HDMI 2.1 supports 8K HDR

The industry organization who is in the responsibility for the HDMI standards has announced the proposal for features that the next generation version of the standard will provide. The backward compatibility with existing HDMI devices is in the proposal with 8K, 60Hz refresh rate and HDR-quality video or 4K, 120Hz refresh rate video support.

 

4K resolution for those interested in numbers is 3840 x 2160 or 8.3 million pixels and the 8K is 7680 x 4320 or 33 million pixels. The HDMI Forum’s Technical Working Group says the new capacity will provide increased image experience or smoother, more viewable detail in fast-moving scenes.

 




 

Like all new audio-visual qualities, this new standard version is also designed for the future. 4K content only feels its presence in recent times. There are still a few more years when it comes to 8K content screens. We see the first 8K TVs or monitors on the market, but they are more like special products or prototypes designed for photography and design professionals.

 

To take advantage of the HDMI 2.1 version, new displays will need new cabling that supports as much as 48 Gbps of bandwidth. The technical details about the new technology are easy to read, but you need to wait for compatible hardware and content to see the practical use and experience.

 

Interestingly, in the introduction document of HDMI 2.1, 10K resolution is mentioned besides 8K. But at the moment there is no clear information about exactly what it is. However, it is estimated that this is a 16: 9 aspect ratio resolution that has not yet been fully defined and will come from behind 8K. However, the resolution of the combined screen created by combining multiple screens or the ultra-wide version of the 8K screen may be represented as such.

 




 

The new HDMI version will also have a feature called “Game Mode VRR”. As its name implies, the Game Mode VRR will attract the attention of the players. According to the HDMI Forum, this mode supports variable refresh rates and allows the graphics processor unit to display and display an image on the screen.

 

Together with the Game Mode VRR feature of HDMI 2.1, variable frame synchronization is directly incorporated into the HDMI standard. DisplayPort, another audio-visual standard, offers a similar possibility in the name of Adaptive Sync. However, thanks to the popularity of HDMI and the industry-wide support, the impact of the Game Mode VRR can be substantial. We will see more about this new standard when it comes to the end of the year. The HDMI Forum plans to release the final version of the standard in the second quarter of 2017.
