HDMI is one of the wires that we often use in our life. After the upgrade of the multi-band version, the two popular HDMI cables on the market are: HDMI cable 1.4 and HDMI cable 2.0, but Many friends don't know the difference between the two. I don't know if I should buy that version of the HDMI cable. Today, I will tell you about the difference between HDMI 1.4 and HDMI cable 2.0.
1, the difference in bandwidth
The bandwidth of HDMI cable 2.0 is 18Gbps, while the previous version of HDMI1.4 bandwidth is 10.2Gbps.
2, the difference in resolution
The hdmi line version 2.0 standard specification has been developed and released, greatly enhancing the support for 4K ultra-high definition transmission, and has been improved on multiple video and audio technologies.
The earlier HDMI1.4, at a bandwidth of 10.2Gbps, can only support 4K@60Hz to the YUV420 color format. The resolution is high, but the picture quality will be lost because the image color compression is too high. Of course, it does not compress so much. It is also impossible to put a 60Hz refreshed 4K resolution image into a 10.2 Gbps bandwidth.
3, frame rate, sampling rate difference
Hdmi 1.4 can already support 4K, but subject to bandwidth, it can only reach 3840×2160 resolution and 30FPS frame rate;
Hdmi 2.0 expands the bandwidth to 18Gbps and supports 3840×2160 resolution and 50FPS, 60FPS frame rate. It also supports up to 32 channels in audio and up to 1536kHz sampling rate.
Ok, after reading the difference between HDMI cable 1.4 and HDMI cable 2.0, do you know the difference between the two? Is it clear which model of HDMI cable you need? If you read it, you still don’t know yourself. If you buy any model, then choose HDMI cable 2.0. After all, it is better than small.
