The HDMI interface is used for image transmission. It is said that audio and video signals can be transmitted at the same time, and there is no need to perform digital/analog or analog/digital conversion before signal transmission.
Nowadays, the digital interface has been updated to HDMI2.0b, but now many users understand HDMI 2.0 at the most, because this is close to the most perfect standard, and it is perfectly compatible with 4K resolution. Why is it perfect?
4K has been supported in the HDMI 1.4 version, but some of the limitations have led to imperfections. At that point, we focused on the defective part to expand the bandwidth of HDMI 2.0 to 18Gbps, supporting plug and play and hot. Plug and play, support 3840x2160 resolution and 50FPS, 60FPS frame rate. It also supports up to 32 channels in audio and up to 1536kHz sampling rate. HDMI 2.0 does not define new data lines and connectors, interfaces, so it can maintain perfect backward compatibility with HDMI1.x. The existing Class 2 data lines can be used directly. HDMI 2.0 does not replace HDMI1.x, but is based on the latter enhancement. Any device that wants to support HDMI2.0 must first guarantee the basic support for HDMI1.x.
