How powerful is HDMI 2.1? What is the difference between HDMI 2.0? It’s really scary after reading it!
Because the Android tv box is using HDMI links, so let's take a look at the difference between HDMI today.
With the continuous emergence of various types of high-definition devices, it is particularly important for the TV interface. Then, among the many interfaces of flat-panel TVs, one of the most important interfaces is the non-HDMI interface.
A friend who knows a little about flat-panel TVs knows that the HDMI interface is used to connect external HD devices. Compared with the earlier VGA interface and color difference interface, the HDMI interface has the advantage of transmitting audio and video signals at the same time without signal transmission. Perform digital/analog or analog/digital conversion before. This interface configuration is available regardless of whether it is a TV box or a smart TV.
HDMI released the first generation version in 2002, and there have been several versions since its development. The mainstream is only 1.4, 2.0, 2.1, HDMI supports high version compatible with the low version, but the performance and user experience are far apart.
HDMI1.4 version only supports 4K video playback of 30 frames per second, video fluency is not enough, long-term viewing is easy to cause visual fatigue;
HDMI2.0 version supports 4K video playback of 60 frames per second, the video effect is very ideal, not stuck, it is also mild to the human eye, is the standard interface of the current 4K industry;
HDMI2.1 version supports 4K video playback of 120 frames per second, and also supports 8K video playback of 60 frames per second. It is extremely fast and has no stagnation. It is also very gentle to the human eye. It is necessary for data transmission in the future 8K and 10K eras. interface.
Based on the above comparison, it is obvious that the HDIMI1.4 version has poor performance, and HDMI2.0 is still a good choice.
In fact, HDMI2.0 also has two versions of HDMI2.0a/HDMI2.0b. Although the HDMI 2.0b version is updated, HDMI2.0a has a higher level, HDMI 2.0b supports 10.2G bandwidth, and HDMI 2.0a supports 18G bandwidth. Both support 4K@60Hz, but if it is HDMI 2.0b, it will be worse in terms of color depth and color bit.
to sum up:
In the long run, the HDMI 2.1 version of the interface is more worthy of choice, because it is more forward-looking, and future 8K, 10K TVs need it to achieve transmission and enjoy a better viewing experience.
Finally, I suggest you buy a smart TV or TV box, you must choose HDMI2.0 interface or above. Then you can download Google paly to install a variety of TV-side video software with 4K content, such as KODI video, netflix, etc. to expand a large number of film and television drama resources.
