HDMI 2.1 VS HDMI 2.0

With the development of science and technology, the latest version HDMI is called 2.1, and it's a big leap forward compared to HDMI 2.0. It's currently found on the best new TVs,  including recent models from LG, Samsung, Sony, TCL and more. HDMI 2.1 is also on both of the game consoles, the PlayStation 5 and Xbox Series X. In fact, to get the most out of those consoles you'll need a TV that supports at least some HDMI 2.1 features.

What is HDMI 2.1? 

HDMI 2.1 is the most recent update of the HDMI specification and supports a range of higher video resolutions and refresh rates including 8K60 and 4K120, and resolutions up to 10K. Dynamic HDR formats are also supported, and bandwidth capability is increased up to 48Gbps. Lately, we’re starting to see AV companies addressing HDMI 2.1 in their next-gen products

What's the difference between HDMI 2.1(8K) and HDMI 2.0(4K)?

HDMI 2.1 supports a maximum transmission bit rate of 48 Gbps, compared with HDMI 2.0's mere 18 Gbps.  All that additional bandwidth opens up the HDMI standard to higher resolutions and refresh rates than it ever had before. 

4K refers to a picture with a resolution of 4096 × 2160 pixels, that is 8.8 million pixels or more. And 8K is as high as 7680 × 4320 pixels, that is more than 33 million pixels, and the number of pixels is as high as 4 times that of 4K!

Gamers will likely be the first to feel the advantages of HDMI 2.1, since video game developers are already promoting 4K games that run at 120FPS.

What application are 8K usually used in?

8K has a very wide range of application scenarios in the medical industry, such as gastroscopes and endoscopes that use images for diagnosis. The higher-definition picture quality will help doctors make accurate judgments. At the same time, ultra-high-definition images can also help doctors perform remote diagnosis, remote surgery, etc.

It can also cooperate with VR technology to provide users with ultra-high-definition content, so that users can have an immersive feeling, which will bring a new way of user participation in the game industry and the video live broadcast industry. Theme parks and large shopping malls can also use ultra-high-definition screens to create richer user interactive advertising or game content. Ultra-high-definition movies will also refresh the visual sense of pleasure once again.

8K will bring profound effects to all aspects of life and work. Thanks to the ultra-high definition display, the picture is more lifelike and precise. With VR/MR/AR technology, holographic projection, remote control and other new interaction modes, it will continuously bring more surprises to life and work.
