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.

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.
