HDMI2.1在2018年的市场机型不会出现

以下是HDMI官网发布的HDMI2.1标准新增内容及说明：
HDMI Specification 2.1 Features Include:
 Higher video resolutions support a range of high resolutions and faster refresh rates including8K60Hz and 4K120Hz for immersive viewing and smooth fast-action detail. Resolutions up to10K are also supported for commercial AV, and industrial and specialty usages.
 Dynamic HDR support ensures every moment of a video is displayed at its ideal values for depth,detail, brightness, contrast and wider color gamuts—on a scene-by-scene or even a frame-byframebasis.
 The Ultra High Speed HDMI Cable supports the 48G bandwidth for uncompressed HDMI 2.1feature support. The cable also features very low EMI emission and is backwards compatiblewith earlier versions of the HDMI Specification and can be used with existing HDMI devices.
 eARC simplifies connectivity, provides greater ease of use, and supports the most advancedaudio formats and highest audio quality. It ensures full compatibility between audio devices andupcoming HDMI 2.1 products.
 Enhanced refresh rate features ensure an added level of smooth and seamlessmotion and transitions for gaming, movies and video. They include:
     Variable Refresh Rate (VRR) reduces or eliminates lag, stutter and frame tearing formore fluid and better detailed gameplay.
     Quick Media Switching (QMS) for movies and video eliminates the delay that can resultin blank screens before content is displayed.
     Quick Frame Transport (QFT) reduces latency for smoother no-lag gaming, and real-timeinteractive virtual reality.
 Auto Low Latency Mode (ALLM) allows the ideal latency setting to automatically be set allowingfor smooth, lag-free and uninterrupted viewing and interactivity.The HDMI 2.1 Compliance Test Specification (CTS) will be published in stages during Q1-Q3 2018, andHDMI adopters will be notified when it is available.

也就是说HDMI2.1的CTS测试明年1-3季度才会发布，所以推测市场产品至少要等到19年。

并不妨碍新机预留HDMI2.1方案

明年索尼X1 Extreme将升级成HDMI 2.1+HDMI 2.0方案

普通模式: 4 x HDMI 1.4

增强模式1:  2 x HDMI 1.4 + 2 x HDMI 2.0

增强模式2:  2 x HDMI 2.1 + 2 x HDMI 2.0

增强模式2大约在2018年稍后开始更新

话说dp接口比hdmi还好，怎么就没在电视上普及呢？大法偏向自家的孩子吗？

HDMI Forum 不是索尼一家的

就电视机上的HDMI接口而言，目前韩系的厂商（三星、LG）走在前列，市场的旗舰机型全部更换成了HDMI2.0硬件口，且能够根据片源自动切换至HDMI1.4，算是解决了HDMI2.0不完美兼容1.4的先天不足。而身为保守日系的sony等目前还保留了1.4的硬件口。

都是默认HDMI1.4的,
2.0需要手动开启,并没有什么不完美兼容,或者先天不足之类

1、所谓能调到2.0就表明硬件端口是2.0的标准。默认1.4只是将EDID切到1.4；
2、先天不足指的是HDMI2.0无法完美向下兼容HDMI1.4，这个是HDMI官方承认的。也就是说有些老设备在HDMI2.0下播会有问题，只有将EDID切到1.4才有效，而sony必须手动切，三星LG能够实现自动切换。

我这边LG的不能自动切换,必须手动开启.三星我猜测也应该一样.

2019年会普及 的。就象手机的五G一样。
