Now our most basic digital transmission method in audio and video equipment is to use HDMI to transmit audio and video signals. The daily use of computers, Android or Apple TV boxes, game consoles, and even mobile phones can not be separated from HDMI; Main HDMI version: HDMI1.4 version: The maximum bandwidth is 10.2Gdps, which supports 4K video playback (previous version supports up to 1080P), but due to the bandwidth limitation, the frame rate of its 4K video is only 30 frames per second-not very great when playing 4K video Smooth. HDMI 2.0 version: The maximum bandwidth is 18Gdps, which also supports 4K video playback, and the frame rate has reached 60 frames per second (the performance can be intuitively felt by the naked eye). In addition to the frame rate, 2.0 to 1.4 improvements include: support for simultaneous transmission of dual video streams to multiple users on the same screen, support for 21: 9 ultra-wide display, dynamic synchronization of video and audio streams, and more. HDMI2.1 version: The bandwidth reaches 48Gdps, supports 8K (7680x4320 pixels) video playback at 60 frames per second, and the frame rate of 4K video reaches 120 frames / S. Because the HDMI protocol has perfect backward compatibility, the purchase standard is very simple: the higher the version, the better, but considering that version 2.1 has not been widely used, version 2.0 is completely sufficient for the current stage of use, so it is strongly recommended that everyone When buying a TV, TV box, or computer, choose a device equipped with an HDMI 2.0 interface, and avoid starting with versions less than 2.0-the 1.4 version of HDMI has unsatisfactory picture quality, and it is becoming increasingly rare in the market.
