How to choose HDMI HD cable in daily life?
How to choose an HDMI HD cable? HDMI cables can transmit both audio and video signals at the same time, eliminating the need for conversion between digital and analog signals and replacing multiple analog transmission lines. HDMI cable has gradually replaced VGA cable, DVI cable and other cables, becoming the mainstream audio-visual transmission cable.
With the continuous innovation of technology and audio-visual equipment, the HDMI cable has been developed so far, but also constantly updated, derived from different versions of the HDMI cable. Today, the main HDMI product lines on the market are version 1.4 and 2.0.
When watching a movie on a 4K TV, if the picture is often delayed, snowflakes or even stuck, you should pay attention to whether your HDMI cable is version 2.0, in addition to checking for network connection signals and playback device faults.
Why should you pay attention to HDMI cables? What are the differences between different versions of the HDMI cable? Let's compare the 1.4 and 2.0 HDMI cables.
Version 1.4, an earlier HDMI cable, had a 40Hz refresh rate for images up to 1080p resolution, but the cable's broadband capacity was significantly inadequate for 4K images, with a 24Hz refresh rate. As a result, there will be lag and stuck when playing 4K video sources, whereas Version 2.0 can achieve a 50/60Hz picture refresh rate in 4K picture transfers, so playback must be more smooth and natural.
In terms of color saturation, the 1.4 HDMI cable only supports 8-bit depth, while the 2.0 HDMI cable supports 10-bit depth. Version 2.0 has better layers of color than version 1.4, and the images are richer and more pleasing to the eye.
