从HDMI线引进来的时候已经有着很多不同的家居方式的布线，如何在家中选合适的HDMI线材的版本，用HDMI1.4线，还是HDMI2.0线的版本呢。很多在朋友做装修的时候往往会体验到布线这个问题，现在越来越多的人追赶潮流，看着别人家装着怎样线材就想跟着去追赶，其实布线问题还是有很大的研究的。怎么说，看HDMI2.0 线的解释。
From the HDMI cable when introduced to have a lot of different ways home wiring, how to choose the appropriate home HDMI cable version, with HDMI1.4 line, or HDMI2.0 line version of it A lot of friends in the decoration of the time will often experience the problem of wiring, and now more and more people to catch up with the trend, looking at someone else's home when the wire wanted to follow to catch up, in fact, the wiring problem is still a lot of research. How to say, look at the interpretation of HDMI2.0 line.
首先看HDMI1.4版，带宽达到10G/S，能支持4K（2160P）@30HZ视频播放，是当下HDMI领域比较成熟的技术应用。在协议这一块，最好要选择一根4K的HDMI线，家里的设备是不断更新的，而埋在墙里的HDMI线是难以替换的。一个家庭影院的音视频效果，是由整个系统的设备配合来达到的，而决定能达到的程度是由系统最弱那一环决定的，木桶原理我就不再赘述了。
First look at HDMI1.4 version, bandwidth up to 10G / S, can support 4K (2160P) @ 30HZ video player, is the current field of HDMI technology is more mature. In the agreement this one, it is best to choose a 4K HDMI cable, the home device is constantly updated, and buried in the wall of the HDMI cable is difficult to replace. A home theater audio and video effects, is the system with the equipment to achieve, and decided to achieve the extent of the system is determined by the weakest, the principle of the barrel I will not repeat them.
看HDMI线的协议就能知道这种线材为何要这样选择了。
See the HDMI cable protocol can know why this wire to choose this.
现在HDMI2.0带宽已到18G/S,这是VGA（1080P）和DVI达不到的，意味着可以播放4K（2160P）@60HZ的视频，当然目前还没有详细的测试规范，很多厂商标称HDMI2.0，但未必达到这个带宽，且线材较粗较短较贵，多采用纯银材质。对于距离在5米以上的HDMI2.0铜线，且只卖几百块，我是表示质疑的。但是适用于家庭影院的长距离HDMI2.0线已经离普通用户不远了。
HDMI2.0 bandwidth is now to 18G / S, which is VGA (1080P) and DVI reach, means that you can play 4K (2160P) @ 60HZ video, of course, there is no detailed test specifications, many manufacturers nominal HDMI2.0, but may not reach this bandwidth, and the wire is relatively thick and relatively expensive, more use of sterling silver material. For more than 5 meters away from the HDMI2.0 copper wire, and only sell a few hundred, I was questioned. But for long-distance home theater HDMI2.0 cable has been far away from the average user.
