What"s the difference between DisplayPort & HDMI? Whether you"re connecting a monitor and desktop PC, a TV lớn a game console, or setting up your trang chủ theater with a soundbar, you"ve probably wondered about these seemingly similar A/V connections. While DisplayPort and HDMI may look a lot alike, & are used for some of the same purposes, both have some distinct differences.

This guide isn"t going khổng lồ require you lớn slog through the technical aspects of transmission modes, bit depth or màu sắc formats – it"s rarely helpful lớn know this information unless you"re wading into the deeper waters of complex A/V installations. Instead, we"ll cover the most essential information for DisplayPort & High Definition Multimedia Interface (HDMI) connections. Specifically which connections are best for your gear & intended uses, what connection standards tư vấn the resolution and features you want, & which you"re likely to find on your computer and home theater devices.


Let"s start at the most basic and least technical difference between the two standards: The connector.

DisplayPort connections have an asymmetrical shape that looks like a rectangle with one corner lopped off. Inside, you"ll find a 20-pin connector, and the plugs frequently include a physical latch system to secure the cable once it"s plugged in, và requires pressing a latch release lớn unplug the cable.

HDMI, on the other hand, has a symmetrical plug shape, with a 19-pin connector inside. It uses friction lớn stay plugged in, with no latching system. That does make it possible for HDMI cables khổng lồ wiggle loose over time, particularly if you regularly move your devices or jostle the cables behind your desk.

Specs and standards

While these two plugs are both used for đoạn phim connections, there are some pretty major differences between the two in terms of how they function & what data is transmitted. The biggest difference? DisplayPort is often video-only, while HDMI delivers clip and audio in a single cable. But the differences don"t stop there.

DisplayPort versions

There are four different versions of DisplayPort that may be found on monitors và graphics cards, each offering a slightly different mix of tư vấn for different resolutions and frame rates.

DisplayPort 1.2 has been in use since 2010, and offers 17.28 Gbps of bandwidth to handle 4K resolution đoạn phim at 60Hz, as well as any lower resolutions, lượt thích Full HD (1920 x 1080) & Quad HD (2560 x 1440). It also outputs wider aspect ratios and resolutions that offer an expanded field of view. These formats are available on differing variations of DisplayPort, such as Mini DisplayPort và Thunderbolt connections, making this an especially handy format for máy vi tính users.

An updated version of the 1.2 specification, DisplayPort 1.2a, also added tư vấn for AMD FreeSync, which matches the display refresh rate to the frame-by-frame output đầu ra of AMD graphics cards, allowing smoother chơi game without screen tearing.

DisplayPort 1.3 offers even better resolution support, with 32.4 Gbps bandwidth to handle 4K resolution at 120Hz or 8K at 30Hz. Introduced in 2014, it was the first single-cable option for 8K video, other than Ethernet.

DisplayPort 1.4 improved on this slightly, with 60Hz 8K tư vấn and the introduction of HDR10 metadata for high dynamic range (HDR) content. If you have an HDR-capable monitor but are still using an older DisplayPort standard, you"re missing out on HDR gaming.

The 1.4 spec also adds audio transport, making it possible to share sound in addition lớn video, but support for this feature usually requires downloading additional drivers and enabling the feature in settings Many monitors still don"t have built-in speakers lớn take advantage of this capability.

DisplayPort 2.0 is the newest version of DisplayPort, và really ramps things up with wider bandwidth (77.37 Gbps) and support for 10K (10240 × 4320) và even 16K (15360 × 8640) resolution at 60 Hz, with varying levels of màu sắc and compression support. More importantly, it allows for multi-monitor tư vấn at high resolutions & frame rates, handling dual 8K displays at 120Hz or up lớn three 4K displays at 144Hz.

The 2.0 standard was announced for 2020, but thanks to COVID-19 disruptions, 2.0-equipped monitors and graphics cards won"t be sold until the second half of 2021.

HDMI versions

Similarly, the HDMI connection encompasses a number of different specs, with 3 primary popular HDMI standards in use now.

The most commonly used HDMI connection is probably the most basic, HDMI 1.4. It"s capable of delivering 720p or 1080p resolution, and when it was introduced back in 2009, it offered a respectable maximum clip bandwidth of 8.16 Gbps. That made it the first HDMI version capable of delivering 4K picture, but was limited to 24Hz, matching the standard 24 frames per second used by most theater films released on UHD Blu-ray. If you"ve got a 4K TV that"s more than 5 years old, it"s probably still using HDMI 1.4.

The 1.4 standard was also a big change over previous versions, because it included 100 Mbps Ethernet connectivity, which was utilized by some early smart TVs and other connected clip applications. While the majority of smart TVs rely on Wi-Fi and separate Ethernet connections for network connectivity, this additional two-way data flow was an important evolution in the HDMI standard that led to some of the handiest features available today in later revisions.

It"s also the earliest HDMI version to tư vấn audio return channel (ARC), which lets you connect a soundbar using HDMI without running another cable between the TV và speaker set. It"s a cool feature, & one that"s only improved in later HDMI standards.

HDMI 2.0 is sometimes called HDMI UHD, and steps up the bandwidth to lớn 14.4 Gbps, enabling 4K video clip at 60 Hz. While it"s rarely labelled as such, this is a preferred format for many 4K enthusiasts, since it supports 4K 3 chiều material và higher frame rates for 4K gaming. An updated version of the 2.0 standard, HDMI 2.0a, also adds tư vấn for high dynamic range (HDR) content, including HDR10 và Dolby Vision. The majority of 4K TVs on the market in the last five years use this updated 2.0a version.

The most recent, & most capable, version is HDMI 2.1. It offers up to 77.4 Gbps bandwidth and includes support for 8K resolution – something that used lớn require multiple HDMI cables and specialized hardware và software that stitched a quartet of 4K inputs together. With a massive 48 Gbps of bandwidth, HDMI 2.1 actually supports resolutions up khổng lồ 10K.

It"s also capable of supporting 4K resolution at 120Hz, something that high-end TVs have been able to vị for a while, but required playing video from attached storage or using complicated video-over-IP connections. The higher bandwidth also allows for all sorts of new features, like enhanced audio return channel (eARC), variable refresh rates (VRR) & automatic low-latency mode (ALLM). You can learn all about it in our guide What is HDMI 2.1?

What does this mean?

Beyond the basics of plug type, resolution & format tư vấn discussed above, there are all kinds of technical details that we could dig into. Both HDMI và DisplayPort support variations of màu sắc spaces, compression formats, encoding schemes & copy protection standards. And if you want to get into those details, there"s more than enough information out there to lớn read up on.

What you vày need khổng lồ know is that HDMI is the format of choice for trang chủ theater equipment & game consoles lượt thích the PS5 và Xbox Series X. When it comes khổng lồ TVs, soundbars & console gaming, HDMI is king – just make sure you"re using the right cables khổng lồ get all of the features available to lớn you. And if you"re using an inexpensive monitor or a PC that doesn"t have a discrete GPU, it"s HDMI all the way.

Gaming-oriented PCs và monitors, however, have long relied on DisplayPort for its better resolution and frame rate support, especially as technologies like AMD FreeSync and Nvidia G-Sync have become more popular. Professionals that need exacting màu sắc for photo and video clip editing have also preferred DisplayPort for it"s higher technical standards. When visuals matter, pros and enthusiasts prefer DisplayPort.

But this all may change in the coming months, as HDMI 2.1 starts catching up to lớn DisplayPort with its ability to handle 8K đoạn phim and tư vấn those same gamer-friendly features on TVs. The first HDMI 2.1-equipped graphics cards have arrived with Nvidia"s 30 series GPUs, và AMD cards are coming soon.
