game is detected.
HDMI 2.1 Limitations
While HDMI 2.1 offers many impressive features, it’s not without its limitations. Here are a few:
- Cable length: HDMI 2.1 cables can be prone to signal degradation over long distances, which can result in a lower quality image.

What is the main difference between HDMI 2.1 and DisplayPort?
The main difference between HDMI 2.1 and DisplayPort lies in their bandwidth and resolution capabilities. HDMI 2.1 offers a maximum bandwidth of 48 Gbps, while DisplayPort 2.0 offers a maximum bandwidth of 80 Gbps. This means that DisplayPort can support higher resolutions and refresh rates than HDMI 2.1.
In practical terms, this means that DisplayPort can support 16K resolutions at 60 Hz, while HDMI 2.1 can only support up to 10K resolutions at 120 Hz. However, it’s worth noting that most modern devices do not yet support these high resolutions, so the difference may not be noticeable for most users.
Which connection type is more widely supported?
HDMI 2.1 is currently more widely supported than DisplayPort, particularly in consumer electronics such as TVs and gaming consoles. This is because HDMI has been the standard connection type for many years, and many devices have been designed with HDMI ports in mind.
However, DisplayPort is widely supported in the computer industry, particularly in high-end graphics cards and monitors. Many professional-grade monitors and graphics cards use DisplayPort as their primary connection type, so it’s widely supported in these industries.
Can I use an adapter to convert between HDMI and DisplayPort?
Yes, it is possible to use an adapter to convert between HDMI and DisplayPort. However, there are some limitations to consider. For example, an HDMI-to-DisplayPort adapter may not be able to support the full bandwidth of the DisplayPort connection, which could limit the resolution and refresh rate.
Additionally, not all adapters are created equal, and some may not work properly with certain devices. It’s also worth noting that using an adapter can introduce additional latency and signal degradation, which could affect the overall performance of the connection.
Which connection type is better for gaming?
For gaming, HDMI 2.1 is currently the better choice, particularly for console gamers. This is because many gaming consoles, such as the PlayStation 5 and Xbox Series X, use HDMI 2.1 as their primary connection type.
However, for PC gamers, DisplayPort may be a better choice, particularly if they have a high-end graphics card that supports DisplayPort. This is because DisplayPort can support higher resolutions and refresh rates than HDMI 2.1, which could provide a smoother and more responsive gaming experience.
Can I use HDMI 2.1 and DisplayPort at the same time?
Yes, it is possible to use both HDMI 2.1 and DisplayPort at the same time, but it depends on the specific device and its capabilities. For example, some graphics cards may have multiple HDMI and DisplayPort ports, allowing you to connect multiple monitors to the same device.
However, using both connection types at the same time may require some configuration and setup, particularly if you’re using a multi-monitor setup. You may need to configure the device to use both connection types simultaneously, and you may need to adjust the display settings to get the best performance.
Is DisplayPort 2.0 backwards compatible with older DisplayPort versions?
Yes, DisplayPort 2.0 is backwards compatible with older DisplayPort versions, including DisplayPort 1.4 and DisplayPort 1.2. This means that you can use a DisplayPort 2.0 device with an older DisplayPort cable and still get a high-quality connection.
However, to take full advantage of the features and capabilities of DisplayPort 2.0, you’ll need to use a DisplayPort 2.0 cable and a device that supports DisplayPort 2.0. Using an older cable or device may limit the bandwidth and resolution capabilities of the connection.
Will HDMI 2.1 become obsolete with the release of DisplayPort 2.0?
It’s unlikely that HDMI 2.1 will become obsolete with the release of DisplayPort 2.0, at least not in the near future. HDMI 2.1 is still a widely supported connection type, and many devices will continue to use it for years to come.
However, DisplayPort 2.0 may eventually become the preferred connection type for high-end devices and applications, particularly those that require high resolutions and refresh rates. As DisplayPort 2.0 becomes more widely adopted, we may see a shift away from HDMI 2.1 in certain industries and applications.
