How to choose HDMI high-definition cable? HDMI line can transmit audio and video signals at the same time, without the need for conversion between digital and analog signals, and can replace multiple analog transmission lines. HDMI line gradually replaces VGA line, DVI line and other wire, becoming the mainstream audio-visual transmission line.

With the continuous innovation of technology and audio-visual equipment, HDMI line has been developed so far, and it has also been constantly updated to derive different versions of HDMI line. Now, the main HDMI lines on the market are version 1.4 and version 2.0.

When you are watching a movie on 4K TV, if the picture is often delayed, snowflakes or even stuck, in addition to checking the network connection signal and broadcasting equipment failure, you should also pay attention to whether your HDMI cable is version 2.0.

Why should we pay attention to HDMI cable for picture delay and jamming of 4K TV? What is the difference between different versions of HDMI cable? Let's compare HDMI cable of version 1.4 and version 2.0.

Version 1.4 is the earlier HDMI line, which can only achieve a picture refresh rate of 40Hz in the picture transmission with the highest resolution of 1080p. However, in the transmission process of 4K picture, the broadband transmission capacity of the line is obviously insufficient, which can only reach the picture refresh rate of 24Hz. Thus, when playing 4K video source, there will be delay and stuck phenomenon, while version 2.0 can achieve the picture refresh rate of 50 / 60Hz in 4K picture transmission It has to be played more smoothly and naturally.

In terms of color saturation, the HDMI line of version 1.4 only supports 8 bit color depth, while the HDMI line of version 2.0 supports 10 bit color depth. Version 2.0 has a better sense of color hierarchy than version 1.4, and the picture is more delicate and rich, which is more pleasing to your eyes.
