With a massive 48 Gbps of bandwidth, HDMI 2.1 actually supports resolutions up to 10K. It offers up to 77.4 Gbps bandwidth and includes support for 8K resolution – something that used to require multiple HDMI cables and specialized hardware and software that stitched a quartet of 4K inputs together. The most recent, and most capable, version is HDMI 2.1. The majority of 4K TVs on the market in the last five years use this updated 2.0a version. An updated version of the 2.0 standard, HDMI 2.0a, also adds support for high dynamic range (HDR) content, including HDR10 and Dolby Vision. While it's rarely labelled as such, this is a preferred format for many 4K enthusiasts, since it supports 4K 3D material and higher frame rates for 4K gaming. HDMI 2.0 is sometimes called HDMI UHD, and steps up the bandwidth to 14.4 Gbps, enabling 4K video at 60 Hz. It's a cool feature, and one that's only improved in later HDMI standards. It's also the earliest HDMI version to support audio return channel (ARC), which lets you connect a soundbar using HDMI without running another cable between the TV and speaker set. 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. 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 video applications. If you've got a 4K TV that's more than 5 years old, it's probably still using HDMI 1.4. 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. It's capable of delivering 720p or 1080p resolution, and when it was introduced back in 2009, it offered a respectable maximum video bandwidth of 8.16 Gbps. The most commonly used HDMI connection is probably the most basic, HDMI 1.4. Similarly, the HDMI connection encompasses a number of different specs, with 3 primary popular HDMI standards in use now. ![]() ![]() 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. More importantly, it allows for multi-monitor support at high resolutions and frame rates, handling dual 8K displays at 120Hz or up to three 4K displays at 144Hz. ![]() The 1.4 spec also adds audio transport, making it possible to share sound in addition to 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 to take advantage of this capability.ĭisplayPort 2.0 is the newest version of DisplayPort, and really ramps things up with wider bandwidth (77.37 Gbps) and support for 10K (10240 × 4320) and even 16K (15360 × 8640) resolution at 60 Hz, with varying levels of color and compression support. If you have an HDR-capable monitor but are still using an older DisplayPort standard, you're missing out on HDR gaming. Introduced in 2014, it was the first single-cable option for 8K video, other than Ethernet.ĭisplayPort 1.4 improved on this slightly, with 60Hz 8K support and the introduction of HDR10 metadata for high dynamic range (HDR) content. These formats are available on differing variations of DisplayPort, such as Mini DisplayPort and Thunderbolt connections, making this an especially handy format for laptop users.Īn updated version of the 1.2 specification, DisplayPort 1.2a, also added support for AMD FreeSync, which matches the display refresh rate to the frame-by-frame output of AMD graphics cards, allowing smoother gameplay without screen tearing.ĭisplayPort 1.3 offers even better resolution support, with 32.4 Gbps bandwidth to handle 4K resolution at 120Hz or 8K at 30Hz. It also outputs wider aspect ratios and resolutions that offer an expanded field of view. There are four different versions of DisplayPort that may be found on monitors and graphics cards, each offering a slightly different mix of support for different resolutions and frame rates.ĭisplayPort 1.2 has been in use since 2010, and offers 17.28 Gbps of bandwidth to handle 4K resolution video at 60Hz, as well as any lower resolutions, like Full HD (1920 x 1080) and Quad HD (2560 x 1440). The biggest difference? DisplayPort is often video-only, while HDMI delivers video and audio in a single cable. While these two plugs are both used for video connections, there are some pretty major differences between the two in terms of how they function and what data is transmitted.
